The White Australia policy was a set of racist policies that aimed to forbid people of non-European ethnic origins – especially Asians and Pacific Islanders – from immigrating to Australia in order to create a "white/British" ideal focused on but not exclusively Anglo-Celtic peoples. Pre-Federation, the Australian colonies passed many anti-Chinese immigration laws mainly using Poll Taxes, with Federation in 1901 came discrimination based on the Dictation Test, which effectively gave power to immigration officials to racially discriminate without mentioning race. The policy also affected immigrants from Germany, Italy, and other European countries, especially in wartime.Governments progressively dismantled such policies between 1949 and 1973. At first these changes were due to international pressure and were token modifications designed to maintain a white Australia until the Whitlam government removed the last racial elements of Australia's immigration laws.

The Australian continent was first settled when ancestors of Indigenous Australians arrived via the islands of Maritime Southeast Asia and New Guinea over 50,000 years ago.
