A mystery WA Lotto player is over half-a-million richer after scooping part of the division one prize overnight.
The winner, who purchased their ticket from Hutton Street Lottery Centre and Newsagency in Osborne Park, has scooped a share in the nearly $4 million prize.
The lucky winner takes home $658,047.71, and was one of six division one tickets across the nation.
The winning numbers were 30, 19, 43, 18, 27, 38 with supplementaries 21 and 16.
There were also 15 WA division two winners, who have won a handy $12,159.40 each.
The win comes after one lucky WA punter took home $1 million thanks to Wednesday night's draw. It's understood this ticket has remained unclaimed.
