Projects set to start in 2023 include the replacement of seawalls at the Lakes Entrance Fish Limited Co-op (LEFL) and at the Port Welshpool Ferry Terminal, and delivery of the Cape to Cape Resilience Plan.

Jam Jerrup

  • 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.

Lakes Entrance

  • Location: Bullock Island Lakes Entrance, LEFL building
  • Timing: Construction 2023. Investigation and design completed in 2022.
  • Details: The LEFL seawall is in poor condition, impacting the LEFL building upon it. This project seeks structural engineering advice to inform the future repairs and maintenance required for the longevity of the seawall into the future.
  • Location: Northern shoreline of Cunninghame Arm, Lakes Entrance, adjacent to the Ocean Rescue (Australian Volunteer Coast Guard) building.
  • Timing: Completed June 2022.
  • Details: The old seawall protected the building foundations and foreshore reserve from erosion. Its condition had deteriorated significantly over the last three years. The new precast concrete panel and steel pile seawall offers increased protection for the reserve and Ocean Rescue buildings and infrastructure for years to come and allows for safer public access and recreation.

Loch Sport

  • Location: Eastern half of the town adjacent to Lake Victoria.
  • Timing: Report released in August 2022. Visit the Enage Victoria Loch Sport Foreshore Coastal Erosion page for more details.
  • Details: DEECA has sought feedback to help inform erosion management and adaptation measures for the Loch Sport Foreshore – visit the Engage Victoria Loch Sport Foreshore Coastal Erosion page to read the scientific study and find out more about the next steps.


  • 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.

Ninety Mile Beach

  • 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 in late 2023.
  • 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.

Port Welshpool

  • Location: Port Welshpool Ferry Terminal
  • Timing: Construction to commence in 2023. The options study and designs were prepared in October 2022.
  • Details: The Port Welshpool seawall, which protects a road and provides access to a commercial wharf and ferry services, is in poor condition. An investigation seeking structural engineering advice to inform the future repairs and maintenance required for the longevity of the seawall into the future is complete.


  • Location: Rhyll boat ramp, Phillip Island
  • Timing: First stage completed September 2022.
  • Details: Bass Coast Shire Council, with support from DEECA, completed 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). Further sections of the seawall will be completed as funding becomes available.
