Women's Australian rules football (in areas where it is popular, known simply as women's football or women's footy or women's AFL), is the female-only form of Australian rules football, generally with some modification to the laws of the game. The first Australian rules football matches involving women were organised late in the 19th century, but for several decades it occurred mostly in the form of scratch matches, charity matches and one-off exhibition games. The first all-female matches began early in the 20th century, and regular competition first emerged after World War II. State-based leagues emerged between the 1980s and 2000s: the first was the Victorian Women's Football League (VWFL) formed in Melbourne in 1981, with others including the West Australian Women's Football League (WAWFL) formed in Perth in 1988 and the South Australian Women's Football League (SAWFL) formed in Adelaide in 1991. The AFL Women's National Championships were inaugurated in 1992. Women's football was professionalised in the 2010s with the establishment of a national league, AFL Women's, that commenced its inaugural season in 2017, with eight teams formed by existing Australian Football League (AFL) clubs: all 18 AFL clubs have fielded women's teams in Season 7 (the second season of 2022). Women's Australian rules football is the most played and watched code of all-women's football in Australia: with more than half a million players, it has surpassed all other football codes in players, including soccer which was once far more popular. The highest level of semi-professional competition, the AFLW, attracts a large audience of more than one million attendees and over two million viewers, and has managed to maintain its high levels of interest despite moving to primarily ticketed and subscription broadcasting models in 2021. The AFLW competition is the most attended women's football competition in Australia, and one of the most popular women's football competitions in the world. With an average attendance in 2019 of 6,262 a game, it has the second highest of any domestic women's football competition. Its record Grand Final attendance of 53,034 for the 2019 AFL Women's Grand Final is also the current record for Women's Australian rules football. Women's Australian rules has also grown rapidly outside of Australia since the 2000s: the Women's International Cup has been run since 2011, and players from around the world have made it to the highest level of the sport, including Laura Duryea, Clara Fitzpatrick and Cora Staunton
