The warning signs are over: Australia now faces a devastating bird flu outbreak in wildlife
Australia is facing a significant bird flu outbreak in wildlife, with 53 confirmed cases across five states. Authorities are concerned about the potential for mass mortality and the virus spreading beyond coastal areas.
Why it matters
The spread of H5N1 in wildlife poses a serious threat to biodiversity and potentially human health if the virus continues to evolve.

At the time of writing, Australia has 53 confirmed detections in wild seabirds across five states. In South Australia there are 39 confirmed cases, including a silver gull at Robe and 19 greater crested terns found along the Limestone Coast and Seal Bay on Kangaroo Island.
South Australian authorities are also investigating 49 dead and 35 sick greater crested terns found by aerial surveillance teams at an offshore location south of Cape Jaffa.
Samples are still being tested, but if confirmed, this would represent the first mass mortality of Australian animals associated with the virus.
