Australian defence policy sits at a crossroads. For over 70 years Australia?s strategic position had been anchored by the US led international order that has been in place since 1945. But in '2017 Australians had to acknowledge that the global order that had shaped the world since the end of World War II was not challenged or changing but over?. In this new era, beset with rapid strategic and technological change underpinned by increasing US-China contestation in the Indo-Pacific, what does the future hold for the region and Australia?s strategic approach? Like its companion volumes, Australia?s Defence- Towards a New Era? (2014) and Australia?s American Alliance (2016), this book brings together leading experts to examine the future of Australian defence policy in a contested Asia. This thought provoking and challenging volume imagines the future of Australian strategy after American primacy, plotting possible, probable and preferable strategic futures for a country that faces unprecedented strategic challenges.
