Australia has confirmed a rapid spread of the H5N1 avian influenza virus among wild birds, with 74 cases reported and the total number of confirmed or presumed positive detections rising to 175 across multiple states. The outbreak has caused mass mortality events, notably at Baudin Rocks, and has moved into resident seabird colonies on the Limestone Coast of South Australia.
A seal pup found on Warrnambool appears to be the first mainland case of the virus in a marine mammal, raising concerns for seal populations near endangered sea‑lion colonies. Volunteers and wildlife groups, such as the Friends of Griffiths Island led by Tracey Gray, warn that local bird colonies, including greater crested terns and short‑tailed shearwaters, may be unable to absorb the impact.
The Australian government is coordinating a biosecurity response through bodies like the Consultative Committee on Emergency Animal Diseases and the National Management Group, while also exploring pilot vaccination studies in non‑poultry birds. New Zealand has already vaccinated 300 breeding birds of five endangered species, prompting debate over the feasibility of similar programmes in Australia. Experts stress the need for surveillance, habitat protection and coordinated action to prevent further ecological loss.
