Mystery winner of $4.8million lottery prize finally found right before Christmas – as she plans a significant life change with the windfall

Australia's newest millionaire has finally claimed her millions after her ticket went unclaimed for days – as she reveals how she plans to spend the money.

Monday's Set for Life draw saw one division one winner, with the woman from Narre Warren, 38 kilometers south-east of Melbourne, taking home the full $4.8 million.

Because the ticket was not registered, The Lott officials were unable to contact the winner and were forced to rely on word of mouth.

The tactic worked and on Friday morning the woman received a life-changing phone call.

'Woohoo! Happy New Year to me! Cool bananas,” she reportedly said when officials told her she had won nearly $5 million.

The woman will pocket $20,000 every month for 20 years until the prize is paid out. Her first purchase will be a new house.

'I had a tough week and felt bad, so this is a great surprise. I will have to leave the festivities until I feel better,” she said.

'I've lived in my house for over thirty years and have thought about packing up and moving to a new house – now it's possible.

'It's time to buy a new house and fix it up a bit. I will also have to do some shopping after Christmas when I feel better.

Her winning numbers were 44, 25, 38, 21, 41, 18 and 39, while the additional numbers were 8 and 34.

TThe final Oz Lotto draw of the year will also be the second-largest prize in Australian lottery history, surpassed only by Powerball's $100 million jackpot in August.
