Authorities in Australia confirm the first mass deaths linked to H5N1 avian influenza after a seagull and dozens of terns test positive for the virus. Multiple outlets report that wild birds in affected areas are dying in greater numbers, prompting public health and biosecurity warnings. The reporting emphasizes that the detection is an initial event and may indicate broader risk to bird populations. Australians are urged not to touch, approach, or feed wild birds, including seabirds. People are advised to avoid contact with carcasses and to keep pets away from sick or dead wildlife. The news coverage also highlights that the confirmed cases involve birds found dead, with the positive test results used to link the deaths to H5N1. All sources present the same core message: confirmed H5N1 presence in wild birds and precautionary guidance to reduce the chance of exposure while monitoring and investigations continue.
