AFLW membership has increased again after its fourth season, with an all-time record of 20,849 members (up 48.9%) signing up.

The majority of the growth came via expansion teams with three new clubs topping the charts in West Coast Eagles (3,318), Richmond (2,656) and St Kilda (2,299).

"In a challenging year for everyone, the clubs worked extremely hard to stay connected to their members and in turn the members supported the game in a way we would never have expected," AFL general manager of commercial Kylie Rogers said.

"On behalf of the AFL and all the clubs, thank you."
