The ticket was unregistered, so officials have to wait for the winner to contact them.
“Tonight’s win is the second-biggest win to land in South Australia in 2024 and caps off a winning year for the state,” The Lott spokesperson Matt Hart said.
“In May this year, the state welcomed Australia’s biggest individual lottery winner, an Adelaide man who pocketed a $150 million Powerball prize.
“Tonight, a mystery player joined the multi-millionaire club by winning $50 million, but they possibly don’t know it yet.”
The winning numbers were 1, 29, 20, 23, 34, 46 and 39, while the supplementary numbers were 42, 43 and 24.
The winning ticketholder is urged to contact 131 868 as soon as they can.
