Research by the Nautilus Institute, published by Guardian Australia, identified 110 facilities where US military or defence-industry interests have some level of control or access. Of those, 17 are US-controlled facilities where Australia has access, while the American military can use another 75 Australian-run defence facilities. US defence corporations have access to a further 18 sites. The figures mean American military interests have a presence at more than half of the defence facilities examined across Australia. Professor Richard Tanter of the Nautilus Institute, who compiled the database, described the scale of integration as a “saturation” of Australia's defence infrastructure rather than simply American penetration of the country's military system. The facilities perform vastly different functions. Among the most strategically important is Pine Gap near Alice Springs, the highly secretive joint US-Australian intelligence facility that collects signals intelligence and receives data from American satellites. Pine Gap plays a significant role in detecting missile launches, intercepting military communications and providing intelligence that can be used to support US military operations around the world. It has long been regarded as one of Washington's most important intelligence facilities outside the United States. Elsewhere, American forces have expanded their access to Australian airfields, naval facilities, training grounds, communications infrastructure and logistics hubs. RAAF Base Tindal in the Northern Territory is being upgraded to accommodate US aircraft including B-52 strategic bombers, while RAAF Base Darwin supports the annual rotation of US Marines and sailors through northern Australia. Around 2,000 US Marines and sailors arrived for the 2026 Marine Rotational Force–Darwin deployment, which lasts approximately six months and includes exercises in Australia and across the Indo-Pacific. Australia's Defence Department says the programme improves interoperability between the two militaries and allows them to train with regional partners. The rotations began with about 200 Marines in 2012 and have grown substantially since then. The expanding American footprint is part of the broader United States Force Posture Initiatives agreed between Canberra and Washington. Under those arrangements, Australia and the US have been upgrading bases including Darwin and Tindal while examining further improvements at RAAF Bases Scherger in Queensland and Curtin in Western Australia. The two governments have also agreed to expand the pre-positioning of US equipment, munitions and fuel in Australia. The strategy is intended to allow American forces to operate more quickly across the Indo-Pacific during a crisis without having to move every aircraft, weapon or supply from bases thousands of kilometres away. Australia's strategic importance is likely to increase further under AUKUS. From 2027, US Virginia-class and British Astute-class nuclear-powered submarines are expected to begin rotational deployments to HMAS Stirling near Perth under Submarine Rotational Force–West, before Australia eventually acquires its own nuclear-powered submarines. Washington and Canberra announced further plans last week to strengthen US force posture in Australia, with Defence Minister Richard Marles and US Defence Secretary Pete Hegseth presenting the expansion as part of efforts to strengthen deterrence and stability across the Indo-Pacific. But the scale of the American presence is also fuelling a debate over Australian sovereignty. Critics argue that the increasingly interconnected command, intelligence and logistics architecture could make it difficult for Canberra to remain outside a future American conflict, particularly a confrontation involving China. Some analysts have gone further, describing the growing US military footprint as a form of “colonisation” or “voluntary subordination.” The Australian government rejects the suggestion that the arrangements undermine its sovereignty. Canberra describes the US alliance as central to Australia's national security and says the Force Posture Initiatives allow the two countries to respond more effectively to regional crises, including humanitarian and disaster-relief operations. The new database nevertheless illustrates how deeply the American military has become embedded in Australia's defence infrastructure. From intelligence facilities in the centre of the continent to bomber-capable airfields in the north and submarine infrastructure in the west, Australia is increasingly becoming an important operational and logistical platform for US forces in the Indo-Pacific. The strategic calculation for Canberra is that this integration strengthens deterrence and makes Australia safer. The increasingly prominent counterargument is that the same infrastructure could make it harder for Australia to decide independently whether it participates in America's next major war.
