The Australia-United States Alliance has been critical to Australian foreign and defence policy since the ANZUS Treaty was signed in 1951. For 63 years it has been an enduring feature of Australian defence planning, yet the contemporary alliance is, arguably, in one of the more important phases of reinterpretation in its long history.

Despite the critical importance of the Australian-US Alliance and the evolving nature of the regional and global strategic environment there have been few studies that attempt to provide an in-depth understanding of how the Alliance is developing, and what this means for Australian defence policy. Australia’s American Allianceaims to fill this significant gap in order to provide the general public, policy and academic communities a more nuanced understanding of the Alliance and related choices for Australia, that will provide for a better informed debate over the future of Australia’s most significant strategic partnership.
