A mystery Queenslander and a 15-member syndicate from Bonnyrigg in Sydney's west have catapulted themselves into Australia's millionaires club after winning $35 million on separate tickets in Powerball's division one on Thursday night.
The major winner of the $70 million jackpot is holding an unregistered ticket in Queensland and has yet to come forward, a Tatts spokeswoman said.
"We have no details about who it is so we're just encouraging anyone who has purchased an unregistered entry to check their tickets," Elissa Lewis said.
"If you think you're holding the winning ticket, keep it in a safe place and contact Golden Casket so we can verify it and start the prize-finding process."
It has since emerged that the ticket was sold on Queensland's Sunshine Coast.
The Sydney syndicate was a system nine, division one entry, involving 15 players. They will each pocket an envy-inducing $2.4 million.
"We will be getting in touch with them as early as we can," said Ms Lewis, who could not divulge more details.
NSW came out on top, compared with other states, in other takings.
Ten punters won division two, taking home $74,000 each.
Another 1.73 million people scooped more modest-sized prizes in the draw in divisions two to eight - from the measly $13.10 division eight payout to $5872 in divsion three.
The $70 million jackpot has so far been the biggest one this year. It is $10 million shy of the history-making Powerball prize drawn in July 2009.
The winning numbers were 32, 8, 5, 40, 19 and 7 - and the Powerball was 12.
About 5 million players - a third of Australia's adult population - were expected to participate in the draw, according to Tatts Lotteries.
