NBL1 West, formerly the State Basketball League (SBL), is a semi-professional basketball league in Western Australia, comprising both a men's and women's competition. In 2020, Basketball Western Australia partnered with the National Basketball League (NBL) to bring NBL1 to Western Australia. NBL1 replaced the former SBL to create more professional pathways and opportunities for males and females playing basketball in Western Australia. As a result, the SBL became the west conference of NBL1.

History

The State Basketball League originated in 1972 as the District Competition. The District Competition was introduced by the Western Australian Basketball Federation (WABF) as an 'elite' competition held on Friday nights, featuring eight Perth-based associations from the prominent districts of Perth, Swan Districts, Tangney/Willetton, Subiaco, East Perth, Cockburn, Stirling, and Claremont. In 1987, plans were put in place to expand the competition and include several country teams. In 1988, it was decided to form a State Basketball League for both men and women, and in 1989 the SBL made its debut season with three new franchises established in country areas: Rainbow Coast Raiders from Albany, Batavia Buccaneers from Geraldton, and Souwest Slammers from Bunbury. Kanyana Kings from Mandurah and Goldfields Giants from Kalgoorlie joined in 1990. In 2017, the SBL shifted to the 40-minute game format in-line with FIBA, with games consisting of ten minute quarters as opposed to the twelve minute quarters under the previous 48-minute format. Due to the COVID-19 pandemic, the 2020 SBL season was cancelled and later replaced by the amateur-based West Coast Classic. In October 2020, Basketball Western Australia and the National Basketball League (NBL) announced a new partnership to bring NBL1 to Western Australia in 2021, with NBL1 replacing the SBL. The SBL was officially renamed NBL1 West and became the west conference of NBL1.

<!-- # Regular season During the Australian summer, teams begin preparing for the upcoming season, as they host try-outs and trial games, reacquire the services of returning players, and scout for overseas imports. By the end of February, most teams have had their imports arrive in Western Australia and begin training with the rest of the playing group. Import players are most commonly recruited from the United States, with each team allowed two 'restricted' players on their roster. While most teams sign two imports, some do choose to fill a restricted player spot with a [NBL](https://bliptext.com/articles/national-basketball-league-australia) or W[NBL](https://bliptext.com/articles/national-basketball-league-australia) player. In early March, the annual SBL Pre-Season Blitz tournament is held at either Warwick Stadium or [Bendat Basketball Centre](https://bliptext.com/articles/bendat-basketball-centre). The tournament is usually held over a weekend and features all 26 teams competing in a number of exhibition games. During the regular season, each MSBL team plays 26 games, 13 each home and away; while each WSBL team plays 22 games, 11 each home and away. Games are played on Friday nights, Saturday nights and Sunday afternoons. Special weekend blockbusters happen every year, such as Easter Round and Anzac Round, with games often being played on Easter Sunday and [Anzac Day](https://bliptext.com/articles/anzac-day). Other special-occasion rounds include Women's Round, Rivalry Round and Heritage Round. Prior to 2017, the MSBL was one of only a few leagues in the world (other than the [NBA](https://bliptext.com/articles/nba)) to use the 48-minute game format. To align the competition with all State Leagues across Australia, as well as the NBL and international events such as World Cups and the Olympics, [Basketball Western Australia](https://bliptext.com/articles/basketball-western-australia) made the decision to have the MSBL play under the 40-minute game format in-line with [FIBA](https://bliptext.com/articles/fiba) for the 2017 season. Every year since 2015, an SBL All-Star day is held on [WA Day](https://bliptext.com/articles/western-australia-day) at Bendat Basketball Centre. In 2019, after four years of North v South (north/south of the [Swan River](https://bliptext.com/articles/swan-river-western-australia)), the league introduced Australia v World for the first time. Other attractions of the day include a Three-Point Shootout during half-time of both the WSBL and MSBL All-Star games. Around August, the regular season ends. Teams are ranked according to their win/loss ratio. If at the end of the regular season, two or more teams have an identical record, then positions are decided on a head-to-head basis. If they cannot be split after that, then for/against percentage is taken into account. # Finals The SBL Finals begins in early August and finishes in early September, with the top eight teams in each competition (WSBL and MSBL) competing for their respective Championship. The first two rounds of the finals structure, the quarter-finals and semi-finals, are played using a best-of-three series. The higher ranked team hosts games one and three (if required), and plays game two away; with an exception being: any playoff series involving Geraldton or Goldfields will be played under the pre-2016 format with the higher ranked team playing away for game one, then home for games two and three. Every year, [Basketball Western Australia](https://bliptext.com/articles/basketball-western-australia) hosts an SBL Grand Final weekend at [Bendat Basketball Centre](https://bliptext.com/articles/bendat-basketball-centre) to determine the champion teams of the WSBL and MSBL, with the WSBL championship game on the Friday night and the MSBL championship game on the Saturday night. All Grand Finals have been played in a one-game championship decider, except in 1995 when a best-of-three series was introduced for both competitions. -->
