Olive and Eva was a musical duo who put out the first commercial release in Australia by an all Indigenous act. Olive McGuiness and Eva Mumbler, née Bell, were cousins who in 1955 or 56 recorded four songs, all written by Grace OâÂÂClerkin, which were released by Prestophone Records. In 2019 the recordings were added to the National Film and Sound Archive of AustraliaâÂÂs Sounds of Australia collection.
