Warrnambool City Council says unruly public gallery members at meetings could be hit with $825 fines.
Chief executive officer Peter Schneider said the council could slap disruptive people with the hefty fee.
"Those failing to comply with a direction from the chair risk a fine of five penalty units - about $825," he said.
"A council meeting is similar to meetings or sittings of other levels of government where the public is invited to observe but not participate in the debate between democratically elected representatives."
His comments come after Monday's meeting was adjourned for a period of time after some members of the gallery expressed their anger about sending the chief, mayor and a council officer to Sweden.
Some councillors left the chamber while mayor Tony Herbert asked objectors to refrain from shouting.
Mr Schneider requested people in the public gallery not to interject.
"Council asks that people at council meetings behave respectfully," he said.
"Our Local Law states that visitors must not interject or take part in the debate. Members of the gallery must accept direction from the chair of the meeting."
On Tuesday Cr Herbert said some members of the gallery were "abusive and aggressive" while Cr Mike Neoh said they had a "mob mentality and neanderthal-type behaviour".
