A Gladstone councillor says it could cost up to $80 million to repair flood-damaged infrastructure across the central Queensland region.
The council has closed Pikes Crossing Road at Benaraby near Gladstone for another month after discovering the road's foundations are unstable.
Property owners are allowing about 20 residents to use their land as a makeshift route to the Bruce Highway.
Cr Rick Hansen says the overall damage bill from this year's floods has not been finalised because there is still outstanding repair work from the 2011 flood.
"That took a long, long time to get contracts in place," he said.
"At that time, the Government didn't allow council to do any of the work - it had to be contracted out.
"We're still in those phases of finishing that work and now we're in the process of assessing the damage from this last event still.
"That's being done at the moment, so I think our director of engineering services estimated the damage could be anything from between $70 million to $80 million."
He says recovery after this year's floods will be quicker.
"Change of government, change of process, a little bit less red tape this time I think," he said.
"I believe that we'll be back on our feet a lot better and we'll have a lot better process of getting on with the job and getting it done.
"I'm confident it'll be a much shorter process this time around."
