A mystery single entry from South Australia has won the $150 million Powerball jackpot - the third-biggest lotto prize in Australian history. 

Lottery officials said the winning entry was bought in-store from a lottery outlet in Adelaide.

The ticket holder or holders were not registered to a card or หวยรัฐบาล online account, so their identity remains a mystery. 

The jackpot had risen to $150 million on Thursday night after no entries scored the division one prize in the previous $100 million draw, prompting the lottery's top prize to roll higher for the sixth consecutive week.

Lottery officials have urged all South Australian residents or visitors who purchased an entry into the draw to check their tickets.

The $150 million was the third-largest lottery prize in Australian history, behind a $200 million Powerball win shared between two people in February and a $160 million jackpot in 2022 that was carved up between three ticket holders.

The odds of a single entry winning the division-one prize are more than 134 million to one - about the same chance as being struck by lightning twice in a lifetime.
