Noosa Main Beach Seawall Design
Noosa Council is undertaking a new project to design a future replacement of the Noosa Main Beach seawall.
The current seawall is over 50 years old (pictured, right, during construction) and was not designed or constructed to the standard needed to continue withstanding weather events that are going to worsen over time due to climate change.
A compromised seawall significantly reduces the resilience of Noosa Main Beach foreshore to withstand expected rises in sea levels and storm tides.
The new design will improve the seawall’s strength to boost the precinct’s resilience to natural disasters and rising sea levels due to climate change.
This project is for the design phase only. Construction will rely on the availability of funding.
Information Sessions
Noosa Council is holding a series of Information Sessions to keep the community informed about the project.

Background and FAQs
What is a seawall?
A seawall is a structure that separates land and water, designed to prevent coastal erosion and other damage from wave action and storm tide inundation.
Why is a new seawall needed?
The existing Noosa Main Beach seawall is over 50 years old and technical reviews show the wall is degrading at a rate of three percent per year due to wear and tear and less-than-ideal rock choice. The movement of the rocks over time has also significantly reduced the resilience of the Noosa Main Beach foreshore.

When will design be completed?
It is anticipated the design process will take about seven months, with completion at the end of 2025.

What is not included in the design?
All aspects relating to parking and traffic flow are outside the scope of this project.
When will construction of the new seawall start?
The timing for construction of the new seawall has not been determined and is not part of this project. Timing for construction will depend on Council securing funds from the Australian and Queensland governments after design is complete. We appreciate the construction phase will require careful planning and this is being considered as part of the design process.
