A couple from Perth’s southern suburbs has won $15 million in last night’s Oz Lotto draw after buying the nation’s only winning division one ticket.

The ticket was sold from Newsxpress Meve in the Perth suburb of Beeliar, where staff today celebrated their first division one win.

Lotterywest spokesperson Pina Compagnone said $15 million was WA’s sixth biggest win, with $30 million the most ever won.

The winning ticket holders, who wanted to remain anonymous, were welcomed into the Lotterywest winner’s room this afternoon to claim their prize.

A Lotterywest media release said the woman who had won planned to use some of the money to help family members.

“We’ve always had a home but my sister and her family never have,” she told Lotterywest.

“They’ve struggled and now we are able to make a real difference and buy their dream home for them.”

The woman said the winnings would also pay for a holiday for her Mum and a close friend.

Ms Compagnone said last night’s result was the third big win in WA in six days.

“Three division one lotto wins started on Wednesday with a $1 million ticket, then someone won just over $1 million on Saturday night and now an incredible $15 million,” she said.

“We are certainly known to have luck in Western Australia.”

Ms Compagnone said there had been 20 division one wins so far this year and $15 million was the biggest.

Newsxpress Meve manager Pat Shepley said the newsagent’s owners were on holidays overseas but had been informed about the win.

Mrs Shepley said none of the previous wins from the newsagency had come close to this one.

“We have had a few small division three wins but this is our biggest,” she said.

Mrs Shepley said the owners could not believe the win had happened while they were away but they were very excited.
