The gentoo penguin has become the first bird to test positive for the H5N1 bird flu on an Australian territory, with samples confirming the virus has spread on a sub-Antarctic island.<\/p>\n
The deadly and contagious strain of bird flu, which has already killed millions of seabirds, wild birds and poultry overseas, was confirmed in southern elephant seals on Heard Island in November 2025.<\/p>\n
Fur seals and gentoo penguins have now tested positive for the virus, according to the federal government, after further samples were collected by Australian Antarctic Program scientists on a second voyage to Heard Island.<\/p>\n
The island is an Australian territory located about 4,000km south-west of Perth, and 1,700km north of Antarctica.<\/p>\n

Prof Hugh Possingham, the vice-president of BirdLife Australia, said the spread of the virus to other species was \u201ca very concerning development\u201d.<\/p>\n
\u201cThe gentoo penguins of Heard Island are now the first birds in an Australian territory to test positive for this virus that has devastated wildlife around the world,\u201d Possingham said. \u201cThey will certainly not be the last.\u201d<\/p>\n

In the next year, it spread to Marion Island and the French Kerguelen and Crozet sub-Antarctic islands, located about 500km from Heard and McDonald islands.<\/p>\n Dr Michelle Wille, an expert in avian influenza viruses at the University of Melbourne, described the disease as \u201ccatastrophic for wildlife\u201d and said H5N1 had already spread thousands of kilometres over the ocean.<\/p>\n She said it was \u201cconceivable that the virus could theoretically spread from where it is now, into Australian [and] New Zealand sub-Antarctic islands like Macquarie Island. And from there it\u2019s not very far to get to Australia itself.<\/p>\n \u201cWe are at risk of this virus arriving to Australia, either from this potential southern route, or from a northern route,\u201d she said, which made surveillance and preparedness extremely important.<\/p>\n","protected":false},"excerpt":{"rendered":" The gentoo penguin has become the first bird to test positive for the H5N1 bird flu on an Australian territory, with samples confirming the virus has spread on a sub-Antarctic island.
