Frank Kemmler, 70, from Adelaide, told his family they were going on a holiday after he learnt he had won thousands of dollars in a Lotto draw.

“It was certainly a nice feeling when I checked me numbers,” he told A Current Affair on Friday.

“I rang the family. I said, ‘pack up, we’re going on a holiday!’”

The excitement quickly came crashing down when he visited his local Centrelink and was told access to his pension would be cut as his Lotto winnings, paid out every month, was considered a form of income.

“[It] was a bit of a disillusionment. You think you win on the one hand, but they take it away with the other hand,” he shared.

“It was so unexpected, it took me a couple of days to realise I had just been cut off for no reason at all. So much for being lucky.”

Mr Kemmler said he would have taken his winnings as a lump sum but he wasn’t given the option.

The 70-year-old has now been left to pay full price for GP appointments and medication which were previously covered under the pension.

Mr Kemmler’s monthly payments have also now died up. But when he reapplied to receive the pension on December 1, he was told “they were so busy” and he could wait for up to six months to receive the benefits.

“Anybody would think I grew younger, I grew a year older not a year younger,” he said.

He urged Aussies on the pension to be careful if they’re lucky enough to win Lotto as they too could have their benefits cut.

“The pension is not really my main worry, because I’m just trying to stop other people from falling into the same trap,” he said.

“These people that are buying these [lottery] tickets, there’s no warning anywhere … to say that you’re going to lose your pension.

“If I’d known then what I know now, I would’ve given the win to my daughter and kept the pension for myself.”

Services Australia told A Current Affair they would work with Mr Kemmler to ensure he is getting the support he is eligible for.
