Australians, colloquially known as
Aussies, are the citizens, nationals and individuals associated with the country of Australia. This connection may be residential, legal, historical or ethno-cultural. For most Australians, these connections exist and are collectively the source of their being Australian. Australian law does not provide for a racial or ethnic component of nationality, instead relying on citizenship as a legal status, though the Constitutional framers considered the Commonwealth to be "a home for Australians and the British race alone", as well as a "Christian Commonwealth". Since the postwar period, Australia has pursued an official policy of multiculturalism and has the world's eighth-largest immigrant population, with immigrants accounting for 30 percent of the population in 2019.
