An Australian Lotto winner has scooped a £43million jackpot but officials can't call to congratulate them because they didn't provide their full contact details.
The $80million mega win is the biggest prize on record in Australia's southern state of Victoria, and the third biggest in the country.
A lotto spokesperson said: “Imagine going to bed tonight not knowing you’ve just won $80million?
"That’s the reality for one Victorian player after scoring division one in tonight’s Powerball draw!
The winner made an online entry but failed to fill out all their details, meaning officials haven't been able to "make a mind-blowing phone call to them".
Lotto are encouraging Victorians to check their entries as they could be sitting on a cool £43million.

“While we are unable to confirm the win with tonight’s winner, we can guarantee that when they discover the news, it’s sure to be met with a hefty mix of shock and excitement,” the spokesperson said.
“In addition to seeing the massive $80 million prize land in their bank account, this player also shares the title of Victoria’s biggest individual lottery winner and Australia’s third-biggest lottery winner.”
The lucky individual swept the drawn with a landslide selection, securing the hefty prize by guessing all of the numbers and the powerball.
One in four Australians bought a ticket for the draw.
