Comerong Island beach (NSW 401) is backed by the two channels of the Shoalhaven River and fronted by the ocean beach. When the northern river mouth closes every few years the island becomes temporarily part of Seven Mile Beach. The island extends for 4.7 km southeast from the river mouth and its extensive shoals to the northern entrance wall at Crookhaven Heads, the permanent mouth of the Shoalhaven River. It can only be accessed by a small car ferry via Nowra, or by boat, or on foot when the mouth is closed. A road leads to the back of the northern end of the beach, then down to the southern end, with a picnic area at both spots, and foot or 4WD access to the beach in between. While the rich floodplains at the rear of the island are given over to farming, the 1.5 km wide sandy barrier is part of Comerong Island Nature Reserve and covered in dense native woodlands and forests. Wave energy remains high along most of the beach, decreasing only close to Crookhaven Heads, which provides protection from east and southeast waves. Like Seven Mile a double bar system operates along most of the beach with an attached inner bar cut by periodic rips.
Beach Length: 5.5km
