Three groups of people have won more than $600,000 after winning the division one prize in Saturday's Lotto draw.
One of the winners has yet to claim their prize of $663,112 after they bought their ticket at Newstime Lottery Centre in Perth.
The ticket was one of two winning tickets sold at the store. The store also sold a winning ticket to a 10-member syndicate which has claimed their winnings.
A married couple from the Perth Hills also claimed their prize after buying their ticket at Centrepoint Lottery Centre and News in Midland.
The couple had been playing the same numbers for the past 30 years before their win on Saturday.
"We were so stunned and surprised when we realised we had finally cracked it," the couple said in a statement.
"We are looking forward to sharing the prize with our children and grandchildren and also making some donations to local charity groups."
The weekend wins bring the tally of WA division 1 Lotto winners to 83 for the year. The winners have shared in prizes worth almost $175 million.
