These competitions comprise both genders, and incorporate four levels of senior competition (men), three levels for women and youth leagues. As a member of the Australian Basketball Association (ABA), the winner of the Big V Championship League gains automatic entry for the Australian Basketball Club Championships against the winners of the other ABA conferences.
The league commenced under the name "the Victorian Women's Conference" in 1987. The men's and women's competitions were run independently until 2000. Until this time the league was known as either the CVIBL (Country Victorian Invitation Basketball League), the VBL (Victorian Basketball League) or WVBL (Women's Victorian Basketball League). In 2004, the member clubs of the league voted to re-brand the entire league structure as Big V going forward.
