The Argonauts Club was an Australian children's radio program, first broadcast in 1933 on ABC Radio Melbourne. Its format was devised by Nina Murdoch who had run the station's Children's Hour as "Pat". The show was discontinued in 1934 when Nina moved to Adelaide.[1] The format was revived on 7 January 1941 as a segment of ABC's Children's Session and broadcast nationally except in Western Australia where the two hour time difference made a local production more attractive. From 6 September 1954 it was called the Children's Hour, running from 5 to 6pm.[2] It became one of the ABC's most popular programs, running six days a week for 28 years until October 1969, when it was broadcast only on Sundays[3] and was finally discontinued in 1972.[1]
