We had a doctor, a pilot, a plane and a man with vision but we lacked the communication technology to deliver our services efficiently. Alfred Traeger helped us to hurdle this barrier with the invention of a pedal-operated generator to power a radio receiver. By 1929 people living in isolation were able to call on the Flying Doctor to assist them in an emergency.
Transistorised receivers later replaced pedal radios, making it possible for doctors to give radio consultations. It also meant neighbours, families and friends, scattered over thousands of kilometres, could exchange news and gossip after normal transmission hours. This time became known as the 'galah' session, aptly named after the noisy, chattering bird.
Using the Flying Doctor Service network, the School of the Air was established in Alice Springs in 1951. This radio service provided children living in remote areas the opportunity to interact with other children, ask questions of their teacher and supplement their correspondence lessons.
