IARU Region 3 includes the member societies representing amateur radio operators in Australia, most of Asia, and the Pacific Islands.
Although they represent a broad range of amateur radio interests in their nations today, several member societies of the International Amateur Radio Union were originally formed for the promotion and organization of the sport of ARDF and continue to use the term radiosport in their society name.
•
At least two specific contests have used the term radiosport in their event names; the IARU HF World Championship, a worldwide contest sponsored by the International Amateur Radio Union, was known as the IARU Radiosport Championship from its inception in 1977 until the name of the contest changed in 1986.
