Project timeline
Design completion: October 2026
Expected construction start: Winter 2027
Community update
Obtaining the required approvals from external authorities have presented a significant challenge to the delivery of this project. As a result, the anticipated construction commencement date has been revised.
Council is continuing to work closely with the relevant authorities to progress and expedite the approval process to enable the project to move into the construction phase as soon as possible.
We appreciate the community's patience and understanding while these matters are being resolved.
Project scope
We are reconstructing the groynes near the boat ramp to prevent sand movement and increase the usability of the boat ramp. The work includes:
- Adjusting the height of existing groynes to mitigate sand movement into the boat ramp.
- Improving and expanding the vegetated area on the eastern side of the boat ramp.
This will improve accessibility and usability for local boaters and visitors, while also supporting our emergency services access to Botany Bay.

Funding
This project is fully funded by Sutherland Shire Council.
Frequently Asked Questions
A groyne is a rock or concrete structure built out from the shoreline. It helps control sand movement along the beach, protecting the shoreline and keeping areas like boat ramps clear and functional.
The current groynes have aged and are no longer working effectively. Sand has been moving into the boat ramp area, making it harder for people to launch and retrieve their boats. Upgrading the groynes will restore their effectiveness.
Our design completion is contingent upon receipt of the necessary authority approvals. We are planning for the construction to start during the Winter of 2027, subject to approvals and weather permitting.
- Reduced sand build-up around the boat ramp
- Improved safety and ease of launching boats
- Better long-term protection of the shoreline and ramp area
- Increased usability for the community
The boat ramp may be temporarily restricted during certain stages of the work.
Clear signage and community updates will be provided in advance of any closure.
Visitors are encouraged to explore other suitable alternative locations prior to their travel out to Bonna Point.
Adjusting the groyne height is stage 1 of the remediation work. The sand build-up should be minimised in the area of the boat ramp. This will reduce the frequency of required maintenance.
We will continue to monitor the sand movement to ensure the boat ramp functionality is maintained.
