About one third of Australian adults had an entry in last night's $80million Powerball draw.
Powerball tickets expire one year after the drawing date, and unclaimed prize money goes to the state School Aid Fund.
Among last night's victors were 15 division two-winning entries, each taking home $81,533.30.
10, 11 and 12 are among other cold numbers.
Lott spokesman Matt Hart said about one in three Australian adults had an entry in Thursday's multi-million dollar jackpot, but there was no first division victor and the prize jackpots to $100m for next week.
The Lott spokesman Matt Hart said next Thursday's draw had the potential to set a new record of its own.
"We will not only see WA's largest Lotto prize of $50 million smashed, but also the current national record of $70 million", she said. Before their life-changing windfall, the winners confessed to never having won anything more than a chook raffle.
To win the $50,000, the player had to match four white balls numbers and the red Powerball number, the odds of which are 1 in 913,129, according to the statement.
