Wireless Hill is on the land of the Beeliar residence group of the Whadjuk Noongar people,[1] who have lived in the area for millennia.

Clearing of the site and construction began in 1911, with the Applecross Wireless Station completed and officially opened on 30 September 1912.

)[15]: 117 [2] In 1970 the West Australian VHF Group (an amateur radio club) proposed establishing a telecommunications museum.

[1] In 1974 work began on converting the station, and in 1979 the Wireless Hill Telecommunications Museum was officially opened[2] as a contribution to Western Australia's sesquicentennial celebrations.

[16][17] Wireless Hill Park was classified by the National Trust of Australia in 1992,[1][2] and listed on the Western Australian Register of Heritage Places in 1997.

[1][11] When the station opened in 1912 it used a 25 kW quenched spark-gap transmitter manufactured by Telefunken, and a receiver with a locally built crystal detector (using galena from Northampton).

[1] In 1927 a shortwave "beam system" was installed, which extended the transmission range sufficiently to allow direct communication between Australia and England.

This included transmission of weather forecasts, news bulletins and time signals, sending medical advice to ships with no doctors aboard, and monitoring for distress calls.

[1][29] Western Australia's first commercial radio station, 6PR, was broadcast from Wireless Hill between 1931 and 1950, relayed from a studio in Barrack Street.

[1][2] In the 1960s the station provide communications to the US rescue aircraft that flew continuously over the Indian Ocean when NASA were conducting a Mercury mission.

[35][36] It is listed as site 336 on "Bush Forever",[34][37] a state government policy to protect regionally significant bushland.

[38] Much of the area was cleared when the Applecross Wireless Station was originally built[39] or shortly afterwards during World War I for security reasons.

[7] The park includes a scarred tree, used by Indigenous Australians to create utensils or shields, or to mark territory.
