Inspector-General Emergency Management Alistair Dawson has spent five months reviewing the response to the February-March floods in the state's southeast.
Mr Dawson will hand his final report to Police Minister Mark Ryan on Wednesday but it is not known when the document will be publicly released.
Mr Ryan said on Wednesday morning the government was yet to receive the report, however it was due by the end of the day and would be considered.
The inspector-general's office received over 240 submissions and conducted 13 community forums, with over 460 attendees.
As part of the probe, it reviewed the state and 23 local governments' preparations and responses to the disaster, triggered when parts of the region were hit by the most intense rainfall on record.
The inspector-general assessed the timing and effectiveness of public emergency alerts, measures to protect human lives and property, and the management of dams, in particular the Wivenhoe Dam.
It also assessed emergency service resourcing, the supply of essentials including food, water and electricity and cooperation between government and agencies.
"In conducting the review, the office will consider the views of community members, relevant agencies and operational staff and also be informed by any relevant expert advice," the terms of reference said.
The inspector-general's office said the report would identify possible improvements to Queensland's disaster management arrangements.
