Australian Six (Australia)

Australian Motors Ltd was an automotive manufacturer based in Ashfield, New South Wales, that operated from 1919 to 1926. The company initially imported vehicles under the name AMERICAN SIX, which were modified by F.H. Gordon & Co. with new badges. To enhance local production, Australian Motors established a large factory in Ashfield, where they began assembling vehicles with a higher local content, including a distinctive radiator designed in the form of a classic Grecian temple.

The vehicles produced by Australian Motors were mechanically based on American designs, featuring a 23 horsepower Rutenber engine with a displacement of 3,772 cc, coupled with a Grant-Lees 3-speed gearbox. The cars had a wheelbase of 122 inches (3,098 mm) and offered options for both artillery and disc wheels. Despite promising initial sales, the company faced significant challenges due to the poor quality of many engines, which did not meet contract standards. This necessitated extensive rebuilding before installation, leading to increased costs that eroded profit margins and ultimately contributed to the company's financial collapse in 1922.

Following the bankruptcy, the assets of Australian Motors were acquired by Harkness & Hillier of Fivedock. A revised model was introduced, featuring a 26 horsepower 3,816 cc Ansted overhead valve engine. This model was produced in limited numbers until 1926. It is estimated that around 1,000 units were manufactured, making it the most prolific Australian car model prior to World War II.
