The H5N1 strain of avian influenza has been detected in Australia for the first time, according to the Australian Department of Agriculture, which announced the finding on Saturday. This arrival means that the highly contagious variant is now present on every continent.
Agricultural Minister Julie Collins confirmed that the pathogen was identified in a migratory bird washed up on a secluded beach in southwest Western Australia. Specifically, a Brown Skua found at Cape Le Grand National Park near Esperance was detected on Sunday.
Previously, Australia was the only continent where the H5N1 pathogen had not been recorded. The strain is rapidly spreading across both wild bird and poultry populations, although human infections continue to be rare.
Collins acknowledged that they knew they could not remain perpetually free of avian flu, and she also reported a second suspected case: an exhausted Southern Storm Petrel was found on a beach in Esperance. However, authorities currently report no evidence of a mass die-off.
Chief Veterinarian Beth Cookson explained that the authorities had prepared extensively for this event. An Emergency Animal Disease Committee convened to discuss the necessary response. The public has been urged to avoid any contact with sick or dead birds and to report any sightings to the emergency hotline.
The primary strain circulating among wild birds globally is known as H5N1 and was first documented in China toward the end of the 1990s. Furthermore, the threat posed by avian influenza also extends to marine mammals, which are particularly susceptible to the disease.
