The party contested its first election in 2013 and five years later its first MP was elected in Victoria.

Mr Bourke said Sustainable Australia was not linked to big business or big unions but was linked to the community.

"We present issues from the common sense political centre," he said.

"We are standing on the big issues that matter to people's daily lives like a sustainable environment, like affordable housing, like secure jobs."

Mr Bourke said the big issue for the party in the NSW election was better planning to stop overdevelopment.

Other priorities are a sustainable environment and population, affordable housing for first home buyers and renters and secure jobs through a more diverse economy.

Lake Cathie resident and candidate for the seat of Port Macquarie Jan Burgess is among 55 Sustainable Australia candidates contesting lower house seats, while 21 Sustainable Australia candidates are running for the upper house in the state election.

The party will also have candidates in the federal election and next local government elections.

Mr Bourke and Ms Burgess were on the campaign trail in Port Macquarie on Tuesday, March 12.

"This is such an important regional city in NSW," Mr Bourke said.

"We need to put the pressure on the major parties to make sure we have better planning and to make sure they deliver the services that regional Australia needs."

Mr Bourke is on the road touring NSW in the party's voter van, Winnie the Winnebago, ahead of the March 23 poll.
