Livingstone Shire residents are being urged to carefully think about a vote that would see their area separate from the Rockhampton Regional Council.
Queensland local government minister David Crisafulli said such a move needs to be properly examined by residents, and realise how much it will cost.
The Boundaries Commissioner and Queensland Treasury Corporation (QTC) found that if the Livingstone Council were to come back to existence, it would cost an initial $9.9 million.
The news could affect people who own real estate in Rockhampton, with the minister confirming that shire residents would need to pay an extra $429 in annual rates.
The minister stated that the QTC also found there would be an additional $194 added every year after this and confirmed these figures are accurate and not estimates.
He commented: "QTC is totally independent, has no vested interests and has a vast amount of experience working with Queensland councils over many decades.
"While the report shows a new Livingstone Shire Council would have to increase rates, we believe locals should decide if that's worth getting their old council back."
There will be a referendum on March 9 – with only registered voters eligible to cast their opinion.
