Reef health

From May to November each year, we issue regular Reef health reports. These updates are based on forecasts, water temperature heat mapping, in-water surveys, citizen science and aerial surveys.

The Reef Authority collaborates with science and management institutions to maintain a contemporary understanding of Reef health and the impacts of climate change on the World Heritage Area. 

We work with government, industry and the community to protect this great natural wonder. Here are some of the programs and projects underway to manage and protect the Great Barrier Reef.

Our Eye on the Reef monitoring and assessment program enables anyone who visits the Great Barrier Reef to contribute to its long-term protection. 

We’ve put together some information on coral bleaching here to separate facts from fiction.
