Australia’s next fight will be won or lost in the logistics battlespace. In the Indo-Pacific, supply chains have moved from the background to the foreground of strategy, and Australia’s north now sits on the forward edge of that contest.
From just-in-time to just-in-case
For decades, advanced economies optimised logistics for efficiency. Just-in-time was king: lean inventories, centralised hubs and finely tuned global supply chains designed to minimise cost and maximise speed.
That era is over. Australia is now moving into a world of just-in-case logistics, where reserves, redundancy and options matter more than minimal stockholdings and lowest-cost routing.
But changing the inventory policy is not enough; the national mindset must change as well. For the first time since the Cold War, Australia must think seriously about state-on-state conflict and the possibility that an adversary will deliberately target logistics systems in peacetime, crisis and war.
That is a profound shift for a country whose recent operational experience has largely involved deployments in which supply lines were secure, coalition-managed and distant from direct attack. Just-in-case logistics is therefore not nostalgia for brimming fuel reserves and warehouses full of spares. It is a deliberate posture that accepts higher peacetime costs and complexity in exchange for the ability to endure coercion, disruption and, at worst, armed conflict.
Crucially, this mindset extends beyond defence. Energy security, critical minerals, pharmaceuticals, food systems, digital infrastructure and finance all sit within the new logistics battlespace.
From factory to foxhole
In a contested region, an adversary can interfere from factory to foxhole: physically, digitally, financially, legally and in the information domain. Ports, airfields, fuel farms, data links, software platforms, customs systems, undersea cables, commercial contracts and insurance markets are no longer background enablers; they are targets and levers.
Geography remains central. The Strait of Hormuz, the Taiwan Strait and the Strait of Malacca are obvious physical chokepoints, but the picture is broader. To Australia’s immediate north and west, the Sunda and Lombok Straits provide alternative corridors that are narrower, deeper and easier to monitor or disrupt, and together with Malacca they form a connected system of sea lanes that any serious adversary would study closely.
Alongside these sit digital and financial chokepoints. Undersea cables, space-based data links and data centres underpin everything from port operations to inventory management, while payment systems and insurance markets can amplify the effects of physical disruption.
The lesson is blunt: tomorrow’s battles will be fought not only with ships, aircraft and missiles, but also through supply chains. Supply chains themselves are becoming the new front lines.
Disruption, blockade and severed supply
Much of the public debate focuses on disrupted supply chains – delays, diversions and temporary outages. In a serious conflict, Australia must also consider severed supply chains in which specific routes, commodities or capabilities are cut off for prolonged periods by blockade, mining, physical damage, cyberattack or regulatory coercion.
For a country deeply integrated into global trade but geographically distant from most manufacturing centres, that prospect is sobering. Fuel, munitions, advanced components, pharmaceuticals and critical minerals processing are all vulnerable to elongated or severed supply.
Rare earths illustrate the point well. Australia is rich in rare earth resources, but processing and downstream manufacturing remain concentrated offshore, so a crisis affecting those nodes would not just disturb prices. It could also cut access to essential inputs for advanced weapons systems, electronics and energy technologies.
Planning for contested logistics, therefore, means planning for scenarios in which some flows cannot be restored quickly, if at all. Rerouting buys time, but it also consumes capacity and creates new chokepoints elsewhere.
Sovereignty and industrial depth
In this environment, logistics and industry policy converge. Sovereign capability is no longer an abstraction; it is the practical question of which functions must exist in Australia, or within trusted coalitions, for the country to withstand prolonged disruption.
Sovereignty does not mean seeking to exist without external trade or reliance on foreign aid. It means having enough national and coalition capacity to absorb shocks while alliances and markets adapt. In the current strategic context, offshoring with hopes and prayers is no longer an acceptable risk.
Just-in-case logistics directly supports greater national self-sufficiency in critical areas. That includes fuel reserves sized and located to support both the Australian Defence Force and the economy under stress. It involves building munitions stockpiles and surge manufacturing capacity, and bringing repair and maintenance capability forward rather than relying on southern depots. And it involves strengthening selected domestic production and refinement where interruption would impose strategic cost.
Central to this effort should be additive manufacturing, which is offered by many companies in Australia, including one of which I’m a non-executive director. Properly integrated, distributed additive manufacturing hubs could produce critical components closer to the point of need, support rapid battle-damage remediation in theatre, and reduce dependence on long, fragile resupply chains for low-volume, high-consequence items.
It is not a silver bullet. Additive manufacturing still depends on secure digital designs, reliable materials, skilled technicians and quality assurance. But as part of a more self-reliant industrial base, it offers a powerful means of turning time and knowledge into resilience.
The north, a crossroad at the front door
Australia is both exposed and indispensable. It relies on secure sea lanes for trade and fuel, yet it also possesses geography, resources and alliance access that matter enormously to partners.
The Northern Territory is no longer a remote support zone. It is an operational frontage where geography, alliance posture, infrastructure, supply chains and operational readiness intersect. RAAF Darwin, RAAF Tindal, training areas, the Darwin Harbour and associated infrastructure enable dispersal, regeneration and sustained air-maritime operations.
But they also face new demands and constraints. If the north is to function as a genuine multi-user logistics hub for Defence, resources, energy and regional partners, it needs more resilient airfields, additional fuel storage, improved road and rail connectivity. It also needs greater intermodal transfer capacity, upgraded port and repair facilities, secure data infrastructure and a more deeply trained workforce. And these must all be delivered sooner than the current schedule.
No middle power can achieve comprehensive resilience on its own. Just-in-case logistics should push Australia towards deeper integration with allies and partners through integrated logistics hubs, shared fuel and sustainment infrastructure, common data standards and pre-agreed access arrangements for ports, airfields and maintenance facilities.
Australia should also disperse and diversify industrial capacity across trusted coalitions. Rather than every state seeking a full national production chain, partners should map critical functions, identify real single points of failure and decide where redundancy is best located across the network.
Perhaps the most underappreciated requirement is that some capabilities must exist in peacetime, in case they are needed to surge in crisis or conflict. Complex industrial and logistics capabilities cannot be switched on at short notice. They require a continuously practising workforce, maintained equipment, viable business models and regulatory familiarity.
That has uncomfortable implications for governments. In some areas, the state will need to support the mere existence of capabilities that may appear inefficient in normal market conditions but are essential for national endurance. Skills, capacity and organisational muscle memory should be sustained before the crisis arrives, not improvised after it begins.
A whole-of-nation need for speed
Contested logistics is ultimately about time: time to detect, move, repair, reroute, surge and endure. Nations that can maintain operational tempo while absorbing disruption gain a major strategic advantage.
Building that advantage is not a task for Defence alone. Federal, state and territory governments, regulators, ports, freight operators, miners, energy companies, telcos, software vendors, financiers and universities all sit inside the same system and all need a common picture of risk.
Australia is entering a decade in which logistics resilience will be inseparable from deterrence and defence. If the country can build physical, digital and financial logistics systems that function under pressure, recover quickly and sustain action over time, contested logistics will become not only a vulnerability to manage but also a source of national strength.
