H5N1 Bird Flu Reaches Australia, Triggering Urgent Wildlife Surveillance

Australia confirms the first detections of the highly pathogenic avian influenza H5N1 (clade 2.3.4.4b) in two seabirds off Western Australia, marking the virus’s arrival on the continent. The strain, now circulating globally, spreads rapidly and has devastated wildlife and poultry elsewhere, though human risk remains low. A national taskforce has been preparing since 2024, expanding surveillance and biosecurity, with discussions of wildlife vaccination in extreme cases. The public is urged to report sick or dead birds to authorities and avoid contact with wildlife to help containment.
