A mystery Port Macquarie lottery player has just discovered they are almost $1 million richer after checking their division one winning Saturday Lotto ticket.

The player held one of the six division one winning entries in Saturday Lotto draw 4143, drawn Saturday, April 3. Each division one winning entry scored $965,635.64.

However, how they plan to spend their windfall will forever remain a mystery as they have chosen to remain anonymous and celebrate in private.

The life-changing 36-game QuickPick was purchased at Settlement City Newsagency

Settlement City Newsagency team member Gail Alshin said it was fantastic to see a division one prize land in Port Macquarie. The region continues to clean-up after devastating floods.

"This is the first time in a few years we've sold a division one winning entry," she said.

"We're so happy to see this prize go to one of our customers.

"We are all so happy for them and hope it's the first of many."

The winning numbers were 41, 1, 39, 31, 38 and 21, while the supplementary numbers were 6 and 43.
