List of SEABL champions

Below is a list of South East Australian Basketball League (SEABL) champions for both the men's and women's competitions. The men's competition ran from 1981 to 2018, while the women's competition ran from 1990 to 2018.

Men
The champions of the SEABL from 1981 to 1994 were all identical to those who finished on top of the regular-season ladder. From 1995 to 2007, there were conference grand finals that determined the conference champions.

In 2008, a SEABL grand final was held between the South and East conference champions and an overall SEABL champion was crowned for the first time since 1985. The conference system was scrapped by the SEABL in 2018, with a top eight finals structure taking its place.

Women
The SEABL women's competition was first introduced in 1990. In 2012, the women's competition was divided into two conferences for the first time due to five new women's teams having joined the SEABL since 2006—Brisbane (2007), Sandringham (2009), Hobart (2010), Geelong (2011) and Canberra (2012). Canberra's addition in 2012 expanded the league to 14 teams. The conference system was scrapped by the SEABL in 2018, with a top eight finals structure taking its place.
