This three-dimensional Distant Signal is part of a Flagstaff Signal set of ball, cone and drum shapes. It has been woven and then fabricated with strong metal swivel fittings and loops for suspending from a high point on a flagstaff at a signal station or on a ship’s masthead. The cane signal was constructed to withstand all weather and to be visible from a long distance. The gaps between the woven cane allow air to pass through, minimising possible swaying. Similar sets were made from rope or fabric. Warrnambool's Flagstaff was erected in 1854. Its primary use was to display visual signals that could convey messages between land and sea. It was also used to notify the local population of the approach of ships. One of the popular signalling codes in use in the early-to-mid 1800s was the Marryat’s Code but there were others in use as well; there was no one standard code. In 1857 the International Marine Conference adopted an International Code of Signals as a standard communications system for all vessels that could be understood in many different languages. The Normanby Advertiser reported on June 5th 1857 a query from the Post Master General as to whether the request of the Chief Harbour Master would be carried out, in that Warrnambool would receive a new flagstaff and a set of Marryatt’s signal flags. The Table of Codes was published, showing how to use combinations of these flags to send messages. The Code was revised in 1887 to cover situations where distance, light, wind and weather conditions affected the visibility of the flags and prevented clear communication. The first report of the International Code of Signals Committee of 1897 warned signalmen not to rely on ordinary semaphore flags and introduced a Distant Signal Code using either particular semaphore flags or the three-dimensional shapes of a ball, cone and drum that aligned with the semaphore flag shapes of a circle, pennant and square. International Code of Signals In 1931, after World War I’s experiences in using signal codes, the International Code of Signals conference in Washington revised and published the rules for the conduct of signalling. One of the changes was that “the use of the Distant Signals and of fixed semaphore was abandoned”. It is of interest to know that modern marine law in many countries insists that a set of Day Shapes must be carried onboard vessels of a certain size. These highly visible geometric shapes are used at sea in daylight to communicate messages between vessels. They are used in a similar way to the Distant Signals, in that different combinations of shapes represent different messages. The set of shapes includes a ball, cylinder, cone and diamond. The shapes are hung between the top of the vessel’s foremast and the front of the vessel. They are only coloured black and are about 1.5 metres high. The vertical line of shapes can mean messages such as Boat not under command, Fishing, and Under sail and power.Distant Signals were an important means of marine communication from the late 1880s to the early 1930s, including during World War I. They were an advancement to the International Shipping Codes and safety. The cane signals’ shapes appear to be the same from whatever direction they are viewed, removing confusion about the message they convey. The same shapes continue to be used today for the sets of Day Shapes used as marine navigational signals that are mandatory on certain-sized vessels.Distant Signal Cone, part of a Flagstaff signal set.

The AWAS was formed in 1941, and its main objective was to support the Australian army in various ways. Over 24,000 women served in the AWAS, performing critical support roles such as clerical work, vehicle maintenance, and communications.

The Heliograph MkV is a fascinating piece of historical surveying and communications equipment. It was primarily used for visual signaling by reflecting sunlight with a mirror to send coded messages over long distances. This method was primarily useful in remote areas where other forms of communication were not available. The MkV model, specifically, was widely used by the British Army and other military forces from around 1906 until the mid 1960s. It remained in use with the Australian Army Survey Corps until the mid 1980s. The device typically included a 5 - inch mirror and was often mounted on a tripod for stability. Initially the instrument was used to communicate between survey stations using Morse code to coordinate their activities. Later when better forms of communication were available, they were used for precise angle alignment where the sunlight reflection from the mirror was targeted between the survey stations to give very accurate results. The MkV was relatively light weight and portable, making it ideal for use in the field. It could be setup and adjusted quickly. The heliograph had an adjustable mirror that could be tilted to reflect sunlight towards a distant receiver. Surveyors could align the mirror using a sighting device. Whilst it was primarily used by the Military it was also used in civil surveying particularly in the remote areas of Australia. The British Army Mark V version uses a flat round mirror with a small unsilvered spot in the centre. The sender aligned the heliograph to the target by looking at the reflected target in the mirror and moving their head until the target was hidden by the unsilvered spot. Keeping their head still, they then adjusted the aiming rod so its cross wires bisected the target, they then turned up the sighting vane, which covered the cross wires with a diagram of a cross, and aligned the mirror with the tangent and elevation screws, so the small shadow that was a reflection of the unsilvered spot hole was on the cross target. This indicated that the sunbeam was pointing at the target. If the sun was in front of the sender, its rays were reflected directly from this mirror to the receiving station. If the sun was behind the sender, the sighting rod was replaced by a second mirror, to capture the sunlight and direct it onto the main mirror to reflect it to the receiving station.. 1 Brish Army "Mance" Mk V A253 Heliograph has two 125mm diameter mirrors on a brass arm with targeting attachments.

This building is still intact at the Nhill Aerodrome. Some of the infrastructure is also in place or can be evidenced by its foundations.The Aeradio building was built on the present aerodrome in 1937. This was one of only sixteen buildings of this type built across Australia and it housed radio communications and guidance equipment. The building and its equipment were part of a comprehensive system of radio towers, signalling and meteorology equipment aimed at providing safer navigation for aircraft travelling throughout Australia. The facility closed in the 1960sThis photo is significant due to it having been taken soon after the building was constructed. It is the earliest known photograph taken on an open to the public day before the receiver aerials were erected.The Aeradio building was built on the present (2012) aerodrome in 1937 or 1938.
