Situated immediately southeast of the Sydney Opera House and curved around Farm Cove, the gardens occupy 30 hectares and are bordered by the Cahill Expressway to the south and west, Art Gallery Road to the east, and Sydney Harbour to the north. Royal Botanic Garden Sydney is divided into four major precincts called the Lower Gardens, the Middle Gardens, the Palace Gardens and the Bennelong precinct. Within the four major precincts are many smaller gardens and features as well as large amounts of lightly wooded lawn areas.
