What happened

A long-nosed fur seal has died from H5 bird flu in South Australia, marking the first confirmed case in a mammal on the Australian mainland.

Why it matters

The seal was found dead at Beachport on Wednesday on the state’s Limestone Coast.

Common ground

It marks a fresh escalation in the spread of the virus days after the South Australian premier, Peter Malinauskas, announced three mass mortality events on offshore islands involving more than 1,000 greater crested terns.

Perspective signals
