The Roe 8 controversy is shaping up to be one of the defining issues of March’s Western Australian state election. It has split the major parties and attracted ongoing and acrimonious protest, with police being accused of using heavy-handed tactics in dispersing protesters. But what does the project actually involve, and what has got its opponents so riled? 

What is the Roe 8 project?

“Roe 8” refers to a $450 million extension of the Roe highway from its current end at Kwinana Freeway in Jandakot to Stock Road in Coolbellup, roughly 10 kilometres south-east of Fremantle.

It would be WA’s first toll road, and represents the first stage of the $1.6 billion Perth Freight Link,which was announced by the Barnett government in May 2014, a heavy-haulage route designed to get freight to Fremantle Port. The link is 60% funded by the Commonwealth.

The WA government says building Roe 8 will ease congestion by taking 2000 trucks off Leach Highway between the freeway and Stirling Highway each day, and thousands more off other surrounding roads.

What’s the source of the controversy around Roe 8?

The extension would run through the Beeliar Wetlands, requiring the bulldozing of roughly 100 hectares of bush land. This has drawn the ire of conservationists, academics, indigenous groups and local residents. Oh, and singer John Butler.

WA Labor has promised to scrap the project if the party wins the upcoming election, and federal Opposition Leader Bill Shorten promised to pull Commonwealth funding in the lead-up to the the 2016 federal election.

“Roe fails politically, practically and environmentally,” Kate Kelly, convener of the Save the Beeliar Wetlands (SBW), said.

The group has launched a series of court cases attempting to stop the extension.

What was argued in court?

In December 2015, SWB argued in the Supreme Court that WA’s Environmental Protection Agency had not followed its own policies in recommending that Environment Minister Albert Jacob approve the extension. This was successful, with Chief Justice Wayne Martin finding the approval invalid, and the project was halted.

However, this was unanimously overturned in the Court of Appeal the following July, with then-president of the Court of Appeal Carmel McLure handing down the ruling that the EPA was not legally required to follow its own policies, on the grounds that they are not “mandatory relevant considerations”.

SWB filed for special leave to challenge the decision and applied for an interim injunction on construction work. In January this year, that was also knocked back.

What are the environmental implications?

The major crux of the environmental argument is is the wildlife that will be affected. The Beeliar Wetlands is home the Carnaby’s black cockatoo, Baudin’s black cockatoo and the forest red-tailed black-cockatoos.

Bird conservation organisation Birdlife Western Australia’s 2016 Great Cocky Count report stated:  

“At the state level, all three black‐cockatoos are listed as fauna that are ‘rare or likely to become extinct and therefore in need of special protection’ under the Western Australia Wildlife Conservation Act 1950. The Western Australian Threatened Species Scientific Committee has classified the Forest Red‐tailed Black‐ Cockatoo as vulnerable, and Carnaby’s Black‐Cockatoo and Baudin’s Black‐Cockatoo as endangered.”

What is the government’s defence?

The Main roads Land Acquisition and Management Plan for Roe 8 identified Lake Clifton as a potential offset site — claiming that it contained “529 ha of Carnaby’s Black Cockatoo foraging habitat and 252.6 ha of Red-tailed Black Cockatoo foraging habitat”.

In a statement on January 9, responding to the most recent court decision, Jacob claimed that 78 hectares of the total 97.8 hectares that would be cleared for Roe 8 is black cockatoo habitat, and that “the State Government is providing 624 ha of offset land containing black cockatoo habitat”.

Professor of environmental management at Edith Cowan University William Stock was engaged as by SBW’s lawyers as an expert witness. His assessment of the EPA’s offsetting provisions was submitted as an affidavit in support of the injunction, December 2016. He believes the plan is unclear, internally inconsistent and its conclusions are not supported by its content. He contrasts the assertion on page 8 that there is 459.6 hectares of potential Carnaby’s black cockatoo foraging habitat within the offset area, with a later table that states Lake Clifton only has 77.84 hectares of good-quality Carnaby’s black cockatoo habitat.

“This issue is emblematic of the broader issues of offsetting,” Stock told Crikey.  “Research has shown that all remaining Banksia woodland is already being used as a food source, so adding more of this vegetation type to the conservation estate is good for conservation, but if it doesn’t maintain the extent or add to the foraging area there is still a net loss of habitat.

“This is not a real offset since it is not providing like for like or better.”

A spokesperson for EPA told Crikey the agency considers offsetting only as a last resort when avoiding or mitigating environmental impacts where impossible.

“In the case of the Roe Highway Extension proposal by Main Roads Western Australia, the EPA assessed the significant impacts of the proposal after all steps had been taken by Main Roads to avoid, minimise and mitigate environmental impacts,” the EPA said.

“Having considered the impacts of the proposal, the EPA recommended strict conditions incorporating a package of offsets including restoration works and acquisition of at least 234 ha of potential foraging habitat for black cockatoos; at least 7.5 ha of potential breeding habitat and at least 7 ha of Conservation Category Wetland areas and an appropriate buffer.

“The EPA’s advice and subsequent Ministerial Approval effectively ends the EPA’s role and jurisdiction.”

Where is the project now?

Despite the controversy and Labor’s promise to halt the project, clearing and the attendant protest continues

“I think [the continuation of clearing] supposed to be more psychologically demoralising, rather than practically efficient,” Kelly said. “But it’s had the opposite effect, it has energised people who were already protesting, and even people who are in favour of [Roe 8] think the clearing shouldn’t continue this close to the election.”


Australia has spoken. We want more from the people in power and deserve a media that keeps them on their toes. And thank you, because it’s been made abundantly clear that at Crikey we’re on the right track.
