Winners from opposite sides of the country will share the spoils from Tuesday night's $50 million Oz Lotto jackpot.
But lottery organisers say the new millionaires, from Queensland and Western Australia, might not even know yet.
The winning numbers in Oz Lotto draw 1458 on Tuesday, January 25, 2022 were 17, 31, 22, 11, 26, 36 and 4. The supplementary numbers were 16 and 6.

The Lott spokesperson Matt Hart said repeated attempts to call the Queensland winner, who bought their ticket at The Lott website, had been unsuccessful.
"I was ready to confirm Oz Lotto's newest division one winner straight after the results of tonight's draw were known, but sadly whenever I called the number provided, it just rang out and went straight to message bank," he said.
"If you see a number of missed calls on your phone, you could be the winner we're trying to contact.
"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."
Lotterywest will be getting in contact with the Western Australian winner or winners.
Another 892,135 ticketholders won prizes across divisions two to seven, collecting more than $18.8 million.
