The three councils are standing firm on their decision not to amalgamate despite the $13 million incentive from the state government in their Fit for the Future proposal.

Narromine Shire Council has backed itself as a stand-alone council since the amalgamation suggestions were released last year.

Mayor of Narromine, Bill McAnally believes merging the councils would have a negative impact on council services rather than saving money.

"I don't think there would be many savings, just look at the road systems, the amount of roads that would need servicing from one end to the other, there'd be problems," he said.

"We need our own shire."

Cr McAnally said the state government would have to give good reason for the councils to amalgamate.

"The State Government would have to come up with a pretty good story to get us to do it," he said.

Dubbo Deputy Mayor, Ben Shields is also concerned about the financial impact.

"What would happen if we were to say triple the size of our footprint and incorporate two very small shires of Wellington and Narromine into Orana Regional Council therefore burdening the Dubbo ratepayers with a massive extra road footprint that we'd have to undertake to maintain - would it not basically cause our ratepayers absolute financial hardship and indeed inevitably see massive rate rises like we've never seen before?" he said at a Works and Services Meeting in Dubbo on Monday.

Cr McAnally believes Narromine Shire has what it takes to survive as a stand-alone council.

"Narromine is strong financially, we're showing the government we're doing everything right," he said.

"We want to stand alone."

Cr McAnally said Fit for the Future was a good exercise for the council to go through.

"It made us look at our situation, it was terrific. Every council had to look at what it had to do," he said. "It was a learning curve for all of us, but we'll be able to stand alone."
