Immigration has been a key to Australia's development since the beginning of European settlement in 1788. For generations, most settlers came from the British Isles, and the people of Australia are still predominantly of British or Irish origin, with a culture and outlook similar to those of Americans. However, since the end of World War II, the population has more than doubled; non-European immigration, mostly from the Middle East, Asia, and Latin America, has increased significantly since 1960 through an extensive, planned immigration program. From 1945 through 2000, nearly 5.9 million immigrants settled in Australia, and about 80% have remained; nearly two of every seven Australians is foreign-born. Britain and Ireland have been the largest sources of post-war immigrants, followed by Italy, Greece, New Zealand, and the former Yugoslavia.

Australia's humanitarian and refugee admissions of about 12,000 per year are in addition to the normal immigration program. In recent years, refugees from Africa, the Middle East, and Southwest Asia have comprised the largest element in Australia's refugee program.

Although Australia has scarcely more than two people per square kilometer, it is one of the world's most urbanized countries. Less than 15% of the population lives in rural areas.

Australian actors such as Nicole Kidman, Rachel Griffiths, Cate Blanchett, Russell Crowe, Geoffrey Rush, Paul Hogan, Hugh Jackman, Heath Ledger, and childrenís entertainers, The Wiggles, have achieved enormous popularity in the United States. Australian movies and directors such as Peter Weir and Philip Noyes also are well known.

Australia has had a widely respected school of painting since the early days of European settlement, and Australians with international reputations include Sidney Nolan, Russell Drysdale, and Pro Hart and Arthur Boyd. Writers who have achieved world recognition include Thomas Keneally, Colleen McCullough, Nevil Shute, Morris West, Jill Ker Conway, and Nobel Prize winner Patrick White.
