ALP pledges CSG-free zone in northern NSW

NSW Labor has vowed to make the state's north coast a coal seam gas (CSG) free zone.

Delegates at the party's state Labor conference backed the motion on Sunday which affects Lismore, Ballina, Clarence and Tweed electorates.

Under a state Labor government, the CSG industry will be banned from the NSW north coast and the Northern Rivers region.

Former federal Labor MP Janelle Saffin told the conference, held in Sydney's Town Hall, that the motion aligned the party's platform with community opposition to CSG mining.

The motion comes after the NSW government in May suspended Metgasco's drilling licence in Bentley, in the state's Northern Rivers region.

The suspension came just days before thousands of protesters were expected to form a blockade at the drill site and up to 800 police officers were detailed to monitor their activities.

Metgasco has filed for a judicial review in the Supreme Court.
