The 3 km long Greenhills section of the beach (NSW 334a) initially faces due south exposing it to the strong southerly winds, but not to the waves which are abated 2 km offshore by the Merries Reef. As a result the northern 1.5 km of the beach receives waves averaging 0.5 m which maintain a steep reflective beach in the east grading slowly south to an attached bar. It is backed initially by vegetated sand dunes then by the degraded Kurnell dunes. As the beach swings more to the southeast the waves start increasing in height along the southern 1 km and rips begin to cross the bar every 150-200 m. The beach can only be reached on foot from the Boat Harbour or the southern car parks. read more
