Born in Sydney, Kay Keavney completed a Bachelor of Arts at the University of Sydney before being employed by the ABC. She was both the youngest person and the first woman to be hired as a scriptwriter by the national broadcaster. In the late 1940s she wrote serials and plays for various networks and production companies but unfortunately most of the scripts of these shows were not preserved. Keavney also adapted many plays for the Macquarie Radio Theatre, and books for the Library of the Air.
Set in the fictional Waratah National Park (NSW), the Skippy series focuses largely on the adventures of a young boy, Sonny Hammond, and his intelligent pet kangaroo, Skippy. Sonny is the youngest child of Head Ranger Matt Hammond. Matt was left a widower in his early forties when his wife Mary died not long after Sonny was born. Other principal characters are Sonny's older brother Mark, Flight Ranger Jerry King (the park's helicopter pilot), and Ranger Clancy Merrick, the teenage daughter of another park ranger.
