A Keysborough shopper has struck gold after scratching one of the top prizes of $10,000 on a $1 Treasure Chest Instant Scratch-Its ticket.

But who the winner is, and how they will spend their $10,000 loot, will forever remain a mystery as they have chosen to remain completely anonymous and celebrate in private.

The winning Instant Scratch-Its ticket was purchased at Keysborough Lucky Lotto, Kiosk 1, 211-215 Chapel Road, Keysborough.

Owner of Keysborough Lucky Lotto Wendy Nguyen recounted the moment the shopper discovered their win in store.

“The winner came in and bought some Instant Scratch-Its and scratched them right in the store,” she explained.

“They won $3 on one of them and said to me ‘What do I do now Wendy?’ so I gave them three of the same ticket they had just scratched and they won on the second one.

“They said ‘Wendy! Wendy! Can you count these zeros for me?’ so I counted one, two, three, four zeros!

“I told them ‘Oh my god! You’ve won!’ – It was so exciting! We are so happy for our customer!

“We wish them all the best – they haven’t been in again since so I hope they are off on a holiday or doing something fun!”
