Northern Australia’s resilience in the face of crises depends not only on military facilities but on a network of civil infrastructure—ports, liquid-fuel facilities, airfields and logistics hubs that keep people, goods, and equipment moving.
Whether a crisis is military, environmental or humanitarian, northern Australia can hardly cope without them.
Increasingly, the question for Defence is not simply how to access and use these assets in an emergency, but how to shape their development from the outset—especially as more infrastructure is privately owned and operated. This requires moving beyond last-minute requisitioning and towards early engagement during project feasibility and planning, ensuring designs incorporate features that enable rapid military activation without undermining commercial viability.
Northern Australia’s vast distances and sparse population make duplication of infrastructure costly and inefficient. Multi-use or common-use assets—where capacity is shared under agreed terms—can deliver more capability at lower cost to government. Dual-use facilities, designed for both civilian and Defence purposes, can serve as a strategic multiplier when access rules and technical specifications are aligned with national security needs. Defence already relies heavily on civilian assets. The rearming of a Canadian warship from Darwin Port during Exercise Talisman Sabre 2025, and a similar operation in Broome the year prior, demonstrated the operational value of ensuring commercial facilities are Defence-ready.
Several current projects illustrate the potential for civil–military use. In Townsville, the Queensland Resources Common User Facility, designed to accelerate commercialisation of critical minerals production, can be configured to support Defence supply chains in a contingency if security, storage, and transport features are incorporated early. Darwin’s Middle Arm Precinct, planned as a multi-industry hub for renewable energy, low-carbon fuels, advanced manufacturing and critical minerals processing, will also host a ship lift useable for maintenance of private and Defence vessels.
In Western Australia, the Gascoyne Gateway Marine Complex, a privately funded, veteran-founded deep-water port near Harold E Holt naval communications facility and RAAF Learmonth, is designed for both commercial cargo and allied naval use, with integrated fuel and storage facilities. Further north, the Cockatoo Island Supply Base in the Kimberley, combining a deep-water port, airfield, and fuel infrastructure, will support offshore energy, border surveillance, Defence logistics, and emergency services.
These projects demonstrate how infrastructure designed with flexibility and resilience in mind can serve multiple markets over decades, particularly when backed by patient investors willing to wait for long-term returns.
Despite these opportunities, Defence’s engagement with infrastructure development remains sporadic and reactive. Without a deliberate policy framework, assets may be built to specifications that limit military utility, located in strategically sub-optimal places, or governed by access arrangements that slow response times in a crisis.
Governments must embed Defence in early-stage planning for major infrastructure projects in northern Australia, establishing clear technical and security standards that can be incorporated into commercial builds and negotiate long-term access agreements with owners and operators. This also means that Defence must pay for enhancements which it needs but commercial customers don’t. It needs to pay up front or agree in advance on usage charges that justify the cost of the special features for the developer.
In an era of contested supply chains, extreme weather and regional uncertainty, critical infrastructure will be as vital to national security as any weapons system. Building this capability in Northern Australia requires more than opportunistic use; it demands deliberate, coordinated planning that aligns commercial development with strategic priorities. Early, sustained engagement between Defence, state and territory governments, and private investors is the only way to ensure the infrastructure we build today can strengthen our resilience to future challenges.
