Point Moore residents and volunteers extended the man-made wall designed so dunes protecting the Marine Rescue headquarters can repair themselves after the ocean continues to eat around the temporary measure. More than 15 volunteers met at the Geraldton Marine Rescue headquarters on Sunday, just three months after 2000 sandbags were placed in front of the building in August. Sandbagging was used as a stop-gap measure to protect Geraldton’s volunteer marine rescue base against threats of coastal erosion, as a long-term solution remains up in air. The headquarters at Point Moore remains under threat after discovering 15m of coastline was lost after winter storms and swells battered the already fragile shore. The temporary wall made of thousands of sandbags was built in August with the help of more than 50 volunteers. Marine Rescue Geraldton commander Damien Healy said the sandbagging had worked brilliantly, but ocean swells were eating away the sides of the barrier. “We had all the bags piled up for defending and laid two layers of mesh down to protect from the side. We hope it’s buying us enough time to rebuild the dunes,” he said. “The old sandbagging has worked brilliantly, but the ocean is coming around the side of it. Because we did so much work in August, we only needed a few volunteers.” Mr Healy said he wasn’t worried about the sand dunes over summer months, but feared what was to come next winter. “I’m very concerned come winter when the swells and storms come through, If we had another cyclone Seroja then we would be really concerned,” he said. Geraldton Marine Rescue has agreed with the City of Greater Geraldton to evacuate the base if the erosion comes within 4m of the encroaching shoreline.
