Someone in Melbourne is walking around not realising they have become a millionaire. Three winning Tattslotto tickets sold in Melbourne over the past fortnight are still waiting to be claimed.

The three tickets, worth a total of more than $2.5 million, were bought by registered customers. Unluckily for these winners, Tatts Lotteries have no way of contacting them with the news which could change their lives.

Tickets to the two biggest prizes were sold in Croydon and Cairnlea, and are worth over $1 million each. They were drawn on Saturday 11 June. The third ticket, bought in Lalor, is worth around $466,000. Victorians have had a lucky streak in recent years, with an unidentified person raking in a whopping $20 million Powerball jackpot in February.
