A mystery punter has yet to claim more than $670,000 they won nearly seven years ago.

One lucky entry scored the Division One win in Saturday Gold Lotto draw 3867 on August 11, 2018, but the prize has never been claimed.

Now, with just days to go before the deadline, The Lott is making a final plea to players to check their tickets before it is too late.

“This is Australia’s oldest unclaimed lottery prize and time is almost up,” The Lott spokesperson Anna Hobdell said.

The winning ticket, which was not registered, was purchased at Golden Lucky News in Westfield Helensvale shopping centre on the Gold Coast, Queensland.

The elusive winner matched all six numbers to win $671,513.12.

Had the winner claimed their prize back in August 2018 and invested in Gold Coast real estate, it could be worth more than $1.2 million today.

Even tucked safely in a bank, it might have grown to about $850,000 to $900,000, making the forgotten ticket even more heartbreaking.

Now, under Queensland rules, the clock is officially ticking.

If no one claims the windfall by this Sunday, August 11, the money will be redistributed into player promotions and community programs.

Golden Lucky News owner Melanie Zhi said she’s holding out hope for a fairytale ending.

“It’s hard to believe the division one winner still hasn’t come forward after all these years,” she said.

“We’re really hoping someone checks their old ticket — what a moment that would be.”

While many of the shop’s regulars are locals, Zhi said Helensvale’s location means the winner could be from anywhere — including over the border in NSW.

Tickets hide in all sorts of places

From car consoles to bedside drawers, Hobdell said past winners have found tickets in the most unlikely places.

“Our major prize winners have told us that they have found their old lottery tickets in all sorts of places, so be sure to check your car console, your old shopping bags, or even your bedside drawers because you never know that winning ticket might just be there,” she said.

The winning numbers that night were: 1, 23, 8, 15, 44 and 20. Supplementary numbers: 11 and 18.

The Lott is reminding players to always register their tickets to a Members Club account.

“Had this ticket been registered, we’d have paid the prize out seven years ago,” Hobdell said.

“Even if you lose your ticket, we can still unite you with your prize if it’s in your name.”
