Meet the site
The RMS Quetta was an iron-hulled steamship built by William Denny and Brothers at Dumbarton in 1881 for the British India Steam Navigation Company's Queensland Royal Mail service – 115.8 m long and 3,484 tons, according to Wikipedia. On the night of 28 February 1890, bound from Brisbane to London via Torres Strait, she struck an uncharted rock in the Adolphus Channel near Albany Island. The rock split her plates from bow to engine room, and she sank in about three minutes. Of 292 people aboard, about 134 died – one of Queensland's worst maritime disasters. Survival was starkly uneven: only 19% of saloon passengers survived compared with 86% of steerage passengers, many of whom were Torres Strait Islander and South Sea Islander crew and passengers able to swim. The Quetta Memorial Church on Thursday Island commemorates the disaster. The wreck lies on its port side in about 18 m, largely intact and coral-encrusted, south of Adolphus Island. Scuba Diver Life describes rusted holds and rooms to explore and a significant gash from the sinking that creates a unique pathway through the vessel; Greatest Dive Sites gives a depth range of 10–24 m and notes parts are scattered and many artefacts have been moved to museums. The marine life is spectacular – Professional Dive Services compares it with the SS Yongala, with literally millions of fish. Divers report massive groupers, Queensland groper, manta rays, thousands of sweetlips, barracuda, cod, trout, angelfish and sharks, fed by the current that sweeps the channel. That current is the site's defining challenge. It can exceed four knots, and divers must wait for slack water – usually a short window once a day – and be ready to jump in immediately. Visibility is typically 5–15 m. The wreck is protected under the Underwater Cultural Heritage Act 2018. The Quetta suits experienced divers comfortable with strong currents and wreck diving. It is one of Australia's great historic wreck dives, and one of the hardest to time.
