Coffs Harbour Mayor Denise Knight says she is horrified at the prospect of Recreational Vehicles (RV's) and caravans taking over the Coffs Harbour Jetty Foreshores.
The proposal to let caravans and RV's park on council-owned land at the waterfront as approved by the council in February.
Details of how the new system will work have not yet been released.
Councillor Knight said she opposed the idea when it was debated in February, and she still believes it is a serious mistake.
"This is our pride, this is our jewel in our crown, and we're going to have RV's," she said.
"Now I've travelled in RV's, and don't tell me they spend a lot of money, they don't.
"They need to go into our proper caravan parks like everybody else."
The Mayor was one of four Councillors who voted against the motion, arguing it will damage one of the city's best assets.
Cr Knight said offering up the area for free is not fair to those who have to pay, elsewhere in town.
"Coffs Harbour likes to think that we are fair and equitable," she said.
"Being fair and equitable does not mean that some people get to park for free, use our water, wash their fry pans in our ocean, and other people are paying for a caravan park."
Meanwhile a Coffs Harbour councillor is defending his push to let RVs and caravans park at the Jetty Foreshores.
Cr John Arkan took the plan to the council.
He said if RVs cannot park at the waterfront they will bypass Coffs and the city will take an economic hit.
