The United States has gained control of or access to more than half of Australia’s military and defence facilities, according to a new database that has highlighted the growing scale of the American military presence across the country and raised questions about Australia’s strategic independence and the possibility of being drawn into a future conflict.
The analysis, compiled by the Nautilus Institute and reported, identifies 110 defence facilities across Australia where the US military or American defence companies either have control or some form of access. The figure includes 17 facilities directly controlled by the United States, 75 Australian-run facilities accessible to the US military and another 18 locations used by US defence corporations.
The findings suggest that the US military relationship with Australia extends far beyond a handful of well-known joint facilities. American personnel, military equipment and defence contractors now have a presence at locations across the country, supporting intelligence gathering, satellite surveillance, military training, logistics, weapons production and preparations for potential conflict in the Indo-Pacific.
Among the most strategically important locations is Pine Gap in the Northern Territory. The facility, formally known as a joint defence facility, is one of the most significant intelligence installations associated with the United States outside its own territory. Its systems are involved in tracking satellites, intercepting communications and providing information that can contribute to missile detection and military targeting. The facility has played an important role in US military operations around the world, although much of its work remains classified.
Other Australian facilities are also being adapted to support a larger US military footprint. At RAAF Base Tindal in the Northern Territory, runway expansion is intended to improve the facility’s ability to accommodate large American aircraft, including B-52 bombers. The US has also been developing logistics capabilities in Australia that could allow weapons, ammunition, fuel and military vehicles to be positioned closer to a potential conflict zone in the Pacific.
A new logistics facility at Bandiana in Victoria is one example. Announced earlier this year, the site is expected to support the pre-positioning of American military equipment for rapid deployment. Australian Defence Minister Richard Marles has argued that the growing American presence is important for strengthening Australia’s own defence capabilities and deterring potential conflict, particularly in view of China’s expanding military power.
The US presence is not limited to military personnel. American defence companies have access to numerous Australian military facilities for manufacturing, testing and training. Companies including Lockheed Martin and Northrop Grumman are involved in weapons-related production in Australia, contributing to efforts to increase allied interoperability and establish additional sources of ammunition and other military supplies.
The expansion has nevertheless generated concern among defence analysts and political groups. Richard Tanter, who helped compile the database, said the scale of American access should be viewed not simply as growing influence but as a form of “saturation” of Australia’s defence infrastructure. The database identifies 24 Australian facilities with both US military and corporate access, while 51 have US military access and 18 have US corporate access. Another 41 facilities were identified as having no significant US access, while the status of 17 remained unresolved.
Critics argue that Australia’s increasing integration with US military planning could reduce Canberra’s ability to maintain an independent foreign and defence policy. Some analysts have warned that facilities capable of supporting American military operations could make Australia a potential target or a staging ground in a future US-China conflict.
The Australian government, however, maintains that the country has no foreign military bases operating independently on Australian sovereign territory. Defence officials have stressed that Australia retains control over the deployment of the Australian Defence Force and the use of its territory, while describing the alliance with Washington as fundamental to national security.
The debate comes as Australia deepens its military cooperation with the United States through expanded exercises, logistics arrangements and the AUKUS security partnership. The government argues that closer cooperation is necessary to strengthen deterrence and prepare for a rapidly changing strategic environment in the Indo-Pacific.
But opponents fear that increasing dependence on American military infrastructure could create circumstances in which Australia becomes involved in a conflict without having made an independent decision to participate. With American military access now extending across a substantial portion of Australia’s defence infrastructure, the scale of the relationship is prompting renewed debate over whether the alliance makes Australia safer or exposes it to greater strategic risks.
