The Continental National Plan

Freight, diesel sovereignty, and flood-proof rail. Australia depends on diesel trucks for freight; imports 80–90 % of its refined fuel; has 30–37 days of stock; runs one vulnerable rail line each to Perth and Darwin that has been cut by floods three times in four years; and has committed to net zero with no plan to electrify the freight that runs the country. This memo sets out the continental answer — six Sovereign Build Corridors, every Australian port and airport on the network, elevated and flood-proof, electric from day one.

1. The Crisis That Has Already Begun

In early 2026, multiple things happened at the same time. The Strait of Hormuz was constrained by regional conflict, disrupting the shipping routes that carry roughly half of Australia’s diesel imports. Six tankers carrying refined products from Malaysia, Singapore and South Korea were cancelled or deferred. South Korea, which supplies about a quarter of Australia’s diesel imports, capped its refined product exports at 2025 monthly average levels. The federal Energy Minister confirmed Australia held 34 days of diesel, 32 days of jet fuel, and 36 days of petrol — the “highest in 15 years”, but still well below the International Energy Agency’s 90-day benchmark and far below the 200+ days held by Japan and South Korea. The government relaxed diesel specifications to widen supply options. Australia turned to the United States as an emergency supplier — the first time in decades.

Meanwhile, between 23 February and 18 March 2026, the Trans-Australian Railway — the only freight rail link from the east coast to Perth across the 1,693 km Nullarbor — was cut by flooding. It opened, was cut again the next day, was cut a third time the following week. Five separate washaways. Specialised equipment and materials had to be transported into “very remote locations” over days and weeks. The same network is the only freight rail link to Darwin. Multiple highways were simultaneously disrupted by the same flooding event. Western Australia and the Northern Territory were, for practical freight purposes, isolated from the eastern states by weather.

This was the third time in four years (2022, 2024, 2026) that the Trans-Australian Railway has been cut by flooding. The Australian Rail Track Corporation has invested in culvert upgrades and drainage works after each event. The flooding has continued to cut the line. The rail line is at ground level, in flat terrain, in country that floods on a 4-year-or-better cycle. The engineering answer to flooding a ground-level rail line in flat terrain is not better culverts. It is to elevate the rail line.

These two events — the fuel crisis and the rail flooding — are not unrelated. They are the same problem viewed at different time horizons. Australia’s national freight system depends on (a) imported diesel running (b) ground-level vulnerable rail and road, in a country whose climate is now visibly making (b) less reliable while geopolitics is making (a) more constrained. Neither problem has an active national response at scale.

This memo is not arguing that Australia should build continental electric rail because it would be nice. It is arguing that Australia must build continental electric rail because the system we have, the system we depend on every day, is structurally fragile in ways the recent weather and the recent geopolitics have made undeniable. We have known this. We have done nothing about it. The MMC platform is the plan that exists.

2. The Diesel Dependency

2.1 The numbers

Australia’s liquid fuel position is the worst of any International Energy Agency member country. The key facts, all from current government and industry sources:

• Imports approximately 80–90 % of refined transport fuel. Domestic refining now supplies just 17 % of demand; domestic crude oil production supplies 5.6 %.
• Has the world’s largest refined-petroleum trade deficit. Largest by a wide margin, according to IEEFA analysis.
• Holds 30–37 days of fuel stocks. The IEA benchmark is 90 days. Japan and South Korea hold 200+ days. Thailand holds 95 days.
• Has only two operating refineries left. Down from eight in 2000. Ampol’s Lytton (Brisbane) and Viva Energy’s Geelong are what remains.
• Approximately half of Australia’s diesel imports pass through or originate from refineries dependent on the Strait of Hormuz. South Korea alone, which is exposed to Middle East crude inputs, supplies roughly 120,000 b/d of diesel.

The transport sector uses 75 % of Australia’s liquid fuel demand. The transport sector is approximately 98 % reliant on liquid fuels. Of total transport fuel, road freight is the largest single use. Mining and agriculture, which sit outside the transport sector but are critical to the export economy, are over 90 % reliant on diesel. Mining diesel demand has grown at 7.9 % per year.

This is the freight system that runs Australia. Imported diesel, two refineries, 30-day stocks, exposed to geopolitical chokepoints half a world away.

2.2 The 2026 crisis as preview

The events of March 2026 are not a worst-case scenario. They are a moderate-case scenario in which the Strait of Hormuz remained “constrained, not closed”, in which Asian refineries continued to operate but limited exports, and in which Australia found alternative suppliers (United States, India). The crisis was managed. Fuel kept arriving. The government’s response — relaxing diesel specifications, securing emergency US imports, drawing down the modest stockpile — was competent within the constraints.

But the constraints are absurd. Australia, a wealthy, advanced, democratic country, was running its national freight system on 30 days of diesel stock. The crisis exposed how fragile that is. A real Strait of Hormuz closure, a real Asian refinery shutdown, a real shipping route disruption longer than a few weeks — any of these would have cut into the national freight system within weeks, not months. The economic damage would have been substantial within a fiscal quarter.

The Australian Government’s response to the events of 2026 has so far been to extend storage capacity, secure additional emergency imports, and continue the slow rollout of electric vehicle policy. There is no national plan to reduce structural dependence on diesel for freight. The IEEFA, in its March 2026 briefing, was explicit: “electrification is the most promising solution as it is mature, cost-effective and can deliver reductions in oil imports at scale, which can be offset with domestically supplied clean energy.” The technology exists. The renewable electricity exists (see MMA Memo 1 on the 1,000 GW solar resource). The corridor structure to carry that electricity to load and to carry electric freight on it does not exist. That is the gap MMC fills.

3. Net Zero Means Electrifying Freight, Not Just Cars

Australia’s commitment to net zero by 2050 is a serious legal and policy obligation. It is also, for the transport sector, almost entirely focused on light passenger vehicles. The conversation about electric vehicle uptake, charging infrastructure and battery supply chains has been almost exclusively about cars. Cars are 19 % of national transport emissions. Heavy road freight, rail, shipping, aviation, mining, and agricultural diesel use are the remaining 81 %, and almost none of it has a credible electrification pathway in current policy.

The hard-to-abate transport sectors are hard to abate precisely because they need three things at once: high-energy-density fuel, continental range, and heavy duty cycles. Battery-electric solutions work brilliantly for light vehicles with predictable urban or regional routes. They struggle for B-triple road trains running 3,000 km Melbourne to Perth, for harvest fleets working 16-hour days during a six-week window, for iron ore trains hauling 30,000-tonne payloads across the Pilbara.

For these sectors, the answer is not battery-electric trucks doing the same job as diesel trucks. The answer is electric rail doing the long-haul work, with battery-electric or hydrogen first/last-mile vehicles connecting the rail terminals to the farms, mines, and ports. The corridor carries the energy and the freight at the same time. The truck’s job becomes a 50-200 km regional delivery using a battery that can be charged from the corridor’s transmission deck. Diesel disappears from the long-haul stage of the freight chain entirely.

This is not a technology bet on a future invention. Electric freight at corridor speeds is operationally proven in China (continental electric freight at scale across thousands of kilometres), Switzerland (the Gotthard Base Tunnel and the Swiss freight network are nearly entirely electric), and Russia (the Trans-Siberian, electrified end-to-end). The technology is mature. What is missing in Australia is the corridor.

4. The State of Australian Continental Rail

4.1 One line to Perth, one line to Darwin

Australia’s continental rail network, as it currently exists, is:

• The Trans-Australian Railway — Sydney/Melbourne to Perth via Adelaide and the Nullarbor. 4,352 km Sydney to Perth. Single track over most of its length. Mixed diesel-electric and diesel haulage. Freight average speed approximately 50–60 km/h. Cut by floods three times in four years (2022, 2024, 2026).
• The Adelaide–Darwin Railway — Adelaide to Darwin via Alice Springs. 2,979 km. Single track. Diesel-only freight. Operated by a private consortium (One Rail Australia, formerly Genesee & Wyoming Australia / Aurizon). Carries the bulk of food and essential supplies into the Northern Territory.
• The Melbourne–Brisbane corridor via Sydney — the busy east-coast freight corridor that Inland Rail was attempting to bypass. Approximately 1,700 km via the coastal route. Shared with passenger services through the Sydney bottleneck. Now back to road-dominant freight after Inland Rail’s northern half was cancelled in May 2026.
• State-based regional networks — agricultural and resource branch lines of varying age and condition, mostly built in the 19th and early 20th centuries, mostly diesel-hauled, mostly serving narrow specific commodities (grain, coal, iron ore, sugar).

That is the network. Two transcontinental single-track diesel lines, one cancelled inland freight project, and a patchwork of legacy regional rail. This is the freight infrastructure of a country that exports continental quantities of food, energy and minerals, and imports continental quantities of manufactured goods, fuel and inputs. It is not adequate to the task. It has not been adequate for thirty years.

4.2 The flood vulnerability is structural

The repeated flood closures of the Trans-Australian Railway between 2022 and 2026 are not random weather events. They are the predictable consequence of running ground-level rail across flat country in a climate that produces concentrated rainfall events on a 2-4 year cycle. The same flat terrain that makes the rail line cheap to build also makes it vulnerable to flash flooding. Culvert upgrades reduce some flooding risk; they do not eliminate it. Three flood closures in four years is not a culvert-upgrade problem; it is a fundamental alignment problem.

The MMC platform’s elevated viaduct design — standard corridor height 6–8 m above flat ground — sits above the flood level by design. Roads continue underneath. Livestock cross underneath. Watercourses run underneath. Major flood events that wash out a ground-level rail line do not reach the corridor deck. The same elevation that gives the MMC platform clear airspace for electric overhead transmission, that allows agrivoltaic farming under the corridor, that lets freight terminals descend on dedicated off-ramps to ground level — that same elevation makes the entire corridor flood-resilient by default.

This is not a marginal benefit. The economic cost of the three Trans-Australian Railway flood closures since 2022 runs into hundreds of millions of dollars in supply chain disruption, emergency road freight substitution, and ARTC repair work. A continental network built at ground level will keep flooding. A continental network built at standard MMC corridor height will not.

4.3 Speed and electric haul

The MMC freight specification is electric haul at corridor speed (up to 250 km/h). The current Trans-Australian Railway runs diesel-electric or pure diesel haulage at an average ~50–60 km/h with maximum freight speeds typically capped at 110 km/h. The MMC corridor is approximately four times faster than the existing transcontinental line and electrically powered end to end.

Four times faster matters because the perishable goods that Australian agriculture produces (live cattle, fresh produce, dairy, seafood) currently must be air-freighted or road-trucked to compete with refrigerated truck timelines. Electric rail at 250 km/h, with proper cold-chain integration, brings rail freight into competition with road freight for time-sensitive cargo for the first time in Australian history. Mining bulk, agricultural grain, manufactured exports — all become commercially viable on rail at MMC corridor speeds in a way they are not on current 50-60 km/h diesel-hauled networks.

5. The Continental Network — Six Sovereign Build Corridors

The continental MMC network is delivered as six Sovereign Build Corridors (SBC) beyond Phase 0, supplemented by Phase 1-1 (the Perth-Albany link). Each corridor is named for its primary economic and strategic function.

Total continental network beyond Phase 0: approximately 17,400 km. Combined with Phase 0 (2,284 km) and its seven east-coast spurs (3,360 km), the full MMC network reaches approximately 23,200 km. Every state capital. Every major regional centre over a defined population threshold. Every major Australian commercial port. Every major Australian airport. One platform, one engineering, one consortium delivery.

5.1 SBC #1 Brisbane to Perth — the east-west spine

SBC #1 is the corridor that the Trans-Australian Railway has been failing to be for fifty years. 3,519 km from Brisbane through inland NSW, the Riverina, Adelaide, the Nullarbor, the WA goldfields, and into Perth. Electric freight at 250 km/h. Passenger maglev at 600 km/h. HVDC transmission carrying electricity from the central Australian Solar Regions to both coasts.

The strategic significance is hard to overstate. Australia currently has one rail line linking its two largest cities on the eastern and western coasts — a vulnerable, flood-prone, diesel-hauled, single-track legacy line. SBC #1 replaces that with a continental tri-modal corridor that is structurally faster, structurally electric, and structurally above flood level. A second physical link between east and west would be infrastructure resilience even if it were single-mode; as a tri-modal corridor it is transformational.

SBC #1 also provides the eastern delivery point for inland solar generation. The four central Australian Solar Regions identified in MMA Memo 1 sit close to SBC #1’s alignment. Solar electricity generated north of Alice Springs reaches the east coast on the SBC #1 transmission deck and the SBC #2 alignment. The same corridor structure that moves freight moves the electricity that the freight will eventually run on.

5.2 SBC #2 Darwin to Adelaide — the north-south spine

SBC #2 is the continental north-south backbone. 2,661 km from Darwin through Katherine, Tennant Creek, Alice Springs, Coober Pedy, and Port Augusta to Adelaide. Replaces the Adelaide-Darwin Railway as the principal freight link to the Northern Territory, with electric haul, passenger service, transmission, and continental capacity.

Darwin’s strategic role is changing rapidly. Asian trade, defence positioning, gas export, and northern Australian development all converge on Darwin. The current single-track diesel rail link is inadequate for a port that aspires to be Australia’s northern gateway. SBC #2 brings Darwin into the continental network properly — with capacity, speed, and multi-modal integration that turns the city from a remote terminus into a corridor city.

Alice Springs, which sits at the midpoint of SBC #2 and at the eastern edge of the central Australian Solar Regions, becomes a major continental hub: rail junction, solar generation centre, transmission interchange, and the gateway to the Alice Hub pumped hydro energy storage system documented in the SBC Consortium Prospectus.

5.3 SBC #3 Albury to Karumba — the inland north-south

SBC #3 (2,238 km) runs from Albury on the Victorian/NSW border up through inland NSW and Queensland to the Gulf of Carpentaria port of Karumba. It provides a second north-south spine through the inland, parallel to but well east of SBC #2, serving the inland agricultural belt of NSW and Queensland and the cattle country of the Gulf.

The Gulf of Carpentaria has long been identified as a potential bulk export gateway to Asia but has lacked the rail infrastructure to compete with established east-coast and Pilbara ports. SBC #3 changes that economic geography. Combined with SBC #1 and SBC #2, it gives the central Australian agricultural and mineral belt three different rail paths to coastal export points.

5.4 SBC #4 Mackay to Port Hedland — the trans-northern resource corridor

SBC #4 (3,178 km) is the trans-northern resource corridor. It runs from Mackay on the central Queensland coast through Mount Isa and the mineral provinces of north-western Queensland, across the Top End, and into the Pilbara at Port Hedland. The corridor connects the world’s largest iron ore export port (Port Hedland) to the Queensland east-coast bulk ports (Gladstone, Mackay), and threads the major Northern Australian mineral provinces along the way.

The Pilbara is already heavily railed at a regional scale (the dedicated heavy-haul iron ore lines of Rio Tinto, BHP, and Fortescue). What SBC #4 adds is integration: connecting the Pilbara to the eastern bulk ports via a continental electric corridor, with passenger and transmission service on the same alignment. The corridor opens the inland Western Australian mineral provinces (currently isolated by distance) to coastal export. It also creates the option for renewable hydrogen, ammonia and other electrically-produced commodities to move between the Pilbara’s wind and solar resource and the east-coast industrial centres.

5.5 SBC #5 Derby to Esperance — the western coastal corridor

SBC #5 (1,871 km) is the Western Australia coastal corridor, running from Derby in the Kimberley through Broome, Karratha, Geraldton, Perth, Bunbury, and Albany to Esperance. It is the WA equivalent of the east-coast Phase 0 corridor — a coastal multi-modal viaduct linking the western Australian state economy together, with every WA port on the network.

SBC #5 carries the same tri-modal architecture — electric freight, passenger maglev, HVDC transmission — adapted for the Western Australian context. The Pilbara connection (Karratha, Port Hedland, Dampier) is the heaviest freight section. The Perth metropolitan section integrates with the local rail network. The southern WA section (Bunbury, Albany, Esperance) opens the southern agricultural and resource regions to the same continental network.

5.6 SBC #6 Albany to Port Douglas — the long northern connector

SBC #6 (3,542 km) is the longest single corridor in the network. It runs from Albany in southern Western Australia, north through the WA wheatbelt, across the Top End, and down through Cape York to Port Douglas in far north Queensland. It is the final integrative corridor, connecting the SBC #4 trans-northern resource spine to the southern WA and far-north Queensland regions and creating multiple resilience paths through the continental network.

SBC #6 is also the corridor most directly relevant to climate resilience. It runs through some of the most flood-prone country in Australia (the Cape York wet season, the Top End monsoon, the Kimberley flood-plains). Elevated viaduct architecture is not a nice-to-have on SBC #6 — it is a structural requirement. Built at standard MMC corridor height, the line stays open through the wet season. Built at ground level, it would close annually.

6. Every Australian Port and Airport on the Network

6.1 The continental ports

The continental phases bring every major Australian port outside the east coast onto the MMC freight network. Combined with the east-coast ports listed in MMA Memo 2, the full network reaches every commercial port that matters to the Australian economy.

Combined with the east-coast ports already on Phase 0 and its spurs (Melbourne, Geelong, Eden, Botany, Port Kembla, Newcastle, Brisbane, Bundaberg, Gladstone, Mackay, Townsville, Cairns, Adelaide), the full MMC network reaches every major Australian commercial port. The precise final alignment of each corridor is for the delivery consortium to optimise against terrain, environmental and indigenous considerations. The principle is clear: every port that matters to the Australian economy is on the network, with direct electric freight access on a single integrated platform.

6.2 The continental airports

The continental phases bring the remaining major Australian airports outside the east coast onto the MMC passenger network.

Combined with the east-coast airports on Phase 0 (Melbourne, Avalon, Adelaide, Canberra, Sydney, WSA, Newcastle, Gold Coast, Brisbane, Sunshine Coast, Townsville, Cairns), the network reaches every Australian airport with substantial passenger traffic. Twenty-three airports in total. Approximately 165 million passenger movements per year, all on one integrated rail network.

Tasmania is integrated by a future undersea spur from the Phase 0 corridor near Melbourne. The technology — underwater rail tunnel — is operationally proven (Channel Tunnel, Seikan Tunnel, Boknafjord crossings). The economics are challenging but defensible at the network scale that the rest of the MMC platform delivers. Tasmania is addressed in a future memo when the design and economics are ready.

7. Mining and Agriculture — The Revitalised Freight

7.1 Mining

Australian mining is over 90 % reliant on diesel. The diesel demand has grown at 7.9 % per year. Mining is also the largest single user of road freight in continental Australia — B-triple road trains hauling bulk minerals across thousands of kilometres of remote highway. The mining diesel bill alone is in the billions of dollars per year, and most of that diesel is imported.

The MMC network changes mining freight economics fundamentally. The continental SBC corridors connect every major Australian mining province (Pilbara iron ore, Mount Isa copper-zinc, Bowen Basin coal, Surat Basin gas, NT manganese and uranium, WA gold and nickel, Eyre Peninsula iron, Cape York bauxite) to the closest coastal port via electric freight. The diesel bill collapses. The carbon footprint collapses. The supply-chain resilience improves because the rail line stays open through floods that close the road network.

The miners themselves are some of the most sophisticated infrastructure operators in the world. Rio Tinto, BHP, Fortescue, Glencore and others already run dedicated heavy-haul rail in the Pilbara and Bowen Basin. They understand the economics of electric freight rail at scale. They are also some of the most exposed companies to net zero scope-3 emissions accounting. SBC #1, #4 and #5 are corridors that mining co-investors have a direct commercial interest in delivering. The SBC programme’s consortium structure (set out in the SBC Consortium Prospectus) is designed to make mining co-investment a core financing component.

7.2 Agriculture

Australian agriculture is also over 90 % reliant on diesel — tractors, harvesters, trucks, refrigeration, pumping. The export commodity flow (wheat, barley, canola, sugar, cotton, wool, beef, lamb, fruit, wine) currently moves from farm to port by a combination of road truck, ageing regional rail, and direct truck haul to port. Costs per tonne-kilometre on this fragmented network are high, particularly for time-sensitive perishables.

The MMC network revitalises rail freight as the primary long-haul mode for agriculture. The Phase 0 east-coast spurs (Phase 0-4 north Queensland, Phase 0-5 Brisbane to Port Macquarie, Phase 0-6 Melbourne to Adelaide, Phase 0-7 Canberra to Eden) bring the major east-coast agricultural regions onto the network. The continental corridors (SBC #1 through the inland NSW and SA wheatbelt, SBC #3 through the Queensland and NSW agricultural belt, SBC #5 through WA wheat country) bring the remaining agricultural belts onto the network.

At 250 km/h electric freight with proper cold-chain integration, perishable agricultural products from regional Australia reach east-coast and Asian export ports in hours rather than days. Fresh produce, dairy, seafood, premium beef and lamb — the high-value categories that Australia is best positioned to export — gain a freight system that supports their premium positioning rather than constrains it. The regional Australian economy gains a transport spine it has lacked for sixty years.

Agrivoltaic farming under the corridor (set out in MMA Memo 1) further integrates the agricultural and energy roles. The same elevated corridor that carries farm produce to market also generates solar electricity at 3–5 m clearance above the working farm beneath. Two land uses on one easement. Continental scale agrivoltaic operations supported by the solar resource modelled in MMA Memo 1.

7A. When the Line Goes Down — What Happens to Ordinary People

The Trans-Australian Railway moves approximately 80 % of the supermarket goods consumed in Western Australia. When the line is cut, the consequences are not an abstract supply-chain problem in a quarterly report. They are direct, household-level consequences for the people living in WA and the NT.

7A.1 The 2022 closure — what it actually meant

When the Trans-Australian Railway was cut by flooding in January 2022 and remained closed for 24 days, the head of Independent Food Distributors Australia described it as “the worst disruption to the food supply chain into Western Australia in living memory”. Coles and Woolworths introduced buying limits. Supermarket shelves emptied. The goods that disappeared first were the most basic items in any household: pasta, sugar, toilet paper, medicines, sanitary items, meats and frozen foods. Perishable items already in the supply chain — dairy, cream, bacon, pork — had to be dumped because they could not be re-routed before spoilage.

Woolworths resorted to shipping goods into WA by sea to attempt to refill shelves. The State Government set up an emergency “land bridge” freight service to truck goods across the Nullarbor on the parallel Eyre Highway — an inadequate substitute that delivered a fraction of normal rail volumes, with diesel road trains crawling across the same desert that had just defeated the rail line. Foodbank WA, which feeds vulnerable West Australians, saw its national deliveries collapse from 40 pallets per week to zero. Communities that depend on charitable food distribution simply ran out.

The disruption did not end when the line reopened. The backlog of accumulated goods took four to six weeks to clear, with normal supermarket stocking patterns disrupted long after the trains were running again. The 2024 and 2026 closures repeated the pattern with variations — different stretches of track, similar consequences for households.

7A.2 Medicines, not just groceries

The Guardian’s 2022 reporting noted that medicines were among the items running short in WA pharmacies during the closure. This is the consequence of building a national medical supply chain on a single ground-level rail line and a parallel highway through flood-prone outback country. Time-sensitive medications, vaccines requiring cold chain, hospital supplies, pharmaceutical inventories — all of them move on the same vulnerable network as the groceries. When the network fails, people who depend on those medications are in real, immediate danger.

This is not a theoretical risk. The 2022 closure produced documented pharmacy-level shortages. The 2024 and 2026 closures have produced the same pattern. The country is one extended flood event — one Strait of Hormuz closure, one simultaneous weather system that takes out both the rail line and the parallel highway — from a genuine medicines emergency in WA or NT. Hospitals, aged care facilities, regional health services, remote Indigenous community clinics: all of them are downstream of the same fragile freight network.

7A.3 Fuel itself, on the wrong side of the cuts

The line-cut consequences extend to fuel itself, the very commodity that the diesel-dependency argument turns on. In March 2026, during the Strait of Hormuz crisis that exposed Australia’s 30-day fuel stocks, regional WA and outback NSW farmers were running out of diesel during the seeding window for winter crops. The NSW Farmers President said it plainly: “Right now, we’ve got farmers across the country who have run out, or are running out of fuel, while others are only a week or two away from empty.” The Victorian fruit-growing town of Robinvale ran completely dry — the town’s service station owner, in business 25 years, said he had never seen anything like it.

When fuel runs short at regional service stations, the consequences are immediate and tangible. Farmers cannot run tractors. Trucks cannot make deliveries. Emergency services cannot respond. The Royal Flying Doctor Service cannot fuel aircraft. Power generation in remote communities — much of which is diesel-backed — becomes contingent on rationing. The whole architecture of remote-and-regional Australian life rests on diesel arriving, on time, every day, from the eastern refineries via the eastern rail line and the eastern highway. When the line is cut, when the highway floods, when the diesel itself runs short upstream — that architecture starts to fail.

7A.4 The elevated answer

An elevated MMC corridor at 6–8 m above ground level does not flood. It does not buckle in 200-year rainfall events. It does not become inaccessible to repair crews because the access roads have washed out. It does not require weeks of remote heavy-equipment movement to restore. The line keeps running because the line is above the flood.

This is not a marginal infrastructure improvement. It is the difference between West Australian and Northern Territory households having reliable access to food, medicines, and fuel through the worst of the climate-driven weather Australia is now seeing every two to four years, or having three flood-week empty-shelf events per decade until something worse happens. Elevated freight infrastructure is not a luxury. It is the minimum standard for a country whose national supply chain runs through repeatedly-flooding outback country.

7B. When Freight Costs Crush Business — The Bottom Line

The other side of the diesel-and-line-cut crisis is what high fuel-driven freight costs are doing to Australian business. This is not abstract economic statistics. It is regional businesses closing every week, farmers leaving the land, trucking operators parking trucks they cannot afford to run, and small manufacturers losing the cost competition with imports because their freight bill alone exceeds their gross margin.

7B.1 Trucking businesses closing already

According to the Australian Trucking Association (ATA), one in twelve Australian trucking businesses closed in the twelve months to November 2025 — before the March 2026 fuel crisis began. The ATA reported that wholesale diesel prices have risen more than 67 % since the first week of March 2026, with diesel jumping from approximately A$130 per barrel to almost A$220 per barrel in days, and retail diesel up nearly 19 cents per litre in a single weekend.

Trucking businesses operate on tight margins. Fuel is typically the top operational cost, often 30 % of total operating costs. A 67 % fuel cost increase cannot be absorbed by carriers; it must be passed through. When customers’ contracts do not include fuel escalation clauses, the operator absorbs the loss, and the operator goes out of business. The National Road Transport Association (NRTA) chief executive Warren Clark warned in March 2026 that “many trucking businesses will struggle to pay their fuel bills when invoices arrive on April 21st”, with freight operators “parking trucks and laying off drivers because they can’t continue to absorb rocketing fuel costs”.

The Transport Workers’ Union national secretary Michael Kaine described the situation as “imminent risk of collapse” for businesses and “deadly pressure” for drivers. NRTA warned that “bananas at $15 a kilo” was the kind of consumer-price translation that would follow if the freight system was allowed to collapse on diesel cost alone.

7B.2 The farmer cost squeeze

For farmers, the diesel-and-freight squeeze hits twice. Once on the farm — tractors, harvesters, irrigation, pumping, on-farm transport — all of which run on diesel that has risen 67 % in two months. Again at the freight stage — getting produce from the farm gate to the silo, the abattoir, the processor, the port. National Farmers’ Federation president Hamish McIntyre warned in March 2026 that “in a matter of weeks we’ll start to see the costs flow through to the consumers on supermarket shelves”, with dairy hit first, then fruits, vegetables, and intensive animal industries.

For perishable producers — dairy farmers, fruit growers, seafood operators, fresh meat producers — the freight cost is often the difference between a profitable farm and an unviable one. Australian agriculture is already running on margins that have been squeezed by every input cost increase since 2020. Diesel-driven freight cost increases land on top of fertiliser cost increases, insurance increases, financing cost increases, and labour cost increases. Regional farms are closing. The transfer of farmland into corporate ownership and the hollowing-out of regional farming communities is in part a direct consequence of a freight system that makes regional agriculture cost-uncompetitive with imports.

7B.3 Regional manufacturing and food processing

The same logic applies to regional manufacturers, food processors, abattoirs, packing sheds, and small industrial operators outside the metropolitan areas. Their products must travel further than metropolitan competitors’ products to reach customers, on freight rates set by the same diesel-dependent road and rail system. When freight costs rise, their margin shrinks. When freight costs spike, they lose contracts to importers or to metropolitan-based competitors. When freight costs make their entire cost base structurally uncompetitive, they close.

Australia’s regional economy has been on the losing end of this dynamic for thirty years. Country towns that used to host abattoirs, dairies, packing sheds, sawmills and small manufacturers have progressively lost those businesses as urban consolidation and global imports out-competed them. The diesel-driven freight system is not the only cause of regional economic decline, but it is a substantial component — and it is one of the few causes that infrastructure investment can directly address.

7B.4 Electric freight changes the calculation

Electric freight on a continental MMC network changes the bottom-line cost structure for regional Australian business in three ways. First, the energy cost is lower: electric haul from renewable generation is structurally cheaper per tonne-kilometre than diesel haul, particularly at scale. Second, the energy cost is stable: electricity from a continental solar resource (MMA Memo 1) is not subject to Strait of Hormuz crises or Asian refinery export caps, so freight rates can be priced and contracted on a longer time horizon. Third, the speed is competitive: 250 km/h electric freight competes directly with road truck delivery times for perishable products on the continental routes, allowing regional producers to reach east-coast and Asian export markets within hours rather than days.

Each of these changes is a structural shift that disproportionately benefits regional Australian businesses. Lower energy cost reduces the freight bill. Stable energy cost removes the price-shock risk that has destroyed trucking businesses in 2026. Competitive speed opens premium markets to regional perishable producers that are currently locked out by transit time. The MMC continental network is not just decarbonisation infrastructure; it is regional economic infrastructure. It changes the bottom-line economics for the businesses that the diesel-dependent freight system has been killing for thirty years.

7C. How Much Freight, On Which Mode — The Scale of the Truck Problem

The argument so far has been about the consequences of the current system. This section grounds it in the volume realities. Australia’s domestic freight task is enormous, dominated by a small number of bulk export flows, but the non-bulk freight that runs daily Australian life is almost entirely on semi-trailers. The case for shifting freight from road to electric rail rests on understanding how much freight moves on which mode, and what that costs.

7C.1 The total domestic freight task — and why the headline numbers mislead

Australia’s total domestic freight task reached approximately 786 billion tonne-kilometres in 2024–25 — its highest level on record (BITRE, Australian Infrastructure and Transport Statistics Yearbook 2025). One tonne-kilometre is one tonne of freight moved one kilometre. The Australian freight task is one of the largest per-capita freight tasks of any developed economy, reflecting the country’s continental distances, export commodity profile, and dispersed population.

The headline split between modes appears to favour rail:

The headline number says rail moves more tonne-kilometres than road. That is true and it is also misleading. The next section explains why.

7C.2 The honest split — mining heavy-haul rail vs everything else

Australian rail freight is two completely different industries reported as one statistic. They serve different commodities, use different infrastructure, operate under different commercial logic, and have nothing to do with each other. Conflating them hides the actual freight failure.

Mining heavy-haul rail is not in competition with road. Iron ore from Pilbara to Port Hedland cannot move by truck — the tonnages are physically impossible to road-freight. A single Rio Tinto iron ore train carries approximately 25,000 tonnes, equivalent to roughly 700 B-triple road trains. The Pilbara moves on the order of 800 million tonnes of iron ore per year. The road equivalent does not exist and cannot exist. The miners built their own private rail because rail is the only physically possible way to move bulk minerals at continental scale. Mining heavy-haul rail is working exactly as designed, operates at world-class efficiency, and is not part of the freight failure conversation.

General freight rail is the category in actual competition with road, and it is losing. Strip the iron ore and coal volumes out of the rail figure, and Australia’s general-purpose rail freight is approximately 40–50 billion tonne-kilometres per year — less than 20 % of road freight, falling, on infrastructure that has not been seriously expanded in fifty years. This is the freight category that runs daily Australian life: the groceries that fill supermarket shelves, the manufactured goods that come from factories, the agricultural produce that moves from farms to processors and ports, the household goods that move from import terminals to retail distribution, the fuel that moves from refineries and import terminals to regional service stations. This is the category where rail’s share fell from 28 % to 2 % on the Melbourne–Sydney corridor over a generation, while the miners’ private heavy-haul kept being world-class on its own corridors.

The honest picture, with the two split out:

This is the structural picture. Mining heavy-haul rail handles the iron ore and coal export task because that is the only way to handle it. Coastal shipping handles bulk commodity flows because that is the only way to handle them. Air handles a small premium niche. Everything else — the general freight that runs households, retailers, farms, factories, and the regional economy — is on semis. There is no competing general-freight rail network at scale.

The MMC platform does not compete with mining heavy-haul rail. The Rio Tinto / BHP / Fortescue Pilbara network and the Queensland and NSW coal networks are private heavy-haul corridors serving single commodities, and they should continue to be. The MMC platform competes with the road freight system that currently moves the other 230 billion tonne-kilometres of Australia’s annual general freight task — the freight that should always have been on rail and never had a rail option built for it. That is the freight task this memo is about.

This is the structural reality behind the everyday experience that “semis keep Australia running”. Iron ore moves on rail because Rio Tinto, BHP and Fortescue built the rail. Coal moves on rail because the Queensland and NSW Governments built the rail. Everything else moves on the highway because no one has built rail for it. The Inland Rail project would have changed some of that for the Melbourne–Brisbane corridor. That project has now been cancelled at Narromine.

7C.3 Semi-trailers do almost all the long-haul road work

Of the 230 billion tonne-kilometres of road freight, more than 95 % of long-distance road freight is hauled on articulated trucks — that is, semi-trailers, B-doubles, B-triples and road trains (BITRE). Of the total road freight task, articulated trucks moved approximately 177.7 billion tonne-kilometres in 2020–21 — roughly 77 % of all road freight (Australian Logistics Council). Rigid trucks (the smaller trucks doing urban delivery and short-haul work) carry the remainder.

This is the practical answer to the question of who keeps Australia running. Semi-trailers do. Approximately 178 billion tonne-kilometres per year of semi-trailer haulage on diesel. Roughly half a billion tonne-kilometres every day. Every day. Across continental distances. On diesel that is 80–90 % imported, on a fuel stock of 30–37 days, on a 67 %-more-expensive-than-two-months-ago wholesale market, on a freight industry already losing one in twelve operators per year before the 2026 crisis.

For context: a single 1,500-metre freight train can carry the freight of approximately 100 semi-trailers (Australian Rail Track Corporation). The 178 billion tonne-kilometres of semi-trailer haulage that Australia performs each year is, on the equivalent rail measure, the work of roughly 1.78 billion semi-trailer-equivalents annually. That is the freight task that is currently on diesel-fuelled wheels rolling down highways — not because it is the most efficient way to move it, but because there is no continental electric rail alternative to carry it.

7C.4 The cost difference is structural, not marginal

The cost per tonne-kilometre comparison between road and rail in Australia is well documented and stark. BITRE-derived benchmarks: interstate road freight averages around 9 cents per net tonne-kilometre; rail averages around 4 cents. On the Perth–Melbourne corridor specifically, ARTC analysis put the rates at approximately 6.75 ¢/ntk for road versus 3.65 ¢/ntk for rail — road nearly double the rail cost.

The general goods supply chain benchmarking work submitted to the National Freight Data Hub goes further: road costs at ~$0.19 per tonne-kilometre, rail costs at ~$0.03 per tonne-kilometre — road approximately six times more expensive than rail for general goods over the routes where both are available. The cost differential varies by route, freight type and operator, but the structural finding is consistent: road freight is two to six times more expensive per tonne-kilometre than rail, depending on corridor and cargo.

This is the bottom-line argument back-grounded in the volume reality. Australia moves 178 billion tonne-kilometres on semis annually, paying somewhere in the range of 5–19 cents per tonne-kilometre, when the same work on continental rail would cost 3–9 cents per tonne-kilometre. The total Australian freight bill on long-haul road is in the tens of billions of dollars per year more expensive than it would be on continental rail. That is not an abstract macroeconomic statistic. It is real money being taken out of regional Australian business, regional Australian agriculture, and household budgets every year, to subsidise the diesel-dependent road freight system that exists because no one has built the rail alternative.

7C.5 Air freight is a rounding error — and a warning

Domestic air freight in Australia is approximately 337 million tonne-kilometres per year, projected to grow to 393 million by 2040 (BITRE 2019 update). This is less than 0.05 % of the total domestic freight task. Air freight is used only for the highest-value, most time-critical cargo — emergency medical supplies, urgent parts, time-sensitive premium perishables, business documents. It is also the most expensive mode by a wide margin (multiple dollars per tonne-kilometre, versus cents for road and rail).

Air freight is small because it is expensive. The lesson for the freight policy conversation is that even at extreme premium prices, Australian air freight volumes are constrained by what the customer can afford. The question of how much Australian premium agricultural production currently goes to overseas markets only because air freight is available, and how much more could go to overseas markets if continental electric rail provided a high-speed, lower-cost middle option, is a question this memo cannot answer in detail — but the existence of the gap is real. The MMC platform’s 250 km/h electric freight is not air-freight-fast, but it is fast enough to compete with air freight on cost for many time-sensitive cargo types, while remaining road-competitive on price for general goods. That intermediate position does not currently exist in Australia.

7C.6 The infrastructure footprint nobody builds

Australia has approximately 874,000 kilometres of total road network, of which approximately 381,185 kilometres are paved (Australian Logistics Council, ABS). The total rail network is approximately 32,868 route kilometres as at September 2020 — just under 4 % of the road network length.

This is the physical picture of Australian freight infrastructure choices over the last century. A road network 27 times the length of the rail network. A semi-trailer fleet doing more than 95 % of long-haul road work. A rail network whose general freight share has been falling for thirty years because we keep upgrading roads and not building new rail. The Inland Rail project, intended to add roughly 1,700 km of new freight rail, would have been the largest single addition to the Australian rail network in a generation. That project has now been cut in half.

The MMC continental network as set out in this memo would add approximately 17,400 kilometres of new tri-modal corridor to Australia’s infrastructure base. That is roughly half the length of the entire existing rail network — new, elevated, electric, multi-modal. Plus the Phase 0 corridor and spurs add another ~5,600 km. The full MMC network is a roughly doubling of Australian rail infrastructure, but built as multimodal corridor rather than single-purpose rail. It is the largest single addition to Australian transport infrastructure since the original interstate highway expansion of the 1960s.

The headline conclusion of this section: Australia’s general non-bulk freight task is overwhelmingly on diesel-fuelled semi-trailers, at a cost per tonne-kilometre that is roughly two to six times more expensive than rail would be, because rail does not exist on most of the corridors where freight needs to move. The MMC network does not just replace some semi-trailers with electric rail. It builds the rail infrastructure that should have been built progressively over the past forty years and was not. The catch-up is large. The case for catching up is urgent.

8. Phase by Phase — Continental Rollout

8.1 Phase 0 first

Phase 0 (Melbourne to Brisbane plus seven east-coast spurs) is delivered first because it is the most demand-rich, most engineering-resolvable, and most politically winnable phase. Phase 0 proves the platform, builds the sovereign manufacturing base, trains the workforce, and demonstrates the consortium delivery model. Every subsequent phase is faster and cheaper because Phase 0 has been built.

Phase 0 is the subject of MMA Memo 2. It delivers approximately 5,600 km of corridor (2,284 km spine plus 3,360 km of seven spurs). It connects every major east-coast Australian port and airport.

8.2 Phase 1 — the continental commitment

Phase 1 begins the continental rollout: SBC #1 Brisbane to Perth, SBC #2 Darwin to Adelaide, and Phase 1-1 Perth to Albany. Total Phase 1 distance: approximately 6,775 km.

Phase 1 is the moment the platform commits to continental Australia. SBC #1 replaces the Trans-Australian Railway as the east-west spine. SBC #2 replaces the Adelaide-Darwin Railway as the north-south spine. Both corridors run elevated, electric, and at 250 km/h freight / 600 km/h passenger. Both carry HVDC transmission integrating the central Australian Solar Regions with both coastal grids.

Phase 1 also lands the diesel-substitution argument. With SBC #1 and SBC #2 operational, the bulk of continental long-haul freight that currently moves by diesel road train or diesel rail can shift to electric MMC rail. The fuel security position changes structurally for the first time in thirty years.

8.3 Phase 2 — the inland and resource corridors

Phase 2 adds SBC #3 (inland north-south) and SBC #4 (trans-northern resource corridor). Approximately 5,416 km. These corridors complete the inland network and bring the Pilbara and the Bowen Basin onto the continental rail network as electric freight rather than diesel-haul heavy rail.

8.4 Phase 3 — the western and northern completion

Phase 3 adds SBC #5 (western coastal) and SBC #6 (long northern connector). Approximately 5,413 km. These corridors complete the western Australian and far-northern Australian network and provide the resilience paths through the continental system.

8.5 Total programme

The full MMC network: approximately 23,200 km of elevated tri-modal corridor across continental Australia. Built over a 25-year rolling delivery on a phased basis, each phase financing and proving the next. Sovereign Australian engineering, patent-protected, manufactured in sovereign Australian megafactories, operated under the Sovereign Build Corporation consortium structure.

This is not a megaproject. It is a continental infrastructure programme delivered over a generation, in modular phases, with each phase commercially financeable on its own merits. The closest international analogues are the US Interstate Highway System (delivered 1956–1992, 77,000 km), the Chinese High Speed Rail network (delivered 2008–present, 45,000 km operational), and the European TGV/ICE/AVE network (delivered 1981–present, 10,000 km+ operational). The MMC programme is in the same class of continental infrastructure investment as those programmes — smaller in total distance, larger in integrated functionality.

9. The Strategic Case

9.1 Fuel sovereignty

Australia’s 30-day diesel stockholding is a structural national security vulnerability. Australia cannot quickly replace the imported fuel that runs the country. The MMC continental network reduces structural diesel dependency by shifting long-haul freight from diesel road train and diesel rail to electric MMC freight powered by domestic renewable generation. The shift does not eliminate diesel dependency — first/last-mile vehicles, aviation, shipping, and some agricultural and mining equipment will remain diesel or hybrid — but it removes the long-haul freight stage from the diesel system entirely. Continental freight becomes powered by sovereign Australian renewable electricity rather than imported Middle Eastern crude.

9.2 Net zero

Australia’s 2050 net zero commitment is legally binding. Transport emissions are 19 % of national total. The dominant contributors within transport are road freight, aviation, and shipping. Electrification of road freight at continental scale requires either battery-electric trucks with infeasible charging and battery economics, or modal shift to electric rail. The MMC platform delivers the modal shift. Without modal shift, Australia’s transport-sector path to net zero is structurally infeasible.

9.3 Climate resilience

The Trans-Australian Railway has been cut by floods three times in four years. The Adelaide-Darwin line is similarly vulnerable. State-level highway and rail networks have been cut repeatedly by flooding across Queensland, NSW, and Victoria since 2022. As the climate continues to produce more concentrated rainfall events, ground-level continental rail and road infrastructure becomes more vulnerable, not less. Elevated MMC viaduct is the only continental infrastructure form that is structurally resilient to the climate trajectory.

9.4 Economic geography

The MMC continental network is the economic geography of Australia at last brought into modern integrated infrastructure. Every state capital, every major regional centre, every major port, every major airport, every mining province, every agricultural belt — all on one network. Regional Australia gains the transport spine it has lacked for sixty years. Capital cities gain integration with each other and with the regions. The Asian export economy gains an electrified continental rail backbone to support its growth.

9.5 Sovereign Australian industrial capability

The MMC platform is sovereign Australian engineering. The patents are filed in Australia. The manufacturing is in Australian megafactories. The construction workforce is Australian. The delivery consortium is Australian-anchored. The programme rebuilds Australian heavy industrial capability at continental scale, anchored in regional manufacturing centres (the SBC programme designs the first megafactory in the Hunter Valley, with subsequent megafactories distributed across regional Australia). This is the industrial sovereignty argument that the Australian political conversation has been searching for and not finding.

10. The Honest Caveats

This memo argues for a continental national infrastructure programme. It is honest about what the programme is not.

The MMC platform is pre-feasibility. The engineering is documented in the MMC patent family (seven patents, AU provisional filings 2026903869 through 2026904403) and in the MMC engineering memo series (multimodalcorridors.com). The economic modelling sits in the SBC Consortium Prospectus, currently in v22 and under review. Detailed engineering by chartered rail experts, HVDC vendors, and Australian construction primes is the next stage of work.

The continental phases (SBC #1 through SBC #6) are 10–25 year delivery programmes. They are not deliverable in a single electoral cycle. The argument is not that the country must commit to all phases at once; the argument is that Phase 0 must be funded and underway in this electoral cycle, and Phase 1 in the next, so that the platform is proven and the manufacturing base is built before the larger phases need to begin.

The programme faces real political and commercial obstacles. State governments compete for federal capital and infrastructure attention. Existing rail and road freight operators have legacy commercial positions to defend. Existing transmission utilities have grid plans that do not assume corridor-based rebuild. Indigenous land rights and environmental approval processes are substantive and rightly so — the corridor cannot be built over the heads of First Nations communities or in disregard of environmental sensitivities. Each of these constraints is real, deserves serious engagement, and is addressed substantively in the SBC documentation.

None of these constraints, on examination, defeats the underlying logic of the programme. They are the work of delivering the programme rather than reasons not to begin it.

11. Where to Next

• Read MMA Memo 2 — After Inland Rail: The East-Coast Plan for the Phase 0 case that precedes this memo. Phase 0 must be delivered before any continental phase becomes real.
• Read MMA Memo 1 — Solar Sizing for the SBC for the renewable electricity resource that the MMC corridors will carry as transmission and use as electric freight power.
• Read the MMC engineering memos at multimodalcorridors.com for the technical detail behind the corridor architecture, station/ramp design, HVDC transmission, and precast manufacturing system.
• Read the SBC Consortium Prospectus (currently v22, in pre-publication review) for the economic and financing structure of the continental programme.
• Engage politically. The Modern Movement Australia campaign is building toward the 2027 federal election. The case for continental electric freight as the answer to fuel sovereignty, net zero, and climate resilience needs to be made in the political conversation.
• Engage commercially. Australian mining, agriculture, manufacturing, energy and freight industries that would use the continental network have direct commercial interests in seeing it delivered. The SBC consortium structure is designed to enable their co-investment.
• Engage with Indigenous communities and environmental stakeholders. Continental infrastructure of this scale must be built in partnership with First Nations communities whose country it crosses, and within environmental constraints that protect the ecosystems it traverses. These engagements are not constraints on delivery; they are part of delivery.
• Engage publicly. Share this memo. Discuss it. Disagree with it. Improve it. Australia’s continental infrastructure decisions over the next decade will be made through public conversation, not by reports alone.
