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.

The Lott officials have repeatedly failed to reach the elusive winner on their registered details and are appealing to anyone who bought an entry at the Campbells News and Casket on Ruthven Street, Toowoomba, to check their ticket.

“I was ready to reveal the life-enhancing news to region’s newest division one winner, but sadly whenever I called the number provided, it said it was disconnected,” The Lott spokesperson Anna Hobdell said.

“You may not think it’s possible you’re the division one winner we’re searching for, but if you purchased an entry into the recent Gold Lotto draw from Campbells News and Casket that you haven’t checked yet, you’re in with a chance.”

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.
