Bathymetry
The Diamantina Deep is the zone's deepest location, located about 1 125 km West-South-West of Perth, Western Australia, at 35°S 104°E / 35°S 104°E / -35; 104. However, current etopo1-data show a maximum depth of 7299 m at 34°50′S 102°34′E / 34.83°S 102.57°E / -34.83; 102.57. At that depth this is not the deepest point in the Indian Ocean: the CIA's Physical Map of the World lists the Java Trench as such. On the western side of the Diamantina Fracture Zone at 33°30′S 101°20′E / 33.5°S 101.333°E / -33.5; 101.333 is another, larger pit, named Dordrecht Hole, with a north-south extent of 50 km. Its maximum depth is 7079 m at 33°25′S 101°29′E / 33.42°S 101.48°E / -33.42; 101.48. Dordrecht was the name of a vessel of the Dutch East India Company, which explored the Australian west coast in 1619 and discovered the Houtman Abrolhos.
The shallowest point in the area is the 1125 metre point in the Broken Ridge close to Ninety East Ridge.
