One lucky Australian has won $3.3 million but still does not know it.

They hold one of six winning tickets in Saturday’s Gold Lotto draw 4571.

Officials from The Lott have been unsuccessful in contacting the missing winner using the registered details and urge anyone who purchased a ticket at Campbells News and Casket on Ruthven Street, Toowoomba, to verify their ticket.

“I was excited to deliver the life-changing news to the region’s newest division one winner, but unfortunately, when I dialed the number provided, it was disconnected,” stated The Lott spokesperson Anna Hobdell.

“You might not believe you’re the division one winner we are looking for, but if you bought an entry in the recent Gold Lotto draw from Campbells News and Casket and haven’t checked it yet, you might be in luck.”

The winning numbers were 1, 35, 18, 25, 45 and 38, while the supplementary numbers were 4 and 16.

The winner is urged to contact the Lott on 131 868 as soon as possible.

There were six total winners of Saturday’s Gold Lotto; three in New South Wales, two in Victoria and the unclaimed one in Queensland.
