The Corindi River, also known locally as Red Rock River, is a pristine barrier river estuary on the north coast of New South Wales, entering the Pacific Ocean at the township of Red Rock. This tranquil waterway is characterized by vast tidal flats, extensive mangrove and saltmarsh communities, and calm waters ideal for a variety of recreational activities. The estuary is surrounded by Yuraygir National Park, creating a scenic backdrop of protected coastline and headlands, including the iconic twenty-metre high Red Rock headland composed of ancient red jasper. The system offers excellent water quality, with recent monitoring grading both algae abundance and water clarity as excellent, contributing to a healthy ecosystem for fish and wildlife.
