The Royal Botanic Gardens in Sydney, New South Wales, is the most central of the three major botanical gardens open to the public in Sydney (the others being the Mount Annan Botanic Garden and the Mount Tomah Botanic Garden). The gardens were opened in 1816, and are managed by the same trust that manages the adjoining The Domain. The gardens are open every day of the year, and access is free.
Situated east of the Sydney Opera House, and overlooking Farm Cove, the gardens occupy 30 hectares in area, and are bordered by: the Cahill Expressway to the south and west, Art Gallery road to the east, and Sydney Harbour to the north.
The first farm on the Australian continent, at Farm Cove, was established in 1788 by Governor Phillip. Although that farm failed, the land has been in constant cultivation since that time, as ways were found to make the relatively infertile soils more productive.
The Botanic Gardens were founded on this site by Governor Macquarie in 1816 as part of the Governor's Domain. Australia's long history of collection and study of plants began with the appointment of the first Colonial Botanist, Charles Fraser, in 1817. The Botanic Gardens is thus the oldest scientific institution in Australia and, from the earliest days, has played a major role in the acclimatisation of plants from other regions.
