No winner has come forward to claim the jackpot.

The person who won $10 million with a Powerball ticket purchased in Woden is still to come forward to collect their prize, more than a week after their life-changing jackpot.

NSW Lotteries have no idea who holds the unregistered ticket, and said the prize was at this time the largest unclaimed win in Australia. 

The mystery millionaire bought their ticket at The Thistle Kiosk in Westfield Woden Shopping Centre, and owner Graham Barker said customers were curious to find out whose numbers had come up.

 “We've had a great response from our customers who are all very excited and happy for the winner,” Mr Barker said.

“A lot of people have been trying to guess who might be holding that winning ticket – it’s really hard to speculate on … [they] could be on holiday, or could have thrown it away.”

Mr Barker said the $10 million entry was the most valuable ticket he had sold in his 27 years as a Canberra outlet owner.

“It is definitely the biggest win we have had - about two years’ ago we had a $2.5 million [win]," he said.

NSW Lotteries spokesperson Belinda McDougall said the sole division one winner in last Thursday’s Powerball draw may not be aware they are now a multi-millionaire.

“We are encouraging customers who purchased a ticket in Powerball draw 891 in Woden to check their wallets, handbags, pockets, glove boxes, drawers and even on the fridge door for the winning ticket.

A separate NSW Lotteries spokeswoman confirmed the winner had six years from the date of the draw to claim their prize.

“If it is not claimed within six years, with all winnings the intention is that it is returned to players – through dividends, or special draws – anything that happens with that money needs to be approved by the government regulator,” the spokeswoman said.

The winning numbers were 11, 38, 12, 25, 24 and 13, with the Powerball number 7.

The winner can present their ticket at any NSW Lotteries outlet or online.
