Australia Confirms First Mass Bird Flu Mortality in Wildlife

Australian authorities confirmed the country's first mass mortality event of native seabirds due to the H5N1 avian influenza strain at Baudin Rocks on August 1.

The incident involved 49 dead and 35 sick greater crested terns, contributing to a total of 78 confirmed H5 cases across five states as of August 3, 2026.

Federal Environment Minister Murray Watt stated that national management plans are active, though the virus's spread among wild populations remains difficult to control.
