Defence Through Nation Building

A continental nation in a global economy defends itself best by building itself. This memo argues for repositioning the AUKUS programme: redirecting its funding, industrial base, and engineering expertise away from distant power projection and into a defensive sovereignty posture — unmanned coastal defence, Sovereign Defence Manufacturing under the SBC umbrella, and Asia-Pacific infrastructure interconnectors that bind the region in shared prosperity rather than divide it.

1. The argument in one paragraph

Australia's geography — an island continent the size of mainland United States, a coastline of 35,000 kilometres, an Exclusive Economic Zone of more than 8 million square kilometres — makes traditional forward defence at continental scale either prohibitively expensive or strategically incoherent. Australia's economic position — deeply integrated into the Asian community of nations, on which around two-thirds of Australia's total trade depends — makes any defence policy built on the assumption of decoupling from major regional trading partners materially harmful to the prosperity it is meant to protect. The synthesis these two facts point to is simple: Australia's smartest defence policy is to build the nation it intends to defend, and to build it in a way that makes the country valuable to the region rather than threatening to it.

The AUKUS programme is the obvious vehicle. The skills, the funding commitments, the shipbuilding and engineering base, the workforce, the supplier relationships, the security clearances — none of this needs to be cancelled. What it needs is repositioning. Away from a small fleet of long-range nuclear submarines designed for distant power projection, and toward a defensive sovereignty posture: mass-produced unmanned underwater vehicles for coastal and seabed defence, specialised cable-laying and pipeline vessels, Sovereign Defence Manufacturing under the SBC umbrella that supplies cables and pipes and high-voltage infrastructure and composite materials onshore in Australia, and continental connector projects that make Australia indispensable to a regional infrastructure web rather than peripheral to it.

This is not a pacifist argument. It is the opposite. It says: a continental nation that manufactures what it builds, that can feed and power and move itself without imported components, and that is the central node in a regional infrastructure network of energy, water, and data is harder to coerce and isolate than one that depends on eight submarines arriving in the 2040s. Internal strength is the durable form of deterrence. This memo sets out how the AUKUS repositioning could deliver it.

2. Why traditional forward defence is the wrong frame for Australia

The original case for AUKUS Pillar 1 — eight Australian nuclear-powered submarines (SSNs) from the 2040s, rotational US and UK basing, perhaps 20,000 jobs across the build programme — rested on a specific theory of Australian security: that Australia's shipping lanes were the critical asset to defend, that submarines projecting force forward into the South China Sea and the Indo-Pacific archipelago were the right tool, and that the United Kingdom and the United States were the right partners to build them with. Each of these assumptions deserves a hard second look.

The shipping-lanes premise is wrong on the facts. Australia's strategic dependence on seaborne trade is real — around 99% of Australia's import and export tonnage moves by sea, through chokepoints thousands of kilometres from the Australian coast. The proposition behind AUKUS Pillar 1 is that an Australian submarine fleet can meaningfully contribute to keeping these chokepoints open. The events of the last few years make this proposition very difficult to sustain.

The Red Sea case is the clearest example. From late 2023, Houthi forces in Yemen — a non-state actor operating consumer-grade drones, cheap anti-ship missiles, and modest sea-borne unmanned vessels — have effectively closed the Bab el-Mandeb / Red Sea / Suez Canal route to a large share of global shipping. Container traffic through the Red Sea fell by approximately 60–70% within months, with major carriers rerouting around the Cape of Good Hope at an additional 10–14 days and several million dollars per voyage. This disruption has persisted despite sustained naval intervention by the United States, the United Kingdom, the European Union, and a multinational coalition — the most concentrated deployment of high-end Western naval power in a decade. The coalition has not reopened the route. The lane remains contested by a non-state actor with a hardware budget rounding to a rounding error of the AUKUS programme cost.

The Strait of Hormuz case is a parallel story at lower intensity: a chokepoint perpetually exposed to disruption by relatively cheap asymmetric threats, persistently patrolled by the world's most powerful navies, never decisively secured. Approximately 20% of global oil and a significant share of LNG passes through the strait. Iran's capacity to disrupt it is well-documented and well-resourced. The combined US Fifth Fleet, allied vessels, and bilateral security commitments have not removed the threat — they have managed it, at considerable cost, on terms that include accepting that the strait can be closed temporarily by the adversary's choice.

These are not academic cases. They are real-world demonstrations, happening now, that even the world's most powerful navies cannot reliably keep open the shipping lanes Australia depends on. If the combined US, UK, EU, and allied forces cannot reopen the Red Sea against Houthi pressure at relatively short range from their nearest bases, the proposition that eight Australian submarines based 12,000 kilometres away in Western Australia, arriving over the course of two decades from the 2040s, will meaningfully contribute to shipping-lane security is not a serious one. Australia cannot control its own shipping lanes, and no realistic Australian naval programme can change that. The lanes are kept open, when they are kept open, by a combination of commercial routing, insurance markets, fuel-price absorption, and the limited capacity of the major naval powers. None of those instruments are improved by Australian SSNs.

The implication is uncomfortable but useful. If shipping-lane defence is not achievable through the AUKUS submarine programme, the AUKUS submarine programme is not solving the problem it is being sold as solving. The strategic question therefore becomes how to reduce Australia's exposure to disruption of shipping lanes Australia cannot control — that is, how to reduce Australia's structural dependence on imported diesel, imported electronics, imported pharmaceuticals, imported industrial components, and imported manufactured goods. That is a sovereignty question, not a submarine question, and it is the question this memo is fundamentally about.

The scale problem. Australia's coastline is 35,000 km. Its EEZ is more than 8 million km². Even a fleet of dozens of crewed surface combatants and submarines cannot be everywhere at once. Genuine continental coverage requires either an unaffordably large force or a fundamentally different posture: mass unmanned systems that can be deployed cheaply at scale, persistent, and difficult to defeat through attrition. The Ukrainian use of unmanned surface and subsurface vessels in the Black Sea is the template — relatively low-cost platforms, produced in volume, delivering strategic effect against far more expensive crewed adversaries.

The supply-chain exposure problem. Even if eight nuclear submarines were the right answer to the question of Australian coastal defence (and they are not), the programme as currently structured leaves Australia critically dependent on foreign supply chains for nuclear propulsion technology, specialised steel, advanced electronics, and the maintenance ecosystem the boats will require for their fifty-year service lives. Sovereign capability that depends on foreign suppliers for its most critical components is not sovereign capability. It is licensed capability with extra steps.

None of this is an argument that Australia should not have submarines, or should not have AUKUS. It is an argument that the structure of AUKUS — what it builds, where, with what, and for what purpose — is the wrong fit for the strategic situation Australia is actually in, and that the right move is to reposition rather than to either continue or cancel.

3. The repositioning — what AUKUS can become

AUKUS has already built an enormous amount of value that nobody should walk away from: the workforce, the funding commitments, the shipyard infrastructure, the supplier relationships, the security partnerships with the United Kingdom and the United States. What needs to change is the output of all this capacity.

3.1 From crewed submarines to mass unmanned systems

The most important repositioning is the shift from a small fleet of large crewed nuclear submarines to a large fleet of small-to-medium unmanned underwater vehicles. The technology is already substantially proven — AUKUS Pillar 2 already covers autonomous systems, and Anduril's Ghost Shark, developed in partnership with the RAN, is the working example of the class. The proposition is to scale this dramatically: mass-produce unmanned coastal and seabed defence platforms in Australia, with Australian-manufactured components, and field them in numbers measured in hundreds rather than in eights. The skills built up in the submarine programme — pressure-hull engineering, naval architecture, underwater acoustics, autonomous systems integration — map directly onto this new mission. The difference is unit cost, production volume, and the asymmetry of the threat the adversary faces. A coastline patrolled by hundreds of persistent unmanned platforms is a much harder target than a coastline patrolled by eight crewed ones.

3.2 From submarine hulls to dual-use industrial vessels

Shipbuilding capacity that is not building submarines does not have to sit idle. Australia is a country that will need, over the next two decades, a substantial fleet of cable-laying vessels, pipeline vessels, and offshore construction ships to install the subsea infrastructure that connects the SBC continental network to the Asia-Pacific region and to support the substantial offshore wind and gas resource that surrounds the continent. These vessels are dual-use by nature: a cable-laying ship is also a strategic asset in wartime. AUKUS shipyards can build them. The skills transfer is direct. The output is commercially valuable in peacetime and strategically valuable in any future contingency.

3.3 From import-dependent assembly to Sovereign Defence Manufacturing under the SBC umbrella

The most consequential repositioning is the one that touches the rest of the platform. Sovereign Defence Manufacturing — a manufacturing programme under the Sovereign Build Corporation umbrella, dimensioned to supply both the SBC's civilian infrastructure and the repositioned AUKUS defence base — produces onshore in Australia the materials and components that both programmes require: transmission cables, steel pipes, high-voltage infrastructure, composite materials, specialised electronics, naval architecture components, unmanned-systems sub-assemblies. The programme is dimensioned around dual-use demand: SBC needs ten million tonnes of steel pipe for water and gas pipelines; the unmanned-systems programme needs pressure-hull steel for hundreds of UUVs; both demand bases can be served by the same Australian steel mill running at industrial scale, which would not be commercially viable for either demand base alone. The same logic applies to transmission cables, to composite manufacturing, to high-voltage substation gear. The SBC's civilian infrastructure demand and the repositioned defence demand together justify the sovereign manufacturing base that neither could justify on its own.

The Sovereign Manufacturing Multiplier memo (MMA Memo 6) sets out the underlying argument: that the SBC programme creates the demand floor for re-industrialising Australia in materials that the country currently imports. The defence repositioning doubles the demand floor and turns a strong industrial argument into a structural one.

4. Why national sufficiency is the right primary defence policy

Beyond the AUKUS-specific repositioning, the broader strategic claim of this memo is that Australia's primary defence policy should be nation building and national sufficiency — the deliberate cultivation of a continent that can feed, power, move, and manufacture for itself without depending on imported components for the things that matter.

4.1 The interdependence argument

Australia operates in a deeply interconnected global economy. Disruptions on the other side of the world — in the Red Sea, in the Strait of Hormuz, in Eastern Europe — ripple through Australian fuel prices, freight costs, food prices, and inflation within weeks. Wars destroy prosperity on every side. Economic interdependence has historically promoted peace far more reliably than military deterrence has: trading nations with deep mutual stakes rarely fight each other, and when they do, both sides lose. The implication for a country in Australia's position is that maintaining and deepening the trade relationships that make Australia prosperous is, in itself, a defence policy — perhaps the most important one. The MMA platform does not treat trade as in tension with security. It treats trade as one of the foundations of security.

Australia's trade is concentrated in the Asian community of nations to an extent that has no historical parallel. Roughly two-thirds of Australia's total two-way trade is with Asian partners; iron ore, LNG, coal, education, agriculture, and services together form the largest contributor to Australia's current account, to GST receipts, to state-government royalty income, and to a large share of regional Australian employment [1]. A defence policy that treats those relationships as problems to be managed adversarially is a defence policy that materially impoverishes the country it claims to defend. The MMA position is that constructive engagement with the Asian community of nations — alongside the existing relationships with the European Union, the United States, and the United Kingdom — is part of the defence policy, not a distraction from it.

4.2 The sufficiency argument

Inside that interdependent global frame, what makes a country harder to coerce is its internal strength — the things it does not need to import, the things it can do for itself if the trading system temporarily fails. For Australia, the list of strategic dependencies is uncomfortable: refined liquid fuels (around 90% imported, with roughly four weeks of operational reserve under stress), pharmaceuticals (more than 90% imported), critical industrial inputs (cables, transformers, steel pipe, electronics, ammunition components), and a substantial share of the consumer-electronics supply chain. These are dependencies that no submarine fleet can remediate. They can only be remediated by building the manufacturing base at home. Sovereign manufacturing is sovereign defence, expressed through the medium of the industrial base rather than the medium of the rifle range.

The SBC platform is dimensioned around this principle. The Phase 0 corridor delivers freight independence from imported diesel for a substantial share of national tonne-kilometres. The Alice Hub delivers continental water and energy storage. The agrivoltaic programme delivers continental food and electricity production simultaneously across the same hectares. Sovereign Defence Manufacturing under the SBC umbrella delivers the materials base for both the civilian programme and the repositioned defence programme. The continent that emerges from this build sequence is a continent measurably harder to coerce than the one we live in today.

5. Transport fuel sovereignty — the sharpest case

The general argument of §4 has a sharpest case. Australia's transport-fuel position concentrates every weakness the sufficiency frame identifies into a single, currently unfolding example. The pieces:

• Approximately 90% of Australia's refined fuel is imported [2]. Of the eight major refineries operating in Australia in 2005, only two remain — Viva Energy's Geelong refinery and Ampol's Lytton refinery in Brisbane — together producing approximately 20% of national fuel demand and skewed toward gasoline rather than the more critical diesel.
• Australia is the only IEA member country that does not hold the 90-day strategic fuel reserve required by the agreement [3]. The country has failed to meet this requirement since 2012; the domestic target has been progressively downgraded; current working reserves run at approximately 30–40 days of normal demand depending on the fuel type, well below the IEA benchmark.
• The imported fuels arrive almost exclusively by sea, in tanker vessels that are foreign-owned and foreign-crewed. Australia has no sovereign control over the shipping schedules, the routes, the pricing terms, or the priorities applied to its cargoes [2].
• The supply chain runs through every chokepoint discussed in §2. Refining capacity sits primarily in South Korea, Singapore, Japan, Malaysia, India, and China. Those refineries source crude through the Strait of Hormuz, the Malacca Strait, and the Indonesian archipelago. The lanes Australia cannot defend, supplied by refineries Australia does not own, by ships Australia does not crew, are the lanes Australia's transport fuels travel on.

This is not a theoretical risk. As this memo is being written in May 2026, Australia is in the middle of a real-world demonstration of the entire chain. The Iranian closure of the Strait of Hormuz that began in late February 2026 has reduced Hormuz traffic to near zero; South Korea, Thailand, and China have imposed export restrictions on refined products; six tankers carrying refined products bound for Australia were cancelled or deferred in late March; for the first time in decades, Australia is sourcing emergency cargoes from the United States Gulf Coast at 55–60 day transit and approximately four times the per-barrel freight cost of the lost Asian routes [3, 4]. Forty-three tankers are reported in transit toward Australian ports under the current crisis [4]; whether all of them arrive, with what cargo, on what schedule, and at what price, is determined offshore by parties Australia has no jurisdiction over.

The question this raises for the AUKUS programme is brutal and exact. The eight nuclear submarines arriving from the 2040s, and the ten or so other major surface combatants in the current Royal Australian Navy, cannot defend the sixty-plus tanker movements per month that the Australian economy currently depends on. They cannot escort them through Hormuz. They cannot keep Singapore refining capacity available to Australian customers when Singapore prioritises its own demand. They cannot prevent South Korean export curbs. They cannot accelerate a US Gulf Coast cargo on a 60-day passage. They are, by capability and by geography, the wrong tool for the actual problem. No achievable Australian navy — not eight submarines, not eighty, not a force five times the current ADF total spend — can put a defended military escort on every refined-product tanker travelling from East Asian and Middle Eastern refineries to Australian ports through chokepoints thousands of kilometres from Australian bases. The arithmetic does not allow it.

The implication for Australian defence policy is correspondingly precise. If the country cannot defend the shipping lanes the fuels arrive on, the strategic answer is to reduce or eliminate the dependency on those shipping lanes. Not by buying more ships. By doing two things in parallel: holding a meaningful reserve as a bridge, and replacing the demand itself with sovereign, domestically-produced and -delivered transport energy.

5.1 The bridge — the 90-day reserve

The MMA platform already calls for Australia to meet its IEA-required 90-day strategic fuel reserve, funded as a defence asset. This memo reinforces that position: fuel sovereignty is a defence question, the reserve is a defence asset, and the funding sits inside the 3% of GDP defence allocation rather than in the general budget. The reserve is a bridge while the substantive replacement programme is built. It is not the solution; it is what carries the country across to the solution.

5.2 The replacement — sovereign domestic transport energy

The substantive answer is the SBC platform itself. The programme is, when viewed through the defence-sovereignty lens rather than the infrastructure lens, a deliberate progressive replacement of the imported-liquid-fuel demand base with sovereign domestic electricity:

• Electrified freight on the SBC corridor (MMA Memo 3): the Phase 0 corridor and its continental extensions progressively move the bulk of national tonne-kilometres off imported diesel onto grid-supplied electric rail. The carbon argument is obvious; the sovereignty argument is more important. Every tonne-kilometre that moves on an electrified MMC corridor is a tonne-kilometre that no longer requires an imported diesel cargo to deliver.
• Maglev passenger transport on the SBC continental routes (MMA Memo 17): removes the dominant share of domestic aviation jet-fuel demand on the routes the maglev serves. Jet fuel is the segment of liquid-fuel imports with the deepest current shortage exposure.
• Sovereign electricity supply: the corridor and its hubs (MMA Memo 5) deliver continental-scale renewable generation, storage, and transmission — the electricity supply that the electrified transport modes draw on, sourced from Australian sun, wind, and pumped hydro on Australian land. No imports required.
• Agricultural fuel substitution: the 13.4 million-hectare agrivoltaic programme on Australia's arid country produces electricity at scale alongside its agricultural output. The transition path for agricultural diesel demand — through grid charging of electric farm machinery, through biodiesel made from on-station biomass, through green ammonia produced from agrivoltaic-supplied electricity, or through some mix of those routes — is the slowest of the four replacement tracks but is exactly the kind of programme the Sovereign Defence Manufacturing base described in §3.3 is dimensioned to support.

The combined effect is that Australia's transport-fuel demand base shrinks progressively over the SBC build-out, from the current ~1.1 million barrels per day of liquid-fuel demand toward a residual demand met by the two remaining domestic refineries plus a maintained strategic reserve. The shipping-lane dependency does not need to be defended. It needs to be retired. That is what sovereign defence policy looks like for a continental nation in a global economy.

6. Australia in the Asian community of nations

The internal-strength argument of §4 and §5 has a corresponding external argument. The deeper claim — and the one that makes the rest of this memo coherent — is about where Australia chooses to sit in the region it occupies. The MMA position is that Australia's strategic future lies in becoming part of the Asian community of nations: economically integrated, infrastructurally connected, politically engaged, alongside its neighbours.

6.1 The political frame — why integration is the rational choice

The world economy of the 2020s is structurally different from the one in which earlier strategic doctrines were formed. The decisive shift is the depth of global economic interdependence. In the nineteenth and early twentieth centuries, wars sometimes paid for the victor — territory acquired, resources extracted, reparations imposed. That calculus no longer holds. In a globalised economy where production runs on continental supply chains, trade balances are measured in the trillions, and the financial system propagates shocks across borders in hours, major-power conflict destroys prosperity for every side simultaneously. The aggressor suffers. The defender suffers. The neighbours suffer. The notional winner suffers. Wars are now collective economic catastrophes, and the prosperity destroyed often takes a generation to rebuild even for parties who never fired a shot.

This is not a moral observation. It is an economic one, and it leads to a strategic conclusion. In a deeply interdependent global economy, peaceful integration is not just preferable. It is the only economically rational option for nations that intend to be prosperous. The instruments of peace — trade, infrastructure, shared institutions, mutual investment, regular diplomatic engagement — are not soft alternatives to defence. They are the substantive mechanisms by which conflict is made unattractive enough that rational actors choose other paths. Military deterrence still matters at the margin. But economic interdependence does the structural work.

The clearest working example is the European Union. Two world wars in thirty years across the same set of borders, fought between the same set of nations — followed by a deliberate post-1945 project to bind those nations together through coal, steel, energy, trade, monetary policy, and shared institutions until intra-European war became structurally impossible. The EU did not eliminate disagreement between France and Germany, between northern and southern members, between long-standing and newer members. It eliminated the option of resolving those disagreements through war. Eighty years on, the result is the longest period of peace on the European continent in recorded history, achieved not through dominance by any single power but through the deliberate construction of interdependence among many.

The argument of this memo is that Australia's strategic situation in the 2020s and 2030s rhymes with Europe's strategic situation in the 1950s. A region that has known major-power conflict in living memory. A set of nations whose economic fates are already deeply intertwined whether or not the political relationships acknowledge it. A geography in which any major conflict would be ruinous for every participant including the notional winners. The historical answer Europe found — deliberate, infrastructural, economic integration deep enough to make war structurally unaffordable — is the answer that Australia and the Asian community of nations should be working toward in their own form, suited to their own geography, on their own timetable.

The institutional starting point for Australia is ASEAN, where Australia is already a dialogue partner with an established record of engagement. ASEAN is the existing regional institution; it is the working architecture through which deeper integration with Southeast Asia, and through Southeast Asia with the broader Asian community, is most naturally built. ASEAN is not the EU; it operates on consensus, with strong respect for sovereignty, and without the supranational legal framework the EU has developed. That is appropriate for the region. The model is not to import European institutions into Asia. The model is to deepen the Asian institutional architecture that already exists, in directions that bind member nations together through shared infrastructure, shared prosperity, and shared interest in regional stability.

The argument is necessarily inclusive. A regional community of nations is not built by excluding the largest neighbours; it is built by drawing every party that shares the region into shared infrastructure, shared institutions, and shared interest in regional stability. The choice is not between integration and selective integration with preferred parties. It is between meaningful regional integration on the European-Union pattern, or no meaningful regional integration at all and a continuing drift toward the kind of strategic bifurcation that makes the next major-power war more rather than less likely. The MMA position is that the inclusive path is the one that protects Australian prosperity and Australian security. The exclusive path is the one that puts both at risk.

None of this means that Australia abandons its existing alliances. The relationships with the United States, the United Kingdom, Japan, South Korea, and India remain valuable and should be maintained. What changes is the strategic centre of gravity. Australia stops thinking of itself as a Western outpost in Asia and starts thinking of itself as part of Asia — and as a uniter within it. Australia's geography, political stability, rule of law, resource endowment, and existing partnerships across both Western and Asian institutions position it uniquely to act as a bridge-builder and convener within the regional community: a country trusted across multiple alignments, with the diplomatic and infrastructural means to host shared institutions, and the strategic interest in seeing them succeed. Few nations in the region are positioned to play this role. The MMA position is that Australia should claim it. A country whose prosperity, security, and future lie in deeper engagement with its neighbours — and in actively helping the region bind itself together — is a country acting in its own interest and in the region's simultaneously. That is a substantial reframing. It is also, on the structural facts of where Australia is, what it trades, who it sells to and buys from, and what kind of conflict it could not afford, the reframing the facts already demand.

6.2 The infrastructure mechanism — how the integration is delivered

Strategic intent without delivery mechanism is rhetoric. The integration described in §6.1 is delivered through the kind of shared infrastructure that the SBC programme is uniquely positioned to build. Australia's geography makes it the natural regional supplier of energy, water, food, data, and critical minerals to a region of around 4 billion people, many of which are resource-constrained. The MMA platform translates this into specific infrastructure:

• Continental green-energy export via subsea HVDC cable to Indonesia, Singapore, and beyond — the precedent has already been established by SunCable and its successors. Each cable laid is a strand of regional interdependence; each MWh delivered is a commercial relationship that compounds over decades.
• Subsea AI compute interconnectors linking Australian data centres — powered by the same renewable energy and cooled by the same desert geothermal capacity discussed in MMA Memo 8 — to East Asian and South Asian compute demand.
• Shared water and gas pipelines within the Australian continent and potentially extending to selected regional partners; a regional fibre-optic backbone that ties the Australian network into a broader Indo-Pacific data grid.
• Critical minerals supply processed and refined in Australia under Sovereign Defence Manufacturing rather than exported as raw concentrate, supplied to regional partners on long-duration contracts that align Australian and partner industrial planning over multi-decade horizons.

The pattern across all four is the same. Each infrastructure link is commercial in form and strategic in effect: a relationship that delivers value to Australia and to the partner every day it operates, and which therefore makes conflict between Australia and that partner increasingly unattractive on every passing day. This is the EU mechanism, expressed through the assets that Australia and its Asian neighbours actually need from one another.

The vessels that lay these cables and pipelines are exactly the ones the repositioned AUKUS shipyards can build (§3.2). The materials that go into them — cable, conductor, steel pipe, control gear — are exactly the ones Sovereign Defence Manufacturing under the SBC umbrella can produce (§3.3). The crews that operate them are exactly the workforce the existing AUKUS programme is training. The defence reposition, the manufacturing programme, and the regional integration strategy are not three separate ideas. They are the same programme, viewed from three different angles — and each angle reinforces the other two.

7. Why this works for Australia specifically

Few nations can credibly aim for high levels of national sufficiency. Most are too small, too resource-poor, or too geographically constrained to manufacture and energise themselves. Australia is the rare exception. The combination of continental scale, resource endowment, political stability, and existing technical workforce makes the national-sufficiency programme uniquely achievable here.

The economic return is significant. The SBC programme alone is estimated to generate several hundred thousand direct jobs across the build phase, with the operating phase supporting a comparable number indefinitely. Sovereign Defence Manufacturing adds tens of thousands more in regional and industrial centres — Wagga, Whyalla, Gladstone, Geelong, Townsville, Mackay, the Latrobe Valley — with substantial regional concentration. Asia-Pacific connector projects add a third tier of export-revenue jobs, particularly in northern Australia, Western Australia, and the Northern Territory. The continent that emerges is more populated, more industrialised, more energy-rich, and substantially more economically diversified than the one we are running today.

The strategic return is comparable. A continent that manufactures its own steel pipe, lays its own cables, builds its own naval architecture, produces its own pharmaceuticals, refines its own transport fuels, generates surplus electricity, exports surplus water and surplus food, and sits at the heart of a regional energy and data grid is not a continent that needs to choose between security and prosperity. It is a continent where the two reinforce one another.

8. What this looks like as policy

The MMA position is that Australian defence policy should be reorganised around the following pillars, in roughly this order of priority:

1. Australia as uniter in the Asian community of nations. Active diplomatic posture across the region, with explicit emphasis on the trading relationships that materially support Australian prosperity and on the institution-building that deepens regional integration on the European-Union pattern. Australia as builder, connector, and convener — not as a forward base for any particular power bloc, and not as a passive participant either.
2. Repositioned AUKUS. Retain the workforce, the funding, the shipyards, the partnerships, the security clearances. Redirect the output: from eight crewed nuclear submarines to several hundred unmanned coastal-defence platforms, plus a fleet of cable-laying and pipeline vessels, plus the Sovereign Defence Manufacturing base that supplies both. Targeted at 3% of GDP on defence overall — the figure already in the MMA platform — but with the spend allocated to durable national capability rather than to a single high-cost platform class.
3. Sovereign Defence Manufacturing under the SBC umbrella. An industrial programme dimensioned around the combined demand from SBC civilian infrastructure and the repositioned defence base. Cables, pipes, composites, electronics, naval architecture components, ammunition, pharmaceuticals, refined fuels. The list is set by the dependencies the country cannot afford to maintain.
4. The 90-day fuel reserve. Already in the MMA platform. Held as a transition policy while electrified freight on the SBC corridor progressively reduces national diesel demand. Funded out of the repositioned defence allocation, since fuel sovereignty is a defence question.
5. Asia-Pacific infrastructure connectors. HVDC, fibre, water, gas. Subsea where required. Built by Australian shipyards, with Australian-manufactured cable and pipe, crewed by Australian sailors. Each connector deepens the regional interdependence that is itself a deterrent against any single party choosing conflict.
6. The 3-sphere drone capability and the Ghost Shark line. Already on the MMA platform. The unmanned-systems mass production discussed in §3.1 sits within this framework, scaled substantially upward from current planning.

None of this requires Australia to abandon its alliances. The United States and the United Kingdom remain natural partners on technology, on training, on intelligence, on naval architecture. The shift is in what the alliance produces. A repositioned AUKUS that delivers an Australian-built unmanned coastal-defence fleet, an Australian sovereign manufacturing base, and a regional connector network is a stronger alliance contribution than a small number of submarines purchased from American and British supply chains and arriving in the second half of the century.

9. Honest caveats

This memo is a strategic possibilities paper, not a defence white paper. Several questions it does not attempt to answer in full:

Treaty implications. AUKUS is structured as a trilateral partnership with specific commitments. A repositioning of the kind described here would need to be negotiated with the United States and the United Kingdom, not declared unilaterally. The argument of this memo is that the case for repositioning is strong enough that the negotiation is worth having, not that the negotiation would be simple or quick. A useful starting frame is that both partners would benefit from a more capable, more industrial, more self-reliant Australia, and that the existing AUKUS workstreams on autonomous systems (Pillar 2) provide the natural vehicle for the shift.

Submarine question. The memo does not argue that Australia should have no submarines. It argues that the case for eight large crewed nuclear submarines from the 2040s is weak. A smaller capability based around conventional submarines acquired from established partners (Japan, South Korea, France, Germany have credible options) or around long-endurance large unmanned undersea vehicles is plausibly part of the repositioned posture. The detailed mix is a question for the strategic review the memo calls for.

Workforce transition. The 20,000 jobs associated with the AUKUS programme are real and politically important. The argument of this memo is that those jobs are preserved and grown by the reposition — into unmanned-systems production, cable-laying vessel construction, and Sovereign Defence Manufacturing — not that they are lost. The transition planning matters and would need to be done carefully.

Threat environment. The argument assumes that the dominant defence challenge for Australia over the next thirty years is coastal and EEZ protection, sovereign supply chains, and regional stability — not a major-power war fought at distance. This is a defensible reading of the strategic situation, but not the only one. A reader who believes the dominant challenge is forward power projection in the South China Sea will reach different conclusions.

The cost figure. The memo does not produce a detailed comparative budget. The MMA platform has 3% of GDP — approximately $90 billion per year in 2026 dollars — allocated to defence overall. The repositioning argued for here fits inside that envelope; the question is allocation across the pillars, not total spend.

10. The bottom line

Australia does not need to choose between security and prosperity, and it does not need to choose between alliance partnership and trading partnership. What it needs to do is reposition the largest single capital programme it currently has — AUKUS — so that the funding, the workforce, and the industrial base produce internal national strength rather than imported external projection.

A continental nation that manufactures its own materials, builds its own naval architecture, powers itself with surplus to export, feeds itself, refines its own fuels, lays its own cables, sits at the centre of a regional infrastructure network of energy and data, and plays an active role as a uniter and bridge-builder within the Asian community of nations is harder to coerce, harder to isolate, and a more valuable ally than the one we have today. It is also a richer, more diversified, more regionally balanced country — a continent that works for the people who live across it, not just for the cities on its eastern fringe.

The MMA position is that this is the right defence posture for Australia. The repositioned AUKUS programme is the vehicle. Sovereign Defence Manufacturing under the SBC umbrella is the industrial expression. National sufficiency is the strategy. The time to reposition, manufacture, and build is now.

11. Next steps

• Public call for a strategic review of AUKUS with explicit terms of reference covering: reposition options, unmanned-systems scaling, Sovereign Defence Manufacturing scope, and Asia-Pacific connector programme.
• Legislate the Sovereign Build Corporation with an explicit Sovereign Defence Manufacturing division integrated under the SBC umbrella, dimensioned around the combined civilian-and-defence demand floor.
• Begin diplomatic engagement with the United States, the United Kingdom, and key regional partners (Japan, South Korea, Indonesia, Singapore, ASEAN, India) on the repositioning, framed as an alliance contribution rather than a unilateral pivot.
• Commence detailed planning for the unmanned coastal defence fleet, the dual-use shipbuilding programme, and the regional connector projects, with a target of demonstrating capability within the first term of an MMP-led government.
• Future MMA memos in this series will cover specific topics in depth, including: Sovereign Defence Manufacturing — Scope and Sequencing; The Unmanned Coastal Defence Fleet — Production Architecture; Asia-Pacific Energy Interconnectors — The SBC Export Build-Out; and The 90-Day Fuel Reserve as a Defence Asset. Cross-links to be added as those memos are drafted.

DFAT trade composition data show that Australia's top ten two-way trading partners are dominated by Asian economies, with the combined share of two-way trade with Asian partners running at approximately two-thirds of total Australian trade across the 2023–2025 period. Year-to-year figures vary; the "two-thirds" figure used in this memo is a working approximation consistent with DFAT-reported totals.
