The W-League is the top-division women's soccer league in Australia, run by Football Federation Australia (FFA). The W-League was established in 2008 and was composed of eight teams of which seven had an affiliation with an A-League club. The eighth team was a new entity based in Canberra. The league is currently contested by nine teams. The competition is known as the Westfield W-League through a sponsorship arrangement with the Westfield Group.
Seasons typically run from November to February and include a 12-round regular season and an end-of-season finals series playoff tournament involving the highest-placed teams, culminating in a Grand Final match. The winner of the regular season tournament is dubbed 'Premier' and the winner of the grand final is 'Champion'. Since the league's inaugural season, a total of five clubs have been crowned W-League Premiers and five clubs have been crowned W-League Champions.
From 2012 to 2014, the W-League champion team qualified into an international competition, the International Women's Club Championship.
Brisbane Roar are the current Premiers, having won the trophy for a record-equalling third time. Melbourne City are the current Champion, having won all three Grand Finals, in all three seasons, since their inception to the league in 2015. They are the first team in the competition to win three championships consecutively (2016-2018).

Between 1996–2004 the Women's National Soccer League (WNSL) was Australia's top women's association football league. In 2004 it was discontinued alongside the men's National Soccer League.
After Australia qualified for the quarter-finals of the 2007 FIFA Women's World Cup, head coach Tom Sermanni felt the establishment of a professional league was vital for continuing the development of players. Football Federation Australia established the league the following year. The W-League was initially composed of eight teams: Adelaide United, Brisbane Roar, Central Coast Mariners, Melbourne Victory, Newcastle Jets, Perth Glory, and Sydney FC. Seven of the eight teams were affiliated with A-League clubs, and shared their names and colours to promote their brands. The eighth club was Canberra United.
The W-League's inaugural season commenced on 25 October 2008, with Perth hosting Sydney at Members Equity Stadium. After ten rounds, the regular season finished with Queensland Roar as the top-placed team, becoming the first W-League premiers, and advancing to the semi-finals along with the second-, third- and fourth-placed teams. Queensland faced Canberra in the 2009 W-League Grand Final, defeating them 2–0 to take the champions trophy.
On 13 May 2015, Melbourne City were confirmed to compete in the W-League from the 2015–16 season. The club had a remarkable inaugural season, winning all 12 of its regular season games and winning the Grand Final.
The W-League regular season typically runs from November to February and consists of 12 games per team, with the highest ranked team winning the title of "Premier". The top four teams in the regular season then advance to the single-game knockout semifinals, with the Champion determined by the victor of the Grand Final.
A W-League squad is required to have a minimum of 20 and a maximum of 26 players. Players typically receive a one-season contract, with many playing in leagues in other countries during the W-League's off-season. Due to the W-League's season running during the off-season of several leagues around the world, many foreign players have played for teams in the W-League and vice versa.
In 2015, teams in the W-League had a salary cap of A$150,000. Individual player salaries vary, with one player reporting to The Sydney Morning Herald in 2012 that whilst some players earn $10,000, others earn nothing. In 2014, it was reported that Sydney FC players were paid salaries ranging from $1,000 to $6,000. Players can also earn money playing overseas and may therefore be considered by Professional Footballers Australia (PFA) as professional.
For the 2017–18 season a minimum salary was introduced at A$10,000. The average salary therefore rose from A$15,500 to A$17,400. A salary cap was set at A$300,000.
The 2018-19 season marked the first time that fans would be able to watch every W-League game. All matches will be broadcast or streamed on Fox Sports, SBS Viceland and the My Football Live app. Thursday Night Football was also introduced, meaning 13 stand-alone regular season matches will be played in prime-time and broadcast live on Fox Sports.  The Football Federation Australia (FFA) reached a deal with ESPN+ for broadcast rights to W-League games in the United States. ESPN+ will carry at least 17 W-League matches in the 2018-19 season.  For the first time ever W-League games would be broadcast on Youtube and Twitter in territories without a traditional broadcast partner.
