This project was implemented to rehabilitate the dune in front of the Shoalhaven Heads Surf Life Saving Club and to protect the Club building and Council assets from storm damage and erosion. Approximately 4,000m3 of sand was scraped adjacent to three beach access tracks to reduce the foredune slope. This was followed by the revegetation of 3000 tube stock plants secured with jute matting, and installation of fencing to prevent pedestrian access to the dunes during the recovery phase. The dune stabilisation works have been monitored and maintained by the Council on an ongoing basis since implementation.
