The Domain is a heritage-listed 34-hectare (84-acre) area of open space located on the eastern fringe of the Sydney central business district, in the City of Sydney local government area of New South Wales, Australia. Separating the central business district from Woolloomooloo, The Domain adjoins the Royal Botanic Gardens and is managed by the Royal Botanic Gardens Trust, a division of the NSW Office of Environment and Heritage, an agency of the Government of New South Wales. The Domain is used as a venue for outdoor concerts, open-air events, large political gatherings and rallies, as well as being used daily by the people of Sydney for exercise and relaxation. Along with the Royal Botanic Gardens, The Domain was added to the New South Wales State Heritage Register on 2 April 1999.
