![]() Cairns 25 km, Townsville 70 km, Abbot Point 60 km, Hay Point 110 km, Gladstone 60 km. No significant ports are in the northern part of the GBR. ![]() Similar length coastlines in other parts of the world, such as in Asia and Europe, may serve a hundred or even a thousand times that number. The shipping serves a very small population of around 700 000 people over the 2 000 km length of the reef. But Hay Point is one of the largest coal export ports in the world.Īlthough there has been a rapid growth in coal exports during the last few decades, the shipping traffic in the GBR is sparse in contrast to more populated regions in Asia, Europe and the Americas. Many ports are little more than a single wharf that accepts a few ships per month. ![]() In addition, a small number of cruise ships bound for the GBR and the islands of the Coral Sea and South Pacific also use the ports. General cargo and fuel for much of north-east Australia also comes through these ports. ![]() The Great Barrier Reef ports and dredgingĪlong the 2 000 km long coast adjoining the Great Barrier Reef (GBR) there are a dozen or so ports that export mostly minerals and agricultural produce such as coal, copper, zinc, lead, silica, beef and sugar. One of the conclusions (see page one) is that dredging moves a very small amount of sediment compared with natural influences such as resuspension by the south easterly trade winds and cyclones. This document (14 MByte ) Sedimentary Geoscience of GBR-Larcombe-Ridd-Final(151202) gives details of the natural sediment movements on the GBR. Dredging is often claimed to be killing the GBR. ![]()
