The Floods Inquiry has questioned the accuracy of a model used to determine a property’s flood risk in south east Queensland.

The Commission has heard terms used to describe a property’s flood risk – like Q100 – can mislead and confuse the public.

The Inquiry’s previously heard evidence from Brisbane residents whose homes were built above the Q100 flood height – but were inundated anyway.

Counsel Assisting the Commission Peter Callaghan told today’s hearing it might be time to “move away form the Q100 mentality”.

The Inquiry has commissioned eight hydrology experts to examine the matter.

Today’s sitting includes a panel discussion with the eight engineers.

They have concluded the Q100 flood model should be abandoned in Brisbane until a new flood study is completed.

That could take three years.
