WA Labor has vowed to immediately rehabilitate the Beeliar Wetlands, where clearing is making way for the controversial Roe 8 highway extension, if it wins the state election next month.
The opposition has long vowed to tear up contracts for the project and now says it will swiftly work to restore and revegetate the wetlands to their former state.
"Clearly that needs to happen. That's a beautiful part of Western Australia there and we want to engage the community in fixing it," leader Mark McGowan told reporters.
Local councils would also be involved, he said.
Opponents to the project have had two wins in recent days.
The Greens secured a snap inquiry in Perth late next week into what it calls "repeated, unforgivable breaches of environmental conditions" at the site while Labor stalwart Alannah MacTiernan won her long-standing fight to secure documents about the project through FOI.
Mr Barnett described Labor's plan to tear up the contracts as reckless and said it would send the wrong message that the state did not honour them.
Roe 8 is the most contentious part of the largely federal-funded $1.9 billion Perth Freight Link but no final route to Fremantle Port has yet been decided upon, prompting opponents to call it "the road to nowhere".
