H5N1 (Bird flu) in Australia

The deadly strain of bird flu, H5N1, arrived in Australia last week and threatens a list of 100 native animal species, including birds, land and sea mammals.
Two birds, the brown skua and the giant petrel flew from the sub-Antarctic region to southwest Western Australia, have been confirmed to be infected with the deadly virus.
Until last week, when the skua was found on a remote beach near Esperance, Australia was the only continent free of the deadly virus.

A giant petrel, found several kilometres away, also tested positive for the H5 strain.
Brown skuas and giant petrels are a common sight offshore in southern Australian waters in the winter months, but they will rarely risk venturing on to land.
So when two of these birds were discovered sick on beaches a few kilometres apart it was a sign something might be wrong.
Both birds have since died.

Australia’s unique wildlife, which has evolved in isolation for millions of years, could be particularly vulnerable to H5N1.The list of at-risk animals includes: bird-eating raptors, including white-bellied sea eagles, powerful owls and wedge-tailed eagles; black swans with no defences to the virus; Australian sea lions; rare parrots, including the tiny populations of orange-bellied and swift parrots; and Tasmanian devils as they eat carrion.The risk of an outbreak in farmed birds is also high, with potentially devastating consequences. Australia’s largest chicken meat producer announced on it had locked down access to all its farms in Western Australia, even though they are all north of Perth and more than 700 kilometres from where the infected birds were found.Experts had warned it was inevitable for the virus to make its way to Australia via migratory birds.

Now that it has come from the sub-Antarctic region, governments and experts say a wild outbreak is likely.However the Agriculture Minister who is responsible for biosecurity, and the Environment Minister said that only two positive cases had been identified and there was no evidence of widespread fatalities to indicate an outbreak in Australia.The Australian government committed $113 million to preparations to deal with an H5N1 incursion, with an emphasis on planning to swiftly identify an outbreak and responding to limit its spread. This includes teams to swiftly remove carcasses of infected animals to prevent further spread and stopping farmed poultry from mixing with wild birds.
