Under this arrangement, the club organised and maintained flight training operations and in return received three de Havilland DH.60 Cirrus Moths with the first aircraft arriving in July that same year at Mascot Aerodrome.

This site was named Hargrave Park Aerodrome and officially opened in September 1930 with over 20,000 attendees including the Governor of New South Wales, Sir Phillip Game.

It played a vital role in providing skilled instructors, aircraft, and maintenance facilities to train aspiring cadets for the Royal Australian Air Force.

Following the war and as the Jet Age emerged and Mascot evolved into Sydney's International Airport, the Department of Civil Aviation instructed the club to move to Bankstown Aerodrome.

In 1949, the club relocated to the former Royal Australian Air Force hospital premises, with the official opening conducted by the Patron and Governor of New South Wales, Sir John Northcott.
