A Perth resident labelled by the Pilbara’s top cop as a “professional protester” has pleaded guilty to three charges relating to November’s Burrup blockade. Caleb Houseman appeared before Karratha Magistrates Court on Tuesday, charged with failing to obey a move-on notice, unreasonably obstructing a carriageway, and obstructing a public officer. Karratha police arrested the man, along with co-accused Elizabeth Burrow and Petrina Harley, on November 24 after a 14-hour protest which blocked access to key industrial sites on beaches on the Burrup Peninsula in protest of Woodside’s decision to green-light the Scarborough gas project. It is alleged the trio parked a car and trailer across the road and that Houseman locked himself to the blockade, with his co-accused Ms Harley and Ms Burrow putting their arms in concrete. Pilbara District Supt Kim Massam told the ABC the group were “professional protesters”. “We’re very disappointed to see the appearance of Perth-based protesters,” he said. “It wasn’t just Woodside that these protesters affected — it was a broader community, it was small businesspeople trying to do their job, going around the Pilbara. “They were impacted by some people with some ideology that can very well be expressed in a better form than putting themselves and others in danger.” The court heard the accused were given multiple move-on orders, the first of which was at 1.50pm, before they complied at 5.40pm. Houseman will next appear before the Perth Magistrates Court on December 20. His co-accused Ms Harley and Ms Burrow were granted bail on November 25 and will appear before the Karratha Magistrates Court on January 5.
