H5N1 avian influenza spreads through Australian wildlife
The H5N1 avian influenza strain is spreading rapidly through wildlife in southern Australia, following its initial detection in migratory seabirds in June 2026. The outbreak has caused significant mortality among wild birds and has begun impacting marine mammals. In a historic first for the country, a common dolphin was found dead from the virus in Goolwa, South Australia.
In addition to cetaceans, the virus has infected long-nosed fur seals and a red fox. Experts warn that the outbreak may spread inland via waterfowl, potentially exacerbated by El Niño-driven droughts that concentrate birds at dwindling water sources. To mitigate risks to personnel, the Australian government has evacuated researchers from Macquarie Island.
While the virus is affecting various wildlife species, authorities report that H5N1 has not yet been detected in Australian poultry or the domestic agricultural production system. Biosecurity measures are being recommended for backyard poultry owners to prevent spillover from wild bird populations.
