Safe no more: off-the-charts marine heat has severely damaged Ningaloo and other pristine coral reefs
Luck seems to have run out for many Western Australian coral reefs, as an off-the-charts marine heatwave leaves a trail of bleaching and coral death.

A powerful, persuasive, emotional & evidence-based rebuttal to Wallach & Lundgren’s claims, from Professor John Woinarski. My own view, it’s essential for science to challenge dogma, but if this is not done in a robust way, using weight of evidence, it is reckless & potentially harmful. #ICCB2025

‘It was our hope spot’: scientists heartbroken as pristine coral gardens hit by Western Australia’s worst bleaching event
Usually alive with colour and fish, Ningaloo reef and the Rowley Shoals now look as though they are ‘painted white’ as temperatures rise * Get our breaking news email, free app or daily news podcast The Rowley Shoals are on many a diver’s bucket list. The three coral atolls, hundreds of kilometres off the Western Australian coastline, are teeming with pristine coral gardens that for a long time, unlike many of the world’s reefs, had escaped the ravages of global heating. “I’ve seen a fair bit of death and destruction, but Rowley Shoals was always the place that was still standing,” says Dr James Gilmour, a research scientist at the Australian Institute of Marine Science.
