The Tweed River catchment is highly disturbed. It supports a broad range of agricultural industries such as sugarcane, beef, dairy, fruit and vegetable growing. The township of Murwillumbah is located in the centre of the catchment and the large urban area of Tweed Heads surrounds the estuary. The parks and reserves within the catchment are recognised for their ancient ecological communities with evolutionary links to Gondwana.

Tweed Heads webcam
The Tweed Heads bar crossing web camera provides real-time video of conditions within the river entrance immediately offshore to help with bar crossings and boat safety.
Tweed Sand Bypass
Tweed Sand Bypassing is a joint project of the NSW and Queensland governments that aims to maintain a safe and navigable entrance to the Tweed River. It involves a sand transport system that collects sand from the southern side of the river entrance and transports it to the northern side to help maintain beaches on the Gold Coast.
