Diplomatic history of Australia

The diplomatic history of Australia encompasses the historical events surrounding Australian foreign relations. Following the global change in the dynamics of international state of affairs in the 20th century, this saw a transition within Australia's diplomatic situation to broaden outside of exclusively commonwealth and western European nations. Its core relationship was with Great Britain until 1941, and with the United States and New Zealand since then as represented by ANZUS. In the 21st century trade has soared with China. However relations have cycled back and forth from friendly to strained. For recent relations see also Foreign relations of Australia.
