Construction started on the aerodrome in 1942 and was still under construction in 1944 as part of a proposal to base a United States Navy Fleet Air Wing in Sydney should the need arise. Initially planned with three runways, No.1 (5000 ft) and No. 3 (6000 ft) runways were serviceable, however construction of No. 2 runway (5000 ft) was abandoned. A total of eight aircraft dispersal hideouts were constructed and accommodation was a farm house and a former Civil Constructional Corps camp.
In 1969, Fleurs was considered as a site of the second airport for Sydney. The aerodrome is now utilised as precision ground-reflection antenna range operated by the University of Sydney, known as the Fleurs Radio Observatory.
