A resident of an affluent Melbourne suburb could be even richer as officials try to find the mysterious winner of a $20 million prize.

Four people across Victoria, Queensland and Western Australia each won a $20 million slice in last night’s $80 million Powerball draw.

But one winner is still unaware of their new multi-millionaire status. 

An unregistered player holds a division one winning ticket purchased at the East Brighton Newsagent in Brighton, Melbourne. 

“That means we don’t have any clues to their identity,” The Lott’s Matt Hart said. 

The man who sold the ticket, East Brighton Newsagent owner Sajjad Sadeghi Goorbandi, believes the winner may be one of his regular customers.

“I wish all the best for them, and for my outlet, for the shop, for the area. It’s amazing,” he said.

Brighton residents were also excited to hear the winning ticket was purchased in their neighbourhood.

“I would love to have $20 million,” one said.

“You just wouldn’t know what to do with yourself, would you?” another said.

“It’s amazing. It’s so good it’s from Brighton,” a third said.

Anyone who purchased a ticket to last night’s Powerball draw at the East Brighton Newsagent is urged to check their numbers.

The lucky winner can contact The Lott to begin the process of claiming their prize.

A young woman from Woolloongabba in Queensland, a woman from Mooroopna in Victoria, and a winner from Western Australia held the other three division one winning tickets.
