NSW has found bird flu (H5N1) in a dead seabird at Hawks Nest, north of Newcastle. This is the first confirmed case in the state. The Guardian and ABC News first reported the suspected case on 3 July, with official confirmation coming through tests on 4 July.

The bird was a giant petrel, a large seabird that migrates across the southern oceans. It travels long distances and regularly mixes with other seabird colonies, some of which have already been hit by bird flu outbreaks (particularly in South America). Finding one dead on an Australian beach is not unusual. Finding one with bird flu is.

The strain found is called H5N1 clade 2.3.4.4b. This is the same variant that has killed thousands of wild birds and some farm birds in North America, Europe, and South America since 2021. Now it is in Australia — brought here by a migrating bird, which is how disease experts always said it would arrive.

The NSW Department of Primary Industries is now running the response. They will set up restrictions on moving animals in the area, check nearby farms, and watch for more dead wild birds.

Should you be worried about chicken farms getting it? Not immediately. The bird was found at sea, far from where chickens live. There is a bit of a buffer there. But it is not time to relax completely — bird flu can spread between different wild bird species, so farms need to be ready.

Australia has spent years being known as bird-flu-free, which helps us trade with other countries. Now that we have found it here, we have to tell our trading partners. The virus must be reported, even though it has not hit any farms yet.

What happens next depends on what the virus does in the coming weeks. Do more wild birds catch it? Does it reach a farm? Does it stay coastal? The answer will depend on how well the response team does its job and how quickly they share what they find.

Chicken and poultry farmers should check their plans for keeping wild birds out of sheds and equipment. Not because an outbreak on a farm is certain or even likely, but because bird flu is now in wild birds off the NSW coast. That changes what farmers need to be ready for.
