'Why are you calling this late?' Woman answers $100 million phone call

She had just won $100 million as the only division one winner in the Oz Lotto jackpot on February 4.

"It's 10pm here and when I saw multiple missed calls, I thought, 'Who would be calling me at this time?' I was worried something was wrong!" the unnamed woman said.

"I still can't believe it. I only treat myself to lotteries when there's a big jackpot, and I saw $100 million on offer in Oz Lotto and decided to give it a go," the Elizabeth Hills woman said.

The windfall means the woman is the biggest individual Oz Lotto jackpot winner in Australian history with the numbers 3, 34, 35, 26, 44, 39, 36 with supplementary numbers 5, 45, 6.

The winner said the money would change her life forever.

"I love my job, but I won't need to work seven days a week anymore. It's actually really nice to think that I won't need to work," she said.

"I'll finally be able to buy a place of my own. It's so exciting. I'll start treating myself more. I'll go on some holidays!

"I probably won't sleep tonight. I'll have to check again in the morning to make sure I'm not dreaming."

In the year to July 2024, more than $323 million was won through Oz Lotto division one wins in Australia.
