Coral bleaching vs mortality
When the ocean get too hot, corals expel the zooxanthellae algae that lives in their tissue.
In Western Australia, the damage to coral reefs including the World Heritage-listed Ningaloo has eclipsed any previous bleaching events.
These microorganisms give corals their bright pastel colours and disease resistance.
Their absence creates the bleaching effect many Australians have become all too familiar with.
Mass coral death at Ningaloo Reef
A fresh survey of eight sites along WA's Ningaloo Reef has revealed more than 60 per cent of corals have died.
Record water temperatures caused widespread bleaching last summer.
Of the 1,600 corals counted in March [last year], only 600 were still alive come late October.

Climate category, third place: Bleached
‘An unprecedented heatwave struck the coast of Western Australia during the summer of 2024-2025. We headed out to document the worst coral bleaching event ever recorded on the Ningaloo reef. White skeletons of suffering corals swept far beyond what our eyes could see. An estimated 60-80% of our reef was bleaching before our eyes.’

Above-average ocean temperatures in the North #Pacific lead to very extensive regions where #coral #bleaching is possible.
