A Sydney council where more than $8 billion was put through the pokies in a year is calling on the NSW government to consider banning any more machines being approved in clubs and pubs in the area due to the high risk of gambling-related harm.

Fairfield Council, which is ranked as the most disadvantaged area in Sydney, says the prohibition should also apply to all other areas at similar risk.

It says the state government regulator, the Independent Liquor and Gaming Authority, should consider capping pokie numbers in all "vulnerable" communities where levels of gambling and machine density are high.

The proposals are contained in a submission to the state government's review of the rules for determining applications by pubs and clubs to introduce extra poker machines to an area, known as the Local Impact Assessment (LIA) process.
