The Rowley Shoals is a group of three atoll-like coral reefs south of the Timor Sea, about 260 km west of Broome on the northwestern Australian coast, centered on (17°20′S119°20′E), on the edge of one of the widest continental shelves in the world. Each atoll covers an area of around 80 to 90 km² within the rim of the reef, including the lagoons, while the land areas are negligible. They belong to Western Australia. They all rise steeply from the surrounding ocean floor.
