Authorities have confirmed the first mass mortality event in Australian wildlife on an island off South Australia's coast and identified 386 native bird and mammal species at high to extreme risk, including marine mammals like seals and sea lions that face similar devastation seen in South America. Conservation efforts include vaccination programs in New Zealand and increased surveillance and biosecurity measures in Australia, with officials warning this outbreak represents a major threat to already vulnerable species.

What people are saying verbatim
“That sort of impact hasn't been seen with bird flu before in these species, and they're highly vulnerable as it is. There's a number of other threats that these species face, so to have a serious disease on top of all of that is a major conservation concern.”
Simon Gorta, UNSW seabird ecologist · ABC News & Headlines – Australian Broadcasting Corporation · Aug 8
“One of the sub-Antarctic islands that Australia owns, Heard Island, we have seen a mass mortality of baby seals there. We'll do everything we can to try to keep those species at a population level that they're still going to be around forever, but it's going to have very serious impacts.”
Murray Watt, Environment Minister · ABC News & Headlines – Australian Broadcasting Corporation · Aug 8
“This is certainly a disease of global importance and every citizen can play their role. Australia and New Zealand are the last region in the world to be impacted by this disease. It's really important that if anybody does see sick or dead birds, that they report it to the emergency animal disease hotline.”
Campbell-Ward, University of Sydney Associate Professor · ABC News & Headlines – Australian Broadcasting Corporation · Aug 8
“These positive cases are not unexpected. We have been preparing for a situation like this, and we remain well-equipped to respond to manage further impacts.”
