The investigation centres on allegations of bullying and harassment.

A WorkSafe spokesman today confirmed the investigation is ongoing.

WorkSafe inquiries are continuing," he said in reply to inquiries about the state of the probe.

The same spokesman said on February 20 his organisation would not comment while the investigation was being carried out.

The death of the council worker happened late last year.

At that time police also investigated the same incident but a Warrnambool police spokesman said no action was being taken.

WorkSafe was also contacted at that time but had not initiated an investigation.

In mid February further information was provided to the regulator which sparked inquiries.

It was understood at that time council officers were in the process of being interviewed.

There has been no time frame set for when the investigation is expected to be completed.

Back then Warrnambool City Council chief executive officer Peter Schneider said the health and well being of staff was paramount to the council.

"Council would always co-operate with WorkSafe on any investigation and is committed to providing any information WorkSafe requires," he said.

Confirmation of the investigation comes after two long-time councillors raised issues about a "toxicity" and "serious culture issues" within the council.

Neither gave specific examples.

Long-time former councillor Peter Hulin spectacularly resigned from the council about the same time, saying he could no longer work with his fellow councillors and an organisation that he said wasn't "open or transparent".

He said there was bullying within the council and "regular reports of toxicity in the workplace".

"That is not acceptable to me," he said.

That was followed by another long-term councillor, Mike Neoh, saying he was prepared to be sacked for speaking out about cultural and communication issues at the council.

Cr Neoh said he had plenty of concerns about council processes over the past 12 months.

He said he believed there were "serious cultural issues" within the organisation.

"I welcome any investigation on serious matters regardless of the issues," he said.

In relation to cultural issues, Mayor Tony Herbert said there were "a number" of investigations under way at the council to "weed out the individuals that are acting negatively towards other members of staff".
