🔥 Trending Bird Flu Outbreak Spreads in Australia: What You Need to Know

Bird flu (avian influenza), specifically the highly pathogenic H5 strain, has been detected in Australia, marking a significant development as this strain has been circulating globally ¹³⁶. This is the first time the H5N1 strain, which has caused mass mortalities in poultry, wild birds, and some mammals overseas, has been confirmed in Australia ⁶¹⁰.

Current Situation and Detections

As of July 31, 2026, Australia has 33 confirmed detections of H5 bird flu in wild seabirds across multiple states ¹.

• Western Australia (WA): 10 detections ¹
• South Australia (SA): 19 detections ¹
• New South Wales (NSW): 2 detections ¹
• Queensland (QLD): 1 detection ¹
• Victoria (VIC): 1 detection ¹

The detection of H5 bird flu in Victoria was confirmed on July 30, 2026, and authorities have noted that local transmission among South Australian birds signals a "shift in the situation" ³. Queensland has activated emergency arrangements in response to the detections ⁴. The Consultative Committee on Emergency Animal Diseases (CCEAD) has met to discuss the situation and appropriate response activities following additional suspect detections ⁵.

Types of Bird Flu in Australia

Historically, Australia has experienced several outbreaks of highly pathogenic avian influenza (HPAI), mostly involving H7 strains, which were successfully contained and eradicated ¹⁰. However, the current H5 bird flu differs from these previous strains and has been impacting all parts of the world ⁶.

In June 2026, Australia confirmed the presence of H5N1 bird flu, distinguishing it from earlier outbreaks ¹⁰. The current detections are of the serious H5 strain that has been circulating globally ¹.

Impact and Concerns

The H5 bird flu strain is highly contagious and has caused significant mortalities in poultry and wild bird populations internationally ⁴⁶. Its presence in Australia raises concerns for wildlife, as it has led to mass deaths in other parts of the world ³⁶. While the current detections are primarily in wild seabirds, authorities are closely monitoring the situation.

Reporting Sick or Dead Birds

The public is advised to avoid contact with sick or dead birds or other animals ⁸⁹. If a group of sick or dead wildlife is observed, individuals should:

• Avoid contact and maintain distance ⁸.
• Record the date, time, and location, and take photos ⁸⁹.
• Report it to the Emergency Animal Disease Hotline on 1800 675 888 ⁸⁹.
