South Mollymook Coastal Protection Works
Council has been investigating a new seawall at South Mollymook Beach to help address current and future coastal hazards.
We have now finalised the detailed engineering design for a new seawall following the completion of technical investigations, environmental assessments and community consultation.
The purpose of the new seawall is to ensure long-term protection of the essential public infrastructure at South Mollymook Beach and mitigate the risk of coastal hazards.
At risk infrastructure along South Mollymook Beach includes (view on map):
- Golf Avenue and Ocean Street road easement
- Stormwater outlet/culvert on Golf Avenue
- Shoalhaven Water sewerage pump station and easement south of the Golf Club
- Foreshore pedestrian pathway and beach accessways
- Mollymook Golf Club – building and carpark (funding partnership opportunities to be investigated)
- Mollymook Surf Life Saving Club and beach access ramp
- Existing seawall structures.
Background
Mollymook beach is flanked by urban development and in some areas, the frontal dune has been interfered with, reshaped, and denuded of natural vegetation. At the southern corner of the beach there is currently near 300 meters of varied seawalls extending from the sewage pumping station south of the Mollymook Golf Club (MGC) building to the Surf Lifesaving Club (SLSC) boat ramp. This coastal protection infrastructure has been previously impacted by major storms and East Coast Low events such as those which occurred in 2015, 2016, 2020 and 2025, and is nearing the end of design life.
As set out by Council’s Coastal Management Program for the Open Coast and Jervis Bay replacement of existing seawalls is the preferred option to mitigate the risks of coastal hazards on essential public infrastructure, as well as the MGC. This will improve amenity, safety and ensure protection from current and future coastal hazards.
A Detailed Design has been completed for this project which will inform Councils investigation and determination of funding for planned construction.
Project Stages
In 2025, Council completed a grant funded partnership with the Department of Climate Change, Energy, the Environment and Water (DCCEEW) to complete development of all pre-construction requirements. This work included the detailed engineering design, environmental assessment, community consultation and required agency approvals for the replacement of the existing seawalls at South Mollymook beach.
Council is currently investigating potential funding opportunities for construction..
Community Engagement
A variety of methods will be used to inform the community on the progress of this project. Details for all community engagement dates and options will be made available as the project progresses.

Council have been working with the Project Design Team to review feedback received during stage two of community consultation. Landscape Architectural design has been developed to enable an incorporation of natural and social amenity features to the coastal protection infrastructure.
Now informed by the proposed architectural inclusions, Council's appointed design consultants, Advisian, have commenced detailed engineering design activities.
The Landscape Architectural Concept Drawings are being finalised through this detailed design program, which will conclude all pre-construction components for the project. The final design is planned to be on exhibition for public comment in early 2024.

Councils’ community feedback survey for the concept design public exhibition closed on Friday 14 October. Council would like to thank the community for their participation in this consultation stage of the South Mollymook Coastal Protection Works. The feedback received has been reviewed for consideration as the project progresses into the detailed design phase.
To ensure the community knows your feedback has been heard, here are some of the key themes that came out of the consultation.
Of the 55 Community responses received, the majority of respondents were supportive of the proposed design. Comments received from all respondents noted a preference for the inclusion of green space or non-linear features in the wall to help reduce the bulk-concrete look and heat effects during summer. Additionally, all ability access and broader inclusion of varied amenity facilities were requested.
Council will be working closely with the Project Design Team to determine the appropriate mix of amenities and functionality in the final design, with the primary objective of the Coastal Protection Works to protect and retain the essential public infrastructure at South Mollymook against current and future coastal hazards. An all-ability access ramp will be provided as part of the infrastructure upgrades. The Project Team is also investigating solutions to maximise a green, natural and amenable design, particularly across the concrete bleacher section of the wall. Upgrades to the broader foreshore landscape and beach facilities, within the vicinity of the coastal protection structure, are being considered separately from these works.
We look forward to exhibiting the Final Design in early 2023 for further feedback and encourage you to subscribe to this page to receive project updates.

In January 2022, Council commissioned the consultancy team of Advisian Pty Ltd to commence the South Mollymook Coastal Protection Work project.
This engagement will address all pre-construction components of this project, including detailed design, associated agency approvals, environmental assessment, and community and stakeholder consultation. This engagement is anticipated to take approximately 9 months. Community and stakeholder engagement will be included to ensure support throughout design development is achieved.
How can I be involved?
Initial community consultation sessions are expected to be scheduled in early-mid 2022. Further stakeholder engagement, and exhibition of the design, will be scheduled during design development and at the design finalisation stages of this project. Details will be provided once confirmed.
Council is excited to work alongside the highly experienced and professional team at Advisian to develop a design for essential coastal protection at one of the region’s most popular beaches.
