A sero epidemiological study was carried out on human sera from all regions of New South Wales for the presence of antibodies to nine bunyaviruses viz Aino, Akabane, Belmont, Gan Gan, Kowanyama, Mapputta, Peaton, Tinaroo, Trubanaman and the orbivirus Corriparta. Neutralising antibodies were found in titres up to 1280 to Gan Gan and to 640 to Trubanaman viruses, prevalences 4.7% and 1.4% respectively. Neutralisation titres up to 40 were found to Belmont, Aino, Peaton and Corriparta viruses but the significance of these is uncertain since they may represent either non‐specific inhibitors or cross reacting antibodies to related but currently unknown viruses. No antibodies were found to Akabane, Kowanyama, Mapputta or Tinaroo viruses in New South Wales sera. Gan Gan virus appeared to be pathogenic for man being associated with an acute epidemic polyarthritic like illness. Trubanaman virus is suspected of being pathogenic. This is the first report of the pathogenicity of these Australian bunyaviruses.
