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 beach (1579) lies south of the seawall and extends for up to 1.3 km, first as a low, crenulate beach backed by the caravan park, then as a low, narrow sand spit that can make up half the beach length. The spit is formed by flooding tidal currents in Rainbow Channel. There is a boat ramp at the northern end of the beach and a jetty across the beach, as well as two rock groynes. read more
