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′S 119°20′E / 17.333°S 119.333°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. To the northeast lie the Scott and Seringapatam Reefs which are located on the same undersea platform.
