Authorities on the alert for the deadly H5N1 strain of bird flu have tested dead shearwaters,also known as muttonbirds,in NSW and Victoria.
Bird flu has killed more than 30,000 South American sea lions,17,000 southern elephant seals,numerous porpoises,dolphins and otters,and more than 650,000 native birds.
A steady supply of eggs is still several months away,farmers say,as the industry scrambles to recover from a bird flu outbreak earlier this year.
A new strain of bird flu is causing a wave of deaths in animals around the world. What needs to happen for it to infect humans,and how prepared are we?
