Dozens of protestors remain camped out at Fullerton Cove despite police attempts to end their blockade.
The number of protestors swelled to more than 70 yesterday, with officers issuing 5 infringement notices to people who blocked access to DART Energy's coal seam gas pilot project.
Fullerton Cove residents, Lisa McDonald and Julie Wood have chained themselves to a tractor.
The NSW Greens say the police response is an over-reaction to what is a peaceful protest.
Dart Energy has received state and federal approval to drill four test holes. NSW Energy Minister Chris Hartcher says the company's application had been subjected to rigorous scrutiny by various governmment agencies and the project was found to be environmentally safe.
The blockade at the site is now in it's 4th day.
