Alan McArthur from the CSIRO began his experimental burning program in the late 1950s near Canberra and published his landmark paper in 1962, “Controlled burning in eucalypt forests”. Leaflet No. 80, as it was known, proved a turning point for forest and fire managers across Australia. It led to the McArthur Forest Fire Danger Meter (FFDM) which first appeared in operational use in 1967 as the Mk 4. The CSIRO had developed its semi-automatic aerial incendiary machine dropping small capsules, with the first trial from a fixed-wing Cessna 337 at Manjimup in December 1965. In April 1969, the Forests Commission borrowed the second prototype of the CSIRO machine to carry out fuel reduction burning at Orbost. The success prompted the purchase of their own machine in 1970, which now sits in the Altona Museum.

The successful dropping of supplies to remote fire crews involved a great deal of experimentation. The result was a large heavy-duty cardboard container being developed in 1964 by Athol Hodgson from the FCV Fire Research Branch which employed fold-out wings and was called the “helibox”. It was suitable for supplies weighing less than 9 kg and best dropped from about 300 feet and became a standard technique. It was adopted Australia wide, but the wider availability of helicopters made the helibox eventually redundant.Unique to Victoria but adopted across Australia.Large cardboard box with "wings" to cause it to rotate when dropped from the air.

Lightning is one of the major causes of bushfires, particularly in the remote mountains. This lightning detector system was developed by Dr. Peter Kourtz at Canada’s forest fire research institute. By 1977, some 300 were in use across the country. The small mushroom antenna could detect short-range (20-mile) changes in electrostatic field associated with lightning strikes. It needed to be placed out in the open on a hilltop and away from nearby trees. It simply counted the number of "strikes". The detector doesn't seem to have a direction finding capability or be able to distinguish between cloud-to-cloud or cloud-to-ground lightning. It's not sure how this particular unit found its way to Victoria. The Bureau of Meteorology's (BOM) current lightning detector network uses radio waves emitted by lightning to pinpoint the location of lightning strikes. The network is operated by a private company that sends data to the BOM in real time. Lightning detection systems use sensors like antennas, GPS receivers, and processing systems to detect radio waves, also known as sferics. The systems calculate the lightning's location and speed by measuring how long it takes for the radio signal to reach the different antenna stations. The BOM also has a Thunderstorm Tracker that uses weather radar data to identify areas of potential thunderstorm activity. The tracker updates every six minutes and shows the direction thunderstorms are moving, as well as their expected position in 10, 20, and 30 minutesLightning detector 1970sQ-Techforests commission victoria (fcv), weather, bushfire, bushfire aviation

The Forests Commission and its successors continuously encouraged bushfire research and innovation. In 1946 a large parcel of industrial land was purchased at North Altona as a fire cache and workshop. The Altona workshop became a hotbed of new technological innovation… an exhilarating place where lots of things were invented and tested. In fact, a lot of Australia’s pioneering equipment development was led by staff from Altona, often in collaboration with other State forestry and fire authorities. The CSIRO also contributed significantly. The US Forest Service, the US Bureau of Land Management and US State agencies such as the California Department of Forestry and Fire (CalFire) as well as the Canadian Forest Service faced similar challenges and proved strong and willing partners in sharing knowledge, ideas, equipment and expertise over many decades. This collection of badges is testament to the relationships that were forged across the globe with the Altona workshop.

Based on the earlier successful tests with the RAAF Dragonfly in 1948-49, together with the effective use of aircraft during the extensive Gippsland bushfires in March 1965, the Forests Commission took the plunge and contracted its own dedicated Bell 47G in the summer of 1965-66. This was an Australian first for any forest or bushfire agency. Rappelling trials at Snowy Plains and Tallangatta soon followed, which led to operations based at Heyfield with a two-man crew to quickly attack small fires in remote locations. The Heyfield rappel crew was another Australian first and remained in place for the following two fire seasons but lapsed after concerns from the Civil Aviation Safety Authority (CASA) about the stability of the small and underpowered Bell 47G. Later in 1982, after nearly 18 years absence, the Commission recommenced rappelling operations using larger and more powerful National Safety Council (NSCA) Bell 212 and Bell 412 helicopters based in Sale, Gippsland. During the 1983 bushfires, a specially trained and equipped FCV crew rappelled by rope from a hovering NSCA helicopter to suppress a small fire in remote terrain in the Orbost Forest District.

Conrad Wood (Woody) graduated from the Victorian School of Forestry in 1957, and after postings with the Forests Commission Victoria (FCV) at Swifts Creek and Sirex surveys, he gravitated into the Forest Protection Division in Head Office in the early 1960s. He championed the setting up of proper contractual arrangements for aviation and was involved in implementing the first ongoing, organised contracts for firebombing in eastern Victoria in the 1960s. An early recipient of a prestigious Churchill Fellowship, Woody travelled extensively throughout 1969 in North America and Europe studying aviation in forestry and firefighting. Afterwards he was very active amongst the Churchill alumni. Woody had a passion for innovation and new technology and was instrumental in introducing new aircraft types and new approaches for forest firefighting and forest management. Amongst many other things, he played a major role in organising the trial of a RAAF C130 equipped with MAFFS for firebombing in south-eastern Australia in 1982-84, even piloting the lead plane. His inimitable style was crucial in successfully bringing together the cultures of the myriad organisations involved. Con advocated for the introduction of helicopters. He developed aerial fertilising and seeding techniques for forest management. He even managed to get involved in cloud seeding experiments for forest fire suppression and for improving water yield. Along with aviation, Conrad was passionate about literature, football, politics, food, drink, motorbikes, gardening and Glen Iris, to name a few. He was a committed campaigner on social justice issues and for many years read for vision-impaired people on public radio. He died in 2014. This painting of Woody by notable Australian artist Joyce McGrath OAM (also a Churchill Fellow) was done in the 1980s. Joyce asked Conrad to sit for this portrait which she planned to enter the Doug Moran National Portrait Prize. The portrait hung in Churchill House in Canberra, but when a new building was erected, it was returned to the artist/owner. The painting is now owned by Clare Harwood and is on permanent loan to the Forests Commission Retired Personnel Association (FCRPA) and is displayed at DEECA's Altona Museum.Painting of Conrad Wood by Australian artist Joyce McGrath OAMbushfire, bushfire aviation

The Canadians developed a machine that used "ping pong balls" instead of cylindrical incendiary capsules and, in 1977, the FCV purchased a Premo machine for evaluation. The 32mm-diameter balls were made from high impact polystyrene and contained 3.5g of potassium permanganate. They were injected with 1ml of glycol which would ignite after a short delay The first Premo machine used four slipper blocks, which were loaded via a hand-operated hopper which, when rotated forward, the balls would be fed into four feed chutes to individual slipper blocks. Each slipper block has an opening allowing individual balls to enter and exit once injected. The original design of the machine was not suitable to meet the burning objectives and a number of modification were necessary. Following close inspection and field testing it was clear that utilising four slipper blocks was excessive and would generate too much fire. It was acknowledged that satisfactory spacing could be achieved by using just one slipper block. Selective spacing could be achieved by the speeding up or slowing down of the slipper block transferring the capsules during the injection process. Regulating the speed that the injected capsules were being dropped controlled the amount of fire created on the ground. This machine was the result of many years of experimentation at AltonaSignificant development of aerial incendiary machines enabled expansion of the fuel reduction burning program across Victoria.Aerial Incendiary machine for use in helicopters Modification at the Altona workshops over many years by Barry Marsden forests commission victoria (fcv), planned burning, bushfire, bushfire aviation

The Aerial Drip Torch (ADT) was an idea conceived in Canada in the 1970s by John Muraro It was developed in 1982 by the New Zealand Forest Service to become the Ashley Aphid Helitorch. Forestry Tasmania acquired one of the machines and modified it in February 1987. Also known as a dragon helitorch it consisted of a large 135-litre tank containing jellied petrol, a displacement pump, propane ignition system, burner nozzle and fire extinguisher system. It was first trialled in Victoria at Swifts Creek in 1991 and the Aerial Drip Torch (ADT) has now become standard practice.Two Aerial Drip Torches (ADTs) were built in the 1990s by the Fire Equipment Development Centre at North Altona, They were developed in conjunction with the Department of Conservation and Land Management in Western Australia. The first was trialled during the 1991/92 autumn burning season. The machine proved to be successful and a second machine was introduced in 1998 to assist with burning operations across the State. The ADTs were commonly used for regeneration burning (controlled burning of logging slash). The first ADT introduced in 1992 had a dry weight of 160kg and a capacity of 130 litres, providing about an hour of operation. Following initial use, systematic modifications were adapted including improved ignition of gel at the drop tube, installation of an air bleed valve at the pump to assist pump priming and improved mounting brackets for the CO2 bottles and propane canister attached to the machine. The second, and lightweight ADT, introduced in 1998 had a dry weight of 68kg and a capacity of 200 litres due to a smaller lightweight frame and plastic (Polyfin) tank. In operation the ADT is suspended below a helicopter via four strops attached to the vessel and a cable to the helicopter cargo hook. Gelled fuel is dispensed via a drop tube which is attached to the pump outlet of the machine, and ignited via a gas torch. Safety features built into the first ADT were: a brass melting plug designed to be activated at 200 C bursting disc designed to burst at170 Kpa should the vessel over pressurise. a pressure relief valve set to 35 Kpa ( vessel operated between 16 &34 Kpa) a low pressure sensor designed to shut down the machine should the vessel pressure drop below 15Kpa. the vessel is filled with CO2 above the gelled fuel to eliminate ignition with in the vessel. CO2 is used to expel any residue of ignited gel from the drop tube to prevent ignition when flying outside the boundaries of the burning area.
