H5N1 Avian influenza has now been detected in Hobsons Bay (Thursday 1 October 2026). Please be vigilant and if you see sick or dead birds or wildlife, follow the guidance below.

What is it?

H5N1 is a highly contagious strain of bird flu which has affected millions of birds and thousands of mammals overseas. It presents a significant risk to species, communities and ecosystems and is a major threat to many already threatened species.  

Reporting suspected cases

If you find sick or dead wild birds or wildlife with signs of H5 bird flu:

  • AVOID contact with sick or dead wild birds or wildlife and their environment
  • RECORD the exact location and what you observed
  • REPORT, to the Department of Energy, Environment and Climate Action online here. 
  • or by calling the Emergency Animal Disease hotline 1800 675 888 in line with the guidance below.

DEECA will assess each report and decide if testing is needed.

Keeping your pets safe

While the risk of H5 bird flu in pets is low, it's best to take precautions.
If you're out walking your dog or spending time outdoors:
  • keep dogs on a lead in areas with native wildlife
  • don't allow pets to investigate or eat dead animals
  • stop cats from roaming and hunting wildlife.
These simple actions help protect pets, wildlife and curbs the spread of disease.

 

What happens when you make a report?  

Each report received is reviewed and assessed using information such as the species, number of birds affected, location and disease risk.

Not all reports will lead to an investigation, collection or testing. In areas such as the southwest coast, where the presence of H5 bird flu in crested terns is known, not every reported dead or sick crested tern will be sampled as we prioritise other species and regions where disease status is unknown.

Where further action is needed, someone may contact you for more information or arrange collection and testing. 

Community reports play an important role in helping to monitor for signs of disease.
