Queenslander wins $55 million
A lucky Queenslander has scooped the entire $55 million in Powerball on Thursday night.
Tatts Group Lotteries spokeswoman Elissa Lewis urged customers who bought an unregistered entry to check their tickets as soon as possible.
"For the mystery ticket holder who has won the entire $55 million division one prize, when they discover their life-changing windfall it will be a moment they will never forget," she said.

"If you discover you're holding one of the division one winning tickets – please keep it in a safe place and phone Tatts Group Lotteries on 131 868 to start the process of claiming your prize."
Ms Lewis said the jackpot was the second largest win on a single ticket in Powerball history, with the record set by another Queensland ticket.
The record for the largest win was set in January 2016, when a ticket bought by grandparents from Hervey Bay won $70 million.
"It is rare, but Queensland seems to have come up trumps when it comes to having those big wins," she said.
"It is also the fourth largest Powerball jackpot in Australia's history, with the current record standing at $80 million, which was set in July 2009," she said.
Ms Lewis said there was no indication when there would be another large jackpot draw.
"Lotto's a random game of chance, and jackpots have a tendency to jackpot at intervals that we can't ever predict," she said.
The winning numbers drawn on Thursday night were 36, 8, 23, 39, 31 and 6 and the Powerball was number 15.
