How about a journey back to World War II? It involves radio waves and secret communications at the HF Transmitter Facility WWII. This unassuming site played a crucial role in Australia’s war effort.
During World War II, the Australian Army established a large HF wireless telegraphy communications station. This facility was strategically split. The receiving station was in North Ringwood. The transmitting station was near Coldstream.
Now, picture this. The unstaffed transmitting station hummed with activity near Coldstream. It housed several rhombic antennas. An antenna switching panel stood ready. Five HF high-speed W/T transmitters were in constant use. The location was in the yard of a property called St Huberts in St Huberts Road.
These antennas were specifically designed. They optimized radiation to key locations. Alice Springs, New Zealand, Darwin, Hobart and Chungking in China were all important destinations. The transmitting towers stood north of the airfield. They were on the Yarra River Flats in Tarrawarra Rd. The towers were not far from today’s Coldstream airport.
International radio communications were vital during the war. They underpinned command and control. The HF Transmitter Facility WWII helped secure Australia’s communications.
After the war, the HF Transmitter Facility WWII was dismantled. The receiving equipment moved to Rockbank. The transmitting equipment relocated to Deer Park. Both sites were in Melbourne’s outer west.
Photos from May 1943 capture the HF Transmitter Facility WWII. These images reside at the Australian War Memorial in Canberra. You can view them online. Search for “ringwood radio” for the receiving station. Search “coldstream radio” for the transmitting station.
Imagine the Morse code operators. They tirelessly sent and received messages. The HF Transmitter Facility WWII was a vital link. It connected Australia with the world during a time of great peril.
Today little remains of the HF Transmitter Facility WWII. Yet its story endures. It reminds us of the ingenuity and resilience. It is an important part of Australia’s wartime history. The facility played a significant role in global communications during a critical period. As you explore this area, remember the silent work. Remember the vital communications that once pulsed through the air. This is the legacy of the HF Transmitter Facility WWII.
