Australia's Queensland state has confirmed its first case of the H5N1 strain of highly pathogenic avian influenza (bird flu), becoming the fourth Australian state to detect the virus and prompting authorities to strengthen surveillance and biosecurity measures.

The Queensland government said the virus was identified during routine disease monitoring, with veterinary and biosecurity officials responding swiftly to contain the outbreak. Quarantine measures have been implemented at the affected location, while investigations are underway to determine the source of the infection and identify any potential links to wild birds or poultry movements.

Officials said the detection does not change Australia's food safety advice, stressing that properly cooked poultry products and eggs remain safe to eat. They also emphasized that the risk of transmission to the general public remains low.

The H5N1 virus primarily affects birds but has spread widely among wild bird populations in many parts of the world over recent years. In some countries, outbreaks have also been detected in mammals, prompting increased global monitoring by animal and public health authorities.

Queensland's confirmation means four Australian states have now reported H5N1 detections, highlighting the growing challenge of preventing the virus from spreading among domestic and wild bird populations.

Authorities have urged poultry farmers to maintain strict biosecurity practices, including limiting contact between domestic flocks and wild birds, monitoring animals for signs of illness and reporting any unusual deaths immediately to veterinary authorities.

The outbreak is expected to result in increased surveillance, movement controls and testing in surrounding areas as officials work to prevent further transmission.

Industry groups are also monitoring the situation closely, noting that bird flu outbreaks can disrupt poultry production and trade if not contained quickly. However, authorities stressed that Australia's rapid response systems are designed to minimise the impact on the poultry sector.

Public health experts said there is currently no evidence of sustained human-to-human transmission of H5N1. Most human infections recorded globally have involved close contact with infected birds or contaminated environments.

The Australian government said it is working closely with state authorities, veterinary experts and the poultry industry to contain the outbreak and protect both animal health and agricultural production.

Investigations into the Queensland case remain ongoing, with authorities expected to provide further updates as additional testing and surveillance are completed.
