The South Australian woman from Aldinga Beach bought the tickets as gifts for her husband and father.
The family won a division one prize of $2,222,222.23 in the Saturday Lotto draw 3873 drawn on September 1, one of nine division one winning entries.
“I had bought the tickets for my Dad and my husband for Father’s Day while out with my Mum,” the winning woman told SA Lotteries officials.
“I was just at home about to make dinner when my Mum texted me to ask if I had checked my ticket because she had seen on the news that someone had won but they hadn’t come forward yet.
“I just kind of knew for some reason it was me, so I ran and grabbed the ticket and scanned it on the app and saw that we had won!
“I called her back straight away and my Mum thought I was joking at first. My husband and I can be pranksters at times so they didn’t believe us for a while.
In another strange coincidence, the lucky numbers were drawn on the couple’s wedding anniversary.
“The date it was drawn on actually our wedding anniversary and the game number we won on was our lucky number which was three,” the woman said.

“So it seems a bit crazy that it was sentimental things to us, but we had no idea.”
The winning entry was purchased at Campbell’s Newsagency at Morphett Vale.
The ticket was not registered meaning that SA Lotteries officials couldn’t contact the family to tell them the news and waited for them to claim their prize.
“We hear it all the time but never ever do you think it will be you. It’s crazy! We couldn’t sleep – how could you sleep after that!” the winning woman said.
“I had the worst night’s sleep of my life!”
The family plans to save some of the jackpot for their children’s future, pay off their house, make investments and buy a new car. They may also treat themselves to a holiday later on.
