Queanbeyan City Newsagency sells $100,000 winning lotto ticket

They're $100,000 dollars richer but the mystery winner of the lotto Super Jackpot in Queanbeyan has yet to come forward.

The winning ticket was bought from Queanbeyan City Newsagency on Crawford Street but it wasn't registered to a Players Club card and so lottery officials have no way to contact the winner.

Mark Cantwell works at the newsagency and said he was excited to have sold the winning entry.

"We are very, happy, it's been a while so it's great news to hear," he said.

"We have been telling all of our customers to check their tickets as we have a winner in town but they don't know it yet!"

NSW Lotteries spokesperson Elissa Lewis said she was eager to solve the Queanbeyan mystery.

"You may not think it's possible that you are holding the winning ticket, but if you purchased an unregistered Lucky Lotteries Super Jackpot entry from Queanbeyan Newsagency, you're in with a chance!" Ms Lewis said.

Ms Lewis said anyone holding the winning ticket should contact NSW Lotteries on 131 868.

The Lucky Lotteries Super Jackpot prize is now $4.27 million for draw 10187, while the Lucky Lotteries Mega Jackpot is now $5.08 million for draw 1068.
