Australian zoos and wildlife rescues ramp up biosecurity as bird flu spreads

The highly pathogenic H5 strain of avian influenza has been confirmed on Australian soil, prompting wildlife authorities and animal attractions to strengthen biosecurity measures.

Zoos across the country are adjusting operations. Adelaide Zoo has closed its walk‑through aviaries, suspended the little‑penguin experience and halted daily free‑flight bird shows. Perth Zoo has installed extra barriers, signage and hand‑sanitiser points, added roofing over habitats of vulnerable species and is considering PPE for staff and visitors. “Our focus is always the welfare of the animals in our care,” said Phil Ainsley, chief executive of Zoos SA, noting that detailed plans are in place.

In Queensland, a sick northern giant petrel found on Noosa beach was taken to Twinnies Pelican and Seabird Rescue for testing. The twin owners, wearing PPE, said, “We have to take precautions as these poor beautiful birds have been affected in other states.” Biosecurity Queensland is handling the sample and will announce a result only if it is positive. To date there are seven confirmed cases in Western Australia, five in South Australia and one in New South Wales, with no evidence of infection in poultry or a significant human health risk.
