The current highly pathogenic avian influenza H5N1 panzootic has profound impacts on wild birds. Herein, we compiled H5N1 surveillance from Antarctica and Sub-Antarctic Islands to ascertain whether HPAI was present in this region. Observations and HPAI testing indicated no incursion of the virus during the austral summer 2022/23.
