Dozens of farming families near Gunnedah, NSW, are continuing a blockade today to stop BHP Billiton drilling to look for coal.
Tim Duddy, a sixth-generation farmer at Caroona, raised the stakes in a 12-month dispute last Friday when he parked a grader across the driveway to his property.
He was served with a court order that forced him to let the surveyors in, but friends and neighbours arrived and blocked the road with vehicles.
The protesters have settled in, with some spending a cold night beside campfires along the driveway.
BHP Billiton plans to drill about 300 bore holes - a few centimetres wide but hundreds of metres deep - across the district.
"This is beautiful farming land and we don't think it should be part of another coal mine," Mr Duddy said last night.
The mining company is about two years into a five-year exploration project and has received permission from other landholders to drill test holes.
"We need to be sensitive; this is a process that takes a long period of time," said Stephen David, the managing director of the Caroona Coal Project.
A court hearing in Gunnedah will assess Mr Duddy's case on July 31.
