In 1945, Australia’s population was around 7 million people and was mainly Anglo–Celtic. Since then, more than 6.5 million migrants, including 675 000 refugees, have settled in Australia, significantly broadening its social and cultural profile. Today Australia has a population of nearly 23 million people. In 2009, about 25.6 per cent of the estimated resident population comprised those born overseas. Australian Bureau of Statistics projections from the 2006 census of the numbers of Aboriginal and Torres Strait Islander people suggests an Indigenous population of 575,552 people at 30 June 2011.
