To achieve these goals they decided to reduce pollutants in the water entering the reef and to rehabilitate and conserve areas of the reef that naturally help reduce water pollutants. Stretching for 1,429 miles over an area of approximately 133,000 square miles , the Great Barrier Reef is the largest coral reef system in the world.

Coral reefs vary greatly in size and type, but all are highly sensitive to changes in the water. Thus, while non-permanent platforms could be possible in some areas, overall, permanent platforms are likely a necessity. The Reef Research Centre, a Cooperative Research Centre, has found coral 'skeleton' deposits that date back half a million years. Potential significant harms have been identified in relation to dredge spoil and the process of churning up the sea floor in the area and exposing it to air: firstly, new research shows the finer particles of dredge spoil can cloud the water and block sunlight, thereby starving sea grass and coral up to distances of 80 km away from the point of origin due to the actions of wind and currents. As many barrier reefs are long ... Great Barrier Reef. [28] According to the GBRMPA, the current, living reef structure is believed to have begun growing on the older platform about 20,000 years ago.
