The Wantirna Jetbacks Basketball Club was formed by a merger of the Waverley Jets and the Waverley Redbacks in the Waverley Competition in the early 1980's. The club competed as the Waverley Jetbacks.
As the Waverley area "grew up", younger players became hard to find so the Club approached the Knox Gardens Primary School and formed 11 boys and girls teams.
The club originally played half its teams in the Waverley Competition and half in the Knox Competition. As the club grew in size and the players increasingly came from the Knox area, the Club moved all its teams to the Knox Competition and changed its name to the Wantirna Jetbacks.
Wantirna Jetbacks boast over 30 Junior Domestic teams in the Knox competition.
