Wagga City Council could potentially spend tens of thousands of dollars in an attempt to crackdown on councillors leaking confidential information.
Councillor Tim Koschel aired his frustrations at Monday night's meeting, calling for a review of the council's current policy of confidential information and the introduction of an independent investigation.
He said the matter was hard to address, but councillors needed to be called out for this behaviour and held accountable for their actions.
General manager Peter Thompson said the cost of an external investigation would be expensive and the councillors need to discuss what they hoped it will achieve.

"I have undertaken an external investigation previously and the scope of work cost $30,000, but it is heavily dependent on the scope of work," he said.
"If you want to be chasing wrong-doers for disclosing confidential information, I am not sure what the benefit of that would be."
Mr Thompson suggested a report looking into why people are disclosing confidential information and encouraging a better approach could be more effective.
A report will return to council that reviews the management of confidential information held by councillors and staff.
