Girt by Sea: Finding security in Australia’s maritime domains
Girt by Sea: Reimagining Australia's Maritime Security
Australia is a maritime nation — yet for too long its strategic thinking has underestimated what that truly means. From the Torres Strait to the Southern Ocean, the seas that surround Australia are not just geography; they are the front lines of its national security.
In this Lowy Institute conversation, the authors of Girt by Sea: Reimagining Australia's Security joined Director of Research Hervé Lemahieu to make the case for a fundamentally different way of understanding Australia's strategic challenges. Professors Rebecca Strating and Joanne Wallis examined six maritime domains central to Australia's national interests — the Timor, Arafura and Coral Seas and the Torres Strait, the Western Pacific, the South China Sea, the South Pacific, the Indian Ocean, and the Southern Ocean — and offered a compelling alternative vision for how Australia should think about security in each.
Wide-ranging, rigorously argued, and deeply relevant to Australia's strategic moment, this is essential viewing for anyone engaged with the future of Australian foreign and defence policy.
