History

In 1924, the Imperial Defence Committee's Communications Sub-Committee examined Australian coastal radio stations, and recommended the modernisation of the stations at Darwin, Perth, Rabaul, and Townsville. A year later, the Australian Commonwealth Naval Board

 (ACNB) made a recommendation that two wireless stations be provided for the Navy in Canberra and Darwin. These would be strategic stations in addition to the coastal stations. Canberra was chosen as its distance from the coast would increase its protection from attack. Planning continued in 1935, where a new Canberra station would add to the coverage area of Rugby

, approximately 20 kilometres (12.4 mi) north-west of the main receiving facility.

Construction of the transmission facility (Royal Australian Navy Wireless/Transmitting Station Canberra) commenced in November 1938. The facility established on 20 April 1939 and started transmitting on 22 December 1939. Work on the main facility started in early 1939, with the facility registered with the Postmaster General's Department on 20 July 1939 under the name 'Harman'. The name was derived from from the surnames of the two officers responsible for naming the new naval stations: Commander Neville Harvey of the Royal Navy

, and RAN Lieutenant Commander J.S. Newman. As the ACNB had paid little attention to the proposals for the names of previous wireless stations before implementing them, the two men proposed their combined names for the Canberra facility, which was accepted without comment.

World War II commenced before the station was completed. Newman was promoted to Commander and assigned to command the Harman facility from when it opened until 1941, when he was replaced as Officer-in-Charge. The station was commissioned into the RAN as the stone frigate

 hut located 1.2 kilometre (0.745647283979768 mi) away on a ridge, cottages and guard houses. Later, Number Two Receiving station was built for 'special tasks', a recreation hall was opened 27 April 1941, and a mess hall was finished around the end of 1940. In 1943, a second mess was built. The Morgan Dunbar Oval and Sir Victor Smith Oval are located in Harman. There are also tennis courts and a gymnasium. The base covers an area of 2.5 sqkm. 970 people work at Harman, and 25 families are in permanent residence.

Functions performed at HMAS Harman include:
  • Naval Communications Area Master Station Australia (NAVCAMSAUS); supports and tasks Navy fleet communications
  • Naval Communications Station Canberra (NAVCOMMSTA Canberra); provides UHF satellite communications for the Australian Defence Force
  • Defence Information Systems and Communications Establishment - ACT (DISCE-ACT)
  • Defence Network Operations Centre (DNOC)
  • Two units of the Army Reserve
  • Administrative and personnel support
  • Naval Police Coxswain's office
  • Australian Naval Reserve support

 transmitter. The station was equipped with 40 kW and 10 kW HF transmitters that used a variety of antennas including rhombic, vertical monopole, and log-periodic antennas. The station was initially built with small cottages flanking the eastern side of the site, housing the electrical engineer-in-charge and the sailors who maintained the transmitters and antennas. These were removed in the late 1980s, although the mess building remained, with personnel moving into housing in the growing suburbs that gradually encroached on the site. The station ended transmissions on 1 June 2005, and the remaining structures on the site were demolished in December 2006 to allow for residential development on the site, forming the new suburb of Lawson
