Roses-Quallup Beach (WA 168) is a 13 km long exposed, high energy southwest-facing beach located between Butty Head and Munroe Point, both prominent dune capped granite points. The entire beach and most of the backing massive dune system is contained within the Butty Head Nature Reserve. There is rough 15 km long flood-prone 4WD access via Murrays Road to Roses Beach and the western end of Quallup Beach, where a clifftop car park provides a view along the beach. The beach is 13.2 km long and commences at the base of the calcarenite cliffs, which separate it form beach WA 167. It then trends northwest as Roses and finally Quallup beach, where it curves round for the last 1 km in lee of the base of Munroe Point, which extends another 3 km to the southwest. The entire beach is exposed to high southwest waves, averaging over 2 m. These combined with the fine white beach sand to maintain a 500 m wide, double bar system. It has a rip dominated inner bar, with rips spaced every 300-400 m and more widely spaced rips cross the outer bar. The beach is backed by dunes climbing to heights of 140 m (Fig. 4.46). The dunes overlap Pleistocene dune calcarenite and extend up to 8 km inland in the west, where they are backed by Lake Mortijinup, while to the east they continue for up to 13 km inland. The massive dune field includes three episodes of dune activity. The first along much of the beach and extending up to 2 km inland, a second up to 5 km inland, and the third up to 10-12 km inland, with vegetated dunes and deflated surfaces in between. Munroe Point is a 90 m high dune-capped, granite point, which extends from Quallup Beach for 2.5 km to the southwest. Beaches WA 169-171 are located along its rocky eastern shore. All three beaches are backed by steep vegetated Pleistocene calcarenite and Holocene dunes. There is 4WD access down to beach WA 169, with a track running along the top of the ridge behind beaches WA 170 and 171. read more
