A teenager who won a million dollars in a fishing competition has promised to repay a man he stole two vehicles from three years ago.

Keegan Payne was questioned by Sky News Australia host Peter Stefanovic about claims the teenager and his friends had in the past stolen a Polaris Ranger and a Polaris quad.

He admitted to the incident and apologised to those impacted.

Bob Cavanagh, the victim of the incident, had employed the teenager at his Katherine mowing business about four years ago.

Despite the incident, Mr Cavanagh said he was thrilled to learn Mr Payne claimed the million-dollar fish.

“I’m having a meeting with him and his father next week. We will sit down, and I will just see what he wants to do,” he told Sky News Australia.

“I did suffer a significant financial burden, and we will talk about what he wants to do.”
