Cockburn Sound

What is it?

Cockburn Sound is Western Australia’s most important recreational fishing waterway and one of our State’s most valuable marine environments. It has played a central role in Western Australia’s fishing culture for generations.

Protected by Garden Island, the Sound provides accessible, safe and reliable fishing opportunities for families, small boats, kayaks, divers and shore-based fishers. It is home to iconic fishing locations including the D9, Parmelia Bank and The Pinnacles, and supports Western Australia’s busiest boat ramp.

In addition, Cockburn Sound is one of WA’s most significant marine ecosystems. It supports the largest pink snapper spawning aggregation in the West Coast Bioregion, provides important nursery habitat for many fish species and continues to recover following the historic loss of much of its seagrass habitat.

Why it matters

As Western Australia continues to grow, Cockburn Sound will also support a range of major defence, transport, port and industrial developments, making careful planning and environmental stewardship more important than ever.

There is an important opportunity to ensure that the environmental, social, and recreational fishing values that make the Sound so special are protected and enhanced as these projects progress.

For Recfishwest, success means future generations continue to enjoy healthy fish stocks, quality fishing experiences, ongoing access, and that efforts to support restoration and environmental improvements in Cockburn Sound are not undermined by development.

What Recfishwest is doing

Recfishwest doesn’t simply respond to change in Cockburn Sound – we work to shape better outcomes.

For decades, we’ve worked alongside governments, regulators, researchers, industry and the community to protect and improve Cockburn Sound for recreational fishers and future generations.

As Cockburn Sound continues to undergo change, our role is to ensure recreational fishing interests are properly represented throughout planning and decision-making. While decisions regarding development ultimately rest with governments and statutory decision-makers, we engage constructively and independently to secure the best possible outcomes for the Sound.

Our commitment isn’t just reflected in what we say – it’s demonstrated through the projects, partnerships and advocacy we continue to deliver across Cockburn Sound.

Featured Projects

Snapper Guardians

Following the 2015 fish kill in Cockburn Sound, Recfishwest launched the community-funded Snapper Guardians program to help restore one of Western Australia’s most important pink snapper fisheries. Since then, hundreds of thousands of juvenile pink snapper have been released into Cockburn Sound with the support of thousands of Western Australians.

Mussel Farming – Creating Better Habitats

Recfishwest is helping pioneer innovative habitat enhancement through expanding mussel farm production.

Working alongside Byssal, researchers and project partners, we’re supporting the establishment of native mussel systems that increase biodiversity and create new habitat and food for fish and other marine life. These projects demonstrate how nature-based solutions can contribute to a healthier Cockburn Sound and support better fishing outcomes.

Protecting Spawning Pink Snapper

Cockburn Sound supports the largest pink snapper spawning aggregation in Western Australia’s West Coast Bioregion.

For decades, Recfishwest has advocated for measures to protect this iconic fishery, including supporting seasonal spawning protections and investing in long-term recovery initiatives that benefit both fish populations and fishers.

Mussel seeding

The purpose of marine rockwalls is not to provide marine habitat.

However, through the Byssal project, Recfishwest is supporting mussel seeding to transform artificial marine infrastructure into productive habitat for mussels, algae, invertebrates and fish. These living walls help improve biodiversity, provide food for fish such as pink snapper, and demonstrate practical ways to enhance marine ecosystems in developed coastal environments.

Shaping Better Outcomes

Recfishwest continues to engage with governments, regulators, Defence, industry and project proponents to ensure recreational fishing values remain at the forefront of planning for Cockburn Sound.

Our focus is simple: where development occurs, we will advocate to avoid impacts wherever possible, minimise unavoidable impacts, restore affected habitats and deliver enhancements that leave Cockburn Sound healthier and more productive than before.

By combining practical on-ground projects with constructive advocacy, we are working to ensure Cockburn Sound remains one of Western Australia’s premier recreational fishing locations for generations to come.
