Australia confirmed its first mainland case of the H5N1 bird flu strain in a migratory sea bird found in the southwest of Western Australia. Prime Minister Anthony Albanese stated the government would do "whatever we can to restrict any spread." Testing confirmed the virus in a brown skua found near Esperance, a town approximately 570 km southeast of Perth. The detection means the highly pathogenic avian influenza has now spread to every continent. Agriculture Minister Julie Collins noted that there is no evidence of mass mortalities or infection in Australia's poultry or agriculture systems at this stage. A second sick bird, a giant petrel found in the same area, also tested positive. Australia has been enhancing biosecurity measures, testing shore birds, vaccinating vulnerable species, and war-gaming response plans in preparation for the virus's arrival.
