Wooli beach has a long history of coastal instability, and the local village is at significant risk from storm erosion and long term coastline recession. A trial beach renourishment was undertaken in 2019 at a cost of $80,000, complemented by $20,000 in dune revegetation. The trial was funded by Clarence Valley Council, NSW Government and Coastal Communities Protect Alliance - Wooli (CCPA). Due to the trial's success, the most recent Beach Management Strategy finalised in 2021 recommends continuing to focus on nature-based solutions, including beach scraping, mechanical dune reshaping, dune fencing and revegetation. Similar costs to the 2019 trial are expected for future operations.
