Tweed River Entrance Sand Bypassing Project
The Tweed River Entrance Sand Bypassing Project (TRESBP) is a joint initiative of the Queensland and New South Wales governments to establish and maintain a navigable entrance to the Tweed River while providing an ongoing supply of sand to the southern Gold Coast beaches.
Project feasibility reports
A feasibility assessment into options to improve the long term operation of the Tweed River Entrance Sand Bypassing Project (TRESBP) was jointly announced in July 2009 by the Queensland Minister for Climate Change and Sustainability and the NSW Minister for Lands.
Both governments have been working closely to investigate potential operational improvements to better manage the delivery of highly variable sand to Gold Coast’s southern beaches. Engineering consultants GHD and BMT-WBM were commissioned to undertake the feasibility investigations. The report outlines potential operational improvements to enhance the long-term capability of the system (TRESBP).
Potential operational improvements investigated include:
- North Kirra outlet—extend the existing sand pumping and delivery to a new outlet at North Kirra
- Additional dredge placement areas—potentially located along Bilinga and Tugun beaches, about three kilometres to the north of the project placement areas. Also, in deeper waters further offshore of the existing Point Danger to Coolangatta nearshore sand placement areas
- Kingscliff sand delivery—consider the Tweed River entrance as a one-off source of sand for proposed beach nourishment works of the eroded south Kingscliff Beach proposed by the Tweed Shire Council
- Sand back-passing—develop a dredging and/or pumping regime to allow sand to be recycled to southern Letitia Spit
Community consultation
The consultation period has now closed. Feedback in response to TRESBP will help inform the development of a long-term solution for the project, which is due to be released in 2012.
