H5N1 avian flu is spreading in Australian bird populations following widespread wildlife fatalities recorded across affected areas. A little penguin on King Island has tested positive for the contagion. Suspected cases of the infection have also emerged at a South Australian visitor location.
Mass vaccination of little penguins has started in response to the spread. Authorities are investigating what happens next when hundreds of animals succumb to bird flu during an unfolding crisis. Teams are striving to manage the situation and safeguard local wildlife.
