We must be vigilant against both traditional and unconventional threats

August 4, 2025

I’m writing to respond to the discussions surrounding Australia’s defense strategy, especially in light of Angus Houston’s comments in the Defence Strategic Review. While some argue that Australia faces minimal risk of a land invasion, we must consider historical lessons, particularly from World War II.

Japan’s decision not to invade Australia was a significant strategic error. Their resources were stretched, and focusing on Australia would have jeopardised their campaigns in Southeast Asia. Today, Australia’s enhanced military capabilities and strong alliances, particularly with the US, create formidable deterrents against potential aggressors.

However, we should contemplate unconventional threats, such as an invasion using aging cargo ships and China’s naval militia to facilitate the arrival of displaced refugees accompanied by armed insurgents. Intercepting such vessels before they reach our shores presents a serious challenge, especially given the moral dilemmas democracies face regarding humanitarian concerns.

Furthermore, reports of China conducting jungle warfare training in Brazil raise alarms about their strategic intentions. As we navigate these complexities, it is crucial to remain vigilant and prepared against both traditional and unconventional threats to ensure Australia’s security.
