The Clarence River is Australia's largest east-coast river system, a vast tidal estuary in the Northern Rivers region of New South Wales. Flowing through the Clarence Valley, it passes historic towns like Grafton and Maclean before emptying into the ocean near the coastal towns of Iluka and Yamba. This extensive waterway is characterized by a diverse range of habitats within a single ecosystem, from its upper freshwater reaches to the expansive saltwater estuary and its junction with the sea. The river provides critical breeding grounds for many fish species and is a highly significant area for both recreational and commercial fishing. The landscape is shaped by the river, dotted with beaches, and enveloped by World Heritage-listed rainforest reserves, creating a premier destination for anglers seeking a mix of inshore, estuarine, and near-coastal fishing opportunities.
