When he checked his numbers on the MyLotto app, he was "in total shock" when he saw he had won $1 million.
"I can't believe we had no idea that we were sitting on a million-dollar ticket this whole time!" he said.
The man usually plays his own Lotto numbers, but decided on a whim to draw random numbers in September. Despite not having chosen the numbers, the winning ticket still turned out to be strangely personal.
"It was ironic because five of the six winning numbers were family birthdays. It was like I had picked them myself, it was perfect!"
Asked how he intended to spend his belated prize, he revealed his intention to continue life as normally as possible. But the unexpected fortune has given him and his wife more security and peace of mind as they head into retirement.
"We are also really looking forward to helping out our family and going on an overseas trip — it is nice to have that freedom."
The winning ticket was purchased from the Drury Lane Lotto Superette in Drury.
