One very lucky punter could take home a record-breaking Lotto haul with $100 million up for grabs in the largest prize pool in more than a decade.
Up to a third of Australian adults are expected to buy a ticket for the bumper Oz Lotto draw before sales close ahead of the draw late on Tuesday.
The jackpot is the largest for the lottery since 2012, when the prize was split between four division one-winning entries.
However, if the full prize goes to a single person - the odds of which are more than a million to one - they would become Oz Lotto's richest winner.
Khat McIntyre, from lottery provider The Lott, said whoever won the prize would receive a call they would remember for the rest of their lives.
"Reactions we often hear when breaking the life-changing news include screams of excitement, cries of joy or bursts of laughter," she said. Sixteen lotto winners scooped up more than $323 million in the last financial year.
An Adelaide man became Australia's largest-ever individual lottery winner in May, when he took sole claim to a $150 million Powerball prize.
It was the third-largest lottery prize in Australian history, behind a $200 million Powerball win shared between two people in February and a $160 million jackpot in 2022 split between three ticket holders.
Gambler's Help puts the chance of taking the first-division Oz Lotto prize, by getting all seven numbers correct, at less than one in 62 million.
That compares to an estimated one in 1.2 million chance of getting hit by lightning in any given year, according to US researchers.
