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 during a 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.
