"I thought I may as well keep it for myself," the woman recalled.
The player scratched off the ticket and revealed it was a $7,765.45 top prize winner.
"I was dumbfounded," she said. "I was so excited. I couldn't believe it. I just sat there completely stunned."
The winner said the ticket very nearly became someone else's good fortune.
"I could have easily put that ticket in someone's Christmas card," she said. "I felt as though it was really meant to be for me."
The woman said her plans for the winnings include taking a vacation to South Australia and sharing with her granddaughter.
