The northern shore of North Stradbroke Island faces essentially due north and runs for 13 km from low, sandy Amity Point to 25 m high Point Lookout, the north-east tip of the island. In between are four sandy beaches, the eastern three bordered by rocks and headlands, together with the growing town of Point Lookout, which now backs about 3 km of the north-eastern corner of the island.Flinders beach (1581) is an 8 km long, north-east to north facing beach, bordered by Amity Point and extensive tidal shoals in the west and the 20 m high Rocky Point in the east. Between the two points, the shoreline has built out 1 to 2 km over the past few thousand years as a series of foredune ridges and spits, backed by an extensive swamp that is drained by two small creeks, one in the centre and one just west of Rocky Point. There is vehicle access to the beach toward the western end along the Flinders Beach Road, which also leads to a camping area and car park, and in the east at Adder Rock, where there is also a beachfront caravan park. The beach has a relatively low gradient and is either barless or fronted by a narrow continuous bar, particularly toward the east. Seaward of the bar, sand moves from east to west in the form of elongate sand waves and bars, which result in a highly variable outer surf zone. During high swell a strong westerly drift runs along and off the beach.
Bombo Beach (NSW 392) is an exposed 1.2 km long east-facing beach located between Cathedral Rocks and Pheasant Point. While the beach is highly visible from the northern end it is difficult to access requiring a circuitous drive under the railway, to the car park and amenities on the northern slopes overlooking the beach, with the only other access via a walking track under the railway at the southern end. The abandoned Bombo Quarry dominates the northern headland, with a steep rise to Pheasant Point in the south. A small creek crosses the northern end and the larger Spring Creek drains out against the southern rocks. The beach receives waves averaging 1.5 m, which maintain a rip-dominated surf zone, with strong, permanent rips against each headland and 3-4 more transient beach rips in between. The rips are usually visible as you drive south and probably result in many swimmers continuing on past to safer beaches. The rips and bars however produce the beach breaks for which the beach is well known by surfers.
Point Roadknight is a narrow ridge of dune calcarenite that parallels the adjoining Urquhart Bluff Beach. The point and its reef protrude 500 m to the east and afford considerable protection to the beach. The beach is 700 m long and faces north-east. It lies between the slippery Soapy Rocks and the point. Beware of the slippery rocks which are a hazard to walk on. There is road access to the back of the beach, a large car park, a boat ramp and a yacht club.Waves reaching the beach average less than 1 m, which results in a continuous, attached bar and usually no rips.
