European Australians are citizens or residents of Australia whose ancestry originates from the peoples of Europe. They form the largest panethnic group in the country. At the 2021 census, the number of ancestry responses categorised within European ancestral groups as a proportion of the total population amounted to more than 57.2% (46% North-West European and 11.2% Southern and Eastern European). It is impossible to quantify the precise proportion of the population with European ancestry. For instance, many census recipients nominated two European ancestries, tending towards an overcount. Conversely, 29.9% of census recipients nominated "Australian" ancestry (categorised within the Oceanian ancestry group, although most of them are likely to be of Anglo-Celtic or European ancestry), tending towards an undercount.
Since the early 19th century, people of European descent have formed the majority of the population in Australia. Historically, European immigrants had great influence over Australian culture and society, which resulted in the perception of Australia as a European-derived country.
The majority of European Australians are of British Isles – English, Irish, Scottish, or Welsh – ancestral origin. While not an official ancestral classification, they are often referred to as Anglo-Celtic Australians. Other significant ancestries include Italian, German, Greek, Dutch, European New Zealanders, Polish, Maltese, and Scandinavian.
The Australian Bureau of Statistics and Australian Census does not collect data based on race. Instead, it collects information on distinct ancestries, of which census respondents can select up to two.
