Australia confirms local spread of H5N1 bird flu in wild birds

Australia H5N1 bird flu wild birds Kangaroo Island

Australia has confirmed that the highly pathogenic H5N1 avian influenza strain is now locally transmitting among wild birds. Since its first detection in June, 27 confirmed infections have been recorded in seabirds, shorebirds and waterfowl across Western Australia, South Australia, New South Wales and Queensland. The first Victorian case was identified in a greater crested tern found dead near Portland.

State and federal authorities have activated emergency animal disease response plans. Victoria’s Chief Veterinary Officer Graeme Cooke announced the enactment of the State Emergency Animal Disease Response Plan and issued bio‑security advice to farmers and the public. Health officials say the risk to humans is low and no H5N1 virus has been found in commercial poultry.

In South Australia, 11 new suspected cases were reported, including four on Kangaroo Island. Guided beach tours on the island have been suspended to protect the endangered Australian sea‑lion colony at Seal Bay. A silver gull tested positive in a suspected case, which the Invasive Species Council described as a “watershed moment”.

Officials warn the virus could threaten vulnerable wildlife, especially sea‑lion pups, and have called for a national wildlife‑resilience fund. Surveillance and reporting continue nationwide.
