Uncontrolled access was preventing vegetation establishing to stabilise the foredune. Dune fencing has been put in to: - better manage and conserve the dunes to maintain the sanded beach area for the public, life saving services and several community clubs, - provide wider and better defined access to the beach, - protect and enhance fragile native dune grasses, - buffer the increasing severity and frequency of storm events, - reduce sand drift onto the foreshore pedestrian and bike paths. The 1.8km dune fencing cost approximately $60,000 in 2012. The fencing better balanced users access needs and successfully led to a net increase in dunal grasses of 3733m2 (31,524m2 to 35,257m2), made up of around 15 native grass species (including species of regional significance) which have been able to self seed. The sand retained by the grasses has provided a sand reserve or sand bank from erosion events to replenish the beach sand, however its effectiveness is likely to reduce against the expected inundation levels and changed climatic conditions in the future.
