Football New South Wales is making the case for more funding after a 34 per cent increase in registered players, dubbed the 'Matildas effect'.

At the end of February, more than 25,000 more new players were signed up to play compared to the same time last year.

The fastest growing membership group is women and girls.

Football NSW chief executive John Tsatsimas said while clubs were thrilled with the 'revival' of soccer in Australia, they needed support to make sure the infrastructure can keep up. 

"It's certainly been outstanding in terms of the response to the World Cup," he said. 

"The challenge for us is to put everyone on a pitch at the same time. 

"There's only 24 hours in the day … so we need lights, we need infrastructure, and rain does come which stops the games."

Female player registrations have increased by 23 per cent so far this year and they now make up almost 30 per cent of all players.

Among those are Sydney teenagers Lily Carter and Niamh Lynch, who joined Maroubra United FC in Sydney's east after watching the Matildas in the World Cup last year. 

"I didn't really think girls in soccer was a big thing until I saw that," Lily said. 

"Seeing that atmosphere of both men and women supporting the Matildas… it was just really inspirational."

Mr Tsatsimas said it was critical to support surging female participation.

He said some clubs had limited infrastructure, including a lack of female toilets. 

"We need to make sure... the next group of girls coming through — the future Matildas – are motivated and encouraged," he said.

"Ease of access to facilities will allow that to happen so that we are at the top of the game on an international level."
