In 1977, The United States and Australian governments agreed to establish an OMEGA navigation system in south-eastern Australia.

[3] Station G was an Omega transmitter that used an umbrella antenna carried by a 432 metres (1,417 ft) tall grounded lattice steel guyed mast.

Rather, the tower was electrically insulated from the topmost guys which served as the radiators, similar to the metal radials of an umbrella without cloth covering.

[10] After the shutdown of the OMEGA navigation system on 30 September 1997, the station was used as a transmitter for uni-directional communications to submarines on 13 kHz under the callsign VL3DEF until 2004.

[13] Transmission equipment from the Omega navigation system is now on display at the Port Albert Maritime Museum.
