Beach K 83 extends 11.7 km north of Cape Borda to the lee of the beachrock reefs of Packer Island (Fig. 4.16). The beach faces generally west-northwest and consists of a continuous sand beach, with scattered sandstone reefs extending over 1 km seaward and 1.5 km north of Cape Borda, with wide sand flats to their lee. Once clear of the rocks is a 7 km long ultradissipative beach, which then grades into 1 km wide tidal sand flats up to the mouth of Gilbut Creek in lee of the southern beachrock tip of the island. The beach is backed by an extensive 1,700 ha barrier dune system, which in the centre is 2.5 km wide. The entire dune system has an outer 1-2 km active zone, backed by an inner vegetated transgressive sand ridge, which reaches a maximum height of 38 km toward the south. The dunes are backed by wooded coastal plain, except adjacent to Gilbut Creek, where mangroves back the northern 2 km. read more
