The HP-85A was Hewlett Packard's first Series 80 microcomputer, introduced about 1979. It had a keyboard, a dual alpha/graphics monochrome display, a bidrectional alphanumerics and graphics printer, and mass storage tape drive all integrated into a marvelously designed and compact case. It's operating system was seemlessly integrated with a powerful BASIC programming language that included intuitive graphics and input/output capabilities. The HP-85A was also wonderfully expandable through four ports on the back of the case for adding plug in ROMS and modules.

This representative example demonstrates a mariner’s astrolabe. Historical examples are rare. There are less than one hundred known to exist and most of these have been recovered from shipwrecks, many from Spanish and Portuguese vessels. An astrolabe is a measuring device once used to navigate the seas by observing the sun and stars to measure their altitude. The measurement of altitude could then be used to calculate the ship’s latitude but at that time in history there was no means of measuring longitude. The body of the navigational astrolabe was cast brass and much heavier, and less complicated than the variety used on land. The heavier weight and cut-away shape reduced the effect of the wind and waves when trying to use it at sea. A mariner’s astrolabe or ‘star finder’ is a simplified version than that used by Arabic astronomers to find the altitude of the sun and stars above the horizon, and time of the sunrise and sunset. It is a forerunner to the quadrant, octant and sextant and was popular for about 200 years over the 1500s and 1600s to find the latitude of a ship at sea. The user held the astrolabe at eye level and, usually with assistance, aligned the stars through the two small sights (pinnules), then read the altitude indicated by the pointer on the arm. It could also be used to sight the sun by holding it lower down, aiming it at the sun, and adjusting it until the sun shone through both pinnules. This astrolabe is an example used to demonstrate the mariner’s astrolabe, which was navigational tool of the 1500s and 1600s, in the time before longitude was able to be determined. It is a forerunner to modern navigation technology. Mariner’s astrolabe – a representative example. A gold painted, disc shaped object with cut outs and revolving arm in centre.

This Engine Room section of a ship's telegraph system was part of the equipment of the Ports and Harbour ship the SS Rip. The vessel serviced and maintained the lights and buoys at Port Phillip Bay and Queenscliffe. The SS Rip was possibly the former gunboat "Albert". The ship’s communication system that was used from the late 19th century to early-to-mid-20th-century is called an Engine Order Telegraph (E.O.T.) or ship’s telegraph. The system has two parts, the Bridge Section and the Engine Room Section. The Bridge Section is usually mounted on top of a pedestal, and the Engine Room Section is often attached to a vertical surface. The standard commands printed or stamped onto the dial are the directions of AHEAD and ASTERN, and the speeds of STOP, FULL, EASY, STD. BY. and FIN. ENG. The ship’s pilot on the Bridge of a vessel sends his Orders for speed and direction to the to the Engine Room with the E.O.T. He moves the lever or levers, depending on the number of engines the ship has, to change the indicator on the Bridge Section’s dial to point in the new direction and speed of travel. This change causes the Orders to be duplicated on the Engine Room Section’s dial and a bell to signal the change simultaneously. The engineer then adjusts the ship’s engines and steering equipment to follow the pilot’s Order. The manufacturer, Mulne Bros., was a copper and brass works at 166 Sussex Street Sydney, in December 1892, and previously from 1870 at 128 to 130 Sussex Street. The company made and sold a wide range of equipment including machinery and gauges for the Railways.The Engine Room section is significant for being part of the communications system on the ship SS Rip, owned by Melbourne's Ports & Harbours department and used to service and maintain the navigation signals of Port Phillip Bay and at Queenscliffe in the mid-20th century. The dial is an example of marine equipment made in Australia and used for the safety of Victorian vessels. It is also significant for being made by an early Australian manufacturer, Milne Brothers of Sydney.Engine Room Section of a ship’s telegraph or Engine Order Telegraph (E.O.T.).

This collection of 19 photos was most likely taken in 1979 in Air Survey Squadron. The PDP 11/70 minicomputer shown photos .2P to .3P was the operating system introduced in 1977 as the mainframe system for the control of the APC4, aerial triangulation block adjustments, SORA OP Analytical Orthophoto control, APR Analytical Terrain Profile Recorder computation, graphics, and general computing. The Zeiss (Jena) Stecometer analytic stereocomparator for air photography shown in photos .5P to .9P was introduced at Air Survey Squadron in 1963. Aerotriangulation production was expedited using computers for analytical photogrammetric processes. The technician accurately measured between pass, tie, and survey control points on aerial photographs. The OMI/Nistri AP/C-3 analytical plotter shown in photos .10P and .11P was introduced in 1972–1973. Photo .11P shows a coordinatorgraph attached to the AP/C-3. The Zeiss D2 Planimat Stereoplotter shown in photo .12P was used for analytical orthophoto control. Wild PUG4 point transfer devices shown in photos .17P to .19P were introduced in c1968 superseding the PUG2 devices. PUG4 devices were used by technicians to stereoscopically view the photography containing the survey control points and the mapping aerial photography. The Control points were transferred from the control photography to the mapping diapositives of aerial photography by drilling their locations into the photographic emulsion.This is a set of 19 photographs of Air Survey Squadron personnel operating aerotriangulation equipment at the Army Survey Regiment at Fortuna, Bendigo, c1979.

A sailing block is single or multiple pulleys with one or more sheaves that are enclosed in an assembly between cheeks or chocks. In use, a block is fixed to the end of a line, to a spar, or a surface. A rope line is reeved through the sheaves, and maybe through one or more matching blocks at the far end, to make up what's known as a tackle. The purchase of a tackle refers to its mechanical advantage. In general, the more sheaves in the blocks that make up a tackle, the higher its mechanical advantage. The matter is slightly complicated by the fact that every tackle has a working end where the final run of rope leaves the last sheave. More mechanical advantage can be obtained if this end is attached to the moving load rather than the fixed end of the tackle. Various types of blocks are used in sailing. Some blocks are used to increase mechanical advantage and others are used simply to change the direction of a line. A ratchet block turns freely when a line is pulled in one direction but does not turn the other direction, although the line may slip past the sheave. This kind of block makes a loaded line easier to hold by hand, and is sometimes used on smaller boats for lines like main and jib sheets that are frequently adjusted. A single, large, sail-powered warship in the mid-19th century required more than 1,400 blocks of various kinds and sizes. An item from an old sailing vessel from the late 19th to early 20th century, unfortunately, the item cannot be identified as to what vessel it belonged to. It does however give an insight into a piece of sailing equipment that's design is still in use today on pleasure sailing craft. Wooden closed spelter double rope block with two pully's between sheaves, block has metal frame around outside of the sheaves and 4 metal pins, 2 each side of the frame at top and 2 at bottom, joining the sheaves together. The shaft between the sheaves is also wooden. Remnants of orange and black paint on outside of block. Shafts are chipped, wood has borer holes.

An auxiliary tool for use with a breast drill or bit brace, when extra power is needed, or where pressure cannot be easily applied. The drill is automatically fed into the work by an adjustable friction feed which is automatically regulated by the resistance the drill encounters. These were made to fit on breast drills, and used for drilling metal, particularly round sections like a pipe. The chain is run around the object being drilled and gradually tightens as the hole is drilled, maintaining pressure while being a bit easier on the operator. Millers Falls Co. is a tool manufacturing company originally based in Millers Falls, Massachusetts, USA. It was established in Greenfield, Massachusetts in 1868 as Gunn & Amidon by Levi J. Gunn and Charles H. Amidon. Gunn and Amidon, along with a third partner, Henry L. Pratt built a factory in the north of Greenfield. After the Greenfield factory burned down, the company was reorganized as the Millers Falls Manufacturing Co. It merged with Backus Vise Co. in 1872 to form Millers Falls Co. In 1931 Millers Falls tools purchased the majority of the shares of Goodell-Pratt tools and merged with that manufacturer in 1932. In 1962 the company was acquired by Ingersoll Rand. In 1982, Ingersoll Rand sold the Millers Falls business to the newly created Millers Falls Tool Co. The company was head quartered in Alpha, New Jersey. Since 2002 the company trademark has belonged to Hangzhou Great Star Industrial, of Hangzhou, China. The item is associated with a tool manufacturing company established in the mid-19th century that pioneered the development of many types of tools used in many differing trades. The company grew to become a major supplier of tools around the world and today its tools that were produced during the mid-19th and early 20th centuries are now collectable items.

This candle bracket was recovered from the wreck of the sailing ship Loch Ard after the to the disaster in 1878. The bracket has been hand forged into a pleasing shape and design. The candle holder on the arm of the bracket cn swivel from side to side allowing the light to be adjusted. LOCH ARD 1873-1878 – The Scottish-built clipper ship Loch Ard was bound for Melbourne in 1878 with 54 people on board. The mixed cargo it carried included items for the 1880 International Exhibition in Melbourne, one of which was the now famous Majorca ware Minton ‘Peacock’ statue. The Loch Ard was wrecked on June 1st when the ship crashed into Mutton Bird Island, east of Port Campbell. The only survivors were Tom Pearce, a crew member, and Eva Carmichael, a young passenger who was rescued by Pearce. The Gibsons, owners of nearby Glenample Homestead, cared for Tom, and for Eva who stayed longer before returning to Ireland. The wreck of the Loch Ard was discovered in 1967, before the introduction of the Victorian historic shipwreck legislation. In 1969 it was decided that all recovered material should be lodged with the Receiver of Wrecks. In 1980 Flagstaff Hill Maritime Museum Divers received a permit to recover artefacts from the wreck to safeguard them from looters. In 1982 the site was listed as a Historic Shipwreck, and the Maritime Archaeology Unit recovered loose artefact material. The candle bracket is an example of light fittings from the ship ‘Loch Ard’ or from part of the ship’s cargo, imported for use in Colonial Victoria in the 19th to early 20th century. Flagstaff Hill’s collection of artefacts from LOCH ARD is significant for being one of the largest collections of artefacts from this shipwreck in Victoria. It is significant for its association with the shipwreck, which is on the Victorian Heritage Register (VHR S417). The collection is significant because of the relationship between the objects, as together they have a high potential to interpret the story of the LOCH ARD. The LOCH ARD collection is archaeologically significant as the remains of a large international passenger and cargo ship. The LOCH ARD collection is historically significant for representing aspects of Victoria’s shipping history and its potential to interpret sub-theme 1.5 of Victoria’s Framework of Historical Themes (living with natural processes). The collection is also historically significant for its association with the LOCH ARD, which was one of the worst and best known shipwrecks in Victoria’s history.

This Gestetner Cyclostyle duplicating machine was invented and manufactured by David Gestetner. He claimed in 1922, once he had released several models, that if a Gestetner Durotype stencil was used together with his Cyclostyle machine, then 10,000 copies could be made from the one Durotype stencil, an amazing claim for office technology of that era. David Gestetner (1854-1939), was born in Csoma, Hungary. He has been called the “founder of the worldwide office copying and duplicator industry.). He moved to London and in 1879 filed his first copying patent. In 1881 he patented the Cyclostyle stylus (or pen), which was used in conjunction with his Cyclograph device for copying text and images, He established the Gestetner Cyclograph Company in England at this time (1881) to protect his inventions and to produce his products; stencils, stylos (stylus or pen) and ink rollers. HIs inventions included nail-clipper and the ball-point pen (although the latter is more commonly associated with Laszlo Biro). Gestetner’s patented Cyclograph duplicator was used with his Cyclostyle Stylus or pen to write or draw on special thin wax-coated stencil paper (originally used for kite making paper) in the following way; 1. The Cyclostyle stencil was placed on a lower, framed metal plate of the Cyclograph 2. An upper frame was clipped over the top 3. The Cyclostyle pen, with its tip being a small metal-spiked or toothed wheel, was used to write or draw on the stencil, punched small holes into the paper and removed the wax coating in those places 4. The upper frame and stencil was then removed and a piece of blank paper was placed onto the metal plate in the lower frame and the upper frame with stencil was replaced 5. A roller was given an even distribution of Cyclostyle ink and rolled by hand over the stencil in the frame. This forced the ink through the holes in the stencil to and made a copy of the stencil on the paper 6. The upper frame was raised, the printed paper removed and another blank sheet was put into place. The whole process was repeated until enough copies were made. Gestetner’s invention developed further in 1894, with a stencil that could be placed on a screen on a revolving drum. The drum was manually rotated, the stencil then wrapped around another drum and was fed between cloth-covered rollers on which ink was evenly spread. Each revolution of the drum forced ink through the holes in the stencil and transferred the ink onto paper that had been fed between rollers and pressed against the drum. The process was repeated for each page. The paper was still fed and removed manually in this earlier invention but became more automatic in later models. In 1902 Gestetner duplicator model 6 was put onto the market. This model included the improvement of an automatic paper feed that synchronised with the rotation of the stencil. The Gestetner machine was the first office printing machine. It was easily installed and it made exact copies of the sane document quickly, effectively and inexpensively. This changed the way offices operated, making information easily available to many more users. The machines were commonly used in small businesses, schools, churches, clubs and other organisations for the wide distribution of a wide variety of information in the form of worksheets, newsletters and more. In 1906 the Gestetner Works were opened in Tottenham Hale, North London, and thousands of people were employed there up until the 1970’s. Due to the fast growing success of the Gestetner Duplicator machines many international branches for sales and service centres were established. David Gestetner was succeeded by his son Sigmund, followed by his grandson’s David and Jonathan. Further advancement was made by using a manual typewriter with specifically designed stencils. The end product was a printed, typewritten copy similar to the print from newspapers and booklets. In the next few years there were further developments of this revolutionary invention. The Gestetner Cyclostyle duplicator in our Collection is dated c.1922 - 1929 and it uses Gestetner Durotype stencils The 1922 British Industries Fair’s catalogue contained advertising for the Gestetner Rotary Cyclostyle “The World’s Premier Duplicator”, demonstrated at Stand K 86.” A Notice at the foot of the advertisement’s page boasts "Important - D Gestetner's latest invention, the "Durotype" Stencil, enables you to obtain 10,000 copies from one original if desired. It contains no wax of any description, is indestructible, can be stored indefinitely and printed from as required” In 1929 the look of the Gestetner machines changed; American designer Raymond Loewy was invited by Gestetner to improve the look of his duplicators, resulting in a very streamlined appearance. Eventually, around 1960’s, offices replaced their Gestetner with small photocopying machines and printers. Gestetner took over ownership of other office machine companies over time, including Nashua, Rex Rotary, Hanimex and Savin and eventually all came under the holding company name of NRG (Nashuatech, Rex Rotary and Gestetner). In 1996 Ricoh acquired the Gestetner Company, and it was renamed the NRG Group.

The Olivetti company was founded in Italy in 1908.This particular typewriter is a Olivetti Lettera 22, oblique front stroke and portable manufactured after 1950. The 1950s and 1960s was a time when British manufactured goods were still purchased by many Australian consumers. The later 1960s onwards, there was a shift, mainly in the cities, to European made goods. The invasion of Japanese manufactured goods was relatively slower, especially in rural areas. The demand for long lasted and dependable merchandise was in the rural area still the most important criteria. The ease of setting up this typewriter and its compact mobility was its major benefit to trades people and travelling professionals, e.g. rural doctors, other medical professionals, accountants, lawyers and educators. This item facilitated the growing numbers of professional nomads requiring a relatively light office stationery package e.g. travelling novelist, writer, businessman and academics. This typewriter needed no electrical or battery power to operate it. Outback Australia, where at this point in time, was still relatively isolated from a good available electrical power reticulation and battery power, and therefore could not be totally measured as a highly efficient office environment.Although this typewriter was purchased from a business in Penrith, Sydney, N.S.W., it is significant that it travelled easily to the Kiewa Valley, demonstrating the mobility of certain sections of the community. This typewriter was designed by an Italian industrial designer, Marcello Nizzoli, in line with the art deco style of the 1930s and the colour and flexibility of the vibrant 1950s. The underlying theme of manufacturing in the 1950s was to produce equipment that was more efficient than what was inherited from the earlier period of 20th century. Improvements were made to this Olivetti typewriter by Giuseppe Beccio by reducing the number of parts made from 3,000 to 2,000. This reduction of parts and therefore cost of production was the major principle of the Japanese manufacturing juggernauts of the post World War II era. Efficiency and low costs material was becoming prime factors in the success of rural industries from the 1960s. Competition from overseas producers was starting to affect rural industries and the removal of the large range of tariff protection, especially rural products, required not only a shift of farm management but a more efficient cost savings modus operandi. This Olivetti Lettera 22, oblique front stroke portable (weighs 4kg) mechanical typewriter has a coral coloured plastic casing. The keys are made of black hardened plastic with white lettering, numbers and symbols (imperial fractions, and pound). It has a QWERTY keyboard as opposed to the Italian QZERTY. It has a lever to move the ribbon between black, neutral (for mimeograph stencils)and red colours (a red key is provided for highlighting specific words,letters or symbols) . This machine is fitted with only a black ribbon. It has a black rubber paper rollers and chromed metal parts on the carriage way. It has four rubber feet underneath the main body. On the left side of the roller there is a lever to adjust the roller from fixed (when mobile) through 1,2 and 3 line space gradients. This model has a key for zero but not one for the number one (uppercase letter l is used) see KVHS 0459 for the carrying bag.On the cover over the ribbon wheels letter strikers has a plate marked "Lettera 22" and the back plate behind the paper roller and in front of the paper supports has a silver metal label marked "olivetti made in great britain".commercial, mobile office equipment, mechanical typewriter

This is a set of eight photographs of technicians operating photogrammetric equipment in Air Survey Squadron, Army Survey Regiment, Fortuna, Bendigo. c1960s to c1980s. The Wild A9 Stereocomparator and Wild B9 stereo plotter were introduced in 1962. The Wild B8 stereo plotter was introduced in 1966. Technicians used the Wild A9 Stereocomparator to accurately measure between pass, tie, and survey control points on aerial photographs. The Wild B9 and B8s were used for plotting topographic detail and contours. These analogue machines were manually controlled by adjusting the control knobs for the orientation of the 3D image. The B9s used a four and a half square, and the B8s used a nine-inch square photo image on a film or glass diapositive which allowed highly accurate extraction of map features. At first, plotting with B8 and B9 stereo plotters was undertaken at the aerial photography scale of 1:80,000 in pencil onto a controlled plotting sheet. Sheets were then inked up and reduced photographically to the 1: 100,000 publication scale for scribe impression production. In the early days topographic detail and contours were plotted with a pencil or ink pen mounted at the far end of the pantograph arm. The plotting procedure was upgraded to direct plotting in ink with photographic reduction to publication scale. In 1975 four B8s were upgraded with tri-axis locaters as part of the Input Sub-system to enable digital extraction to AUTOMAP 1’s topographic database. When AUTOMAP 2 was introduced in 1982 these B8s were upgraded, and additional machines added to expand the Army Survey Regiment’s digital capture capability.

Anecdotal evidence holds that most men returned from Vietnam in the dead of night, hidden from the public. In fact, large numbers actually returned on HMAS Sydney, to a welcome by dignitaries and a parade. The manner of their homecoming affected the way in which veterans recovered from the war, those who did arrive late at night to no fanfare and the seeming indifference of the military had more trouble adjusting to life at home than did those whose return was more public and who had had the benefit of a couple of weeks unwinding on board Sydney before reaching Australia. But the return home was only the beginning of a long period of readjustment. For a long time after the war large numbers of Vietnam veterans felt that many in Australia blamed them, rather than politicians, for the war and the way it had been conducted. Images of the war, many still familiar, of children burned by napalm, of the dead of My Lai, of a South Vietnamese general summarily executing a member of the Viet Cong in the streets of Saigon, had an effect on public opinion and public understanding. The fact that these images related more to the American/Vietnamese experience in Vietnam was less remarked upon. People associated the role of Australians in the war with that of the Americans in a way that failed to recognise the two countries’ different approaches to fighting in Vietnam. see https://www.google.com.au/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&cad=rja&ved=0CDwQtwIwAg&url=http%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DYL06ddRmiJE&ei=O9OJUYnxC5GaiQeey4HQCA&usg=AFQjCNEjq876qAoYu0WnWslDSNRUJlmuBw&bvm=bv.46226182,d.aGc Wooden Plaque 15cm x 13cmVietnam Vererans Parade Sydney 1987

A spokeshave is a hand tool used to shape and smooth woods in woodworking jobs such as making cart wheel spokes, chair legs, paddles, bows, and arrows. The tool consists of a blade fixed into the body of the tool, which has a handle for each hand. Historically, a spokeshave was made with a wooden body and metal cutting blade. With industrialization metal bodies displaced wood in mass-produced tools. Being a small tool, spokeshaves are not suited to working large surfaces. The name spokeshave dates back to at least the 16th century, though the early history of the tool is not well documented. The name spokeshave reflects the early use of the tool by wheelwrights. The first spokeshaves were made of wood usually beech with steel blades, before being largely superseded by the development of metal-bodied spokeshaves in the latter half of the 19th century, though many woodworkers still use wooden spokeshaves. Due to their widespread use and versatility vintage wooden spokeshaves remain commonly available and relatively low in price. Spokeshaves consist of a blade or iron secured to the body or stock of the tool, which has two handles one for each hand. The bottom surface of the tool is called the sole. The blade can be removed for sharpening, and adjusted to vary the depth of the cut. An early design consisted of a metal blade with a pair of tangs to which the wooden handles were attached, as with a draw knife. Unlike a draw knife, but like a plane, spokeshaves typically have a sole plate that fixes the angle of the blade relative to the surface being worked. There are a wide variety of different types of spokeshave, suited to different trades and applications. A now vintage tool made by an Australian manufacture in NSW who specialised in making pruning shears, hacksaw frames and heel shaves under the Erskin brand name. This tool is now sought after by collectors even though it was probably made in the first quarter of the 20th century. It gives a snapshot of how carpenters work with wood by hand showcasing their craftsmanship. Hollow face Spokeshave, metal body with black enamel finish.

The Bow Tie is a type of men's necktie that consists of a ribbon of fabric tied around the collar in a symmetrical manner such that the two opposite ends form loops. Ready-tied Bow ties are available, in which the distinctive Bow is sewn and a band goes around the neck and clips to secure. Bow ties may be made of any fabric material, but most are made from silk, polyester, cotton, or a mixture of fabrics. The Bow tie originated among Croatian mercenaries during the Prussian wars of the 17th century when the Croat mercenaries used a scarf around the neck to hold together the opening of their shirts. This was soon adopted under the name cravat, derived from the French for "Croat", by the upper classes in France, then a leader in fashion, and flourished in the 18th and 19th centuries. The most traditional Bow ties are usually of a fixed length and are made for a specific size neck. Sizes can vary between approximately 14 and 20 inches just like a comparable shirt collar. Fixed-length Bow ties are preferred when worn with the most formal wing-collar shirts, so as not to expose the buckle or clasp of an adjustable Bow tie. Bow ties are worn by magicians, country doctors, paediatricians, lawyers, professors musicians and by people hoping to look like the above and clowns also wear oversized ones. In the 1980’s fashionable and professional women wore a type of Bow tie. Most men only wear Bow ties with formal dress.

The first commercial digital hearing aid was created in 1987 by the Nicolet Corporation. The hearing aid contained a body-worn processor that had a hardwire connection with an ear mounted transducer. While the Nicolet Corporation’s hearing aid was not publicly successful and the company shortly folded, it was able to start a competition between companies to create more effective hearing aids. Two years later, in 1989, the behind-the-ear (BTE) digital hearing aid was launched. In addition to the Nicolet Corporation, Bell Laboratories expanded upon the hearing aid business by developing a hybrid digital-analog hearing aid. When the hearing aid was put on in the market, it was instantaneously successful. This development helped bring major changes to the world of the hearing aid. The next major milestone was creating an all-digital hearing aid. The Oticon Company developed the first digital hearing aid in 1995, but it was only distributed to audiological research centers for research on digital technology in the realm of acoustic amplification. The Senso was the first commercially successful, all-digital hearing aid, and was created by Widex in 1996. After the success of the Senso, Oticon began marketing their own hearing aid, the DigiFocus. Presently, the digital hearing aid is now become programmable. By making the hearing aid programmable, it has allowed hearing aids to be capable of regulating sound on their own, without using a separate control. The hearing aid can now adjust itself depending on what environment it is in and often does not even need a physical volume control button.

Retrieved from crashed (during W.W.2) Avro Anson aircraft at Propeller Bay near Lady Julia Percy Island in 13 metres of water. Found adjacent to the remains of the engine and propeller in June 1993 by Peter Ronald. It was possibly used to adjust control cables. The plane went down on the 15th February 1944 Flight Sgt. J.H. MacLellen, Flight Sgt D.l. Baulderstone, LAC N.T. Kruck, LAC B.C. Ladyman were killed. A memorial was erected at the 'Crags' on the 14th of February 2015 . " At 0800 Anson AW878 of 2AOS took off from Mount Gambier to carry out a radius of action navigation exercise to Lady Julia Percy Island (located off the Victorian coast, midway between Portland and Warrnambool) and back to Mount Gambier. By 1230 it was overdue, and that afternoon a search was instituted. No radio messages had been received from the Anson, although it had been seen during the exercise by another aircaraft. At 1430 part of the mainplane was sighted on Lady Julia Percy Island. Subsequently a fishing boat searched in the vicinity of the island and passed through small pieces of wreckage strewn over about 3 miles. A further search uncovered wreckage which identified the plane beyond doubt, including fuel tank bay cover with AW878 penciled on it, and a Mae West which had been signed out by one of the crew. The bodies of the four crew were never located."
