The man in charge of Bundaberg's flood clean-up says four months after the disaster, a lot more still needs to be done.

There is concern about the resilience of the city's residents.

The January floods caused widespread devastation to six Queensland council areas.

The Bundaberg and the North Burnett regions were the hardest-hit.

Disaster relief coordinator Inspector Brett Pointing says while bridges and roads can be fixed, he is concerned about the mental health of affected residents.

"The forces of nature are incredible and for some people it won't be a matter of weeks or months but years," he said.

He says there is still a lot more to be done.

"While roads and bridges can be fixed quickly, clearly repairing people's lives will take longer," he said.

"We've seen the damage that has been done to primary industries, to farming and other areas of agriculture and these things will take longer."

Community recovery workers from Lifeline and the Red Cross are still employed in affected areas to help residents.
