Australia's wildlife faces mass deaths as H5N1 bird flu spreads

H5N1 bird flu Australia wildlife mass seabird deaths species risk assessment vaccination policy

Australia has confirmed its first large‑scale wildlife mortality event linked to the H5N1 avian influenza virus, with 49 dead greater crested terns and dozens more sick birds found at Baudin Rocks on the southern coast. The outbreak now includes more than 100 wild seabirds across five states and over 80 confirmed cases nationwide. A federal risk assessment of more than 2,000 native species identified nearly 400 birds and mammals as high‑risk, including the Christmas Island frigatebird, little penguin, Australian sea lion, Tasmanian devil and several seal species. Five species are rated extreme risk, meaning they are unlikely to survive where the virus spreads. The government has pledged $113 million for bird‑flu preparedness, of which $47 million is earmarked for protecting threatened wildlife, while the Invasive Species Council is urging a $200 million wildlife‑resilience package. Experts note that vaccination can be used for rare birds but current policy excludes marine mammals, and no infections have been detected in commercial poultry farms. Authorities are expanding surveillance, biosecurity measures and community outreach to curb further spread.
