This paper examines the prospect and utility of closer defence cooperation for both Canada and Australia. It reflects on commonalities and like-mindedness, particularly as they concern regional security and stability in the Indo-Pacific. Forward-looking measures are presented for Canadian and Australian defence policy makers to capitalize on each other’s strengths and similarities. Cooperation could enhance both countries’ ability to engage in the region, their mutual defence capabilities and their engagement with the great powers. With this in mind, closer bilateral engagement should be considered in three areas: bolstering regional engagement, cost-saving measures and enhancing engagement with great powers.
