Police yesterday used specialist officers and a cherry picker to move protesters at several roadblocks along the route to Woodside's $30 billion gas hub at James Price Point near Broome.
Roads were closed as officers worked to remove two people suspended from trees while connected to cables crossing the road and others who had locked themselves to cement drums.
A woman had positioned herself on top of an 8m makeshift tower.
More than 10 people have been arrested in the past two days.
Police have been monitoring the situation from the air.
The cost of sending police to the site was $910,000 from May 1 to July 20, Police Minister Liza Harvey told State Parliament yesterday.
The money, which did not include the regular wages of police officers, was spent on their accommodation, meals, overtime pay and travel to the site.
Supt Mick Sutherland, of Kimberley police district, called for an end to the protests, saying they were starting to have an impact on legitimate business operations.Willie Creek Pearls chief executive Tony Maio said the protest had severely hampered operations during Broome Cup week - one of the busiest weeks of the year for local tourism operators.
