A mother from western Sydney has been revealed as the sole winner of last week's $12 million Powerball jackpot.
The Merrylands mum said she only checked her unregistered ticket last night, two days after the jackpot was drawn, after seeing a post on Facebook.
"We were getting ready for bed last night, and it said on Facebook that someone bought the winning ticket in Greystanes but haven't claimed it," the mother, who wished to remain anonymous, was quoted as saying in a statement from Powerball.
"I thought 'Oh my goodness, maybe it's me? That's when I went and checked my ticket.
"I got someone to read out the winning numbers and I was shaking as I was looking at my ticket and marking each number off.
"It was just shock. It's surreal. It's completely surreal. "We had to wait until we fell asleep; we couldn't just go to sleep.
"We had a couple of wines last night, and bacon and eggs this morning to celebrate!"
It's the first time an Australian has won a $12 million Powerball prize.
Because her winning entry was unregistered, NSW Lotteries officials had no way of contacting her to break the news.
In the 12 months to June 30, 2019, 10 Powerball division one winners across Australia pocketed more than $398.5 million in prize money.
A Sydney healthcare worker had previously held the record for winning the biggest individual Powerball prize, after taking home $10.75m in January.
Greystanes Centre Newsagency employee Pitou Hong said he was thrilled to know his store had sold the winning ticket.
"We've been so excited to have sold this winning entry and to know that one of our customers is $12 million richer," he said.
