HMAS Diamantina

HMAS Diamantina is a River-class frigate displayed at the Queensland Maritime Museum, measuring approximately 92 meters in length. The vessel features two triple expansion engines that generated about 5,500 horsepower to drive twin screws while serving in active duty.

The frigate served at the end of World War II, transporting senior officers to various Japanese surrender ceremonies across the Pacific. After the war, the vessel was repurposed for oceanographic missions that contributed to understanding the depths of the Indian Ocean.

The ship displays how the Royal Australian Navy operated in the post-war years and what daily tasks sailors performed aboard. Visitors can see this firsthand by moving through different areas and observing the equipment and spaces used for life and work at sea.

Visitors can explore multiple decks including the bridge, engine room, and crew quarters to understand how a warship functioned internally. Comfortable shoes are recommended as navigation involves climbing narrow stairs and moving through low passageways typical of naval vessels.

During a scientific expedition in the 1960s, the vessel discovered the deepest point of the Indian Ocean while conducting research missions. This location was subsequently named Diamantina Deep in honor of the ship's contribution to oceanographic knowledge.
