Joynton Ave., Zetland (Sydney), NSW

In 1954 the Austin Motor Company of Australia and Nuffield Australia merged to form British Motor Corporation (Australia) with the Nuffield facility at Victoria Park becoming the group headquarters of the new company. Austin and Morris vehicles were assembled at the facility and subsequently it was to be the design and manufacturing centre for BMC Australia.

By 1969 BMC Australia's parent company had merged with the Leyland Corporation to form British Leyland and a merger in Australia saw the creation of the British Leyland Motor Corporation of Australia. BMC Australia continued to trade as a division of the new company but had been renamed the Austin Morris Division by 1970. The company name was changed yet again in 1972 when it became the Leyland Motor Corporation of Australia, with the Austin Morris Division carried across to the new company. (WIKIPEDIA)
