The Shooters, Fisher and Farmers Party (SFFP) is vowing to introduce legislation next year to block council mergers in New South Wales.

The party will draft the laws which will also give affected communities a chance to have their say on whether they support their amalgamation.

Shooters MP Robert Borsak said the details of the legislation were yet to be determined but he said the party was confident it would pass the Upper House.

"I think we can get a lot of support," he said.

"The ALP have voiced their opposition to the mergers, as have the Greens, and Fred Nile has always been against the merger proposals.

"I am confident the bill will pass the Upper House.

"I call on the National Party to cross the floor and support their local communities that are not happy with these deals.

"The residents in Cabonne, Oberon, Guyra and a host of other council areas are worried about self-determination, loss of local jobs, maintenance of roads and bridges and other vital infrastructure."
