Hellyer Beach (T 1010) is a 2.5 km long slightly curving north-northeast-facing sandy beach, bordered by low rocky points and platforms in the west and the 200 m wide shallow mouth of Pebbly Bay and the Detention River in the east (Fig. 4.219). The beach receives waves averaging over 1 m, which maintain a 600 m wide ultradissipative beach system consisting of a 200 m wide low tide terrace and two shore-parallel subtidal bars. Waves usually break across the inner intertidal bar, only breaking on the outer bars during higher wave conditions. In addition several low reefs outcrop along the low tide beach. It is backed by a well-developed series of four to five foredune ridges with the highway running along the crest of the inner ridge, and a 500 m wide wetland behind. Most of the area between the highway and beach is a coastal reserve. The small settlement of Hellyer is located at the eastern end of the beach between the highway, beach and bay. The highway crosses the river 800 m in from the mouth and then trends southeast, not nearing the coast again till Boat Harbour 18 km to the east. read more
