Adele Island is a hook shaped island off the central Kimberley coast, located around 97 km north-northwest from Cape Leveque. The island — measuring 2.9 km by 1.6 km with an area of 2.17 km² — and its surrounding sand banks sit atop a shallow-water limestone platform, surrounded by an extensive reef system. The massive tidal movements can make it hard to get close to the island to make landfall or to get off the island. The tides push through from the northwest, over underwater canyons along the continental slope and past the Lynher Banks.
