Damage to parts of the Great Barrier Reef has worsened, leading authorities to raise the alert to the second-highest level, indicating severe local coral bleaching.
The bleaching is worst in the most pristine and remote parts of the reef north of Cairns, according to Terry Hughes, convenor of the National Coral Taskforce. Its the jewel in the crown of the Great Barrier Reef and its now getting a quite a serious impact from this bleaching event, he said. The northern reefs are bleaching quite badly now.
Hughes said it appeared there was some coral death occurring in northern reefs.
Russell Reichelt, the chairman of the Great Barrier Reef Marine Park Authority said the area around Lizard Island, 250km north of Cairns, and sites further north, had fared the worst.
