NSW deputy premier Troy Grant has called for an end to CSG mining in northern NSW.
The Nationals leader said March state election results, in which the Greens took the seat of Ballina, had influenced the call for new policy.
"I support the views of regional communities and it has been made very clear that the Northern Rivers community does not want CSG," Grant said.
"Through the NSW Government's gas plan, CSG licenses in the region are being bought back or cancelled.”
The proposition includes the buyback of seven Northern Rivers mining licenses.
Grant is expected to bring the matter up at the National Party Conference in the Hunter Valley today, with a ban on CSG mining expected to go up for debate.
Premier Mike Baird has not said if he will support such a move, and would not say if Grant had lobbied him to support a complete ban, Guardian reported.
