Queensland flood actions would be different in hindsight - Water Minister Stephen Robertson

"I have instructed my department to make this issue their top priority," he said in a statement.

Mr Robertson also said the Government would legislate to "ensure there is greater clarity and understanding about whose role it is to undertake certain actions in relation to our dams in times of heavy rainfall."

It comes after the report found there was confusion in the lead up to the flood about whose responsibility it was to provide advice on releasing water from the Dam.

It found Mr Robertson had failed to resolve that confusion.

"We wanted frank and fearless advice and we will not back away from these findings," his statement said.

"The State Government will be in a much stronger position going into the next wet season."

The Courier-Mail revealed on Saturday an email trail which highlighted the state of ill-preparedness in the government in the months before the floods and after extraordinary warnings were given to State Cabinet about the looming wet season.
