Australia WNBL

Following an exchange of letters with St Kilda coach Bill Palmer, West Adelaide Bearcat coach Ted Powell in August 1980 called a meeting at the Governor Hindmarsh Hotel in Adelaide. Attended by Powell, North Adelaide coach Kay McFarlane and Noarlunga coach Brendan Flynn, at this meeting it was decided to approach three Victorian teams (St Kilda, CYMS and Nunawading) with the idea of forming a home-and-away interstate competition.

The six teams' delegates then met and confirmed the new League at the Town and Country Motel in Sydney, during the 1980 Australian Club Championships. The meeting resolved to form a two-round competition between these teams, to be held in July and August of 1981. The basis for the idea was that many of the top sides in both states wanted a competition that would differ from their standard state leagues, as well as a suitable preparation for the Australian Club Championship, which was held on an annual basis for the top 24 teams in the country. With the formation of the Men's National League in 1979, it was identified that providing more opportunities for the best female players and clubs to play against each other more regularly would develop the women's game.

The competition was formed with the six teams to play a full home-and-away series between all teams, with three games on one weekend, to save costs. The NSW-based clubs of Bankstown and Sutherland paid their own way to travel to Melbourne and Adelaide, where they would play each team once, for double points. Thus, the WNBL was born. Reference.

Also in 1981, the Australian Institute of Sport (AIS) was opened and the men's head coach, Dr Adrian Hurley (who went on to coach the Australian Boomers in the 1988 and 1992 Olympics), contacted the clubs and asked whether the AIS could also participate in the competition to commence later that year.

The nine teams in the inaugural season of the league were the AIS, Bankstown Bruins, Catholic Young Men's Society (CYMS), Melbourne Telstars, Noarlunga Tigers, North Adelaide Rockets, St Kilda Saints, Sutherland Sharks and West Adelaide Bearcats. On 19 June 1981, the competition commenced with the first game played in Adelaide, between the AIS and West Adelaide. The competition was called the Women's Interstate Basketball Conference, with each team paying $25 to be a part of the WIBC – giving a central fund of $200 to conduct the competition.

The inaugural winner was St Kilda, defeating the North Adelaide Rockets 77–58. St Kilda also went on to win the Victorian State Championship and the Australian Club Championship in Melbourne, defeating Bankstown Bruins in the final. St Kilda had three Australian representative players in Tracy Morris, Karen Ogden and Patricia Cockrem. Ogden would go on to become the national league's first two-time Most Valuable Player award winner, receiving the individual trophy in 1982 (the first season for which it was presented) and again in 1983.

In 1982, the competition expanded into another state, with the entry of a Brisbane team. The new revised program saw Victorian teams travelling to NSW and the ACT, NSW teams travelling to South Australia, and South Australian teams travelling to Victoria. The competition also changed its name to the more appropriate Women's Basketball League (WBL). St Kilda repeated its inaugural victory in 1982 with a grand final win over Bankstown. St Kilda's men's team also won the first two NBL titles, which showed the strength of St Kilda at that time.

In 1983, the, Nunawading Spectres led by Robyn Maher, easily defeated St Kilda in the grand final and went on to win nine WNBL titles in 12 years. During the 1983 Australian Club Championships, a workshop was held to discuss women's basketball and from that meeting came the decision to bring together a second tier of clubs to form the Women's Basketball Conference (WBC). There were now 20 women's teams playing in a home-and-away competition, which immediately improved the standard of women's basketball in Australia.

With the NBL riding a sudden wave of popularity, media interest in the women's league was also increasing. Most clubs were recognising the need to promote themselves and the image of the league. Pairing women's games with games of the men's NBL and South East Basketball League (a secondary interstate competition) in double-headers exposed the women's game to a wider spectator audience unfamiliar with the quality of women's basketball.

In 1985, the two women's competitions worked together to improve women's basketball, recognising the need to promote the competitions, as well as the individual clubs and athletes. Hobart won the second WBC title.

When a Perth was admitted for the 1986 Women's Basketball Conference, the two women's leagues combined provided a truly national competition. The Australian Basketball Federation approved the WBL's application to be renamed the National Women's Basketball League and a new era was underway. 1986 was the first year that the WNBL played its first full home-and-away competition. In 1987, Perth sought and was granted a position in the national league, on the basis that Perth paid its own airfares in its first two years.

Following the success of Australian basketball at the 1988 Seoul Olympics, the WNBL appointed Lyn Palmer in the newly created full-time General Manager position. Palmer had just retired after a distinguished playing career with St Kilda, Nunawading and Coburg. Her husband Bill was General Manager of the men's NBL.

In 1989, the WNBL gained its first sponsorship from Pony, one of Australia's leading sporting apparel companies at the time for a reported $258,000. The ABC broadcast the finals series. There were 13 teams in the WNBL for the 1989 season. The Bankstown Bruins changed its name to the Sydney Bruins.

The next few years saw the league continue to grow, with Australia chosen to host the Women's World Championships in 1994.

In 1993, the WNBL teams agreed to contribute financially so that games could be televised on a weekly basis by the ABC. This coincided with the men's Sydney Kings taking over the ownership of the Sydney Bruins, renaming the women's team again, to the Sydney Flames. Coached by Carrie Graf, the Flames became one of Australia's most popular women's sporting teams.

In the early 1990s, the Perth Breakers started wearing the bodysuits that would become synonymous with the women's game in Australia. The Sydney Flames won the title in 1993, gaining back page coverage in the Sydney newspapers - a feat not envisaged in the early 1980s.

The 1990s were dominated by Sydney, Melbourne Tigers, Adelaide Lightning and Canberra. The AIS won its first title in the first summer season of 1998–99, led by one of the best basketballers in the world, Lauren Jackson.

In 1995, Leeanne Grantham (née Christie) became the Chief Executive of the WNBL. Throughout the mid-to-late 1990s, and into the early 2000s, the WNBL brand became the best known women's sport brand in Australia. It was also recognised as one of the top three leading women's basketball leagues in the world.

The ABC televised weekly WNBL games and broadcast the 1994 Women's World Championships, held in Australia. This provided women's basketball the profile required to secure significant sponsorship, enabling the League to continue to build on the WNBL brand.

The ABC continued to televise the league, despite some difficulties in mid-2001, when the ABC contemplated changing its televising of sport. A successful partnership between the WNBL and Netball Australia subsequently saw both sports retained on the ABC. The ABC undertook to increase its coverage by showing Friday night games live on ABC digital television and replays on Saturday afternoons.

The WNBL was very stable with eight teams for a number of seasons, with Tasmania and Northern Territory not represented. In 2006, through the efforts of a strong community focus for women's basketball, Bendigo commenced discussions with Basketball Australia about entering a team for the 2007–08 season. At the same time, Basketball New Zealand had discussions with Basketball Australia about a team from New Zealand entering the next season.

In October 2006, the decision was made to welcome two new teams into the WNBL for the 2007–08 season in Bendigo Spirit and the Christchurch Sirens, who had a number of the New Zealand Tall Ferns players on their initial roster. One of the strategic objectives of the WNBL was to see a second team from the south of Queensland and after studying the feasibility, Logan Basketball Association was successful in being admitted to the 2008–09 season, with the Logan Thunder.

The February 2023 match between the Southside Flyers and the Sydney Flames drew the largest ever WNBL crowd of 7,681.

In June 2024, Basketball Australia sold the WNBL to a consortium co-managed by the National Basketball League (NBL). The NBL assumed operation of the WNBL from April 2025, following the 2024–25 WNBL season.

In May 2025, a new brand and logo were revealed by the WNBL.
