Update: Protest action against a proposed gas hub at James Price Point reached Broome this morning with a man climbing an 8m pole held up by ropes that are blocking off entrances to Woodside's offices.
Broome Community No Gas campaign spokeswoman Tegan Mossop said the man on the pole was George Bishop, a local in his 20s.
She said work erecting the pole started about 4.30am in an attempt to prevent Woodside's 23 staff in Broome from entering their office this morning.
Police arrived to interrupt before the fourth and last rope could be secured to the ground.
Three move-on notices have been issued - one to Mr Bishop.
Police have also arrested three people - one for failing to give personal details to police, one for obstructing an officer and one with failing to obey an order given by police.
At least 10 police officers are at the scene and have blocked off the road near the office, to protect a large number of bystanders from traffic.
A fire engine and ambulance are on stand by.
Ms Mossop said protesters were angry Woodside continued to "work illegally" on the site of the proposed gas hub at James Price Point.
"It's hard to oppose that when the State is the proponent of the project and is changing laws to allow Woodside to work without correct permits," she said.
"They still don't have a section 18 to work on the western side of Manari Road."
Ms Mossop said the action this morning aimed to highlight the value of James Price Point, which she said was one of the world's last remaining wilderness areas.
"The gas will be gone in 50 to 60 years, but these eco systems and cultural significance will be altered forever - their value is so much more than quick dollars," she said.
A Woodside spokesman said Woodside respected the rights of people to protest, but asked that people express their views in a peaceful and lawful manner.The spokesman said although staff were currently unable to access the Broome office, they were able to work in other locations.
