The Gold Coast’s biggest offshore dredge begins

The biggest offshore dredging program in the Gold Coast’s history has begun.

A 111-metre dredge vessel from Denmark will spend the next 16 weeks replenishing three million cubic metres of sand onto the city’s coast between Palm Beach and Main Beach – at a cost of $13.9 million.

Mayor Tom Tate said the project would increase the volume of sand on local beaches, above and below the waterline, to make them more resilient against coastal erosion.

He said sand will be placed in patterns to replicate natural rhythmic sand bar formations known to promote good quality surfing conditions, and added that research by City of Gold Coast officers had driven how the dredging process would progress.

“Thanks to extensive research and improved technology including the study of coastal data from wave buoys, beach surveys, camera monitoring and computer modelling, we have ample data to know exactly where to place the sand,” he said.

The sand placement will have two benefits: Sand in the wave-breaking zone will have an immediate effect on beach widening; meanwhile, sand placed further offshore in deeper areas will move more slowly, increasing the volume of sand along the beach.
