Aero Linx: Recreational Aviation Australia (RAAus) Recreational Aviation Australia is the country’s largest administrator of pilots, maintainers and aircraft. Formerly the Australian Ultralight Federation (AUF), RAAus was established in 1983 and since that time we have consistently seen growth, diversification and improvements in our performance. We changed our name from the AUF to Recreational Aviation Australia Inc. in 2004 and in 2016 we changed our governance structure from an Incorporated Association to a Company Limited by Guarantee. We are now Recreational Aviation Australia Limited (RAAus).
