Deadly bird flu strain a ‘serious concern’ for wildlife - Canberra CityNews

Australia long-held status as the sole continent free of the highly pathogenic H5N1 bird flu has ended with the first confirmed mainland case in a migratory brown skua found in Western Australia. This alarming discovery, along with a second suspected positive in a giant petrel from the same area, has triggered a national alert, casting a stark spotlight on the devastating global spread of this deadly virus and its potential impact on Australia unique wildlife. This incursion follows months of heightened concern after the H5N1 clade 2.3.4.4b strain ravaged populations on Australia remote Heard Island in late 2025, wiping out thousands of southern elephant seal pups and hundreds of penguins. Globally, this particular HPAI strain has caused unprecedented mass mortalities across over 560 wild bird species and more than 100 mammal types, including marine mammals, since 2021, even infecting dairy cattle in the US. While the risk of human transmission remains low and primarily linked to direct animal contact, the virus's demonstrated ability to jump species barriers fuels ongoing pandemic preparedness concerns. Prime Minister Anthony Albanese has labeled the situation 'concerning,' assuring a nationally coordinated response with an immediate focus on extensive surveillance to map the virus's potential spread within Australia native ecosystems. Federal Agriculture Minister Julie Collins confirmed efforts are underway to determine if the virus has spread beyond these initial seabird detections, with authorities urging the public to report any sick or dead birds to emergency hotlines while observing strict biosecurity protocols. The coming days will be crucial in understanding the scale of this new environmental challenge and the immediate steps to protect Australia biodiversity and vital poultry industry.
