• Location: Jam Jerrup
• Timing: Mangrove plantings completed in February 2022. Revetment and earth works completed in July 2021.
• Details: The Jam Jerrup coastline has been experiencing significant erosion that is impacting on native vegetation, public access and safety in the area.

DEECA, in partnership with the Bass Coast Shire Council, University of Melbourne and Lang Lang Foreshore Reserve Committee of Management, has developed an erosion management plan that focuses on a hybrid approach to combat erosion in the area.

Different methods of hard-structure coastal defence, including an extension of the existing rock revetment, have been combined with a trial planting of mangroves – a nature-based method led by the University of Melbourne.

A 150-metre rock revetment has been placed to extend the existing revetment and avoid further terminal scouring, alongside earthworks to cut and reshape the cliff face to make the site safer.

Over 150 mangroves have been planted in concrete planter clusters, which will be monitored and maintained by the University of Melbourne for the next three years.

• Location: Bullock Island Lakes Entrance, LEFL building
• Timing: Construction tcommenced July 2024.
• Details: The LEFL facility is located on the south-eastern side of Bullock Island and adjoins the LEFL buildings along the eastern edge. The seawall is in fair condition however there is significant scour at the base of the seawall.

Gippsland Ports are delivering works to remediate the LEFL seawall on behalf of DEECA. The works are required to mitigate risk associated with the deterioration behind the structure and of the structure itself. The delivery of the works by Gippsland Ports will enable efficiencies in delivery and minimising any impacts on LEFL and port operations.

Construction of the seawall remediation works began in July 2024 and is due for completion in December 2024.

Location: Lang Lang Foreshore Reserve

Timing: 2024

Details: Coastal adaptation pathways planning commenced in January 2024 with a consultant undertaking these works in consultation with DEECA and the Lang Lang Foreshore Reserve Committee of Management. Adaptation planning will allow DEECA and land managers in the area to better understand coastal risks and hazards and start developing adaptation options and plans for the foreshore reserve.

Lang Lang Forshore Caravan Park Frequently asked Questions December 2024

• Location: Eastern half of the town adjacent to Lake Victoria.
• Timing: Report released in August 2022, Engagement Findings released in Octboer 2022.
• Details: Following the release of the Loch Sport Coastal Processes and Options Assessment, DEECA sought feedback to help inform erosion management and adaptation measures for the Loch Sport Foreshore. We have reviewed all feedback and a summary of the survey findings is available Loch Sport Coastal Erosion Engagement Findings, October 2022.

Visit the Enage Victoria Loch Sport Foreshore Coastal Erosion page for more details.

• Location: Eastern half of the town adjacent to Lake Victoria.
• Timing: Project commenced in May 2023 and was finalised in June 2024.
• Details: DEECA engaged consulting firm BMT Commercial Australia Pty Ltd and FSC Range to commence action on the immediate steps recommended in the 2022 Loch Sport Foreshore Coastal Processes & Options Assessment.

This work involved:

• Detailed topographic survey and aerial photography to support the design of immediate actions
• Landslide Risk Assessment conducted on the 550 metre stretch along the high dune bluff area (identified in the 2022 report as Areas 4 and 5)
• Protection requirements and Options Assessment for Areas 4 and 5
• Concept designs for walking track relocation in highly impacted sites
• Options assessment for protection of the Seagull Drive boat ramp car park. Note that this area replaced "Area 7" in the original report due to Area 7 being Council freehold land, and the Seagull drive car park experiencing an exacerbation of erosion since the 2022 report
• Sediment sampling to inform borrow sites for renourishment works.

Finalised project deliverables:

High Dune Bluff area:

• Detailed lidar survey and aerial photography
• Landslide risk assessment
• Detailed designs and drawings of the walking trail pathway realignment
• Victorian Common Funding Agreement with Loch Sport Foreshore Committee of Management for reinstatement of walking trail
• High dune bluff protection options assessment
• Sediment sampling to inform potential sand sources
• Coastal Acid Sulfate Soil (CASS) testing
• Detailed design drawings and technical specification for beach nourishment work proposed at the base of the High Dune Bluff
• Detailed design drawings and technical specification for a staged installation of a groyne field proposed for the base of the High Dune Bluff.

Seagull Drive area:

• Boat ramp and carpark protection options assessment
• Geotechnical investigations
• Marine ecology survey
• Victorian Common Funding Agreement with Gippsland Ports for the beneficial reuse of sand at Seagull Drive
• Detailed design drawings and technical specification for a small groyne field proposed for Seagull drive boat ramp car park.

• Location: Betka River mouth, south of Mallacoota
• Timing: Completed June 2022.
• Details: The 70-metre Betka Beach timber seawall was damaged in the 2019-2020 bushfires. DEECA replaced the seawall with a horizontal concrete seawall of the same dimensions and with design improvements to meet fire safety specifications and boost its resilience to extreme weather events. The passive recreational vessel access ramp and staircase have also been replaced with fireproof structures.

• Location: a 25-kilometre strip of land located between Bass Strait and Lake Reeve that extends north of the Honeysuckles to Paradise Beach.
• Timing: Acquisition of high-priority lots will commence early 2024.
• Details: DEECA is working with partners to achieve a long-term solution for affected lots at Ninety Mile Beach.
• Visit the Ninety Mile Beach Compulsory Acquisition Program webpage for more information about this project.

• Location: Port Welshpool Ferry Terminal
• Timing: Construction completed in December 2023.
• Details: The Port Welshpool seawall, which protects a road and provides access to a commercial wharf and ferry services, has been replaced

The design for the new seawall involved a full rock revetment remediation to reduce impacts on coastal processes due to higher energy absorption capability and less wave reflection.

Construction of the seawall remediation works began in August 2023 and were completed in December 2023.

Aligned with the original masonry seawall, the new seawall is approximately 114 metres long and has a design life of 50+ years. It ensures the continued use of the jetty for both recreational and commercial use. Additionally, the new design provides a more diverse habitat compared to the previous masonry seawall.

• Location: Rhyll boat ramp, Phillip Island
• Timing: Stage 1 completed September 2022, stage 2 commenced August 2024.
• Details: Bass Coast Shire Council, with support from DEECA, completed Stage 1 of a new concrete panel seawall to replace an existing 85 metres of seawall at Denne Bight, Rhyll. This project was part of the redevelopment of the Rhyll Boat Ramp Facility that Bass Coast Shire delivered in partnership with Better Boating Victoria (BBV).

Stage 2 works will include the replacement of 45 metres of the existing north side seawall, footpath, kerb and a viewing platform. This will prevent the risk of existing seawall failure and improve access and safety for pedestrians.

Over the past two years, we've been working with Bass Coast Shire Council in response to community concerns about coastal erosion and Silverleaves. Short-term sand renourishment works and a coastal processes study was completed in August 2024. The study has provided us with a deeper understanding of the forces within the coastal environment at that affect the shape of the coastline and importantly how this process is likely to progress over time.
