British Motor Corporation (Australia) was a motor manufacturing company formed in Australia in 1954 by the merger of the Austin Motor Company (Australia) and Nuffield (Australia). This followed the merger in 1952 of the Austin Motor Company and the Nuffield Group in the United Kingdom to form the British Motor Corporation. Following further corporate changes in the UK in the late 1960s, BMC Australia was absorbed into the newly established British Leyland Motor Corporation of Australia, the name of which became Leyland Motor Corporation of Australia in 1972, and then JRA Limited in March 1983.

Nuffield Organization was the unincorporated umbrella-name or promotional name used for the charitable and commercial interests of owner and donor, William Morris, 1st Viscount Nuffield. The name was assumed following Nuffield's gift made to form his Nuffield Foundation in 1943, it linked his business interests to his existing very generous philanthropy. The same enterprises had previously been referred to as the Morris Organizations and at first described itself as The Nuffield Organization, A Cornerstone of Britain's Industrial Structure.
