A Geelong west couple is $685,000 richer after a lucky mix-up in Saturday night's Tattslotto.
The lucky punter accidentally submitted two entries for the weekend draw and scooped two first division prizes worth $685,381.44, News Ltd reports.
The mystery woman says she has dreamed of winning for many years.
She plans to pay off bills, buy a new car and go on holiday with her winnings.
The winning tickets were bought from Murphy's News Agency in Geelong west.
