The woman, who is from Leichhardt in Ipswich, was the only division one winner in the draw.

She was left speechless when a lotto official contacted her this morning.

“Oh my god! Oh my god! You’re joking?” she said.

“How does this happen? Oh, my goodness. I don’t know what to say.

“I’m shaking. Thank you so much.”

The woman, who doesn’t buy a ticket every week, said she had only won “small amounts like $11” previously.

But she said she knew what she was going to do next.

“I’ll be seeking financial advice right away,” she said.

“I can pay off my children’s mortgages, and I might finally take a holiday. I haven’t had one in years.

“My passport must be expired. I’ll have to get it renewed.”

The woman bought her ticket on The Lott website. The winning numbers were 11,7, 21, 17, 9, 13, and 24, with the Powerball number 11.
