Pre-poll voting opens today for the four Queensland communities short-listed for potential de-amalgamation.
Electoral Commission Queensland (ECQ) says almost 80,000 residents in the former Mareeba, Douglas, Noosa and Livingstone shires will take part in the compulsory ballot.
Local Government Minister David Crisafulli says it is compulsory for residents to vote or they will get fined.
"I want people to do two things - the first is to know that voting is compulsory - that they have to - otherwise there'll be a $110 fine," he said.
"The second is to make themselves available of that information to make an informed decision."
Mr Crisafulli says voters can access pre-polling stations from today.
"The reason why I'm so adamant that it's important people vote is we want to get a big turnout, because we want to know what the community thinks," he said.
"There's a lot of strong views on both sides of this argument.
"It's important that the everyday man is also heard.
"If we get a good voter turnout, that will clearly show that whatever the result is there is clearly a mandate."
ECQ assistant commissioner Walter van de Merwe says up to 40 per cent of residents are expected to vote ahead of the poll on March 9.
"Electors will receive within the next few days a voter information letter personally addressed to them," he said.
"On that letter it'll have information of polling booths, postal voting, pre-poll venues and the like."
