Australian people, or simply Australians, are the citizens of Australia. Australia is a multi-ethnic nation, and therefore the term "Australian" is not a racial identifier. Aside from the Indigenous Australian population, nearly all Australians or their ancestors immigrated within the past 230 years. Colloquial names used to refer to Australians include Aussies, and Antipodeans.
The mainstream Australian culture (occasionally defined as the Anglo-Celtic culture), is a Western culture largely derived from the traditions of Western European migrants beginning with the early settlers from England, Scotland, and Ireland. The populations of Sydney, Melbourne and the other major cities are different from the demographics of rural Australia as a result of the differing migration patterns.
