Check your tickets! Mystery Australian scoops $50MILLION lottery prize - but they don't yet know it

A lucky Australian has won a $50million Oz Lotto jackpot... but they don't know they've scooped the big prize just yet.

The new multi-millionaire, from south east Queensland, bought their ticket online and matched all seven numbers. They have so far failed to answer calls from lottery officials.

The winning numbers were 1, 2, 4, 18, 28, 37, and 47, with supplementary numbers 11, 24, and 27. 

'If you see a number of missed calls on your phone, you could be the winner we're trying to contact,' The Lott spokesperson Matt Hart said. 

'You may not think it's possible you're the division one winner we're searching for, but if you purchased an online entry into this week's Oz Lotto draw that you haven't checked yet, you're in with a chance.

'We're urging all Oz Lotto players to check their entries as soon as possible.'

It comes a week after a woman took home a $20million Powerball prize - despite initially thinking she had only won $20,000. 

'I looked at [the ticket] and then ran to my family and said, "I've won $20,000!",' the woman from Gladstone in New South Wales told officials from The Lott.

'They looked at it and then looked at me and said, "No you haven't. You've won $20million!"'

The woman said she would have been happy to have won a $20,000 prize, but is now 'in fairyland' over the life-changing win.

'I still can't believe it,' she said. 'I keep thinking I'll wake up and I'll be back in reality.'

She broke down in tears when asked what she would do with enormous prize, telling lottery officials she had been waiting on 'one of (their) calls for years'.

She plans to buy a house and travel around the world with her winnings.
