Brisbane City Council expects the last of its eight flood-damaged ferry terminals to remain closed until December, citing material and worker shortages for the delay.
The council's transport committee chairman Ryan Murphy said North Quay and the Regatta terminals would take the longest to repair after sustaining the most damage during February's floods.
He said Holman St, Sydney St, Maritime Museum, QUT Gardens Point, UQ and Milton terminals would start "coming online from October".
Most of the damaged terminals were reopening in May.
At the time, Mr Murphy said the Milton and Regatta terminals would not open until at least October but would not give a specific timeline for the others.
"It's very likely we will be able to have all eight terminals open before Christmas," Mr Murphy said.
"We are working as hard as we can to get the repairs completed.
"Unfortunately we are seeing some acute material shortages and availability with our contractors.
"There are no major structural issues, just a real laundry list of repairs that need to happen to them."
Mr Murphy said most of the ferry terminals required silt removal from gangways, repairs to external panels and the replacement of flood-damaged anodes, roofing, fencing and glass balustrades.
There were still some repairs occurring at the West End ferry terminal, but it was in daily operation.
The Thornton Street terminal was partially demolished in order to replace river-based elements such as the gangway and piles.
Mr Murphy said money for that project would be "recovered through insurance processes".
He said the delay in reopening would not create any extra costs on top of the $20 million ferry terminal repair bill.
Fitzgerald Construction was working with council to get the terminals running again.
