AVIAN INFLUENZA (H5 BIRD FLU) – FREQUENTLY ASKED QUESTIONS

Last updated: 26 July 2026

What is H5N1 bird flu?

H5 bird flu (H5N1) is a highly contagious disease that can affect wild birds, farmed birds, pet birds and mammals.

The disease is caused by a strain of avian influenza virus and can spread rapidly among bird populations. It has now been detected on every continent.

The virus has also infected more than 100 mammal species globally, including seals, cats, dogs, foxes, bears and cattle and caused major wildlife mortality events, including the reported loss of more than 13,000 southern elephant seal pups on Heard and McDonald Islands.

It is considered a serious threat to wildlife and agriculture, which is why it is a nationally notifiable disease in Australia.

Has H5N1 bird flu been detected in Australia?

Yes, the first confirmed case was recorded on 20 June 2026.

As of 26 July 2026, there have been 20 confirmed cases of H5 bird flu in Australia:

• 10 cases in Western Australia
• 7 cases in South Australia
• 2 case in New South Wales
• 1 case in Queensland

Australian authorities are actively monitoring the situation and responding in line with the national response plan.

Are humans at risk of being infected from H5N1?

While there is no evidence the H5 bird flu strain spreads between people, it is still advised to avoid contact with sick or dead birds and animals.

Is there a cure for the H5N1 outbreak?

There is currently no cure for H5N1 avian influenza in wild birds or wildlife populations. Once the virus enters a wild animal population, management focuses on surveillance, biosecurity, reporting and limiting its spread rather than treating infected animals individually.

What is being done to prepare and respond to the H5N1 outbreak?

The Australian Department of Agriculture, Fisheries and Forestry is working with a range of partners, including BirdLife Australia and Wildlife Health Australia, to prepare for and respond to H5N1 outbreaks.

Why is this important for Australian wildlife?

Australia is home to many unique bird species, including migratory shorebirds and seabirds that play a critical role in healthy ecosystems.

Early detection and reporting of bird flu helps authorities respond quickly, monitor the spread of the disease and reduce risks to wildlife populations.

What is WWF-Australia doing to support the H5N1 outbreak?

• WWF-Australia is urging for a substantial increase in government funding to support efforts to respond if there are more confirmed cases, enhanced conservation measures for threatened bird species, and support for Indigenous ranger groups on the ground.
• WWF-Australia's long-term contribution is supporting Indigenous-led nature-based solutions that strengthen the resilience of Country, wildlife and communities. Working alongside Traditional Owners and Indigenous ranger groups, we support the stewardship of critical habitats, strengthen local monitoring and knowledge systems, and build the partnerships needed for coordinated responses to emerging threats such as bird flu.

How can I help?

You can play an important role by staying informed and reporting any unusual bird deaths.

If you see a sick or dead bird, please:

• AVOID: Do not touch the birds. Observe from a safe distance.
• RECORD: Take photos or videos if it is safe to do so.
• REPORT: Report the sighting to the Emergency Animal Disease Hotline on 1800 675 888.

Your report could help authorities detect and respond to outbreaks more quickly.

Where can I get more information?

For the latest updates and official guidance, follow information provided by Australian biosecurity authorities and wildlife health organisations.

If you need to report dead or sick birds, contact the Emergency Animal Disease Hotline: 1800 675 888.
