Australia is a nation and continent between the Pacific and Indian Oceans of approximately 22 million people. Australia has one of the highest standards of living in the world. Its capital is Canberra, and its largest city is Sydney.
Australia was inhabited by the Aboriginals nearly 40,000 years ago. Since they had no written language, there is no historical documentation of this period.
Later, Australia became a regular colony, and an integral part of the British Empire. Australia send troops to World War I, with a notable number of Australian soldiers participating in the Gallipoli Campaign.
Australia gained a degree of independence during the 1930s, but was still under British suzerainty during World War II, when it was directly threatened by the Empire of Japan. However, the victory at the Battle of the Coral Sea stalled the Japanese advance and saved Australia. Australia gained independence after World War II, and was aligned with the United States during the Cold War.
