The shire sent letters to the Governor, the Ombudsman and Local Government Minister Richard Wynne calling for an inquiry into the way Warrnambool City Council conducted the expressions of interest process during two attempted sales of industrial land owned by the two councils.

The request for an inquiry was declined and the shire was instead advised to take the matter to the Victorian Civil and Administrative Tribunal.

But at this week's Moyne council meeting, councillors decided to send one final letter to the minister.

Councillors Jill Parker, Ken Gale, Mick Wolfe and Colin Ryan voted in favour of the motion to send the minister a letter explaining the shire did not believe VCAT was the appropriate authority to deal with the matter as their main concern was about the process undertaken by Warrnambool City Council during the attempted sale.

The councillors said they believed the minister may have misunderstood the purpose of the letter but agreed this should be the final attempt at pursuing the matter.

"I was very disappointed when we received the letter," Cr Ryan said.

"I think (the minister) missed the point of what we were trying to achieve as a council.

"It would help the whole situation if the minister conducted an investigation."

Councillors Jim Doukas, Bernie Harris and James Purcell voted against the motion.

"I don't know what would be achieved," Cr Purcell said of one final letter to the minister.

"I think it's time to accept it and move on and get on with business."

Moyne disagrees with Warrnambool City Council's decision to have a third attempt at selling the land both councils bought in 2003 for a planned industrial park, which was later abandoned when an engineering report found the land was riddled with sinkholes.

At both attempts to sell the land only one interested party has lodged an expression of interest.
