Electric heavy-haul rail replacing diesel B-doubles. Every commercial port on one network. Coastal corridors freed of freight pressure.
Australia moves its freight on diesel trucks because it has never built the alternative. Rail's share of the freight task has fallen from about 28 per cent to 2 per cent over a generation, the northern half of Inland Rail was cancelled in May 2026, and the single lines to Perth and Darwin have been cut by floods three times in four years. The fuel that carries all of it is about 90 per cent imported, with roughly 30 days held onshore.
The MMA answer is a continental electrified freight network built on the corridor — three heavy-haul tracks on the same elevated structure that carries the transmission powering them, reaching every major commercial port in the country: Newcastle, Brisbane, Sydney, Melbourne, Adelaide, Fremantle, Darwin, Port Hedland, Gladstone, Mackay and Eden. Because the corridor is elevated and flood-proof, and because it is a network rather than a single line, a cut in one place no longer severs a state.
Three things follow. It is cheaper: rail is several times more energy-efficient than road per tonne-kilometre before electrification, and afterwards it runs on domestic electricity instead of imported diesel, which takes the largest single line out of the fuel import bill. It is sovereign: the energy is generated here and cannot be embargoed, turned back at sea or repriced by an insurer. And it frees the coast: about 1,200 kilometres of coastal rail and highway lose their through-freight as the trucks migrate inland, driven by economics rather than legislation.
Phase 0 is the 2,400 km Melbourne–Brisbane inland spine with seven spurs to the east-coast ports; the continental network then extends across the six corridors mapped on Phase Maps. Decarbonisation arrives as a by-product of the cheaper option winning, which is the only way it has ever arrived.
Cons: the existing system and current trajectory. Pros: the integrated MMA corridor programme.
Over a generation, Australian rail freight has been hollowed out. The network exists; the freight has migrated to road. Decarbonising freight on diesel B-doubles is structurally impossible.
The signature freight infrastructure project of the past decade was abandoned, with $3.8 billion redirected to a Melbourne metro loop. Australia has no national plan for moving freight other than diesel trucks on roads.
Australia imports 80-90% of refined fuel and runs approximately 30 days of diesel stock - well below the 90-day IEA obligation. Heavy freight is one major shipping disruption from collapse.
The single rail lines to Perth and Darwin have been cut by floods three times in four years (2022, 2024, 2026). National freight resilience does not exist as a property of the existing network.
Taree, Kempsey, Coffs Harbour, Grafton, Lismore, and a thousand kilometres of other coastal towns endure overnight B-double traffic that road infrastructure was never designed for. Quality-of-life degradation is continuous and ignored.
No state or federal programme is in place to electrify heavy freight rail at continental scale. The implicit current policy is that diesel road haul continues indefinitely, contradicting net-zero commitments.
The corridor carries three dedicated electrified freight tracks. Rail freight share restored - cheaper per tonne-km, lower emissions, faster, climate-resilient, not constrained by driver shortages or fuel imports.
Electrifying heavy freight collapses the largest single fuel-import burden the country carries. Transport energy converts from imported diesel to domestic electricity. Strategic vulnerability eliminated structurally.
Newcastle, Brisbane, Sydney, Melbourne, Adelaide, Fremantle, Darwin, Port Hedland, Gladstone, Mackay, Eden - every major export and import port connected to one national electrified freight network.
Elevated viaduct structure unaffected by the flood events that have cut the Perth and Darwin lines repeatedly. National freight resilience as a property of the corridor design.
Approximately 1,200 km of coastal rail and highway freed of freight as trucks migrate inland - driven by economics, not legislation. Coastal community amenity restored without political fight.
The continental electrified freight network gives defence logistics what it has not had in eighty years - sovereign, electrified, climate-resilient, continental-scale movement of equipment, fuel, and personnel.
