Avian influenza (bird flu)

What is bird flu?

Bird flu is a viral disease of birds and is found across the globe. It mainly affects birds, but can also affect other animals, and, on rare occasions, humans.

H5 bird flu, specifically high pathogenicity avian influenza H5N1 clade 2.3.4.4b is a serious and highly contagious strain that has moved quickly around the world. Australia is currently the only continent free from this strain of H5 bird flu.

Wild, farmed and pet birds can catch bird flu. Overseas, other animals have become infected by this strain of H5 bird flu. These were mainly marine mammals and bird-eating scavengers noting cases were detected in other mammals including dairy cattle and cats.

A few mild human infections of the H5 bird flu strain of concern have been reported overseas. Most infected people had close contact with infected animals and contaminated environments. The likelihood of humans becoming infected is very low as current strains of H5 bird flu circulating overseas do not appear to transmit easily to or between humans.

What we’re doing

While bird flu preparedness activities have been a national focus for many years, H5 bird flu has spread quickly across the world through the movement of wild birds.

We are preparing for a possible outbreak of H5 bird flu in Australia and working collaboratively with state and territory governments, industries and the non-government sector to enhance preparedness and national response capabilities.

Overseas outbreaks show that H5 bird flu would have significant impacts on our wildlife and agriculture industry, especially poultry, and communities if it reaches Australia.

Government actions are focused on preparing for an outbreak and supporting biodiversity, the industries, other sectors and communities that would be affected.

Funding our preparedness

In recognition of the H5 bird flu threat, the Australian Government is investing more than $100 million into enhancing national preparedness and response capability.

On 14 October 2024, $95 million in funding was announced, in addition to the $6.9 million announced in July 2024.

This funding will strengthen surveillance, preparedness and response capability and mitigate the impacts of a potential H5 bird flu outbreak on Australian agriculture, environment and human health.

Through this significant investment, the Australian Government is committing:

$37 million over 2 years to protect Australian agriculture by enhancing national coordination of response arrangement and communications, strengthening surveillance and boosting biosecurity capacity and capability across the production sector and environmental biosecurity.
$35.9 million over 2 years to boost and accelerate H5 bird flu preparedness planning and protective action by using the best data available to target actions for our most at-risk species and important natural places.
$22.1 million over 2 years to manufacture and store pandemic influenza vaccines that will better prepare the Australian Government to respond quickly to a potential influenza pandemic.

Report sick birds

If you find multiple dead birds or other animals, you should not touch them. Instead, take photos or a video, record your location and report it to the Emergency Animal Disease Hotline on 1800 675 888.

What you can do to help

You can help protect our wild birds and poultry industry against bird flu.

Be safe when entering wildlife areas and keep your distance if you see sick or dead birds.
Always wash your hands with soap before and after handling birds.
Commercial producers and those working with poultry need to use effective on-farm biosecurity and hygiene measures to protect your birds from disease.
People with pet birds or back yard chickens should take steps to protect their birds. Including:
- not letting wild birds mingle with your birds or access feed and water containers
- keeping aviaries and equipment clean.
Wildlife carers should use hygiene measures and personal protection equipment when handling sick or injured birds or other animals.

Avian influenza and your backyard

Avian influenza, or bird flu, is a disease carried by wild birds that can cause severe disease in poultry.

There are many strains of the virus, including the H5 strain that’s caused mass poultry deaths overseas.

Australia does not have this strain.

Avian influenza can be carried by wild birds such as ducks, geese, and swans.

If wild birds mix with our backyard poultry and pet birds, the virus can spread to them.

If you own or work with any type of poultry or birds, look for health changes in your birds.

The signs of avian influenza are similar to other bird diseases, so always check with your vet if you notice something unusual.

Look out for:

single or several birds suddenly dying
diarrhoea
birds eating or drinking less
unusual reduction in egg production
birds sneezing or looking unwell.

There are simple things you can do to help protect your birds.

Don’t feed wild birds or encourage them to mix with your poultry or pet birds.

Use netting to prevent contact between domestic and wild birds.

Clean your birds’ housing and equipment regularly and don’t share it with other bird owners.

If you bring in new birds, keep them separate and monitor them for at least 30 days before introducing them to your existing flock.

If your poultry are free range, monitor them daily for signs of disease.

Be ready to house your birds separately if they show signs of illness.

Avian influenza does not easily spread to people, and it’s a low risk to the public, but it’s still important to maintain good hygiene around poultry and pet birds.

Avoid touching sick or dead birds, or if you need to touch them, wear gloves and wash your hands afterwards.

Always wash your hands after handling birds, eggs and equipment.

Clothes and shoes should be washed after visiting a bird show, aviary, or chicken run.

If you see sick or dead birds, contact your vet or the Emergency Animal Disease Hotline on 1800 675 888.

What to expect if H5 bird flu comes to Australia

Australia has well-established national response arrangements in place to respond to emergency animal diseases, including bird flu.

If Australia experiences an outbreak of H5 bird flu, there will be a rapid and coordinated national response led by the Department of Agriculture, Fisheries and Forestry (DAFF), with state and territory governments leading response activities within their borders.

Australian Government departments, state and territory governments, sector partners, communities and businesses will work together to manage an outbreak and provide support to affected industries. Early detection and working together is important.

DAFF will also manage international reporting obligations and work with relevant trading partners to minimise trade disruptions in affected commodities where possible.
