The Championship of Australia was an Australian rules football tournament which was contested between football clubs from the Victorian, South Australian, Western Australian and Tasmanian football leagues. The Championship took place three times in the 19th century and then from 1907 to 1914—with the exception of 1912—and every year from 1968 to 1975. All but two of the Championships were played in Adelaide, and all of them occurred after the respective league seasons had ended. The 1975 Championship of Australia was the last edition of the competition, with the 1976 NFL Championship replacing the format, albeit for only one year with VFL clubs.
