Abstract: There is a growing consensus among defence planners that Australia is in need of a new defence policy that better suits the strategic realities of an emerging multipolar Asia. After assessing the implications of shifting regional power balances for Australia, this article advances the argument that Australia should redirect its attention back to its immediate north: the “Indo-Pacific Arc”. Indonesia, Singapore, and Malaysia have always been vitally important to Australia’s long-term security and, being the gateway between Indian and Pacific Oceans, their strategic value is set to dramatically increase in the multipolar Asia. Finally, this article develops the case for Australia to partner with its neighbors to stem the political and military influence of outside powers into the Indo-Pacific Arc.
