Mystery Sydney resident unknowingly $2.5 million richer after scooping Lotto prize

A mystery Sydney resident is walking around some $2.5 million richer after clinching a division one-winning ticket in Saturday night's Lotto draw.

The mystery millionaire cannot be contacted by lottery officials because the winning ticket was purchased by an unregistered player.

All that is known is that the ticket was bought at Broadarrow Newsagency and Tobacconist at Narwee in Sydney's south.

Newsagent owner Mandy Tiaw is urging all of her regular customers to check their tickets.

"I was so shocked when I heard the news that we'd sold another division one winning entry," Ms Tiaw said.

"We've put up posters and we've got balloons everywhere. We've also been sharing the news with our customers and we are hoping our unregistered winner checks their ticket soon."

The ticket was won of four division one winning entries across Australia in Saturday Lotto draw 4155, drawn Saturday 15 May 2021.

For those playing along at home, the winning numbers in draw 4155 were 19, 16, 5, 41, 15 and 20, while the supplementary numbers were 4 and 21.

"It's likely this winner has been going about their day as normal with no idea they've just won $2.5 million!" said spokesperson for The Lott, Ally Ramsamy.
