A couple from Baldivis, who purchased their Saturday Lotto ticket online, were in for a surprise when they discovered that their ticket matched the numbers for a Division One prize in last Saturday's Superdraw.

The couple claimed a share of the $2.5 million prize pool, and it was one of three winning tickets sold.

The couple's reaction to the news was memorable, with one of them admitting that they had to Google how Lotto works to ensure they had really won.

When they shared the news with their partner, she was so overwhelmed that she felt like vomiting.

The couple, who bought their first home last year, have decided to use their winnings to pay off their mortgage and take an overseas vacation to celebrate their good fortune.
