The western side of North Stradbroke Island faces into the southern half of Moreton Bay. The sandy shore receives no ocean swell, except at the very north-western entrance. Only at the protruding Dunwich and along the north-western Amity shore are the bay waves sufficiently high to maintain low energy sandy beaches fronted by tidal flats and/or tidal channels. As the bay narrows south of Dunwich, the low energy conditions permit mangroves to dominate the shore, while between Dunwich and Amity extensive sand flats and tidal shoals extending 12 km into the bay also maintain calm conditions and a mangrove-fringed shore. In all, there are five bay beaches between Dunwich and Amity Point. Amity Point beach (1580) extends from the north side of the seawall for 2 km to the low, sandy Amity Point, which forms the northern boundary of the tidal Rainbow Channel. To the east of the point, ocean waves regularly reach the shore. Immediately north of the seawall, the narrow beach is backed by a few houses, with makeshift seawalls, then a broad, wooded reserve. The beach is usually calm, except during very high swell conditions, when low waves move around the point. However the Rainbow Channel carries strong tidal currents just off the beach, which no doubt contribute to the beach erosion. read more
