Mobil Quest

The quest was founded in 1949 with the stated aim of "bringing to the attention of the public the best vocal talent available in the Commonwealth" The Vacuum Oil Company had an honorable association with classical music in Australia, having supported Opera for the People concerts and broadcasts since 1946.

The contest was run Australia-wide, with contestants first passing an audition conducted by a participating radio station, which then conducted a series of heats to select that station's candidates for the semi-finals. Eighteen winners, three from each State, then competed in Melbourne to select the six who competed for the £1,000 prize at a grand final at the Melbourne Town Hall. The heats were broadcast in the relevant State capitals, and the finals broadcast through all participating stations. Lesser prizes for finalists were, respectively, £300, £100, £50, £25, and £15, later £300, £150, and £50 each for the other three finalists. Each singer who appeared on air received a broadcasting fee and all semi-finalists received an all-expenses trip to Melbourne.

The Mobil Quest radio broadcasts between 1949 and 1956, and the 1957 semifinals, are held in Australia's National Film and Sound Archive.
