Ancestry and immigration

Between 1788 and the Second World War, the vast majority of settlers and immigrants came from the British Isles (principally England, Ireland and Scotland), although there was significant immigration from China and Germany during the 19th century. In the decades immediately following the Second World War, Australia received a large wave of immigration from across Europe, with many more immigrants arriving from Southern and Eastern Europe than in previous decades. Since the end of the White Australia policy in 1973, Australia has pursued an official policy of multiculturalism, and there has been a large and continuing wave of immigration from across the world, with Asia being the largest source of immigrants in the 21st century.

Today, Australia has the world's eighth-largest immigrant population, with immigrants accounting for 30% of the population, the highest proportion among major Western nations. 160,323 permanent immigrants were admitted to Australia in 2018–2019 (excluding refugees), whilst there was a net population gain of 239,600 people from all permanent and temporary immigration in that year. The majority of immigrants are skilled, but the immigration program includes categories for family members and refugees. In 2020, the largest foreign-born populations were those born in England (3.8%), India (2.8%), Mainland China (2.5%), New Zealand (2.2%), the Philippines (1.2%) and Vietnam (1.1%).

The Australian Bureau of Statistics does not collect data on race, but asks each Australian resident to nominate up to two ancestries each census. These ancestry responses are classified into broad standardised ancestry groups. At the 2021 census, the number of ancestry responses within each standardised group as a proportion of the total population was as follows: 57.2% European (including 46% North-West European and 11.2% Southern and Eastern European), 33.8% Oceanian, 17.4% Asian (including 6.5% Southern and Central Asian, 6.4% North-East Asian, and 4.5% South-East Asian), 3.2% North African and Middle Eastern, 1.4% Peoples of the Americas, and 1.3% Sub-Saharan African. At the 2021 census, the most commonly nominated individual ancestries as a proportion of the total population were:

English (33%)

Australian (29.9%)

Irish (9.5%)

Scottish (8.6%)

Chinese (5.5%)

Italian (4.4%)

German (4%)

Indian (3.1%)

Aboriginal (2.9%)

Greek (1.7%)

Filipino (1.6%)

Dutch (1.5%)

Vietnamese (1.3%)

Lebanese (1%)

At the 2021 census, 3.2% of the Australian population identified as being Indigenous — Aboriginal Australians and Torres Strait Islanders.
