Collaroy

Sand Dunes: The sand dunes at Collaroy were almost non-existent. This is because Collaroy beach is protected from large swell by Long Reef headland. The sand dunes at Narrabeen are artifical to help prevent beach erosion from large swell. Collaroy does not have this problem so has no real need for artificial sand dunes. The local council has seen no necessity to create aritificial sand dunes.
