Foley campaign focuses on NSW North Coast

Labor Leader Luke Foley continued his anti-coal seam gas assault on the NSW North Coast while Premier Mike Baird campaigned in Sydney's west.

With four days until the election Mr Foley headed to the North Coast for his second visit of the campaign, starting the day off at the spiritual home of the state's anti-CSG movement: the site of the Bentley Blockade in the Pilliga.

He is hoping to pick up Nationals held seats in Ballina, Lismore and Tweed off the back of strong anti-CSG and privatisation sentiments.

"Sink the Nats and that's the end of coal seam gas forever," Mr Foley told the 100-strong crowd.

"It won't take riot police, it will take the power of the ballot box."

Last year the site played host to a large protest against a proposed CSG mine, and the Baird government subsequently suspended CSG licences in the area.

But local residents say they are fearful CSG will make a comeback.

"The local member for the Nationals hasn't supported us in any way, whatsoever," one man told Mr Foley.

His North Coast trip came as former federal resources minister, and now mining consultant, Martin Ferguson accused Mr Foley of "rank opportunism" and "blatant scare-mongering" over his promise to keep the Pilliga Forest free from CSG, threatening a large Santos project in the area.

Mr Foley hit back, saying Mr Ferguson's views often departed from mainstream Labor policy.

Meanwhile, Mr Baird spent the day in Sydney's far west, campaigning in Liberal-held Penrith and Mulgoa.

Standing alongside Penrith NRL captain Peter Wallace, the premier pledged $12 million for the Western Sydney Community and Sports Centre which will provide space for netball, futsal and wheelchair rugby.

The premier had a kick with Penrith players and even managed to catch a bomb.

He was asked about union claims that the government was planning to sell off the state's electricity assets to the Chinese amid revelations that Treasurer Andrew Constance met with the State Grid Corporation of China - the largest state-owned electric utilities company in the world.

"This is just another desperate distraction from an opposition running the most negative scare campaign in the history of state politics," Mr Baird told reporters.

Mr Constance accused Labor and the unions of "dog whistle politics".
