Arrests 'not the only point' of Newcastle coal port blockade: Rising Tide

Climate change activists are trying to stop boats leaving the Newcastle coal port for 30 hours. File image.

A multi-day blockade at the world's largest coal port will be shortened if it goes ahead but police still expect civil disobedience if the planned protest proceeds.

Rising Tide organisers said the event from November 22 to 24 would be one of the world's most significant climate protests, involving demonstrators in canoes and kayaks blocking the Port of Newcastle.
