A NSW Labor MP is calling for a parliamentary inquiry into children's soccer to expose "the scandalous exploitation of local children and their parents".

The Member for Heffron, Ron Hoenig, first addressed parliament in August this year, after learning that parents in his electorate were paying fees of up to $1100 for children as young as six to play at clubs in the Eastern Suburbs Football Association.

More than 150,000 children aged between five and 17 play grassroots soccer in NSW.

"Football clubs utilising council grounds, which in the past have been community-based [and] run by volunteers, have now outsourced coaching to profit-making soccer academies," he said. "These private academies have infiltrated this children's sport, exploiting parents into paying huge fees under the belief that if they pay, one day their child will play for Manchester United."Mr Hoenig has highlighted the Heffron Hawks as one junior club that has engaged coaching services from a private soccer academy named Soccer De Brazil, where he is aware of children as young as six paying fees of $1100.
