The Manning River is a unique and biologically rich estuary system on the Mid North Coast of New South Wales. It is renowned as the only double delta river in the southern hemisphere, featuring two permanent entrances to the Tasman Sea: Harrington Inlet in the north and Farquhar Inlet in the south. This creates a vast, complex network of channels, islands, and tidal flats that define the fishing experience. The river flows 261 kilometers from its headwaters in the Barrington Tops National Park, descending 1,500 meters through the Manning Valley, and is fed by a large catchment covering over 8,000 square kilometers. Notably, it is one of the few major rivers in NSW not dammed for water supply, though water is pumped to the offsite Bootawa Dam. The estuary supports a diverse aquatic ecosystem and is a premier destination for recreational anglers targeting a variety of saltwater and estuarine species.
