Tasmania reported its first H5N1 avian influenza case on August 13, 2026, after a migratory brown skua tested positive, marking the virus's presence in all six Australian states.
Federal Agriculture Minister Julie Collins announced the acquisition of 1,500 vaccine vials, while Tasmania plans to vaccinate up to 350 critically endangered orange-bellied parrots.
Authorities have intensified surveillance and biosecurity measures across the state to manage the outbreak following the initial detection of the strain in Western Australia in June.
