The lucky Roxby Downs Lotto winner has stepped forward and claimed their prize.
The winner who wished to remain anonymous had been working long hours when the draw occurred.
The lucky local didn't realise he had won until last Thursday.
According to the winner, he's "too shocked" to have given any thought as to how he might spend his $1.35 million prize.
The winning ticket was sold at Roxby Downs Newsagency.
The winner shared the $19 million Lotto Megadraw prize with 13 other players from around Australia.
