The woman has won a total of $107,575,649.08, bumped up beyond the original $100 million mark due to the sheer number of tickets bought.
It’s the largest individual lottery prize ever handed out in Australia.
An official from The Lott called the registered player directly after the draw to break the life-changing news.
Asked how she would spend the money, the healthcare professional said she loved her work and would not retire.
“It will drive me to do more health work for causes important to me,” she said.
“I’ll be sharing it with my family .. I’m not quite sure what to do but of course I will be helping my family.”
The woman said she would donate a “whole slab” to her favourite charity, and would also buy a caravan and do some travel.
‘Is this a trick?’
Initially the winner thought it was a trick – then thought perhaps she had won the tidy sum of $107,000, not $107 million.
“I don’t understand what is going on!” she exclaimed.
“I’ve had such a tumultuous day, so I don’t know where I am and what I am doing!
“I don’t understand – is this actually real?
“I don’t believe it! I don’t believe it! Is this a trick?”
When confirming the news on Thursday evening, the winner initially revealed she thought she had won $107,000.
“Oh my god, $107,000! That’s amazing!”
“Wait – are you telling me I’ve won $107 million!? Oh my god! That is just so much money!”
The lucky winner is a regular player who bought her 12-game marked entry online Wednesday, choosing random numbers.
“I’m not sure how I’ll be able to sleep tonight, but for now I”m going to go have a cheap glass of chardonnay,” she said.
The winning numbers
The winning numbers drawn were 4, 11, 18, 20, 22, 26, 33 and the Powerball number was 9.
Second prize of $1.89m has been shared by 20 winners, each receiving a payout of $94,792.
The draw was delayed by more than half an hour, sending impatient ticket holders into a social media frenzy.
Last week Powerball punters experienced a similar delay due to technical glitches.
