August 1979: the inaugural season of the National Basketball League commences in earnest.
While alterations have been made to the league over the past four decades and change, the NBL remains Australia's third-oldest continual sporting code, behind only the Sheffield Shield and the Australian Football League.
Several franchises may have reigned supreme over the past 45 years, however, plenty of once-beloved teams have simultaneously fallen by the wayside, including a handful of past champions.
From a smattering of original teams to a destined-to-fail franchise out of Asia, here are the 24 defunct NBL teams.
