Northern NSW's Major Rivers: Clarence, Tweed, Richmond, Manning, Bellinger

Northern New South Wales (Australia) drains through five principal river systems—each with distinct character, ecology, and human history:

1. Clarence River — NSW's largest by discharge (170 m³/s avg); 400 km; Grafton; "Big River" to Bundjalung/Gumbaynggir peoples; bass, cod, prawn fisheries.
2. Tweed River — Border with QLD; volcanic origin (Tweed Caldera); 80 km; tourism, agriculture, Tweed Heads/Coolangatta urbanization.
3. Richmond River — 170 km; Ballina; historic cedar/red gold logging; sugar cane; floodplain drainage issues; cultural significance to Bundjalung.
4. Manning River — 261 km; Taree; double delta (Harrington + Old Bar); unique twin-mouth; oyster industry; Manning River helmeted turtle (endemic).
5. Bellinger River — 110 km; Bellingen; pristine upper catchment; Bellinger River snapping turtle (critically endangered); dairy, tourism.

Shared Challenges

• Flood management (2022 catastrophic floods).
• Riparian degradation, bank erosion.
• Water extraction vs. environmental flows.
• Climate change: intensified rainfall, sea-level rise.

These rivers define the "Northern Rivers" region—culturally, economically, ecologically distinct from Sydney/Canberra orbits.
