Two Dubbo Regional councillors say they've "lost confidence" in mayor Ben Shields, calling for him to resign.
Deputy mayor Stephen Lawrence and councillor John Ryan said the mayor had endangered public confidence in public processes, and called for him to "do the right thing and resign".
"Its been a gradual process, and you can't look at any one incident in isolation," Cr Lawrence told the Daily Liberal.
"I know that councillor Ryan shares that view, I won't speak for anyone else but that's our strong view."
The call came after the mayor held a press conference in January with the developer of the former RAAF base in Dubbo, about major retailer Bunnings moving to the site.
Cr Lawrence said the multi-million dollar Bunnings redevelopment is yet to be approved by the council, and this announcement had undermined public confidence.
"The community cares about the old RAAF base, the community cares about housing supply issues in Dubbo, and too many people have come to me and said they think that Bunnings on the RAAF base is a done deal, it's not a done deal," he said.
"It will certainly be my intention going forward to look closely at the question whether that DA needs to be dealt with in some way by the state government or a delegate."
The councillors have also expressed concern in the mayor's approach to the redevelopment of the Regand Park site in Dubbo.
"At the second last council meeting we were given half an hour notice of a mayoral minute proposing that council give in principal support to 10 hectares of public land to a private interest," Cr Lawrence said.
"I said at the time that I thought it was simply appalling."
"A key aspect of local government is consultation, local government is a level of government that is closest to the community, its a level of government that has the capacity to consult with the community, and the expectation, and indeed its in legislation, is that we do consult about important matters."
Cr Lawrence said it was his view that the only way to "undo the damage" that had been done to public confidence, was for the mayor to step down from the role.
"I can't understate how important it is that councillors act in a way to ensure public confidence in development application processes," he said.
"There is nothing that undermines councils and local government more than perception in the community that such processes are not fair and transparent.
"Ben has shown, in my view, a disregard for proper process, he has endangered public confidence in council, and as far as I'm concerned he needs to resign."
The call for the mayor to resign was backed by Cr Ryan who said he believed "everything is broken" and the council needed a "reset".
"The mayor is a bloke who loves Dubbo and he's done a lot of good things for Dubbo, but you cannot make decisions by yourself, you need to bring the councillors and the community along, you need a consensus," Cr Ryan told ABC Western Plains .
"I think everything is broken and we need to have a reset."
Cr Lawrence said he would be meeting with the mayor on Monday afternoon, and said the "ball is in his court".
"It will be a matter for him what he does. We have no legal power to remove him," he said.
The Daily Liberal contacted Cr Shields, but he declined to comment.
