The Hillman Car Club of South Australia Inc. was formed in 1988, and has as its main objective the preservation of Hillman vehicles and derivatives thereof. Additionally it aims to provide a source of information about those vehicles and provide assistance to people wishing to own and maintain Hillmans or who simply have an interest in them.

The Club has a membership of around 90 to 100 spread across Australia, but mainly located in South Australia. Male and female members are of all ages and from all walks of life. Their cars are varied ranging from a 1913 Hillman Roadster (the oldest Hillman in Australia and believed to be one of two remaining in the world), a 1932 roadster and 1935 sedan, through various models of Minx to 1967, Hillman Husky, rear engine Imps and Hunters of the late 1960s and early 1970s.

Commercial vehicles are represented by a Hillman utility and the heavier Commer trucks. Members also own other Rootes Group vehicles, some of which their models uniquely marketed in Australia e.g. Hillman Gazelle and Humber Vogue
