Bird Flu Confirmed on Australian Mainland
3 Aug
Summary
- H5N1 bird flu confirmed in South Australian terns and a seagull.
- Millions of birds globally have died from the H5N1 strain.
- Australia braces for wider spread, potential poultry industry impact.
The H5N1 strain of bird flu has now been established on the Australian mainland, with federal confirmation of positive tests in greater crested terns at Boudin Rocks, South Australia, and a seagull in Robe. This development signals a significant concern for wildlife conservationists and the agricultural sector.
Agriculture Minister Julie Collins stated that significant wildlife losses are now unavoidable and Australians should expect increased spread. Environment Minister Murray Watt described the current mass deaths as merely the beginning of a potentially long struggle, drawing parallels to devastating outbreaks elsewhere.
The poultry industry is on alert, having learned from past outbreaks. Biosecurity measures have been enhanced, though a 2024 incident involving a different strain led to millions of chickens being culled and egg shortages.
Experts warn the virus could spread rapidly inland, facilitated by migratory birds and affected waterways. Concerns also extend to potential impacts on scavenging mammals, with warnings issued against approaching or touching birds exhibiting symptoms like disorientation or breathing difficulties. Public health advice urges avoiding large gatherings of wild birds to minimize transmission.
