Hyde Park, the oldest public parkland in Australia, is a 16.2 hectares (40 acres) park in the central business district of Sydney, New South Wales. Hyde Park is on the eastern side of the Sydney city centre.

Hyde Park was named after the original Hyde Park in London. The park is pock marked with drain lids, many of which lead down to Busby’s Bore, the first large-scale attempt at a water source system after the backing up of Tank Stream, the Sydney colony’s primary water source. Busby’s Bore was built between 1827 and 1837 using convict labour and fresh water from Lachlan Swamp (which later became known as Centennial Park) to the city.
