The Gold Coast Broadwater, also known as Southport Broadwater, Gold Coast Harbour and The Broadwater, is a large shallow estuary of water located in the Gold Coast district of South East Queensland, Australia. The estuary reaches from the locality of Southport in the south, to the southern section of the UNESCO World Heritage Listed Moreton Bay in the north. Separated via the Seaway from the Coral Sea by a thin strip of land called Stradbroke Island, the original body of water was a lagoon created from water deposited from the Nerang River. Part of the Broadwater is contained within the Moreton Bay Marine Park.
