The mystery winner of a $3.3 million Tattslotto ticket has come forward to collect his prize four days after the draw.

The St Albans man held one of six division one winning tickets, two of which were sold in Brimbank, and in addition to winning division one, took out division three six times, bumping his winnings up to $3,340,539.04.

As the winning entry was unregistered, officials had no way of knowing who the winner was and simply had to wait for him to come forward.

The man, who is in his 40s said he’s known about the win since Saturday night, but had been too busy to collect.

“I’ve known since Saturday night, but haven’t had the time to get it. We’ve been running around, getting organised. It’s been quite a crazy few days,” he said.

“We were just really surprised when we checked the ticket on Saturday.

“When I told my dad, he dropped the phone.  Luckily the phone still works.”

“We’ve been using those numbers for quite a long time. We’ll keep playing for fun – who knows?”

The lucky winner said he plans to continue working and will use the money to set up his family’s future.

“We’re going to buy our first ever house – we’re still renting,” he said.

“We’ll also get some investments to build a portfolio for the future. We want to benefit the family for many years to come.”
