The exposed eastern side of Moreton Island runs for 38 km from rocky North Point down to elongate, sandy Reeders Point. In between are the rocks of the cape, then a 31 km long, slightly curving, high energy, east facing beach that extends from the south side of the cape down to the beginning of the large South Passage tidal channel. The beach then continues on for another 6 km inside the passage to Reeders Point, with increasing protection afforded by the offshore tidal shoals. The long Braydon-Sovereign beach (Fig. 1.1a) faces directly into the prevailing south-easterly waves and winds. The entire length consists of a relatively low gradient high tide beach fronted by a continuous inner bar, cut by rips every 200 to 250 m (Fig. 3.2b), then a shore parallel trough and the more continuous outer bar, lying up to 200 m off the beach. The entire beach is backed by a continuous, low, spinifex-covered foredune, then varying degrees of active sand dunes that are widest in the north, where they average 500 m, but decrease in size and extent to discrete blowouts toward the south. Beyond the active dunes are the massive older, vegetated parabolic dunes of the island. In amongst the older dunes are numerous blocked and perched lakes, particularly behind the northern 10 km of beach. read more
