WA's newest Lotto multi-millionaires have been found.
A couple from Perth's southern suburbs have claimed their $15 million OZ Lotto windfall from last night's draw.
The regular Lotto player only checked her winning ticket this morning.
"I kept double checking the numbers and couldn't stop pacing up and down the hallway," said the woman.
"My partner had left for work and when I finally got through to him, I asked him to sit down. Then I said I've got a full line of numbers on OZ Lotto!" she said.
The celebrations for tonight include the couple's usual Wednesday home-cooked dinner because the meat for the meal had already been thawed.
"I was thinking about picking up a cleanskin to go with tonight's meal but now I can upgrade to a label," the woman said.
"We've always had a home but my sister and her family never have. They've struggled and now we are able to make a real difference and buy their dream home for them," she said.
"We also want to set up an education fund for my sister and brother in law's children and make sure they are okay for the future," she said.
The winner said her Mum and a close friend will enjoy a special holiday as well.
"I want them to have a wonderful time together, they deserve it."
The multi-million dollar prize will "significantly" top up the couple's superannuation and pave the way for early retirement.
Then they plan to pursue hobbies and volunteer in the community.
A further 51,819 other WA players collected an OZ Lotto prize tonight in the draw's other Divisions.
Lotterywest encourages all players who may have purchased a ticket in the draw to check them as soon as possible for the winning numbers 35, 5, 22, 27, 17, 31 and 29
The record for the State's largest Lotto win sits at $30 million which has been won three times – in October last year, in 2007 and in 2001.
