Australia is launching a necessary effort to protect one of its most recognisable coastal birds from H5N1 bird flu. Wildlife teams are hand-vaccinating thousands of wild little penguins.

A suspected case of H5 bird flu has been detected in a seal at a key breeding ground, a day after Australia's first case of the virus in a mammal was revealed.

A second seal has contracted the virus in South Australia, as Phillip Island rushes to vaccinate its iconic bird population.
