Tasmania has confirmed its first detection of H5 avian influenza after a wild brown skua was found dead on the state’s north-west coast. Authorities have activated their response plans but stress there is currently no evidence of an outbreak in commercial poultry and the risk to human health remains low.
Tasmania has recorded its first confirmed case of H5 bird flu, marking a significant new development in the spread of avian influenza across Australia.
The Department of Natural Resources and Environment Tasmania confirmed on Thursday that testing had detected H5 avian influenza in a wild brown skua found dead on the state’s north-west coast.
The bird carcass was discovered after Parks and Wildlife Service officers monitoring coastal areas alerted authorities.
The positive result has triggered Tasmania’s bird flu response arrangements, with surveillance and biosecurity measures now being stepped up.
No outbreak in poultry
Tasmania’s Primary Industries and Water Minister Gavin Pearce stressed that the detection does not mean the state is experiencing a widespread outbreak.
There is currently no evidence of H5 bird flu in Tasmania’s commercial poultry industry.
Authorities have been working with poultry producers to strengthen preparedness and ensure farms have biosecurity plans ready to be activated if required.
This distinction is important.
The confirmed case involves a wild bird, not poultry raised for commercial egg or meat production.
Tasmania becomes latest state to detect H5
H5 bird flu was first confirmed in wild birds on mainland Australia in June 2026 and has since been detected in several states.
The virus has been found in wild bird populations in Western Australia, South Australia, Victoria, New South Wales and Queensland, with Tasmania now joining the list.
The spread has been linked to wild and migratory bird movements.
Australia had remained free of the globally circulating H5 strain for considerably longer than many other parts of the world, but authorities had been preparing for its eventual arrival.
Authorities monitoring wildlife
Tasmania has already been carrying out targeted surveillance for signs of the disease.
Wildlife and biosecurity officers have been monitoring beaches, coastal habitats and bird populations, particularly for unusual numbers of sick or dead animals.
The brown skua that tested positive was detected through that monitoring process.
Authorities say surveillance will now continue as they seek to establish whether further infected birds are present.
What is H5 bird flu?
H5 avian influenza is a highly pathogenic form of bird flu that can cause severe disease and high mortality among some species of birds.
Wild birds can carry the virus over long distances and potentially introduce it into new regions.
The greatest concern is that infected wild birds could come into contact with poultry farms, where the virus could spread rapidly among large numbers of birds.
Strong farm biosecurity is therefore considered one of the most important lines of defence.
Human risk remains low
Tasmanian authorities have also reassured the public that the risk to human health remains low.
Human infections with H5 bird flu are considered rare and are usually associated with close contact with infected birds or contaminated environments.
People are being advised not to touch sick or dead wild birds.
Anyone who finds unusual numbers of dead or visibly unwell birds should report them rather than attempt to handle the animals themselves.
Concern for vulnerable wildlife
The arrival of H5 is also raising concerns about native Australian wildlife.
Some bird species live in dense colonies, creating conditions in which infection can potentially spread quickly.
Seabirds are of particular concern because many travel long distances and gather in large numbers at breeding sites.
Penguin colonies are also being closely monitored.
In Victoria, authorities have announced measures aimed at protecting vulnerable little penguins as H5 detections continue to emerge.
Victoria stepping up protection
Thousands of penguins in Victoria are expected to receive vaccination as authorities try to reduce the potential impact of the virus on vulnerable colonies.
Recent detections have been reported in several parts of Victoria, including areas around Phillip Island and regional locations.
Officials have warned that stopping the virus from circulating among wild birds may not be possible.
The focus is therefore increasingly shifting towards protecting species considered particularly vulnerable.
Poultry industry on alert
For Australia’s poultry sector, the biggest challenge will be preventing the virus from entering commercial farms.
An outbreak in poultry could require large-scale containment measures and potentially the destruction of infected flocks.
That could have significant consequences for farmers, food production and supply chains.
For now, however, authorities continue to emphasise that Australia’s commercial poultry sector has not been affected by the current spread of H5 in wild birds.
No reason for panic
Tasmania’s first case is an important milestone, but officials are urging the public to remain calm.
There is no evidence of widespread disease across the state, no confirmed infection in commercial poultry and no indication of a significant threat to the general population.
The priority now is surveillance, early detection and biosecurity.
Tasmania had been preparing for the possibility of H5 reaching the island.
That possibility has now become reality.
The next challenge will be determining whether this remains an isolated detection or becomes part of a broader spread among Tasmania’s wild bird populations.
