1930 to 1961
FCV negotiated with the Air Board for the provision of aircraft for reconnaissance and detection of fires. First fire detection flights were by Air Force Westland Wapiti aircraft. These patrols became a regular fire season operation. Testimony
from the 1939 Stretton Royal Commission provides information about these early aerial fire patrols.
Aerial application of insecticide powder
to control damage by case moths in a conifer plantation. The report of this work concludes "Remarkably successful results were obtained, auguring well for the future control by this means of like destructive insect visitations ...this is the first occasion (this) procedure has been adopted in Australia"
First aerial photography operations for the FCV from which mosaics were prepared of 15,000 acres of forest.
Initial use of radio communication in Victorian forestry, born of the need to report fire sightings from aircraft patrols direct to the local forest staff.
First experiments in "bombing" fires using chemical dropped from aircraft in cartons. This work, on a technique widely accepted as an American development, not only coincided with early water bombing experiments in the USA, but pre-dates by some years, any known records of using fire retardant chemicals in preference to plain water.
First airborne command of firefighting operations via direct radio communication to ground crews.
Aerial photography of 13000 square miles of forest completed, including much inaccessible country. These surveys enabled the planning of roading systems for fire protection and the harvesting of large quantities of timber for the post war building boom.
Experiments conducted with aerial spraying to kill vegetation for the preparation of firebreaks.
Further trials in firebombing using Liberator, Lincoln and Mustang aircraft to drop chemicals in metal tanks designed to burst on impact.
First use of a helicopter for fire control work in Australia. The Sikorsky machine was the only helicopter in the country at the time, and was used for reconnaissance and mapping, and the deployment of men and equipment in rugged forest in the eastern ranges. This success led quickly to helicopter surveillance flights for timber assessment and forest type classification.
First recorded aerial drops of food supplies to an isolated firefighting crew. This technique has been considerably improved in recent years by the development of specially designed free fall containers which provide aerodynamic lift to cushion impact with the ground.
The FCV constructed the highest airfield in Australia, at 5,300 feet on Snowy Range, strategically located in the heavily forested eastern ranges, as a base for various aircraft operations.
1961 to 1991

First organised operational control of wildfire by firebombing in Australia. Two Piper Pawnee agricultural aircraft bombed a wildfire in rugged mountain forest with fifteen loads of fire retardant slurry
Infra red heat sensing techniques were introduced with an image converter. This instrument is used by an observer in an aircraft to map the edge of a fire when smoke obscures it from normal vision.
Aerial ignition techniques used for suppression of a wildfire. Specially developed incendiaries were dropped from a helicopter to burn out 5,000 acres between a safe control line and the advancing front of a large and damaging forest fire
The first aerial spraying of a fungicide was carried out over 1200 acres of pine plantations to control a pathogen causing serious needle cast. New operational techniques were developed for the marking of accurately spaced swaths to achieve uniform distribution of the spray
Fuel reduction burning by aerial distribution of incendiaries over large areas was commenced as a routine fire protection measure
Trials of Canadian Twin Otter fitted with membrane tank for firebombing. The membrane system relied on releasing the load by a knife rupturing a membrane in the base of the underbelly tank. System proved too complex to be operationally viable.
FCV purchases Premo aerial incendiary machine from Canada. Machine uses “ping pong ball” type incendiaries.
Commencement of trials of C130 Hercules, on loan from RAAF, fitted with MAFFS (Modular Airborne Fire Fighting System) for firebombing. Trials continued over two fire seasons. System ultimately proved non-viable due to high costs and long turn around times.
February 16th, Ash Wednesday. Over 40 aircraft instrumental in all aspects of fire control operations despite severe operating conditions
Major advancement in infra-red technology with introduction of airborne infra red line scanning-significantly improving ability to map large areas. Introduction of Department's own FLIR (Forward Looking Infra Red) equipment enhanced efficiency of firebombing, fire mapping and mopping up operations
Commencement of CSIRO project Aquarius to study relative efficiencies of DC-6, medium helicopters (Bell 205) and agricultural fixed wing aircraft for firebombing.
Largest single aerial firefighting operation in Australia at lightning-caused fires in North-Eastern Victoria. Extended over three weeks and at one stage involved 20 helicopters and 16 fixed-wing aircraft.
