Mr Jaber, 20, estimates he threw away everything he earned "chasing that dream of someday winning" before finally managing to kick the habit 12 months ago.
"I make about $50,000 a year, so I pretty much put every single dollar in the machine," Mr Jaber said.
"You just pretty much wanna feel rich, but in reality you go to work to next day with an empty pocket."
Billions were pumped through the gaming venues of western Sydney in the past year alone. It is home to nine of the 10 top clubs as ranked by gaming profit, according to NSW government figures.
After all his own money was gone, Mr Jaber said he chased his losses with "500 bucks here, $1000 there" via payday loans or by borrowing from people on the pretense of paying his rent.
Even wins - which he dubs other people’s lost wages - were just pumped back into the pokies.
"The next day, all of that money’s back in," he said. "I’ve seen it happen; I’ve done it."
Anna*, an Italian-Australian and frequent visitor to her local club, says in the past she has been left with nothing to pay for shopping or bills after losing all her pension to the pokies.
"It was like they were calling me," she said of the machines she estimates to have swallowed up more than $100,000 in 12 years. “I couldn’t control myself and I lose a lot of money.”
Counselling staff at the Italian Association of Assistance, Co.As.It, are helping Anna to manage her ongoing addiction. She has otherwise kept it hidden from family and friends.
"No one knows," she said. "Because in my community, if they know this thing, I’m in the black book."
Anna recommends steering clear of the pokies. It is a sentiment shared by Mr Jaber.
"If you want to win, just work for it," he said. "If you want to lose, that's the place to go."
