It is different to the national league competition, the A-League Men, which also happens every year. The Australia Cup has more teams, and it is the only time that A-League clubs can play official matches against lower-ranked clubs, because the Australian soccer league system does not have relegation.
In March 2023, Football Australia announced that they would be launching a women's version of the Australia Cup, the Women's Australia Cup, in 2024. It will be the first women's competition of its kind in Australia and will allow A-League Women clubs to play official matches against lower-ranked women's clubs. The winner will have a chance to qualify for the AFC Women's Champions League.[2]
