Under the sea, grass sways like a hula skirt around a giant clam. The underwater gardens of the Mackay Reef, off Cape Tribulation, in Far North Queensland, Australia are a natural wonderland. Global warming, the crown of thorns star fish invasion and coal mining, with its associated dredging and dumping off the coast, are the main threats to their survival.
The Great Barrier Reef risks being downgraded to a ‘World Heritage Site in danger’, thanks to the short sightedness of the current Australian Government. Despite warnings from UNESCO, a mega port development has been approved for dredging to create three shipping terminals as part of the construction of a coal port. The process will create around 3 million cubic metres of dredged seabed that will be dumped within the Great Barrier Reef marine park area.¹
