Manning River (Biripi: Boolumbahtee^[2]), an open and trained mature wave dominated barrier estuary,^[5] is located in the Northern Tablelands and Mid North Coast districts of New South Wales, Australia. It is the only double delta river in the southern hemisphere in which there are two permanent entrances to the river, one at Old Bar and another at Harrington, and is famously one of only two rivers in the world to have permanent multiple entrances with the other being the Nile river in Egypt.^[6]
