Beach WA 30 commences on the southern side of the dune-capped, 10 m high, 400 m wide Point Dempster. It gently curves to the southwest and finally south for 23 km, terminating in lee of Point Malcolm. The northern section of the beach receives waves averaging over 1 m which maintain a 50 m wide bar initially cut by rips. After a 1-2 km, as wave height begins to decrease, the bar remains continuous to 5 km south of the point, beyond which the beach is reflective and barless to about 16 km south, where decreasing wave energy permits 100-200 m wide sand flats and seagrass meadows to form along the southern several kilometers of beach. At this point the beach also become crenulate alongshore, induced by shore-attached sand waves. The northern 6 km of beach is backed by some partially active dune transgression, which widens to 2 km in lee of the point. To the south 200-300 m wide vegetated foredunes, then beach ridges back the beach, which are in turn backed by 1-2 km wide, salty Lake Daringdella. The only direct access to the beach is 4 km north of Point Malcolm, near the junction of the Telegraph Line track, and near some ruins of an early homestead. The vehicle track follows the back of the beach to 1 km north of Point Malcolm where there is a small parking and picnic area. Point Malcolm is a 5-10 m high, dune-capped, gneiss headland, with large tabular slabs of gneiss thrown back on the exposed southern face. While seagrass and sand flats dominate the north side of the point, the coast to the south and west is exposed to the high southerly swell and energetic beaches and rocky coast dominate (Fig. 4.14). To the west of the point is a cuspate foreland at 2 km and the next major inflection at 8 km. In between are seven moderately exposed beaches separated by generally low bedrock points and backed by moderately active dunes. The Telegraph Track runs 2-3 km inland, with no defined access to the beaches. read more
