... and broadcast radio, Morse, and light signals. The survival of the Uiver ...This telegram was sent from the Royal Netherlands Airways, Sydney, to the manager of ABC Radio Station 2CO, Corowa, New South Wales. This telegram relates to the 1934 London to Melbourne Air Race. The telegram records the Royal Netherlands Airways' thanks to ABC Radio 2CO radio staff for their efforts in broadcasting an emergency message to the residents of Albury after the Dutch airliner ‘Uiver’ became lost at night in bad weather. As requested local radio listeners drove their cars to the Albury racecourse and illuminated an emergency landing ground using their vehicle headlights. This allowed the lost airliner to land safely.This item relates to the London to Melbourne Air Race of 1934, a significant event that shaped Australia's history as it proved travelling to and from Australia could be done within a reasonable time by air, thereby making the country less isolated. Up to that time Australia was three weeks away from Europe by steam ship. The Air Race was dreamt up by the Lord Mayor of Melbourne, Harold Smith, to commemorate the centenary of Victoria's statehood and was sponsored by the Melbourne chocolate manufacturer Sir MacPherson Robertson. The Royal Netherlands Airways entered a Douglas DC2 plane 'Uiver' - the largest aircraft in the race, and the only one to carry passengers as well as crew, to show that a commercial passenger service to Australia was possible. But in the last leg of the race, the Uiver lost its way in an electrical storm over the Riverina town of Albury. Several communication methods were used to land the plane safely, including the signalling of the word "Albury" in Morse code using the town's street lights. Local ABC Radio station 2CO also made a call for locals to light up a makeshift landing strip for the plane at the town's racecourse. The plane landed safely and the next morning with the help of the townspeople who pulled it out of the mud, took off and finished the race in second place. The story of the Uiver points to the importance of communication in its various forms: two-way and broadcast radio, Morse, and light signals. The survival of the Uiver is a reflection of the ingenuity of Australian communications and the solutions that can be found through the sharing of ideas of information. The landing of the Uiver was an important moment in Albury's social history, as residents participated in the rescue of the plane and its passengers, helping the Uiver to continue on its journey and finish second in the Race. When the Uiver crashed in the Syrian Desert in December 1934, Albury residents contributed to a memorial which honoured those who were killed. Beige paper telegram printed with black ink and overwritten with typewriter. Telegram split into sections designating details of the telegram, details of the recipient and a space for the transmitted message.

Parks Victoria - Wilsons Promontory Lightstation
Lamp, Aldis
The lamps were pioneered by the British Navy in the late nineteenth century and introduced by the Royal Australian Navy after 1918, and continue to be used to the present day. Manufactured in 1960, the Wilsons Promontory lamp was provided to the lighthouse by the Department of Shipping for signalling ships but was also used for communicating with Cliffy Island, 18 nautical miles away. This type of lamp was renowned for its brilliant light, and lightkeepers from the two lightstations ‘used to practice their signalling with each other, as its effective use was reliant on precise positioning of the scope which is located on top of the lamp’. The inside of the case is imprinted with ‘RAN (Royal Australian Navy), and details on the lamp include a serial number, the date of 1960 and the initials of the Department of Transport, which at that time incorporated the Commonwealth Lighthouse Service. Another Aldis lamp and case with a date of 1960 is held at Cape Nelson and third lamp and case is at Point Hicks; (date unconfirmed but possibly 1943). A fourth lamp and case formerly at Cape Schanck disappeared from the collection sometime between 1995 and 2003.Aldis lamp and case (WPLS 0003.2; likely provenance) The lamps are not rare in museum collections however the Wilsons Promontory example has a confirmed provenance to the lightation and has first level contributory significance as a fine example of the Aldis lamps that were distributed to lightstations throughout Victoria and Australia.1.

Parks Victoria - Cape Nelson Lightstation
Instrument - Morse Code Key Set
The battery powered set, which dates from the second half of the twentieth century, comprises two main components, the electronic keyer with a single lever for tapping, and a transmitter (?), both connected by a keying cable. Morse code was invented in the 1830s by American, Samuel Finely Breese by using electrical signals to quickly transmit information over a long range. In the early 1890s Italian inventor, Guglielmo Marconi improved the technology to the point where it became an essential device used for commercial and government purposes. The first practical applications were demonstrated with maritime messaging, where this simple mode of communication was seen as a timely replacement for the historic practice of signaling by flags, lights and foghorns. Cape Schanck has an earlier Morse code key, which is original to the lightstation (CSLS 0035), and Cape Otway has another early example although its provenance to the lightstation has not been formally verified (COLS 0074). The Morse code set has first level contributory significance for its historical value as an earlier communications device that has since been made redundant by more sophisticated technologies.Morse code key set.

Parks Victoria - Cape Nelson Lightstation
Instrument - Lamp, Aldis
This portable, hand held visual signaling lamp, with trigger mechanism and inner reflective disk, was used for optical communication via Morse code, with the concave mirror tilted to focus the light into pulse signals. Larger versions of these lamps are fixed on ships or pedestals and have shutters in front of the light that are opened and closed to transmit signals. Smaller hand held versions like the Cape Nelson example have a concave mirror that is tilted to focus the light into pulse signals, and despite their size the lamps were renowned for their brilliant light. Invented by Arthur C W Aldis (1878‐1953) and pioneered by the British navy in the late nineteenth century, they continue to be used to the present day. Details on the Cape Nelson lamp include a serial number, a date of 1960 and the initials of the Department of Transport, which at that time incorporated the Commonwealth Lighthouse Service. Another lamp of the same date which is held at Wilsons Promontory was provided to the lighthouse by the Department of Shipping for signaling ships but was also used for communicating with Cliffy Island, 18 nautical miles away. Point Hicks also has an Aldis lamp and an associated case, which is painted an army green colour. A fourth lamp and case formerly at Cape Schanck disappeared from the collection sometime between 1995 and 2003. These types of lamps are not rare in museum collections.These types of lamps are not rare in museum collections however the Cape Nelson example has a reliable provenance to the lightstation and has first level contributory significance as a fine example of the Aldis lamps that were distributed to lightstations throughout Victoria and Australia.This object is comprised of a black metal encased Aldis lamp with electrical cord and associated wooden carrying case with metal clasp and red leather hand grip. yes -
