The SS Gothenburg hits the Great Barrier Reef and sinks off the Australian east coast, killing approximately 100, including a number of high-profile civil servants and dignitaries.

SS Gothenburg was an iron-hulled sail- and steamship that was built in England in 1854 and sailed between England and Sweden until 1862. She then moved to Australia, where she operated across the Tasman Sea to and from New Zealand until 1873, when she was rebuilt. After her rebuild, she operated in the Australian coastal trade.

The Great Barrier Reef is the world's largest coral reef system, composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi). The reef is located in the Coral Sea, off the coast of Queensland, Australia, separated from the coast by a channel 160 kilometres (100 mi) wide in places and over 61 metres (200 ft) deep. The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981. CNN labelled it one of the Seven Natural Wonders of the World in 1997. Australian World Heritage places included it in its list in 2007. The Queensland National Trust named it a state icon of Queensland in 2006.
