A single suspected case of bird flu has triggered fears a deadly strain that has killed millions of animals worldwide has reached the Australian mainland.
Agriculture Minister Julie Collins confirmed a single migratory wild bird had been detected with a suspected case of the disease in Western Australia.
But it was too early to confirm it was the concerning H5N1 strain that has killed millions of birds around the world, the minister said, with results from further testing expected on Saturday.
Mainland Australia is the only continent yet to detect the killer strain.
"There is no evidence of any mass mortality at this time, nor is there any evidence of infection in poultry," Ms Collins said.
"If it is confirmed to be the H5 bird flu, this will be sobering, but not unexpected, given the spread globally."
