Background Kalamunda & Districts Basketball Association (KDBA) was incorporated on 1 October 1971. In 1991, KDBA affiliated with
Basketball Western Australia and entered teams as the Kalamunda Hornets in the WA Junior State League competition. In 2001, Eastern Region Basketball Association (ERBA) was established as a junior representative association following the amalgamation of KDBA, Swan Mustangs (SDBA), and Mundaring (HRBA). The teams played as the Eastern Suns. Initially there was input from all three associations, but this deteriorated when SDBA found themselves in financial difficulty with increasing debt to Basketball Western Australia. KDBA was in a position to seek a license from the
State Basketball League (SBL) but was unwilling to assume the SDBA debt as part of their license (in excess of $40,000). The
Swan City Mustangs SBL club and the Association ceased to operate following the 2003 season. with the women's team reaching the semi-finals in their first season. In the
2013 season, the women's team made their first SBL Grand Final, where they lost 72–47 to the
Wanneroo Wolves. Between 2008 and 2015, the women's team only missed the finals once. In the
2019 season, the men's team recorded their most wins in a season with 13, making the finals for the first time since 2012 behind
league MVP,
Joshua Braun. In
2021, the SBL was rebranded as
NBL1 West. ==Accolades==
