When dead fish began washing up on South Australian beaches earlier this year, Dr Scott Bennett was alarmed.

Scott’s a marine ecologist at the University of Tasmania, and knew that dead fish on shore meant trouble under the surface.

On a dive in June, Scott came face-to-face with the devastating impact of the largest algal bloom Australia has ever seen.

The full impact still isn’t known – but some of Australia’s rarest and strangest animals could be wiped out entirely.
