Gladstone has been an industrial port for several decades now. And there's evidence from other ports in the world that marine life can get sick if the heavy metals and mud are stirred up from the sea floor of harbours like this. So here's the question - could all the dredging that's going on here to expand the port cause disease in fish and crabs?
One one side of Port Curtis, a deeper channel is being dug for six new terminals to load giant ships with coal seam gas. The dredged mud is pumped behind a bund wall to reclaim more than 200 hectares of land for the Gladstone Ports Corporation. The rest of the mud is dumped outside the harbour, into the Coral Sea. Fish veterinarian, Dr Matt Landos believes marine life is being contaminated.
