For information on the HPAI H7 outbreaks in poultry in Victoria, NSW and the ACT, see HPAI H7 in poultry, Vic, NSW and ACT - May & June 2024.

High pathogenicity avian influenza (HPAI) H5N1 clade 2.3.4.4b has caused ongoing outbreaks of disease in wild birds, from 2021, throughout much of North and South America, Europe, Asia and Africa, and into Antarctica and its islands. Mortalities have been observed in a wide range of species, seen as individual bird deaths and have included mass mortalities. The emergence of the 2.3.4.4b strain overseas means an increased risk to Australia, due to the increase in the likelihood of entry into Australia via wild bird movements and anticipated increased consequences if it were to enter. 

Avian influenza is a nationally notifiable disease which means if you suspect an animal is showing signs of the disease, you must report it. You can do this by calling the national Emergency Animal Disease Hotline on 1800 675 888.

Note: All Australian jusrisdictions also require that all avian influenza virus detections are reported to the relevant Chief Veterinary Officer (CVO).
