Australia's first museum was opened in 1827 in Sydney with the goal of showcasing unique specimens relating to the country's fascinating natural history. Initially called the Sydney Museum or Colonial Museum, the institution was renamed the Australian Museum in 1836 and reopened in its current location on Williams Street in 1857. The small collection of curiosities has grown to more than 18 million objects of cultural or scientific significance. The museum also plays a leading role in natural and cultural research on Australia and the Pacific, and offers a rotating slate of exhibitions, events, overnight experiences for kids, and even ecology-focused trips abroad. In 2017, a new permanent collection called 200 Treasures debuted, featuring crystals, skeletons, and a Roro feather headdress from Papua New Guinea.
