Australia's seabirds face mass H5N1 deaths, modelling warns

H5N1 bird flu lineage 2.3.4.4b killed tens of thousands of seabirds across Europe from 2022 onwards. Modelling suggests Australia's wild bird populations face similar or worse mortality events, with risk of species loss among vulnerable flocks. Sandwich terns and other seabirds that breed in colonies are particularly exposed to rapid viral spread. The piece draws on European outbreak data to forecast Australian impacts, though specific modelling methodology and affected species aren't detailed in the summary provided. This matters because Australia's seabird populations – already under pressure from fishing, habitat loss, and climate shifts – lack the disease surveillance and response infrastructure Europe deployed. The gap between prediction and preparedness is the real story. Australia's environmental agencies have been notified, but funding for monitoring wild bird populations remains constrained. Whether governments act before mortalities spike, not after, will determine whether this becomes a managed crisis or an uncontrolled collapse of already-declining populations.

When bird flu hit the UK, suffering seabirds died in their thousands. Australia’s wild flocks will soon do the same
