Australian man accidentally wins Lotto twice in one go

An Australian man has won AU$46 million (NZ$48 million) after accidentally buying the same ticket twice.

The unnamed Melbourne man bought a ticket at Winning Lotteries St Albans, and then accidentally bought another one with the same numbers at Footscray Lottery Centre.

The tickets were for Tuesday night's AU$70 million jackpot, and each ticket won the man AU$23.3 million (NZ$24 million), reports The Daily Mail.

Another winner in Hobart has yet to claim their NZ$24 million prize.

If the man had only bought one ticket, the jackpot would have been split between him and the Hobart winner, but because he bought two he has received two-thirds of the massive prize.

"I play every week. I have always marked my entries but I have never chosen the numbers on anything in particular," the man told The Daily Mail.

"They weren't special before but they are now," he added.

He says he might think about retiring with his winnings, but he has other priorities.

"First, maybe a new home, or a holiday. I'll definitely share it with my family."

The owner of the third winning ticket may not even know they have won, according to lottery organisers The Lott.

"The other entry is an unregistered entry that was purchased at Hobart City Lotto," said a spokesperson for the company.

"We don't have their contact details and someone is going to awaken - hopefully tomorrow - check their ticket, and discover they've won."
