About this site
Catalina lies in Darwin Harbour, on the northern coast of the Northern Territory, Australia, an area known for its wartime wreck diving history. Darwin's waters host several sunken vessels and aircraft from the 1942 Japanese air raids, and local operators run trips out of the harbour to a number of these sites. Conditions here are shaped by the region's substantial tidal range and the associated currents, which run strong through the harbour on the change of tide. Divers have also reported Australian humpback dolphins passing through the area.
