It could be due to the popularity of the AFL Women's competition or because they've finally found a way to move out of the backyard and into a club, but there has been an unprecedented surge in the number of girls and women playing AFL this winter.

For the first time, every one of the nine WA Football League clubs will field a colts, reserves and league women's team this year.

The WA Football Commission's female football coordinator Allana Dickie said the number of secondary schools fielding girls' teams had grown by 44 per cent this year.

While final figures on the number of female footballers enrolled to play at community clubs were not yet available, Ms Dickie said many clubs were fielding new girls' teams.

This would come off the back of big growth in WA in recent years, from fewer than 5,000 female footballers in 2012 to more than 70,000 last year.

"There's definitely been a very big influx of interest," she said.

"To have 16 new secondary teams jump on board, that to me is alarm bells that there's been an impact on the back of this AFL Women's comp."

Suburban club ranks swell

At a grassroots level, clubs like the Coolbinia Bombers in Perth's northern suburbs are seeing their highest ever levels of female membership.

Last year, 50 girls aged between three and 14 played for the club, but this number is looking like it will reach 80 when the suburban football season starts next weekend.

Their coaches are now joking that they have to learn how to manage an interchange bench, instead of knocking on doors looking for girls to join the club.

"They all think they are Patrick Dangerfield or Nat Fyfe," junior girls coach Mark Davies said.

When asked why they chose to play AFL, many first-time players said they wanted to give it a try after many years of kicking the ball down the park or in the backyard with their fathers and siblings.

But others were inspired by both the women's and men's AFL competitions.

"When I was nine, I started following the Fremantle Dockers and I started watching their girls' games," Kyle Ackere, 14, said.

"I decided to do football because I wanted to show that girls can do the same as others," Isabella Hewton, 11, said.

The effects of the popularity of female football are even stretching to the suburban sports shoe store, many of which are reporting a surge in demand for footy boots from girls and women.

In recent years, Athletes Foot at Midland Gate would sell about three pairs a year.

Already before the season has started, they have sold 30 pairs, mostly to primary school girls and women in their late teens and older.

The demand has been so strong that manager, Kim O'Connor, plans to ask manufacturers like Adidas and Nike to produce a bigger and more colourful range of footy boots for women.
