PUBLIC outrage about coal seam gas mining has pressured political parties to make their positions clear ahead of the September 14 federal election, Greens MP Jeremy Buckingham said.
Mr Buckingham attended last Wednesday's protest to represent his party's views during Premier Barry O'Farrell's visit to Liverpool.
He said the NSW Greens would take the mining issue matter to state and federal parliaments, and push for a moratorium and a residential ban.
"The people of western Sydney are here to tell Barry O'Farrell that they don't want coal seam gas mining, that it's unsafe, unwanted and unnecessary," Mr Buckingham said.
"People are very concerned of the health impacts from an industry that has proven to increase asthma in children in the US, lead to respiratory illnesses, increases in cancer and other such ailments.
"This industry has not proven safe."
Mr Buckingham said NSW Health expressed concern it had not been asked to give a submission to the proposed Camden gas expansion.
"That rings an alarm bell for the community, when the department of health is not being asked their view, and their view is that this industry is a threat to human health," he said.
