Bird Flu Deaths Spread to Second State: What It Means 2026

Bird flu deaths have been detected in a second Australian state, with authorities warning this is the beginning of a long and difficult journey. The H5 strain has now caused mass mortality events in South Australia and suspected cases in Victoria, raising urgent concerns for wildlife and public health.

What Happened: Confirmed and Suspected Outbreaks

The CSIRO confirmed Australia’s first mass mortality event at Baudin Rocks, off South Australia’s coast, where about 50 dead and 30 sick birds were found. Samples from greater crested terns and a silver gull tested positive for the deadly H5 bird flu.

Hours later, Victorian authorities reported a cluster of dead and sick greater crested terns in the Glenelg River estuary and near Lawrence Rocks. If confirmed, this would mark the second mortality event in Australia, signaling rapid spread.

Government Response and Warnings

Environment Minister Murray Watt stated, “This is the beginning of what is likely to be a long, difficult journey.” He emphasized that wild birds cannot be stopped, and more mass mortality events are expected. The government is focusing on building resilience in native bird and mammal populations.

Why This Matters for Australia

This H5 strain has devastated wildlife globally, and its arrival in Australia is a major concern. The disease can spread rapidly among wild birds, and while the risk to humans remains low, monitoring is essential.

• First confirmed mass mortality event in Australia
• Suspected second event in Victoria
• Wild bird populations at high risk
• Government warns of more outbreaks
• Resilience building is key

What Can Be Done?

Authorities are conducting aerial and ground surveillance, but they admit they cannot stop wild birds from migrating. The focus is on supporting affected populations and preventing further spread where possible.

Potential Impact on Poultry and Humans

While the current cases are in wild birds, the poultry industry is on high alert. Outbreaks can lead to culls and trade restrictions. Human infection is rare but possible, so public health agencies are monitoring closely.
