The UNESCO delegation will investigate concerns that the mining industry is damaging the Great Barrier Reef. The exploitation of oil and gas is driving industrial expansion along much of the northern Queensland coast, including plans for the world's biggest coal port near the town of Bowen.

The Australian government has imposed strict guidelines to protect marine life and ensure water quality.

But environmentalists want the authorities to suspend all new developments while an official review of the health of the Great Barrier Reef is carried out.
