John Clarke's daughter Lorin Clarke has described to her father's beloved ABC audience what happened in the Grampians in Victoria on Sunday, when the comedy veteran died suddenly while hiking with his wife.

Speaking for the first time since his death on Jon Faine's morning radio program, Ms Clarke said while her father's death had come as a shock, he was doing what he loved with her mother, in the company of a qualified medic who couldn't possibly have saved his life.

"On the weekend he was doing what he and my mum do most weekends, which is go and find some nature, and just go and exist in it, and look at it, and take photos of it," she told Faine's ABC listeners.

"There are not many family photos of dad because dad was always behind the camera ... The first pictures that little kids started drawing of John, he had a camera: it was like two arms, two legs, a head and a camera.
