Westport Kicks Off Feasibility Study on New Artificial Reefs in and around Cockburn Sound

Westport has commenced a feasibility study to explore the potential for new artificial reefs in and around Cockburn Sound.

Cockburn Sound is a vital ecosystem and recreational area for Western Australians, and Westport is committed to enhancing its long-term health and value for future generations. The feasibility study will evaluate whether new artificial reefs can deliver local environmental and social benefits – two of our Westport Goals.

Project Overview

Artificial reefs are man-made underwater structures designed to mimic the functions of natural reefs. When carefully planned and positioned they can provide habitat for marine life, support biodiversity, enhance recreational opportunities such as fishing and diving, and in some cases, assist with coastal protection.

The feasibility study will include:

A constraints analysis to identify potential locations in and around Cockburn Sound where artificial reefs may be feasible.
Stakeholder and community engagement to receive feedback on potential artificial reef locations, their intended purpose and if there is overall community support.

Have your say

Community engagement is a central element of the feasibility study. Input from fishers, divers, local clubs and organisations, conservation groups, and residents will help us understand the community’s wishes and ensure this work delivers shared value and benefits.

Westport is inviting community feedback through a short online survey. If the project progresses beyond the feasibility stage, further technical work and community consultation will be undertaken to inform future planning and design stages.

Frequently Asked Questions - Artificial Reefs

What are artificial reefs?
Artificial reefs are purpose-built structures placed on the seabed to create, restore, or enhance marine habitat. They are designed to support marine biodiversity by providing shelter, feeding opportunities, and altering the water flow to attract a variety of marine species. These reefs are typically made from materials such as specially designed concrete modules, steel structures, or natural rock. In addition to ecological benefits, artificial reefs can also enhance recreational activities such as fishing and diving.

Why are artificial reefs being considered?
Scientific research completed through the WAMSI-Westport Marine Science Program shows that artificial reefs are highly valued by the community and stakeholders for the environmental and recreational benefits they can provide.

Through consultation with local community members, government agencies, and environmental organisations, artificial reefs have been identified as a promising initiative that may help support the long-term health and resilience of Cockburn Sound.

What are the benefits of artificial reefs?
Artificial reefs can offer a wide range of benefits, including:

Creating or enhancing habitat for fish and other aquatic animals
Enhancing opportunities for recreational fishing, diving, snorkelling and eco-tourism
Restoring, mitigating or offsetting damage to or loss of natural reefs or habitats
Providing coastal protection against erosion
Offering platforms for scientific research and ecological monitoring

Is the artificial reef feasibility study related to Westport’s environmental impact assessment?
No, the feasibility study is a separate project focused on exploring whether artificial reefs could be a viable initiative for Cockburn Sound.

This feasibility study is not part of the environmental impact assessment of Westport’s proposed port and marine infrastructure, which is currently underway with the State regulator.
