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.
