The Isaac Regional Council says the damage bill to repair flood-hit roads is likely to be about $50 million.
The executive director of engineering and infrastructure, Andrew Macgregor, says the 2010 and 2011 wet seasons caused significant damage across the region.
He says tenders will be awarded in the coming weeks and council hopes to have work started before this wet season.
"We expect to get a couple of months in before Christmas and we are expected to have all the work from the 2010/2011 damage completed by June next year," he said.
"Typically the council spends $1-2 million on flood events, repairs a year.
"So far this program has been estimated in the order of $50 million as a result of those two very wet years.
"So that's a huge increase over what we're normally dealing with."
