Bird flu H5N1 has been confirmed in Sydney’s south and east, leading authorities to urge pet owners to protect dogs and cats. The virus was also found in the Illawarra and Shoalhaven regions, adding to the growing list of Australian hotspots. In the Northern Territory, officials have started a cull of about 5,500 feral pigs to stop the disease from moving into wildlife. The pig cull aims to protect the famous wetlands that are home to many native species and to reduce the chance of the virus jumping to other animals. Health agencies are warning that the spread could affect livestock and, in rare cases, humans, so they advise keeping pets indoors and avoiding contact with wild birds. Ongoing surveillance will track new cases and guide further actions across the affected states.

What Happened

H5N1 bird flu was found in the south and east of Sydney and in the Illawarra and Shoalhaven areas. The Northern Territory responded by planning to cull roughly 5,500 feral pigs to keep the virus from spreading further.

Why It Matters

The disease can move from wild birds to mammals, including pets, livestock and, rarely, humans. Feral pigs can carry the virus over long distances, threatening wetlands that host many native species. Protecting pets and preventing an outbreak in farms are key public‑health goals.

What Happens Next

Health officials will keep testing wildlife and domestic animals, advise pet owners on safety steps, and continue the pig cull if needed. Monitoring of the wetlands will continue to see if the virus establishes a foothold, and any new cases will trigger further control measures.
