Australia whales: ‘Unbelievable’ super-group caught on film

When a drone pilot captured footage of an enormous group of whales off the New South Wales coast last year, it sent scientists into a frenzy.

A pod of that size - known as a super-group - and the "bubble-net" feeding behaviour they were displaying had never been documented off Australia before.

A research paper has now confirmed both extraordinary events.
