As someone who lived in Australia for an extended period of time, it amuses me to no end the willingness Australians display in offering themselves as cannon fodder for the American empire. There are quite literally a million and one ways the CCP could collapse this country. The most pain-free would be to block students from enrolling in Australian universities, thereby collapsing the Australian tourism and higher education sector overnight. This would come at no cost to China, in fact it would be a net positive considering the quality of Aussie universities. The most devastating method would be to stop imports of iron ore and send Australia into the 2008 recession they missed out on. China will do this gradually as Brazilian and African mines are established, and on its transition to renewables.
Hopefully Russia will export more iron ore to China now that iron ore exports to Europe have been sanctioned. This can reduce China’s imports of Australian iron ore.
