Hydrographic Crewing Divisions

The RAN Australian Hydrographic Service has responsibility for charting more than one eighth of the world's surface, stretching as far west as Cocos Island in the Indian Ocean, east to the Solomon Islands, and from the Equator to the Antarctic.

The nautical charts developed from data gathered by the Hydrographic Service are essential for safe navigation at sea.

Around Australia, less than half of the area has been surveyed to acceptable standards, however the two Leeuwin Class ships, with multi-beam echo sounders, will greatly reduce this figure, making passage of vessels safer and further protect Australia's ocean environment.

The Leeuwin Class Hydrographic Survey ships are multi-crewed with 3 crews rotating through the two ships, HMAS Leeuwin and HMAS Melville.
