Quinns Rocks is the name of an area of shallow reefs located 1.5 km off the coast, 30 km north of Perth. The lower waves in lee of the rocks have resulted in the progradation of a 300 m wide sandy foreland. Today this foreland and its backing dunes are occupied by the coastal settlement of Quinns Rocks and the new northern Quinns Estate. The settlement has a 2 km beachfront consisting of the Quinns Rocks Beach on the southern side of the foreland and Wanneroo Beach to the north. Both beaches are backed by a wide foreshore reserve occupied by 10 m high dunes, all backed by Ocean Drive together with a ramp for beach boat launching and a picnic area. At the southern end of the drive is a beach side caravan park, beyond which is the Mindarie Keys boat harbour and expanding residential development.
Wanneroo Beach commences on the northern side of the breakwater and continues north for 3.2 km to the next bluffs. The Quinns-Mindarie Surf Life Saving Club, founded in 1982, is located in the centre of the drive on the north side of the foreland, and just north of the post office and shops. It has a large car park adjacent to the small club house. The reserve then houses continue for another 2 km up the beach. Low swell and reflective beach conditions usually prevail, with a bar and rips occurring only during and following periods of higher waves.
Quinns Rocks-Wanneroo beaches have a relatively low hazard rating with usually low waves and few rips. However the beach can be steep, with deep water just off the beach, so care is required with young children and non-swimmers.
Waves are usually too low and the surf zone too narrow to produce rideable waves.
