A group of women have become multi-millionaires after discovering they are the holders of the $70 million Oz Lotto ticket.

The hunt for Australia’s biggest single lottery winner is over after a group of female friends produced the winning ticket purchased on the Gold Coast.

The women won $70 million in Tuesday’s Oz Lotto draw and have vowed to split it equally.

The syndicate leader said she checked the unregistered ticket on Wednesday morning and was shocked to discover that they had won.

“When I realised we’d won, I just sat there shaking like a leaf,” she said.

The women regularly meet up for lunch and decided to use their loose change to buy a ticket.

“I told everyone on the last occasion to throw in some loose change and I’ll buy a lotto ticket in a big draw before Christmas,” she said.

“I saw Oz Lotto had jackpotted to $70 million so purchased a QuickPick entry.”

She’s not sure what she’ll do with her share.

“My husband told me he wanted to buy a racehorse but I said `It’s not your prize’,” she laughed.

The winning 12-game ticket was bought from a Runaway Bay news agency.

Lotto players still have an opportunity to win big this week with a $40 million Powerball jackpot on Thursday.
