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. One Mile beach (1578) forms the northern shore of Dunwich. It is a 500 m long, low energy strip of high tide sand, including a few scattered mangroves, fronted by 1 km wide sand flats. The beach is backed by a foreshore reserve, then houses. Amity is located on the north-western tip of the island and borders the transition from bay to ocean shore. The main settlement extends along 1 km of the west facing bay shore. Unfortunately, the settlement was located too close to the shore and natural retreat of the beach has caused a 500 m long section to be replaced by a rock seawall. This seawall divides the previously sandy shore into two beaches. read more
