A Melbourne man is taking home $46 million after winning division one in Oz Lotto – twice.

The St Albans man had forgotten he had two entries in Tuesday’s $70 million draw, each marked with the same numbers.

“I just checked my entry online and I think I know what you’re about to tell me,” he told officials, who called late on Tuesday to alert him to his double bounty.

“I’m speechless. I can’t believe it.”

Each of the three winning first division entries in Tuesday’s draw takes home exactly $23,333,333.34.

The Melbourne winner said both of his tickets had the same marked numbers, which he’d been playing for 30 years.

“I play every week. I have always marked my entries but I have never chosen the numbers on anything in particular. They weren’t special before, but they are now,” he said.

The man had knocked off work when he discovered his unusual win.

He said he was planning to share his windfall with family, but had to think about what to spend it on.

“I might think about retiring. First, maybe a new home or a holiday,” he said.

Meanwhile, the third first-division winner is yet to come forward. The winning ticket, which was unregistered, was sold at Hobart City Lotto in the Tasmanian capital.

The Lott spokesperson Bronwyn Spencer urged Hobart residents and visitors to check their tickets.

“Imagine discovering you’re a midweek multimillionaire,” she said.
