After the Tweed River entrance training wall was extended, sand accumulation was no longer occurring on the beaches to the north of the wall causing significant shoreline retreat. The hydrology of the area was also affected, and sand continued to accumulate at the river entrance, making the river entrance hazardous for boats. The Tweed Sand Bypass was installed in 2001 to address these issues. The project was a joint initiative from the Queensland and New South Wales governments, as the Tweed River channel in NSW benefits from removal of sediment, and the famous Gold Coast beaches in QLD benefit from the added sand.
