Southeast Queensland's devastating floods have killed a dozen people, and authorities believe the disaster will cost the state more than $2.5 billion.
The death toll rose to 12 when a man's body was found after his car was swept into floodwaters in the South Burnett Region on Sunday. Another man is still missing.
Queensland Treasurer Cameron Dick said the floods, which have been going for two weeks but peaked last weekend, will cost the state at least $2.5 billion.
