Summary These floodplains have supported more than 1% of the world population of Pied Heron, Brolga and Great Knot. The large numbers of shorebirds recorded at Boucaut Bay include more than 1% of the world population of Great Knot and Pied Oystercatcher.
Site description The boundary follows the coastal floodplains of the Cadell and Blyth rivers, and the adjacent length of Boucaut Bay. This IBA is situated between the Maningrida community to the west and the Milingimbi community to the east. The seasonal flooding comes from flows down the Blyth and Cadell Rivers and various creeks. Most of the floodplain is more than 1 m deep in wetter years.
