Second Powerball $50M winner found

A hardworking father from Riverwood in Sydney's south is ecstatic after discovering the Powerball ticket he had been carrying in his wallet for the past two days was worth $50 million.

The shocked Sydney man was one of the two division one winners nationally in Thursday's $100 million Powerball draw.

The other division one winner from the draw was a Melbourne man in his 20s, who discovered his good fortune yesterday morning.

Speaking to a NSW Lotteries official, the elated man expressed his disbelief at his $50 million payday.

"Oh yeah mate, I'm in a bit of shock to be honest!" he laughed.

"It's just been in my wallet the whole time. I'm guarding this ticket with my life.

"I didn't scream at the news. I won't scream until I have it all in my hand!"

He said he will use his windfall to retire early and set his loved ones up for the future.

The man, who wishes to remain anonymous, purchased his winning entry at Broadarrow Newsagency in Narwee.

Owner Mandy Tiaw said was thrilled her customer had come forward to claim his prize.

"That's great to hear the winner has been found," she said.

"I've been telling all my customers we sold the division one winning ticket. I've only had this store for less than two months so it's amazing to have such a big win so soon."
