Queensland winner takes out $50 million Oz Lotto jackpot

Officials say the ticket was bought online by a registered player but multiple calls to deliver the good news went unanswered tonight.

"If you see a number of missed calls on your phone, you could be the winner we're trying to contact," The Lott spokesperson Matt Hart said.

"You may not think it's possible you're the division one winner we're searching for, but if you purchased an online entry into this week's Oz Lotto draw that you haven't checked yet, you're in with a chance.

"We're urging all Oz Lotto players to check their entries as soon as possible."

The entry was the only division one winner of the night, making the mystery person the "third-biggest winner of any lottery game so far in 2024".

So far this year there have been 328 division one winners.

Last year, 16 Oz Lotto division one-winning entries across Australia — six in NSW, three in Victoria, two each in Queensland, Tasmania and Western Australia and one in South Australia — collectively won more than $330.8 million.
