List of NBL1 West champions

The champion teams of the NBL1 West, formerly the State Basketball League (SBL), are determined annually by a grand final weekend hosted by Basketball Western Australia.

All grand finals have been played in a one-game championship decider, except in 1995 when a best-of-three series was used.
