Councillors voted to request a report from the chief executive within two months outlining how non-confidential records of briefing meetings could be safely published on the council's website.
The report will examine what information is already recorded, what could be made public, how confidential information would be protected and how other councils manage similar processes.
Moving the motion, Cr Adrian Weston said the proposal was about continuous improvement in governance rather than addressing a problem.
"This isn't a motion to fix the problem; it's a motion of continuous improvement," he said.
Cr Weston said councillor briefings were a vital part of the decision-making process, allowing councillors to receive detailed information from officers and ask questions before matters came before council meetings.
"Briefing sessions are a critical component of councils being able to ensure that they inform themselves to the extent possible to make good decisions in the chamber," he said.
Under the proposal, any published records would be limited to governance information such as councillor attendance, agenda items discussed and declarations of conflicts of interest.
Confidential, commercially sensitive and legally protected information would not be disclosed.
Before the motion was adopted, Cr Paul Jarman successfully sought the removal of a reference to publishing "presentations received", saying he was concerned it could discourage open discussion during briefings.
Cr Weston accepted the amendment, and seconder Cr Zoe Cook supported the change.
Cr Cook said publishing a summary of briefing meetings would provide reassurance to the community that councillors were attending briefings and appropriately declaring conflicts of interest.
"I think having a document for the public to be assured that the councillors are being transparent and following those conflicts of interest protocols throughout is very important," she said.
Several councillors said the proposal struck an appropriate balance between greater transparency and maintaining confidentiality where required.
Cr Tony Marwood said it was important that any future system clearly defined what information should remain confidential, so councillors could continue to have robust discussions before formal decisions were made.
Mayor Daniel Mackrell said Campaspe already had a strong record on transparency, with the proposal representing another step forward.
"We are a very transparent organisation," he said.
"What I do see here is all about transparency."
The chief executive's report is expected to be presented to council within two months before any decision is made on implementing the publication of briefing records.
