Australian scientists have reported potential indicators of H5 avian influenza, commonly known as bird flu, in wildlife on Heard Island, which is located in the sub-Antarctic region. These observations were made during a management expedition to the island.
Although the suspicions regarding the presence of the virus have not yet been confirmed, the Department of Agriculture, Fisheries and Forestry (DAFF) emphasizes the importance of remaining vigilant in preparation for any potential outbreaks.
Heard Island is part of the remote Heard Island and McDonald Islands, an external territory of Australia. This territory is situated more than 4,000 kilometers southwest of Perth and approximately 1,700 kilometers north of Antarctica, within the Southern Ocean.
A confirmed detection of H5 avian influenza on Heard Island would not significantly heighten the risk to mainland Australia. Currently, Australia stands as the only continent free from this highly contagious strain of bird flu.
As avian influenza can have serious implications for both wildlife and poultry industries, the findings underscore the necessity for continued monitoring and preparedness against potential outbreaks in the region.
