The Postmaster-General's Department (PMG) was a department of the Australian federal government, established at Federation in 1901, whose responsibilities included the provision of postal and telegraphic services throughout Australia. It was abolished in December 1975 and replaced by the Postal and Telecommunications Department. Telephone calls were transferred through exchanges by manual operators who staffed switchboards throughout the country. The clock was used to time calls in order to levy appropriate charge for telephone usage.The use of manual telephone exchanges played an important role in Australian telecommunications history, not just for day -to-day business and commercial use, but for social connections and communication during emergency. This timer has local significance as it was used at the Wodonga Telephone Exchange.A small clock used by switchboard operators to time calls at the Wodonga Telephone Exchange.

Scythes were used to manually mow wheat or grass. Scythes were used with a long sweeping movement which made them much less tiring for labourers to use than reaping hooks or sickles though they still involved great physical labour and considerable skill to perfect. Both hands were in use and the operator did not have to bend his back to reach down to the crop. On farms scythes were sharpened on a sandstone wheel mounted on an axle with a crank handle on one side. This was hand powered and used with water. Scythes were not used as often on farms after the mechanisation of harvesting. They were still used for cutting awkward shaped small plots and for opening a path for the tractors. This item is an example of a tool used by the early settlers of the Orbost district. An iron scythe blade, curved and tapered. There is no handle and the blade is rusted and pitted."ROSE"scythe tool agriculture rural

This manual telephone exchange console is an important piece of equipment which provided the most efficient method of long distance communications in the 1950's to the 1980's. Communications were critical, not only for the regional Hospital, but also for large construction sites i.e. the Kiewa Hydro Scheme, especially if they are in dense rugged mountainous regions. The degree of Occupation Health and Welfare on industrial sites were at a bare minimum compared to the work scene after the 1980's.This telephone exchange console is highly significant to both the Kiewa Valley and Mount Beauty region because it was so important in the communications field relating to operational safety and work related controls. The success of any large undertaken relies heavily upon good communications. In the hospital this method of communications is still used i.e. patient to ward station. This flag system link a patient's room to the controlling nursing station. Identification of the patient needing help is crucial for swift action from the available medical staff. Similarly in large construction sites such as the Kiewa Hydro Scheme, successful instant communications was also essential. This switchboard required a 50 volt supply to successfully operate and was in use when both telecommunications and postal were under the one Federal Government carrier i.e. The Post Master General. A benefit with a line communication system (such as the one that fed this console was that interference from atmospheric conditions did not impede the connection.This console telephone switchboard (manual) unit has a shutter operation (precursor to the light indicator) to identify the caller to the telephone switchboard operator. This switchboard has a ten point indication shutter system allowing the operator to clearly identify where the caller is located. The console has a 44 connection point holes with their configurations in a triangular shape. The shutters are held closed by a small lever at the top which is opened by a small electrical charge from the incoming call. The operator uses a wind up handle to power a magneto connector(handle on the console's right side). The telephone hand set is located on the left side of the console. sec vic kiewa hydro scheme, alternate energy supplies, alpine population growth and communications
