Switzerland: World heritage experts have decided not to officially list the Great Barrier Reef as being "in danger", but warned Australia it still has more to do to stop continuing damage to this natural wonder.

UNESCO's world heritage body, based in Paris, commissioned an expert report on the threats to the reef, including climate change, pollution run-off from the mainland and continuing coastal development.

These problems were made worse by major storms and floods, increasing concern for the survival of the reef and its precious plant and animal ecosystems.
