The site has historic and cultural significance for the Aboriginal community. Sand dune systems close to Sydney are rare. Whilst the coastal sand dune communities of Kurnell have been substantially degraded as a consequence of 70 years of sand removal, the surviving unvegetated Cronulla Sand Dune is intact and remains an excellent example of the former dune landscape. The Cronulla Sand Dune in the context of its setting, intactness, aesthetic qualities and social significance is held in high community esteem. The water bodies formed by sand removal surrounding the Cronulla Sand Dune have been identified by NPWS as a significant habitat for the endangered Green and Golden Bell Frog.
