Kathleen Carroll was a prolific radio serial and drama scriptwriter. In the 1930s she belonged to a community of writers that staged plays as part of the Chelsea Drama Club in Sydney. In August 1940, the club performed Ten Ways to Get a Man, a comedy with an all-women cast and written by club members Kathleen Carroll, Gwen Meredith and Betty Neville. Gwen Meredith achieved later success as writer of the long-running radio series Blue Hills for the ABC.
Meredith and Carroll approached radio stations for writing gigs and Carroll got her foot into the door with the opportunity to write for Doctor Mac, a long-running series which commenced in 1940. In 1946 Carroll won a prize in a radio theatre contest for her play Small Town which was produced and broadcast. By 1947 she was writing her first serial, Edmund Conquest and the Pirates of the Barbary Coast, and by 1949 Carroll was writing and adapting scripts for Grace Gibson where she was responsible for the hit series Dr Paul and Portia Faces Life.
