Japan and Australia: Toward a More Autonomous and Resilient Partnership

Japan and Australia have deepened their comprehensive security partnership across military and economic domains while maintaining their respective alliances with the United States. The article argues that neither replacing dependence on the United States with dependence on China nor pursuing economic decoupling from China is viable, and that the goal is instead to diversify dependence. It cites the Australian Navy's acquisition of Japanese-designed Mogami-class frigates and a regional initiative such as "POWERR Asia" as examples of cooperation on defence industrial capacity and energy resilience.

Why it matters: The article places Japan–Australia defence-industrial and energy cooperation within the briefing's economic security theme, presenting the diversification of dependence, rather than decoupling, as the response to intensifying great-power competition.
