This photograph shows Gladys Marriott, aged 15, in the potato fields of her father's property in Moorabbin. Her cousin Graeme (centre) and younger brother Alfred (right) are with her. Moorabbin is a suburb in the City of Kingston that was originally established as a rural market gardening communityThe Marriott property in Moorabbin was adjacent to a secret wartime wireless receiving station established in March 1942 in Chesterville Road, Moorabbin. The station was established on requisitioned market garden properties, and soon housed WRAN (Women's Royal Australian Navy) personnel and up to 35 US Navy servicemen. The Navy personnel intercepted Japanese coded communications and then despatched these by motorbike messenger to Queens Road, St Kilda where the Directorate of Naval Communications and the code-breaking unit called FRUMEL (Fleet Radio Unit - Melbourne) were housed. The information intercepted by the wireless receiving station helped shape the Allied response to Japan's advances in the Pacific. Declassified defence records show that this unprepossessing station handled some of World War II's most sensitive secrets, however the local community were unaware of its significance. Gladys Marriott, working on her father's property, would regularly take the family's cows to graze in the fields adjoining the station with no concept of what the Navy personnel were doing.

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

After the 1939 bushfires, the Forests Commission Victoria invested heavily in a radically new communications network. After suffering some inevitable delays due to the war, radio VL3AA switched into full operation in October 1945 proudly beaming out 200 watts across the State. But by today’s standards, the technology was primitive and the reception poor unless the user was on a high point somewhere. The radio signal was "line-of-sight" and bounced between fire towers and relay transmitters across the mountains back to the District offices. The advent of solid-state electronics in the 1960s replaced the more delicate valve sets which enabled greater use of vehicle mounted radios. The Commission continued to research, develop and build new radios at its many workshops around Victoria. The network was supported by a large team of skilled radio technicians. The more secure and versatile State Mobile Radio (SMR) digital trunk system came into operation in about 1995. Upgraded Tait Radios were purchased in 2014 after recommendations of the 2009 Bushfires Royal Commission. But it was the convergence of separate technologies such as 5G mobile phones, high-capacity and light-weight lithium batteries, Wi-Fi, the ever-expanding internet, cloud data storage, digital cameras, GPS, personal organisers and hundreds of supporting Apps into powerful smartphones and tablets which revolutionised bushfire communications from the mid-2000s.

This contraption is thought to have been developed in the FCV radio workshops at Surrey Hills. It's basically a STC vehicle radio which has been mounted on a backpack frame and powered by a heavy lead-acid battery. The backpack frame was manufactured at the Altona fire equipment development centre. A considerable number of these radio units were made and distributed to the field.bushfire, radios, forests commission victoria (fcv)

Red Cross Field Officer Carmel O'Shea was a disc jockey at the Australian Forces Radio station operated by the RAAF. They broadcast to all Australian forces in Phuoc Thuy Province. Miss O'Shea, who was attached to the 1st Australian Field Hospital, Vung Tau, gave this photograph to Lt Patricia Ferguson, Royal Australian Army Nursing Corps, who served at 1st Australian Field Hospital in Vietnam from 18 Feb 1970 until 05 Nov 1970.

The painting was donated to ANZCA in 1995 by Dr Bernard Dunn. Bruce Fletcher, from Melbourne Victoria, studied under William Dargie, who had been an official war artist during the second world war. Fletcher followed the same pathway as his mentor and was the first of two official war artists appointed during the Vietnam War. His artwork are held in the art collection of the Australin War Memorial, Canberra. The title of the painting, 'Dust Off' is a term adopted in Vietnam which refers to the medical evacuation of sick or wounded soldiers, from the field, by a helicopter. It was originally a radio call sign selected from a US Navy Signal Operations book in 1963. [ref. 'Medicine at War. 1950-1972'].In June 2012, a Royal Children's Hospital Anaesthetic Registrar attended a College Tour conducted by Dr Rod Westhorpe when he saw the painting and informed us that the term 'Dust off' emanates from the Korean War and is in fact the acronym for Decisive, Unwavering, Support to our Fighting Forces'. The painting was based on a black and white photograph taken in Vietnam in 1971. An image of the photograph is located in the electronic supplementary file. Oil painting on board of a scene in which a military helicopter is about to land with a group of soldiers in the foreground, one wounded and one soldier standing. A cargo military helicopter is in the distance flying away from the scene.
