Australia has backed away from a proposed base on its west coast for a United States carrier strike group, including nuclear submarines and guided missile cruisers.
The proposal, in a list of options for strengthening the US counterbalance to China in the Pacific, also suggested basing more strike jets in Australia and increasing the new rotational deployment of a 2500-strong Marine task force in the Northern Territory.
But while affirming that no American bases would be established, Defence Minister Stephen Smith repeated Canberra's commitment to a more powerful US presence in the region and increased access to Australian naval, air force and army facilities.
Identifying the rise of China and India as key elements in a continuing strategic power shift, Smith told the Australian Strategic Policy Institute: "Substantially enhanced practical co-operation between Australia and the US is an essential part of Australia's contribution to regional peace and stability."
The proposal to build a carrier strike force base costing up to US$7 billion ($8.65 billion) at the naval base HMAS Stirling, near Perth, was one of four main options presented in a study by America's Centre for Strategic and International Studies for the congressional armed forces committee.
