Blue Bay (beach WA 789) commences in lee of the boundary reef. The beach receives low ocean waves averaging less than 1 m, which surge up the steep, narrow beach. Larger waves break over the narrow, continuous bar and patches of shallow calcarenite reef, with a lefthand break running off the southern reef. The beach trends northeast of the reef for 800 m, the first 400 m relatively free of rock, the northern 400 m fronted by continuous beachrock. Halls Head road runs along the top of the backing bluffs providing good access and views along the beaches. There is a car park, toilets and access at the southern ends, with the Blue Bay Caravan Park behind the centre of the beach. The road continues round Robert Point to beach WA 790 (Fig. 4.166). Halls Head subdivision backs all three beaches. The beach terminates at low sandy Robert Point, which sits atop an intertidal calcarenite reef. Robert Point is a major inflection point in the coast and represents the northern end of the Bunbury-Mandruah ‘embayment’ and the beginning of the Mandurah-Becher Point ‘embayment’. read more
