Boats can be anchored anywhere within the Rottnest Island Marine Reserve, providing the vessel is not within 50 m of a mooring or as specified by signage.  Anchors cannot be dropped in sea grass or on a reef. Popular anchorage areas include Thomson Bay (south of the Army Groyne), Longreach Bay, Parker Point and Stark Bay. More information on anchoring is available on the Rottnest Island Authority website.
