CAC also undertook production of the Pratt & Whitney R-1340 engine used in the Wirraway and also built some propellers when supplies from alternative sources became problematic.

While CAC largely produced Australian versions of foreign aircraft, it also developed a number of original designs during and after World War II.

The Wackett was a simple trainer aircraft, but later designs during World War II were the sophisticated Woomera and CA-15, however these types were destined to fly only in prototype form.

In 1964 after a large amount of political lobbying CAC began producing components for the Sabre's replacement, a version of the Dassault Mirage III, as a subcontractor to the Government Aircraft Factories (GAF).

CAC produced an extremely wide range of aircraft for the Royal Australian Air Force and civilian operators.

The company was part of the Australian Aircraft Consortium which designed the A10 Wamira, but this programme was cancelled in 1985 shortly after the prototype was completed.

At the time of purchase by Hawker de Havilland, CAC had begun delivering components for the GAF-built version of the F/A-18 Hornet.

CAC major shareholder in the 1950s was General Motors Holden and from 1946 until 1973, Comair produced over 3,600 bus bodies, primarily on Bedford OB, SB and VAM 70 chassis for Victorian operators.
