Why was Australia not colonized by Asia?

Answer 1

Asia is not one country. It can't "colonize" in that sense. But if we think about this question from another angle, namely why was Australia never colonized by any Asian nation, then several things come to mind. First, Australia is far away from Japan and China and other Asian countries, and this distance hindered travel and communication for a long time. Later, when the British had colonized Australia, the presence of the British military was an effective barrier to interference by other nations in the region. Third, one Asian nation, Japan, had military plans to invade Australia during the Second World War. However, these plans were never put into action, perhaps primarily because the Japanese had more than enough other things to deal with at the time. The possibility of such an invasion was a real threat for several years during the war and the Australian government had made plans to counter it.
