A NSW farmer got lucky when he captured possibly Australia's "greatest snake-catching raptor" in the act.

Chris Morey was checking fences on his acreage at Luskintyre, north-west of Newcastle when suddenly, a falcon swooped and grabbed a brown snake.

Mr Morey reckons he’d be lucky to get a photo like it again.

"I was at the right spot at the right time," he said.
