Three lucky WA Lotto players picked up a Division 1 prize of more than $341,880 each in Saturday's draw.
The winning tickets were sold at Bayswater News and Lotteries, Herne Hill Village Lottery Centre and Rockingham Central Lottery Centre.
It was the second time the Rockingham store has sold a Division 1 ticket after it sold a $1 million ticket early last year.
"We are so excited. We just love it when we sell a big winner," Rockingham Central Lottery Centre owner Marie Alexander said.
"Our local customers are always so positive when they buy their Lotto tickets and often share lovely stories about their Lotto wish list, including sharing the prize with close family."
The win cements the Town of Rockingham's new title as WA's Lotto hot spot.
Four Division 1 tickets worth $3.3 million were sold in the area last year.
Five WA Division 1 Lotto winners have shared more than $3 million in prizes this month.
