Investing in the Sand Bypass System for the Future
The Gold Coast’s sand bypass system is one of the region’s most important pieces of infrastructure, quietly working every day to keep sand moving along the coastline and maintaining safer conditions for navigation at the Gold Coast Seaway entrance.
Each year, the system transfers around 500,000 cubic metres of sand from south of the Seaway to South Stradbroke Island and the northern beaches of the Gold Coast.
This helps maintain healthy beaches, protects the coastline from erosion and helps keep the Seaway safer and accessible for recreational and commercial vessels.
Keeping a system of this scale operating reliably requires ongoing investment.
Over the past year, Gold Coast Waterways Authority (GCWA) has completed a significant program of maintenance and renewal works designed to improve the long-term reliability, safety and resilience of the system.
Completed works include:
- Servicing critical pumping equipment.
- Replacing pipework, hoses, valves and other mechanical components.
- Repairing and strengthening maintenance platforms affected by corrosion.
- Improving access and safety infrastructure within the facility.
- Repairing critical deck lifting components.
- Planning investigations for a backup pumping system to improve the long-term resilience of the sand bypass system.
While most of this work happens behind the scenes, it plays a vital role in keeping the sand bypass system operating reliably and efficiently.
By investing in planned maintenance and the long-term renewal of this critical infrastructure, GCWA is ensuring the system continues to support healthy beaches, a resilient coastline and well-managed waterways for years to come.
