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, several of 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.
