Another legal challenge to the controversial Roe 8 highway extension is set to be lodged in the Supreme Court of Western Australia.

Traditional owner Corina Abraham is expected to lodge the challenge today against the West Australian Government's process for granting Aboriginal heritage approval, arguing it is flawed.

The Aboriginal Cultural Materials Committee (ACMA) recommended in February 2013 that an application to disturb registered sites to make way for the extension be rejected, because of the spiritual significance of Bibra and North lakes.

However in June last year, the committee reconsidered the application and recommended it be approved.

A custodian from Whadjuk Noongar country, Ms Abraham said she was challenging the approval by serving writs to Aboriginal Affairs Minister Peter Collier and the ACMA.

"I'm challenging the section 18 approval because it's who I am and it's where I come from, and it's what connects me to my country," she said.

"It's what my grandparents, my parents and ancestors taught me. It's my culture, it's what makes me strong as a Noongar person."

Ms Abraham, 39, said the site for the highway ran through culturally significant areas.

"Bibra Lake, which is to us as Noongar people Lake Walliabup, and North Lake, which is Lake Coolbellup, are within the Beeliar wetlands," she said.

"Those lakes mean a lot to my people. My ancestors camped there, they were born there.

"This place is important for me as a Noongar person as Kings Park or Anzac Cove is for non-Aboriginal people."

Mabo barrister to argue case

"I'm hoping that the Minister will go back to his drawing board and actually see what's documented in our history," Ms Abraham said.

"See the significance of this area culturally and see what it actually means to us as Noongar people and stop construction forever."

Roe 8 is the first stage and a key part of the $1.6 billion Perth Freight Link project, which seeks to build a byway for heavy haulage from Perth's eastern industrial suburbs through to Fremantle Port.

Ms Abraham's bid follows a successful challenge by the Save Beeliar Wetlands group that saw the environmental approvals for the project ruled invalid late last year.

The State Government is appealing against that decision, with the case set to be heard in May.

Greens MP welcomes challenge

Greens MP Lynn MacLaren has repeatedly questioned that decision in Parliament and said the Government had failed to give a convincing explanation.

"I therefore welcome Ms Abraham taking on the onerous and potentially intimidating task of challenging the Minister and ACMC through the Supreme Court," Ms MacLaren said.

"It is a sign that a government has lost its way when ordinary people have to take the Government to court for flawed process."

The Department of Aboriginal Affairs has been contacted for comment.
