Regarded as one of the greatest wreck dives in the world, the 110-meter S.S. Yongala once lay undiscovered on the ocean floor for over half a century after its untimely demise in 1911. Situated between the towns of Townsville and Ayr off the coast of Queensland, Australia, the S.S. Yongala is one of the largest and most intact historic shipwrecks that can be explored under the sea. Being the only reef formation in the region, the ship attracts and hosts a higher density of marine life than you might believe possible. An array of technicolor corals have found refuge on the ship and set the building blocks for the unbelievable self-sustaining microcosm that the ship is today. See giant trevally, marble rays, sea snakes, sea turtles, giant Queensland groupers, and schools of barracuda circle the ship as you gaze at the wonders that lie beneath the surface around the wreck. Listen for the songs of humpback whales as they make their way north through this migration corridor to the warmer waters of the Great Barrier Reef.


The S.S. Yongala encountered a cyclone on March 23, 1911, and sank with all 122 passengers on board. The exact happenings on this tragic day in Australian maritime history are unknown, though research supports that the ship was sunk suddenly as no life rafts were deployed and the steamship was still en route. After a failed 7-day search for the vessel, the ship lay on the ocean floor until 1958. It has remained mostly untouched over the years, first protected by its remote location, then formally under the Historic Shipwreck Act in 1976.
