Shan Benson wrote numerous documentaries for television and film, especially in the post-war period: titles include Farming for the Future (1949) and Bee-keeping on the Move (1950). He was also strongly associated with the Catholic church: his works in that area included Fishers of Men, a series of twelve radio plays on the twelve apostles and No Mean City, a play exploring a man's loss of faith in atomic-age Melbourne. He was later the president of the Australian Writers' Guild.
He was married to journalist Sheila Clancy.
