When the gas industry tried to stake a claim on small New South Wales community in 2010, the locals fought back. Rallies began, culminating in a blockade in the farming valley of Bentley where protesters faced riot police. It ended when the government stepped in - putting a halt on gas-fields in the area. A filmmaker decided his contribution to the movement would be to document the struggles, over six years. It's now been made into a feature-length documentary called "the Bentley Effect".
