Bulleen-Templestowe Basketball Club (BTBC) was established in 1969. In 1984, BTBC secured a licence to join the
Women's National Basketball League (WNBL), The Boomers were first coached by Trevor Cook, with the initial team including
Michele Timms and
Samantha Thornton. The club first qualified for the WNBL finals in 1989 under the guidance of coach Paul Deacon, and, after progressing to the same stage the following year, missed the playoffs until 1996. In coach Lori Chizik's first season, Bulleen finished third in the regular season before bowing out in the semi-finals. Chizik led the Boomers to the 1999–2000 preliminary final, marking the club's best-ever result to that point.
Cheryl Chambers then took over in 2001–02 and steered the club to two finals appearances, including the 2004–05 preliminary final.
Katrina Hibbert and
Hollie Grima formed the backbone of the Boomers during the 2000s. Hibbert won back-to-back League MVP awards during the 2004–05 and 2005–06 seasons. In 2014,
Deakin University joined as a naming rights partner. In March 2024,
Geelong United Basketball (GUB) and a consortium of local private investors from Geelong expressed interest in acquiring the Boomers' licence after the Boomers' ownership group looked to transfer its licence. Two months later, the license was officially transferred to GUB, with the team moving to
Geelong under a new brand
Geelong United. In the
2024–25 WNBL season, Geelong United finished in seventh place with a 6–15 record. On 1 July 2025, GUB rebranded the WNBL team as
Geelong Venom. ==Home venues==
