"Adventure Island" was a joint production of Godfrey Philipp Productions and the Australian Broadcasting Commission, pre-recorded on videotape at the ABC's studios in Ripponlea, Melbourne. It is believed to be the first program made by the ABC in collaboration with an outside production company. Production was usually five weeks ahead of broadcast. It was a pantomime-style series set in the kingdom of Diddley-Dum-Diddley. The show was hosted by Nancy Cato (a cousin of the noted author of the same name) from 1967 to 1968 (her final pre-recorded episodes aired at the beginning of 1969) and Sue Donovan from 1969 to 1972.
