A section of shoreline adjacent to Sheaffe St, Callala Bay, has been impacted on by coastal erosion at high tides and from storm events, threatening a nearby road, public reserve and multiple mature Eucalyptus botryoides trees. Shoalhaven City Council aimed to reduce risk of erosion through the rebuild of a sacrificial sand buffer via sand scraping and dune stabilisation works. The beach was scraped in early 2022, which was immediately impacted on by a significant coastal storm event. The recently nourished sand was immediately scoured, thereby fulfilling the intention of being a sacrificial buffer preventing damage to the infrastructure and natural assets further back from the shore. A secondary stage of beach scraping and foreshore stabilisation and dune rehabilitation was implemented in June 2023, with intended medium term coastal protection outcomes.
