Gloucester shire residents together with a national lobby group are trying to stop any mining expansion in the area.
The Lock The Gate Alliance was formed late last year and already has more than 50-member groups.
One of the groups in the Alliance is the Barrington, Glocuester Stroud Preservation Society.
Its spokesman, Graeme Healy said mining does bring jobs and money to Gloucester, but the affects on the environment are more important.
“There are two operating coal mines here,” he said.
“One of them was scheduled to close in 2003 but it’s expanding rather than closing.
“In addition there’s a second company quite close to Gloucester township and there’s a proposal for a major coal seam gas development here.
“We’re on the brink of witnessing the industrialisation of this vale of Gloucester.”
Healy said the community is becoming increasingly concerned about mining exploration near Gloucester.
“Rural landholders have no security or certainty whatsoever.
“Suddenly a mining company comes in and says ‘well there’s something here that we’re interested in, we’ll explore and then down the track we’ll develop a mine.
“But the minute they put their hand up and say ‘we’re interested’, if people want to sell they can’t.
“Nobody’s interested in that property anymore because the threat of mining hangs over it, the value of the property declines,’ Healy said.
