In 1988, as part of a Defence of Mainland Australian policy, defence of facilities of strategic importance in northern Australia were allocated to Army Reserve units. ‘A’ Squadron was allocated the defence of Tindal Air Force base located 15 KM outside Katherine in Northern Territory. Consequently the Squadron deployed on Exercise ‘Northern Explorer’ to gain first-hand knowledge of operating conditions for mounted and dismounted patrolling in the area.Two colour photographs of sink holes/rock depressions cbserved while on patrol during Exercise " Northern Explorer.

This rare vintage clothes iron is not just a functional item but a testament to the craftsmanship and ingenuity of an earlier era of the 19th century. Crafted from cast iron and featuring a wooden handle, it is a unique piece that adds a touch of authenticity and history to our collection. The inclusion of a funnel and chimney showcases the attention to detail in the design. A rare cast iron charcoal clothes iron with a wooden handle, complete with a funnel and chimney. The goose neck iron has a hollow base into which charcoal is placed. The small hole at the back has a sliding cover that was used to regulate the draft and temperature of the iron. To keep the charcoal glowing, the cover could be opened to allow more air or oxygen in to encourage the charcoal to burn. The iron could be swung back-and-forward to revive the charcoal. The fumes produced by the charcoal are carried away from the clothes by the large funnel that acts like a chimney at the front of the iron. The holes that line the base allow air to circulate and keep the charcoal ambers burning. This vintage clothes iron is not just a functional item but a testament to the craftsmanship and ingenuity of an earlier era. 'S' is stamped in a circle on the back of the iron.flatirons, laundry irons, cast iron laundry irons

Bushfire behaviour is influenced by many factors including temperature, relative humidity (RH), forest type, fuel quantity and fuel dryness, topography and even slope. But wind has a dominant effect on the Rate of Spread (ROS), as well as fire size, shape and direction. Wind speed can be measured using a variety of anemometers. This simple hand-held Venitimer was made by Elvometer in Sweeden, probably in the 1960s, and was designed for principally for mariners. Some models have a compass in the handle to measure wind direction. The small inlet hole on the side is faced towards the wind and air pressure lifts small plastic disk inside. The upper tube is tapered so that as wind speed increases more air escapes and stronger winds are needed to raise the disk. Wind speed in MPH is read from the side of the clear plastic tube. The waterproof container has instructions on use and conversion scales. Simple and robust device.Hand- held wind anemometer Instructions on use on containerbushfire, forests commission victoria (fcv)

This instrument measures elevation by sensing minute changes in barometric air pressure relative to a fixed datum point at sea level or a known elevation, such as the starting point of a major town during a road survey, and has an accuracy of +/- 20 feet when used in experienced hands. The finely divided scale around the perimeter of the face is marked from 0 to 6000 feet elevation and 25 to 31 inches of mercury (Hg) for barometric pressure The single fine counter-balanced hand or pointer rotates anti-clockwise with increasing elevation and decreasing pressure. The label "compensated" indicates that the instrument is constructed to compensate for the effect of temperature changes on the accuracy of readings.
