Communities across NSW have lost a collective $5.46 billion to club poker machines in just a year, the NSW Greens say.
The party said its analysis of Liquor and Gaming NSW data for the year ended August 2016 showed the biggest losses occurred in some of NSW's most disadvantaged areas - with Fairfield in Sydney's west topping the state.
More than 10 per cent of annual average income was lost to poker machines in Fairfield compared with just 0.65 per cent in the eastern suburbs of Waverley and Woollahra, the Greens data showed.
The losses were calculated from the turnover of local machines, taking into account the regulated average 90 per cent return of profits to players.
But Greens MP Justin Field had to buy the data and said it should be publicly available.
"Even purchased data aggregates poker machine losses so people can't identify which venues are having the greatest impact on local communities or businesses," he said in a statement on Wednesday.
"If the minister can't or won't do the right thing, the Greens will purchase this data, analyse it and make it available so the community can have a more informed discussion of the harm caused by poker machines across our state."
