Lake Macquarie City Council is leading a significant project to address the ongoing issue of sand build-up in Swansea Channel, the crucial entrance to Lake Macquarie. This initiative involves the design, supply, and delivery of a new dredge vessel and sand transfer system, aiming to ensure safe access for vessels navigating the channel.
Expected to be operational by mid-late 2026, the dredge will have the capacity to remove more than 1,000m3 of sand per day, with the dredged sand being pumped to the northern end of Blacksmiths Beach. The project has received $10 million in funding from the Australian Government’s Priority Community Infrastructure Program, which also includes upgrades to the Blacksmiths boat ramp.
Swansea Channel has a history of sand build-up, posing challenges for larger vessels. Periodic dredging is essential to maintain a navigable channel, ensuring safety and enhancing tourism and recreational activities around Lake Macquarie.
The dredge vessel, a Beaver 30 supplied by Birdon Pty Ltd, is a proven and efficient suction dredge capable of high daily sand removal rates. Remote monitoring features will enable real-time performance tracking, enhancing operational reliability.
Additionally, a sand transfer system will pump dredged sand from a station east of Naru Point to Blacksmiths Beach, contributing to ongoing channel maintenance. The system’s installation and routing are currently under investigation to optimize efficiency and minimize environmental impact.
Alongside the dredging project, the Blacksmiths boat ramp will undergo a $1 million upgrade funded by the Australian Government. The enhancements include new pontoons, lighting, and other amenities to improve boating facilities in the area.
The timeline for the project outlines key milestones, including the commissioning of the dredge vessel by mid-2026 and the subsequent handover of operational responsibilities to Transport for NSW. The dredging activities are expected to occur several times a year, with the potential to remove significant volumes of sand during each campaign.
Environmental considerations are paramount, with measures in place to minimize impacts on marine habitats and water quality. The dredging operations will be conducted with care to avoid sensitive areas and protect the ecosystem.
Overall, the Swansea Channel dredging project represents a crucial investment in maintaining vital waterway access and enhancing the safety and sustainability of marine activities in Lake Macquarie.
