SS Yongala Shipwreck Dive Site – Great Barrier Reef

Site Overview

The SS Yongala is consistently rated as one of the world's best wreck dives and arguably the single best dive site on the entire Great Barrier Reef. This 110-meter steel passenger steamer sank during a tragic cyclone in 1911 and now rests remarkably intact on a flat sandy bottom at a depth of 14 to 28 meters. Because it is the only major structure for miles in an otherwise featureless sandy landscape, the wreck has become an incredible magnet for marine life of all sizes. It functions as a massive artificial reef, encrusted with a dense layer of hard and soft corals, sponges, and gorgonians. Divers can expect to see resident Queensland groupers the size of small cars, swirling schools of giant trevally, patrolling eagle rays, and dozens of olive sea snakes. The sheer biomass at this site is overwhelming, often making it difficult to see the wreck itself through the thick clouds of baitfish and predators. It is a protected historic site, and penetration is strictly prohibited to preserve both the structure and the diverse ecosystem that calls it home. For many divers, the Yongala represents the pinnacle of wreck diving, combining historic intrigue with world-class biological diversity in a way few other sites can match.
