The US military is planning a permanent war-ready weapons stockpile for its Marine Corps on Australia’s southeast coast beyond the range of most Chinese missiles, tender documents show and officials confirmed to AFP.
The development of the stockpile, a first for the Marine Corps in Australia, comes as the United States is keen to leverage the continent’s strategic location in the South Pacific to counter China’s rapid military build-up, analysts said.
The US Marines Corps began global prepositioning of military supplies during the Cold War — using floating stores on ships and caves in Norway where weapons, ammunition and vehicles to sustain thousands of troops are kept.
The first land stockpile in the Asia-Pacific is expected to open this year in the Philippines, close to potential flashpoints in the South China Sea.
Documents published by the US Navy this month show advanced planning for an even larger Australian stockpile, with $30 million allocated to build warehouses and offices in southeastern Victoria state for “critical forward provisioning”.
The Australian stockpile, expected to reach full capacity by 2028, will be kept in Melbourne before being moved to US warehouses to be constructed next year at an Australian military base at Bandiana in rural Victoria, tender documents show.
Australia does not permit foreign military bases on its soil, a sensitive issue in a country that has a security alliance with the United States and is hosting an increasing variety of US forces on rotation at Australian defence bases.
The US Navy is engaging a global defence contractor to employ around 110 engineers, mechanics, material and safety specialists to manage the Australian stockpile, which includes “crew-served weapons”, the documents show.
“Marine Corps activities in Australia support integrated global sustainment by maintaining ready-for-issue equipment and supplies for operations and exercises across the Indo-Pacific,” a US Marine Corps Forces Pacific spokesperson told AFP.
The spokesperson declined to comment on contract details or force planning assumptions but said Marines equipment is kept at “high readiness”.
Contracting arrangements and the operation of the facility would be made in close coordination with Australia’s Department of Defence.
“These activities improve responsiveness, strengthen interoperability with allies and partners, and support a range of missions across the Indo-Pacific,” the spokesperson said, using an alternative description for the Asia-Pacific region.
US Army trucks were left at the Bandiana base in 2023 after an Australian war game involving US troops held every two years. The Marines stockpile at Bandiana, approved last July, is separate.
“Marine Corps and Army equipment programmes are designed to support their respective service requirements and are managed under separate authorities and processes,” the Marines spokesperson said.
Australia’s Department of Defence did not respond immediately to a request for comment.
Beyond China’s missiles?
The Pentagon has asked Congress for $500 million next year to improve prepositioning of equipment and fuel across the Asia-Pacific to deter China.
Around 2,000 US Marines conduct exercises for six months of the year on the opposite coast of Australia in the northern city of Darwin.
A report from the Lowy Institute think tank this week warned that China has the capability to strike northern Australia with ballistic missiles deployed from its South China Sea outposts.
Its director of international security, Sam Roggeveen, told AFP that it was likely a “relevant consideration” in placing a stockpile in Australia’s southeast.
“Once these facilities are operational, they would be obvious targets for China,” he said.
The growth of US forces and equipment in Australia is “a major change to Australian policy that ties Australia much more closely to America’s strategic objectives in the region”, Roggeveen said.
Australian National University professor of international security John Blaxland said the country’s location is being seen with “a growing sense of significance” given concerns over the vulnerability of the US military base on Guam.
“With competition for influence in the Indo-Pacific having reached the highest level in over a generation, it is not surprising that the US Marines might look to Australia to enable such storage,” he said.
“Barring a massive increase in Australian defence expenditure, for which there is little political appetite, facilitating greater US investment in Australian real estate is widely considered to be the most prudent approach to take.”
