Telstra says it hopes to replace flood-damaged transmitters near Gympie in south-east Queensland in the next few weeks.
Area general manager Kris Carver says temporary repairs have been made to reconnect hundreds of residents in the Kilkivan area but major repairs are still needed.
He says the repairs will begin as soon as the ground is dry enough for heavy trucks to access the area.
"As long as the weather stays dry, we'll be monitoring those and hoping to have permanent fixes done within the next couple of weeks but we are obviously at the mercy of the weather ... as long as it dries out we'll be out there fixing them ASAP," he said.
"We've done the temporary fixes and those have been done primarily around the Kilkivan area where we've had quite significant washouts around Wide Bay Creek.
"As the ground around it becomes well enough to get through and engineers give us the go-ahead and we can get our trucks in there, then we'll decide the best route - whether we rebore or go an aerial route - it will just depend on the situation."
