Perth protesters who have set up a roadblock preventing access to and from Woodside’s Burrup gas plants in the Pilbara are under fire for endangering the safety of workers trying to get home from night shift. Three protesters who travelled from Perth parked a car and trailer across the main access road to Woodside’s gas plants, Dampier Port, Yara’s operations and King Bay businesses in the early hours of Wednesday morning and chained themselves to concrete barrels. Perth resident Liz Burrow said she and fellow protesters were standing with the Ngarluma people in opposition to Woodside’s Scarborough gas development. Reuters has reported Murujuga Aboriginal Corporation is seeking a stake in the project and Pluto LNG expansion. “They can just blow up up a World Heritage amazing collection of rock art for the sake of fossil fuels that shouldn’t even be getting bought out of the ground,” Ms Burrow said. “The only way we can make a difference is to sit on the road with our arms in a barrel of concrete. “We’re staunch as hell; we’ve got food, water and we don’t give up. We’ll keep on coming back to Scarborough again.” Ms Burrow said they were willing to remain at the blockade for “as long as it takes”. Their actions have found little support online from Karratha residents, who have widely criticised the protesters for preventing staff from getting to work or home. Australian Manufacturing Workers’ Union WA state secretary Steve McCartney said the protesters’ actions had risked the safety of workers. “This isn’t a fight you need to be having with our members, the workers just want to return home or get to work safely and do their job properly,” he said. “AMWU supports the future of green manufacturing and jobs and many of our members look forward to working in green industries, but for now they need to do the jobs that are available and do them safely.” Mr McCartney’s criticism was backed up by Woodside, which on Wednesday morning said: “our teams are currently maintaining safe operations at our facilities while access to and from our sites and others, is rectified. “Woodside respects people’s rights to protest peacefully and lawfully but actions such as these that endanger the safety of others go beyond those rights.” It comes after Woodside on Tuesday announced it would press ahead with the $16.5bn Scarborough gas project, which will pipe gas from 375km off the North West coast to the company’s Burrup Hub. WA Premier Mark McGowan said the project would help power-hungry nations reduce their reliance on coal. “It will have greenhouse gas abatement program as part of it to offset large amounts of emissions but, importantly, gas is a much lower emission intensive fuel than coal,” he said. “I understand the concerns and I share many of the concerns, in fact, I share all the concerns about greenhouse gases. “If you ever go to China or Japan or Europe or America, or India you’ll know that coal burning is a big problem.” But the announcement drew immediate fire from conservationists who have vowed to lead a strong campaign against the project which they say will pump 1.69 billion tonnes of carbon dioxide into the atmosphere and damage nearby rock art which is subject to a World Heritage push. “At a time when the world is facing up to the dire need to reduce emissions and prevent irreversible damage to our climate, this project is an insult to ordinary Australians who will bear the brunt of future extreme weather events and climate disasters caused by developments like Scarborough,” Conservation Council of WA executive director Maggie Wood said. Pilbara District inspector Mark Tobiassen said the protest had not completely stopped access to sites. “Industry have a legal right to work and the employees work for industry and this block here on the road today has prevented that for a period of time,” he said. “Our focus is safety — it’s hot, it’s windy and there’s a lot of sun so we need to make sure that they're safe. “We have specialist people trained to deal with these kinds of things coming up from to assist us to (remove them) safely.” The protesters have warned there were “many others” to take their place should they be hauled away. Woodside chief executive Meg O’Neill on Tuesday said the gas field had a very low carbon content and the company must think of customers who want to use LNG as a transition fuel. Pilbara Ports Authority, Yara and Murujuga Aboriginal Corporation have been contacted for comment.
