Along the coastal reaches of South Australia, a threshold has been crossed — not merely in the count of sick birds, but in what that count now means. Australia's first mass-mortality event from H5 bird flu, confirmed near Cape Jaffa in August 2026, signals that a virus once arriving in scattered incidents has begun to settle into the continent's wildlife as something more permanent. Officials are no longer speaking of containment so much as preparation, urging the public to understand that what has begun will, in all likelihood, grow.
