Bob (Herman) Hymans (a former member of the Royal Netherlands Navy) was born in Bloemendaal, Holland on 30th September 1922. During World War II he fought against the Japanese in the Dutch East Indies (now Indonesia) and was imprisoned in Changi and on the Burma Railway. After gaining qualifications as a Ski Instructor, Bob arrived in Falls Creek in July 1950. Working as an Instructor and Supervisor at Bogong Lodge, Bob decided his future was in accommodation. He was successful in negotiating an indenture for land from the State Electricity Commission (SEC). It took Bob two years to build his Grand Coeur Chalet but, tragically, it was burned down in August 1961. Bob also built the first Chairlift in Australia. This was a single chairlift and the structure was built from wooden electricity poles. He was constantly full of new ideas and proposals for the village. Bob Hymans died on 7th July 2007. This Collection of documents and letters tells the story of Bob's endeavours to develop Falls Creek into the ski village it is today.This item is significant because it documents the wide range of actions and responsibilities undertaken by the Falls Creek Tourist Area Management Committee.A circular to Licensees and Lessees expressing the Committee's thanks for co-operation given during the recent water difficulties.

Denis Gibbons (1937 – 2011) Trained with the Australian Army, before travelling to Vietnam in January 1966, Denis stayed with the 1st Australian Task Force in Nui Dat working as a photographer. For almost five years Gibbons toured with nine Australian infantry battalions, posting compelling war images from within many combat zones before being flown out in late November 1970 after sustaining injuries. The images held within the National Vietnam Veterans Museum make up the Gibbons Collection.

This photograph was taken at Wooragee Landcare workshop (Quoll), field day in Mt Pilot park on Bush Recovery: After the Fires. This is part of the Biodiversity Month on September 2004. The Bush Recovery workshop was held on Sunday 12th September 2-4pm with Christine Watson, Sue Berwick and Natasha Schedvin, and another workshop on Wednesday, 15th September, 9am to 12 noon with local biologist Glen Johnson and botanists Gill Earl and Christine Watson. The topics involved in the training involved what species have returned, what species haven't, what recovery studies are being carried out, how are the barking owls and phascogales faring, and why is Mt Pilot important. The photograph shows L-R: Colin Payne; Jerry Alexander; Geoff Galbraith. Bush fires are common in Australia due to several reasons. One is due to the geographic spread of fire's seasons, secondly, the absence of El Nino conditions are also linked to fires. Climate change also affected Australia's hot and dry seasons. Australia's climate began warming since the 1970s. Human-induced fires also contributed to this increase in temperatures across the nation. Bush fires happened in Mt Pilot in 2003 but it has recovered well since. This makes Mt Pilot an important site to understand bushfire recovery. This photograph contributes to the scientific and historical records on bushfire recovery in Victoria. It creates a picture of Victorian community activities and efforts on biodiversity, climate change, and environmental care.Landscape coloured photograph printed on gloss paperReverse: WAN NA 0A2A0N0 NN2 0 163 / (No. 2)wooragee, wooragee landcare group, wooragee landcare, bush fires, bush recover, mt pilot, biodiversity month, botany, botanists, bush recovery, quoll, foxy, fox, forest, environment, climate change, bushfire recovery, bushfires, 2004 bushfire, field work, after the fires, fire, biodiversity

The work of the Australian Survey Corps is to make maps for the Army. At the outbreak of war very little of the mainland had been mapped, especially the northern parts. The best maps in existence of the N.T. coast in Dec "41 were those made by Matt Flinders in 1801 -1802. The Army soon got out new maps of all important areas including much of the inland. Later it was decided to bring the complete coastline up to date. Several parties put in between them six months on the coast during the dry season of "45 but a couple more months would be needed to complete the program when the "wet" interrupted the work. A small section from Buckingham Bay - Groote Eylandt was still untouched and this diary covers that section of the N.T. Coast. A survey party of four men was chosen who were to be transported from place to place by the AK121 Aroetta - a ketch of 25 tons belonging to an army unit called N.T. Coastal Recce whose work it was to patrol the coast and as well do air - sea rescue. The survey party: Lieut Jack Worsley (the Loot) Sgt Jack Love, Spr Jack Cook, Spr Pat Hede. Crew of Aroetta: Liet Ralph Warne (Skipper), Sgt Buckley (Buck) (First Mate and Orderly Rm), Sgt Jim Terjesen (Jumbo) Bosun, WO2 Tom Davis (Engineer), Cpl Kevin Monk (Artificer), L/Cpl Jack Cox (Deck Hand), Spr Jack Andrews (Signals), Spr Laurie Rament (Ass.

This flip top pocket steel ash tray was at the beginning of the social "cleaning up" of cigarette ash and related products. This cigarette waste container was for those occasions when it was polite not to throw the cigarette ash and used up cigarettes "buts" on the ground, or if working in any rural area during a dry fire prone season, when discarding burning cigarette waste could set up a severe "bush" fire. It was also at the beginning of an intensive look at the affects of smoking upon the health of users. Later in the 1900s was a time when medical evidence supported a ground swell of the anti smoking movement which resulted in further restrictions of the use cigarette smoking in public places. Before the anti cigarette smoking revolution, it was both fashionable and manly to either roll your own cigarette or open up a packet of "tailor made's". In the rural and man's man environment the roll your own provided a visual acknowledgement that the user was "true blue" Aussie male and not a city boy. The cycle of use of cigarettes has drastically changed from when this item was first used. Today's society (post 2000) has produced a ground swell of government and non government organisations whose aim is provide a cigarette "ash" free environment and society. This is highlighted in the beginning of the 2000 millennium by a cigarette "Free" Australia campaign, and the pocket flip top personal ash tray as a practical solution for butt litter disposal.This pocket ash tray not only was used when social graces required it to, but also provided a container for any unfinished cigarettes or stogies (cheap half used cigars). In rural areas (open fresh air countryside), where time was always made available for the "smoko" (Australian rest period), at any time, especially after some hard physical work, the ability to have a self contained ashing apparatus, not to offend the gentler folk, was a pre-requisite . The rural environment, in the days of these cigarette ash containers,was one which could range from harsh and unforgiving to mild and relaxing. Smoking could be enjoyed anywhere and at any time without too much "fussing" around. This ash tray was mobile, convenient, unobtrusive and regarded by the user as being considerate to those around. It also eliminated the tell tale evidence that the "no smoking" signs had been ignored.

The Olive-Backed Oriole are very common birds for northern and eastern Australia, as well as New Guinea. Similar to the Yellow Oriole, this species is more versatile yet less distinctive in colouring. The streaked underparts and red bill and eyes are easy identification features of this bird. Both sexes look very similar, with female colouring being slightly duller than males. This species frequents open forests and woodlands, and can tolerate dry climates. Most of this species breeds from September to January during the tropical wet season in northern Australia, but some are known to migrate south to breed in the summer. This species eats mainly native fruit, berries, and insects. This specimen is a good example of this species, but the colouring is very dull compared to living birds. This specimen has one red eye, which is a good example of a distinctive feature of this species. This specimen is part of a collection of almost 200 animal specimens that were originally acquired as skins from various institutions across Australia, including the Australian Museum in Sydney and the National Museum of Victoria (known as Museums Victoria since 1983), as well as individuals such as amateur anthropologist Reynell Eveleigh Johns between 1860-1880. These skins were then mounted by members of the Burke Museum Committee and put-on display in the formal space of the Museum’s original exhibition hall where they continue to be on display. This display of taxidermy mounts initially served to instruct visitors to the Burke Museum of the natural world around them, today it serves as an insight into the collecting habits of the 19th century.This specimen is part of a significant and rare taxidermy mount collection in the Burke Museum. This collection is scientifically and culturally important for reminding us of how science continues to shape our understanding of the modern world. They demonstrate a capacity to hold evidence of how Australia’s fauna history existed in the past and are potentially important for future environmental research. This collection continues to be on display in the Museum and has become a key part to interpreting the collecting habits of the 19th century.This Olive-Backed Oriole has a faint olive-green head and back, and a faint red-tinged beak. Its body is cream coloured with brown streaks. It has one red eye. This specimen appears to be immature and/or female, as it has a pale pill and a duller-olive green back, with streaks quite high up on it's chin, which is indicative of an immature female of this species.

The red-winged blackbird is native to North America. They live in a verity of places from southern Alaska at its northern most point, to the Yucatan peninsula in the south and covers the greater part of the continent reaching from the Pacific coast of California and Canada to the eastern seaboard. Populations that are most northerly migrate south after the mating season, but some of the populations in the central and western United States, Central America and the Gulf Coast are resident year-round. In the breeding season, Red-winged blackbirds are found in a range of fresh and saltwater environments, including in small trees and bushes along marshes and watercourses, in agricultural areas and dry meadows. During migration, they can be found in, pastures, prairies and cultivated fields. They are polygamous. In the north, the early arrival and tumbling song of these birds are welcome indications of spring's return. The Red-winged blackbirds are known for their scarlet and yellow shoulder patches on this specimen are rather dull and the feathers are not as glossy black as they are in other images.

This iron chaff cutter was a vital piece of rural machinery especial for cattle in areas subjected to limited grass growing seasons. The Kiewa Valley and Alpine regions were up to the 21st century "snowed" in. The conditions requiring summer crops and fodder to be prolonged for the harsh winter climate are now becoming less and less and may confirm the precursor of "global warming". The Kiewa Valley is still a strong base for dairy cattle and other stock requiring all year access to hay/grass supplies. The use of, now defunct, Tobacco drying sheds for the storage of hay and other fodder is typical of the Australian farmer/grazier's adaptability to utilise anything available.

Minnie PWERLE (c1910-2006) Atnwengerrp/Utopia Minnie Pwerle's Dreamings consist of elements of 'Bush Melon' and 'Awelye'. Awelys-Atnwengerrp' is depicted by a series of lines painted in varying widths and colours. These patters represent the lines painted on the top had of women's bodies during ceremonies in Minnie's country of Atnwengerrp. 'Bush Melon' is depicted using linear design of curves and circles in different colours creating a very loose and bold design. This dreaming tells the story of this lovely sweet food that comes from a very small bush and is only found in Atnwengerrp. Once very abundant and fruiting in the summer season, the Bush Melon is now hard to find. Minnie and other women used to collect this fruit (that was green in colour and then ripened to a brown colour) and scrape out the small black seeds. They would then eat the fruit straight away or cut it in pieces and skewer them onto a piece of wood to dry then to be eaten in the coming months when bush tucker was scarce. These artistic symbols carry potent spiritual meanings.. The physical creation of these Dreamings in an important part of the continuation of an ancient and rich cultural heritage.

Many of the brigade and group base radios were situated in private residences and operated primarily by fire fighters wives who held the position of Communications Officer, either registered as a brigade member or informally. Edna Barrie was never registered as an operational brigade member but operated informally as an assistant to her husband Bon. She was however a member of the Melton Fire Brigade Ladies Auxiliary from its inception in 1968, a non-operational position. Edna kept up to date with radio procedure following the 1967 handbook; preparing maps, plotting compass points and taking notes on weather forecasts from the SA Border and Western District. Daily notes were taken in anticipation of fire warnings. These log books and daily radio traffic were incidental to the regular radio schedules.

M&MTB Season Greetings Card 1926 – 1927. The card consists of a heavily embossed brown cover with the MMTB logo on the front cover, with a printed sheet internally and tied together with a green ribbon. The photographs have been overlaid with a gold borders and the message has been printed in gold ink. An experienced printer estimated it would have taken some two hours to hand set the message, the press operator another two hours to get the registration correct before printing it and after printing allowed up to four days for the gold ink to dry before handling the paper again. This is certainly a work of art in terms of printing. Whether it was done by the M&MTB’s internal printing office is unknown. Of the view it would have only been sent to “select” people.

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.

Bushfire behaviour is influenced by many things including temperature, relative humidity, forest type, fuel quantity and fuel dryness, topography and even slope. Wind has a dominant effect on the Rate of Spread (ROS), and also bushfire size, shape and direction. Fuel arrangement is as important as fuel quantity (tonnes/ha). Fibrous and ribbon bark, together with elevated and near-surface scrub fuels act as ladders which lead flames into the tree canopy. But the availability of fuel to burn depends largely on its moisture content. When it exceeds 20-25% not much will burn, whereas 12-15% is generally ideal for fuel reduction burning, but if the moisture content drops as low as 7-10% virtually everything will ignite, and fire behaviour becomes extreme. During the afternoon of the Ash Wednesday bushfires on 16 February 1983 fuel moisture contents were recorded at Stawell as low as 2.7%. Fine fuels like leaves and bark can rapidly absorb moisture after a shower of rain, or from the air when the Relative Humidity (RH) is high, and the temperature is low. Conversely, they can also dry out very quickly. So even though the overall fuel quantity in the forest doesn’t change, the fine fuel availability can increase rapidly from zero after rain to many tonnes per hectare as the fuel dries out. This can happen over a few hours on hot and windy days. Heavy fuels like logs on the ground take longer to dry out. Since the 1930s foresters, firefighters and researchers have been working to develop quick and reliable techniques for measuring fuel moisture content. One of the most accurate methods is slowly drying a sample of fuel in a conventional oven for 24-48 hours to remove all the moisture and measuring the weight difference, but this takes time and is not practical in the field when rapid measurements are needed. But oven drying is often used as a benchmark to compare other methods. Microwave ovens are faster but can cause uneven drying and even char the fuel. They are also not very practical for use in the field. Some mathematical models rely on weather records such as rainfall, wind speed, evaporation, cloud cover, shading, relative humidity, slope, aspect and season of the year to predict soil and fuel moisture. The Keetch-Byram Drought Index of soil dryness is the most common. But complex fuels with leaves, twigs, grass etc make the predictive models often inadequate for fine fuels. The most common technique in Victorian forests until recently was the trusty Speedy Moisture Meter. Originally developed in England during the 1920s for measuring moisture in wheat and other grains it was adapted for Australian forest fuels in the 1950s (I think). Fuel was first ground using a Spong mincer, often attached to the bullbar of a vehicle, and a small sample placed into the Speedy together with a measure of calcium carbide and then sealed. A chemical reaction created gas pressure which was read on the external dial. There were important techniques with cleaning, mincing and using the chemicals with the Speedy to give reliable readings, but it was quick, inexpensive, robust, portable and practical in the field. It was used routinely before igniting a fuel reduction burn or measuring fuel moisture differentials on slash burns. But in about 1996, Karen Chatto and Kevin Tolhurst from the Department’s Creswick Research Station developed the Wiltronics Fuel Moisture meter which measured electrical resistance. Wiltronics is an Australian owned company operating from Ballarat. The final result was a kit that was portable, accurate and could reliably measure fuel moisture contents between 3% and 200%. Although expensive, it is now widely used by fire agencies around the world which has virtually relegated the Speedy to the back cupboard.Prototype Fuel moisture meterT-H Fine Fuel Meterforests commission victoria (fcv), bushfire, forest measurement
