List of ABA National Champions

The champion teams of the Australian Basketball Association (ABA) National Finals were determined by grand final championship games at the conclusion of the finals weekend.

The men's and women's champion from each ABA conference alongside a number of wildcard teams competed at the ABA National Finals every year between 1981 and 2008 except for 2001 when the event was cancelled due to the collapse of Ansett Airlines. The ABA National Finals were known as the Australian Club Championships (ACC) in 2007 and 2008. The ABA and ACC was abandoned following the 2008 season.

Conferences
The ABA was established in 1981 and operated under many different names and structures until 2008.

The conferences included:
 * South East Australian Basketball League (SEABL), 1981–2008
 * Queensland Basketball League (QBL), 1994–2008
 * Central Australian Basketball League (Central ABL), 1998–2008
 * Big V, 2000–2008
 * Waratah League, 2001–2008

Historial records
The ABA's roots can be traced back as far as 1965 when the South Eastern Conference (SEC) was established. The SEC continued until 1971 when the Australian Club Championships gained pre-eminence. The Australian Club Championships ceased operations after 1980 due to the rise of Australia's first truly national competition, the National Basketball League (NBL).

Melbourne Church of England, later becoming Melbourne Tigers, won the SEC in each of its six seasons.
