An Australian man who won a $1.5 million lottery prize said the ticket spent five weeks stuck to his refrigerator door before he discovered he was a winner.

The Katherine, Northern Territory, man told officials he bought a 50-game QuickPick entry for the May 5 TattsLotto drawing at Katherine Exposure Photographics and he later heard someone in the area had won, but he didn't even consider that it could be him.

"I had the ticket on the fridge at home the whole time," the man said.

He said the ticket was on his refrigerator door for about five weeks before he took it down to check the winning numbers for the drawing: 34-28-22-42-45.

"I downloaded the results online and I started going through the ticket and then I saw I had all six numbers in a row," he said. "I only realized how much the prize was today -- I wasn't sure if that prize was shared or whether I got that full amount."

The winner received $1.5 million after splitting the jackpot with one other winner.

"Some of it will get used on things we need, but the rest will make a nice little nest egg for our future," he said. "The win won't stop me from entering TattsLotto again. I'll definitely hold onto these winning numbers!"
