Switzerland successfully maintained its neutrality during conflicts by constructing an extensive network of bunkers and concealed artillery, effectively deterring invasions from both Italy and Germany. The cost of an invasion for these nations proved too great. In contrast, Australia presents a low-risk, high-reward target for potential aggressors.
The Chinese are unlikely to repeat the mistakes of the Japanese during World War II by failing to invade Australia and allowing the United States to regroup, resupply, and retaliate. We owe a significant debt to the U.S. for their role in the Battle of the Coral Sea, but today’s threats may not require a conventional invasion. Instead, there could be a surge of armed insurgents accompanied by thousands of aging cargo ships—many built in China—carrying war refugees, along with hidden missile platforms. It’s unlikely we would sink vessels suspected of being part of a Chinese military operation, that carry war refugees. Once these ships reach Australian soil, our options may dwindle to sending our armed police and the Australian Defence Force into the jungles of North Queensland.
This context may shed light on why the Chinese military pursued jungle warfare training in Brazil—there are limited jungle environments in the South China Sea! One must question why they would invest in jungle training if their strategic plans do not involve fighting in such terrain. North Queensland is a land of coastal jungles.
