The Australian Chess Championship is a tournament organised by the Australian Chess Federation and held every two years. The tournament is usually restricted to Australian chess players, although exceptions have been made on occasion. The winner of the tournament holds the title of Australian Chess Champion until the next tournament is held. The tournament format is normally a restricted Swiss system, and in case of a tie for first place, a playoff match or tournament is conducted.
Since 1971, the Australian Open has been held in the intervening years. This event is open to all players, regardless of nationality, and the winner holds the title of Australian Open Champion.
The Australian Junior Championship and Australian Girls Championship are held annually. The Australian Women's Championship was previously organised as a separate tournament but current regulations award the title of Australian Women's Champion to the highest placed Australian female player in the Australian Open (dependent on a minimum number of female entries).
The tournament usually begins in late December (after Christmas) and finishes in January. In the table, the year refers to the date the tournament finished.
