The $70 million Oz Lotto jackpot - the biggest in five years - has gone off, with an entry from NSW and one from Victoria taking out $35 million each.
A man from Lithgow was "blown away" when he found out about his win last night, while a six-member family syndicate from north-east Victoria claimed their winnings this morning.
"Oh fair dinkum? You're kidding?! That is the best news I've had in a long time. Hallelujah!" the Lithgow winner, aged in his 50s, said when told of his win.
"It goes without saying I'll be helping the kids out and I'm sure my retirement plans will be fast-tracked."
Following the announcement, the Victorian winner who purchased the ticket online, was urged to come forward as their contact details were incomplete.
This morning the Victorian woman made the call, excited and out of breath exclaiming "Oh my god!" while surrounded by her family.
She said the six families who would benefit from the winnings had discussed all morning how they were going to spend their share.
"I know one family member is going to buy a new washing machine and another is going to get a water tank."
Each year about 250 millionaires are made in Australia across the main lottery games - Saturday Lotto, Oz Lotto, the Monday and Wedneday Lotto draws, and Powerball, while Oz Lotto currently holds the jackpot record for $100 million in 2012.
Ahead of Thursday's Powerball winnings set at $80 million, an Oz Lotto spokesman said it was unusual to see two separate jackpots up for grabs in the one week, expecting entrance numbers to spike.
"We've got our regular players and then we've got jackpot hunters who see the figure go to a high amount and think you know what I will give it a go," he told AAP.
In addition to the two division one winning entries, more than 1.17 million prizes worth more than $26.4 million were won in divisions two to seven across Australia.
Last financial year there were 18 division one winners across Oz Lotto, taking home a collective $240 million. Next Tuesday's jackpot is $2 million.
