Two Rockhampton grandparents and a mystery Melbournite must have been very nice this year, because Santa has granted them the ultimate Christmas wish in the form of a winning Powerball ticket.
The $100 million prize pot is to be split between the Queensland couple, who had registered their ticket, and the Victorian winner who may not even realise they hold the winning division one ticket, purchased from a Tatts outlet in Darebin.
"You're joking?!" the winning grandmother said as she was told the news of their $50 million windfall in a phone call from The Lott immediately after Thursday night's draw.
"I expected you to ask if we have solar panels, not to tell us we've just won $50 million... I'm in a total state of shock.
"There's going to be a few more prezzies under the tree on Christmas day."
She said the couple were looking forward to being able to help the family, though she wasn't sure they would believe the news.
The Lott officials are waiting for the Victorian winner to check their ticket and come forward before the prize claim process can start.
The winning numbers were 22, 10, 4, 31, 1, 26 and 9. The Powerball number was 14.
"We're encouraging all City of Darebin residents and visitors to check their entries, because you may just discover you've won an exhilarating prize set to change the course of your future," said The Lott's Anna Hobdell.
"We can't wait to unite this mystery winner with their $50 million prize and have that incredibly special conversation about what their future might hold."
Ms Hobdell said it was a timely reminder for players to register their lottery tickets, so they could be more easily contacted in the event of a win.
