For decades, South Australia's sportswomen have used car parks and kitchens to change into their uniforms due to a lack of female facilities.

But that could soon change, with the State Government pledging $10 million in the upcoming state budget to build and upgrade female change rooms at sporting clubs across South Australia.

The captain of the state's Australian rules women's team Courtney Cramey said a lack of female facilities was an issue at most of the state's sporting clubs.

"Women's sport's growing," she said.

"It's growing at the top level, which is building participation at grass roots as well.

"In AFL, we have 22 in our team, and 22 girls lining up for one toilet can get quite hectic and can get a bit rushed before game time."

About 150,000 girls and women are registered with sporting clubs in South Australia but many are forced to use male change rooms due to a lack of female facilities.

Treasurer Tom Koutsantonis said significant upgrades were needed to encourage more girls and women to take up sport.

"We want women to get involved in sports. We want them to take part in all our community activities and you can't do that without infrastructure," he said.

"That means we won't see women getting changed out in the car park, women getting changed in the kitchen, women getting changed in places that are very awkward and embarrassing."

Sport Minister Leon Bignell said it would cost about $200,000 to build a female change facility, but Mr Koutsantonis said there would be no limit on the amount one particular club could spend on an upgrade.
