The third biggest lottery winner in Australian history may not even know they're a multi-millionaire, lottery officials say.
A single winner in Queensland swept the entire $100 million Powerball jackpot but was yet to come forward and claim the prize.
Lottery officials tonight revealed the winning numbers in Draw 1475 were 16, 24, 11, 4, 10, 18 and 23 with a Powerball of 6.

It's the largest lottery jackpot in nearly three months and the sixth largest ever offered.
The Lott said an unregistered winning entry bought on Brisbane's northside, which was not part of a syndicate, took the whole division one prize but had yet to claim it as of about 9.30pm.
"Someone has become an overnight multi-millionaire but possibly doesn't know it yet" The Lott spokesperson Anna Hobdell said.
"We can't wait for them to discover this winning news."
The mystery sparked calls for everyone living in the city, or visitors who bought a ticket while in town, to check their entries in case they were $100 million richer.
"It's a great reminder to players of the importance of registering your tickets to a player card or online account so all of their prizes are secure, and they can be contacted directly with the good news of a big win," Hobdell said.

Ten division one entrants took home more than $188,600 each.
Thousands of Australians were expected to buy a ticket every single minute today, with up to half of all adults trying their luck.
"This is the time when office chatter turns into work syndicates, and everyone becomes a dreamer, plotting how they'd spend a share of the phenomenal $100 million prize," the Lott spokesperson Anna Hobdell said earlier today.
"The last time we saw a $100 million Powerball draw was in May when, the peak of sales was at 6.44pm on the day of the draw when more than 7980 tickets were sold in a single minute.
"On that occasion, the prize wasn't won and it jackpotted to $150 million, which delivered Australia's biggest individual lottery winner – an Adelaide man."
