Big queues are expected at Lotto outlets today, with a massive $25 million in the Powerball kitty.
One winner could scoop a total of $26.8 million, once the First Division and Strike prizes are included.
Lotteries Commission spokeswoman Karen Jones expects sales today will be double what they would duringa normal week.
"We always find even though people know it's coming all week, people do leave shopping for a Lotto ticket to Saturday and so we're expecting this afternoon, especially in busy supermarkets, there will probably be a few queues."
If the prize isn't won tonight it then jackpots to $30 million, and becomes a 'must be won' draw.
