Brisbane Line (military strategy)

The Brisbane Line was a strategic concept proposed during World War II by Australian military planners, suggesting that in the event of invasion, Australia could prioritize defending its eastern and southeastern coastlines while allowing less critical inland areas to be bypassed or sacrificed. The idea aimed to focus resources on protecting key population centers and military assets, potentially withdrawing from remote regions to conserve strength. Although influential in planning discussions, it was never officially adopted as a formal strategy but reflected concerns about the country's limited resources and the need to defend vital areas effectively.
