As tensions mount in the Indo-Pacific region, new constellations of power have emerged to address the challenges of strategic competition. Australia has joined forces with Japan, the US, India and the UK in a variety of strategic minilateral institutions including the Quad, AUKUS and the much-overlooked Australia-Japan-US Trilateral Strategic Dialogue. As regional rivalries intensify, significant questions remain to be explored as to the nature, purpose and impact of these new strategic minilateral formations. This book launch talk will share the findings of the author’s research – conducted under the auspices of a Japan Foundation Fellowship (2023-24) – to offer fresh insights into the role of such minilaterals in shaping the regional order into the future.
