Football Federation Australia will push for a big funding boost for junior and amateur soccer in NSW after a report claimed the grassroots level of the sport contributes more than $417 million annually to the state economy.

The report, to be released on Monday, says while the sport is of a significant size, a lack of facilities and general infrastructure is severely hampering it outside the elite level across the country.

Football Federation Australia chief executive David Gallop said the figures show the sport deserves a greater share of government funding, particularly with the NSW state election looming.

"If we extrapolate this NSW data to a national level we can see that grassroots football contribution to the economy is delivering just over $1 billion per annum to the Australian community," Mr Gallop said. "It helps demonstrate with hard data why football is the ideal partner to help governments build vibrant communities."

Football's full potential in NSW equates to an economic contribution of about $619 million per annum, the report's authors claim, but the reality is well short of that figure due to demand from players exceeding supply.
