The Croc Catchers NT: There are more saltwater crocodiles than people in the Northern Territory apparently, and you’d need to be a bit balmy to tangle with these prehistoric-looking creatures. Tommy Nichols is one heck of a croc wrangler and having two fingers snapped off his right hand hasn’t stopped him. He reckons you need speed and guts to survive in this caper. Duct tape helps, too.
