The Queensland floods inquiry has ended its first round of public hearings.
The commission is examining what caused the disaster and how emergency services can better respond in future floods.
Brisbane and more than 80 towns were hit by the floods that covered an area larger than the size of France and Germany combined.
The inquiry has held seven weeks of hearings and has more than 6 million pages of material to process and analyse.
The ABC reports the deadline for handing down the final report has been extended and is now due in February next year.
The inquiry's interim report is due on 1 August this year.
Hearings have been held in Brisbane, Toowoomba, Goondiwindi, Rockhampton, Emerald, St George and Dalby.
The ABC reports that round two of the hearings will consider land use planning and the performance of private insurance companies.
Submissions on insurers were due in April but the deadline has been extended until 15 June.
