Australia has confirmed its first mainland case of the deadly H5N1 bird flu strain, detected in a migratory seabird on the Western Australian coast. Prime Minister Anthony Albanese described the development as 'concerning' but assured that the government had prepared for such an event.
Confirmation of the Case
Agriculture Minister Julie Collins announced that a brown skua, found unwell last Sunday at Cape Le Grand National Park near Esperance in southern Western Australia, had died from H5N1. Tests also suggest a sick giant petrel found in the same area may be infected, with samples sent to the CSIRO for confirmation.
Government Response
Collins promised a nationally coordinated response, initially focusing on determining the extent of the disease's spread in wildlife. 'We will know within a few days whether this has established itself in any populations in Australia, or if it's from migratory birds,' she said. There is no evidence of mass mortalities or infection in poultry so far.
Prime Minister Anthony Albanese stated that the government's first priority is to 'restrict the spread.' He noted that Australia has spent $113 million in preparation and is working to limit the impact. 'This is something that has happened through migratory birds. It's happened around the world, and that is why we've been preparing for this,' he said.
Impact on Wildlife
BirdLife Australia CEO Kate Millar stressed the potential significance for Australian wildlife. 'This virus has devastated wildlife populations overseas. This could be the beginning of a long fight to protect birds and wildlife in Australia,' she said.
Chief Veterinary Officer Beth Cookson said the Western Australian government is conducting on-ground surveillance to investigate if the disease is present in wild native bird populations. She advised the public to avoid contact with sick or dead birds, take a photo, and report the location to authorities.
Threatened Species Commissioner Fiona Fraser noted that governments have analyzed which species are most susceptible, including the Tasmanian devil, orange-bellied parrot, black swan, Australian fur seal, and sea lion. Over 100 response plans have been developed for at-risk animals and important natural sites.
Global Context
The highly pathogenic strain has killed millions of birds globally and crossed into mammal species, including elephant seals. Until this week, Australia was the only continent to have escaped the devastating strain. The disease was detected on the remote subantarctic territories of Heard Island and McDonald Islands in October last year, where thousands of elephant seal pups and hundreds of king penguins have died.
Collins said the community should be alert and prepared for the possibility that other birds and mammals could be affected. A meeting of the consultative committee for emergency animal disease discussed response measures, including increased surveillance.
