Artificial reef and seagrass commitments welcomed – although Cockburn Sound dredging and access concerns remain

The State Government’s announcement of $17.4 million for social and environmental initiatives in Cockburn Sound has been welcomed by Recfishwest.

Among the initiatives being funded are new artificial reefs and more seagrass restoration — two measures Recfishwest has long supported.

Recfishwest CEO Dr Andrew Rowland said, “We welcome the Government’s commitment to artificial reefs and seagrass restoration – both are proven tools for supporting healthy marine ecosystems and better fishing.

“We’ve advocated for these initiatives for some time and it’s good to see them get a guernsey in this budget.”

Cockburn Sound artificial reefs – have your say

The Government’s Westport program is seeking community feedback on the best location for the reefs. Recfishwest encourages all metro fishers to have their say – click here to access the survey.   

As seen with artificial reef deployments in Dunsborough (left), the Rottnest Towers (centre) and Esperance (right), artificial reefs deployed in Cockburn Sound could see similar marine life benefits.

Ongoing concerns about dredging

While we welcome these habitat initiatives, serious concerns remain about the potential impact of the dredging that will be required to create the new port and a new shipping channel that will service it.

What you need to know about the dredging

It’s going to be on a large scale to deliver the new port and the new shipping channel. To create the planned 20km long, 18.5m deep shipping channel running from Cottesloe to Cockburn Sound will require up to 35 million m³ of ocean habitat to be dredged, potentially making it among the biggest dredging operations ever to be undertaken in Australia.
There’s little detail at this stage about the dredging program required to deliver the development adding to our concerns about its potential impact.
It will be subject to environmental approvals from the Environmental Protection Agency following a Public Environmental Review due to take place next year.
If approved, dredging could start as early as 2028.
As seen in this map on Westport’s website, there is a huge amount of dredging planned to make way for the port and shipping channel from Cottesloe to Cockburn Sound, making it among the biggest dredging operations in Australian history with serious potential impacts on the environment and fishing.

 

“The sheer scale of dredging and the plume it will create is the most concerning aspect of the Westport project,” said Recfishwest CEO Dr Andrew Rowland.

The international experience has shown dredging can have massive impacts on the environment. Even after the dredgers leave, it can take decades — or longer — for marine ecosystems to recover. In some cases, they never do.

Dredging increases turbidity, reduces light penetration and smothers seagrass meadows which are vital habitat for species like snapper, crabs, whiting, herring and squid.

It’s a concern that is shared by the Westport developers themselves – Westport Managing Director Patrick Seares told the ABC in a recent interview, “We realise this is a public project led by the public, by the Government for the public – so we’ve got to take care of their assets.

“For us it’s about managing the dredging program, the plumes coming out of dredging and making sure we protect the Sound through that.”

Recfishwest will continue to advocate for the long-term health of the Sound and the safe, accessible and much cherished fishing experiences it supports for thousands of fishers.

“We’ll keep supporting positive habitat outcomes,” said Andrew, “but we’ll also keep pushing for clarity and accountability around environmental impacts and will fight to maintain and improve Cockburn Sound.”
