The Inspector-General of Emergency Management recommends Queensland Fire and Emergency Services lead an inter-agency IT system assessment with Queensland Police Service and local governments to identify disaster management systems currently in use and develop options to enhance connectivity and interoperability between systems. Outputs to be considered include, but are not limited to, consideration of requests for assistance (RFA) and the production of situation reports.

The Inspector-General of Emergency Management recommends all local governments that offer an opt-in system develop strategies to increase the number of subscribers who elect to use this service. As part of the annual disaster management plan assessment process for the period 2023–2025, the Office of the Inspector-General of Emergency Management will request information from the relevant local disaster management groups to highlight and share innovative practices that have led to an increase in subscription levels for opt-in services.

The Inspector-General of Emergency Management recommends the Queensland Reconstruction Authority and the Bureau of Meteorology investigate options for the consolidation of ownership, renewed capital and maintenance in the flood warning network in consultation with flood warning infrastructure asset owners.  

Impact to essential services: That, to minimise disruption to essential services, including outages which compromise basic communication coverage, and to ensure access to safe water supply and power during flood events, Government work directly or together with the Australian and other state governments and/or their relevant power and telecommunications regulatory, policy and market bodies to:
• ensure there are sufficient redundancy options known and made available (for example, backup diesel generators, deployed temporary telecommunications facilities, etc.) to supply power to essential telecommunication infrastructure, alternative telecommunications infrastructure and water treatment facilities.
• ensure that the telecommunication entities, electricity network providers and water treatment managers are using up to the minute, whole of catchment models to inform business continuity planning in the event of flooding
• facilitate cross carrier roaming arrangements between carriers and the public for basic text, voice and data during the period of emergency in areas directly affected by flood
• ensure all essential services are mandatory members of the Emergency Management Committees at state, regional and local levels
• ensure the state understands essential services redundancies and what emergency redundancy options are available from Australian Government agencies
• ensure, given the heavy reliance on essential services by community and government during a disaster, essential services loss, redundancy and build back better principles are exercised through emergency management committee processes annually.

Risk-based approach to calculating flood planning: That, to take account of greater knowledge of climate change, Government reinforce its adoption of a risk-based approach to calculating the flood planning level for planning purposes and, through the NSWRA, immediately start a process of revising all flood planning level calculations in the state’s high-risk catchments. Flood planning level re-determinations for all high-risk catchments should be completed within 3 years. These revised flood planning levels will need to be factored into all development applications (in-progress and new) in those high-risk catchments. The risk profile of high-risk catchments should be revisited at appropriate time intervals to check that levels are current. A review should take place if there has been a significant trigger event (i.e. changed rainfall, development) or at least every 5 years. As well as reviewing the flood planning level, this 5-yearly review should include reviewing any floodplain lease conditions and adjusting them as necessary in the light of better knowledge of climate change impacts. In working out a tolerable, risk-based flood planning level, consideration should be given to the PMF, 1% AEP, 0.02% AEP, existing development, approved but not yet constructed developments, and existing and approved but not yet constructed evacuation routes.
In coordinating this flood planning level re-determination process, NSWRA should work closely with local councils, DPE, communities, state water authorities and state and national engineering and research organisations. In doing so, the NSWRA should also:
• extend and then maintain the DPE state-wide flood database and associated visualisation interface. This database, which should link to LandiQ, would support:
— monitoring of the flood warning and sensing environment
— monitoring of trends in rainfall activity and impacts, including timing, cause, extent and intensity
— tracking trends and identifying patterns in associated weather and climate signals that contribute to severe floods
— evaluation of the cost and effectiveness of risk mitigation efforts, including land preparation, planning use and management, to enable a better understanding of what works
— simulation of extreme rainfall events and resultant flooding
— identification of ‘at risk’ river and catchment systems for flash flooding
— rapid and effective deployment of resources during a flash flood event
• act as the main coordination point for all NSW hydrological modelling, working with local government, other state agencies, universities, professional bodies (e.g. Engineers Australia) and the Australian Government (especially the Bureau of Meteorology and CSIRO) to improve future NSW flood risk assessment (and hence accuracy and timeliness of flood prediction) by building more formal connections between the extensive existing physical hydrological modelling (done by various NSW agencies) with the Bureau’s meteorological and climatological research and riverine flood models
• support local councils to improve modelling of and ensure adequate and appropriate alarm systems for flash flooding.

Essential services and floodplain infrastructure: That, to minimise disruption to essential services (power, communications, water, sewerage) and to ensure flood infrastructure is fully serviceable before flooding, Government ensure:
• essential services infrastructure (communications, water, power and sewerage) is situated as much as possible above the flood planning level. And to minimise disruption to medical services, aged care services and the police, Government ensure hospitals, medical centres, nursing homes, aged care facilities and police stations are situated above the probable maximum flood level
• floodplain infrastructure (drains, levees, flood gates) items are all assigned to an appropriate lead agency which has responsibility for ensuring they are fully maintained and functioning especially when floods are likely.

Cost benefit framework:That, to enable a more systematic prioritisation of investment options in risk mitigation before, during and immediately following a natural disaster event, Government adopt and utilise a Disaster Cost Benefit Framework. This Framework will enable Government to estimate the investment required for any given disaster, starting with flood events, and will enable the fast allocation of funding based on detailed and rapid analysis of flood and property modification, mitigation, preparation, response and finance related options including:
• flood modification measures/flood defence (including dams/ water management; levees; waterway or floodplain modifications; etc)
• property modification measures/flood risk mitigation (including land filling; flood proofing; house raising; optimum zoning; removal of development (buy back schemes/relocation))
• response modification measures/flood preparation (including flood warnings; upgrading evacuation routes; evacuation planning; emergency response and education programs; flood data collection and sharing; etc)
• finance related options (including building standard reforms; restructure and reduction of stamp duty; direct subsidies; government reinsurance pools; etc)
The Framework should build on the preliminary version developed by NSW Treasury and provided to this Inquiry. To support this Framework, Government should also use the NSW Adaptation Fund that can be drawn on during or immediately following a flood event.

That the NSW Government advocate through the National Cabinet for the Bureau of Meteorology to review its rain data infrastructure and flood modelling tools, to ensure forecasting locations, rain and flood gauges and other infrastructure are appropriately placed, maintained and updated.

That the NSW Government work with relevant agencies and local landowners to find ways to improve the management of drainage channels including looking for recommendations to reduce red and green tape. 

That the NSW Government significantly increase its investment in flood mitigation and preparation, including its support of local governments to do the same, by: • increasing ongoing, long term funding and access to technical guidance and assistance for local councils • ensuring that land-use planning and development takes a risk-based approach. 

That the NSW Government prioritise support for the full restoration of sewage treatment facilities on the Richmond River, for the benefit of communities in the Northern Rivers region. 

That the NSW Government, in consultation with telecommunication providers and satellite communication providers, investigate ways to minimise the complete loss of telecommunication services in natural disasters, including:
• the distribution of satellite phones and satellite terminals to community hubs in flood prone areas
• the prioritisation of services for communities that are highly likely to become isolated in a natural disaster
• the establishment of appropriate protocols to ensure that this equipment is readily available and 'charged' for use with a battery supply.

To ensure enhanced capability integration and enable timely community messaging Bundaberg LDMG in consultation with Sunwater develop additional Emergency Alerts and associated polygons for a Paradise Dam failure and load these on to the disaster management portal. 

To enhance shared capacity and collaboratively manage risk, the Chair of the Bundaberg DDMG use the QERMF process to determine if dam failure for Paradise Dam should be reported as a residual risk in this instance due to known changes in the risk profile to:
- the State Disaster Coordination Group (SDCG) in accordance with their responsibilities under the State Plan
- QFES for ensuring the development of the state-wide risk assessment. 

To increase shared understanding of risks, ensure the coordination of plans and manage risks, dam failure for Paradise Dam be included as a separate risk within the Bundaberg District Disaster Management Plan (DDMP). 

To increase understanding of hazards and manage risks, dam failure for Paradise Dam be included as a separate risk within the North Burnett Local Disaster Management Plan (LDMP). 

To enable entities to have a shared understanding of forecast information for dam failure events during a flood, including flood wave travel time, speed and height, Emergency Action Plans contain protocols and responsibilities of relevant stakeholders for these aspects. 

A strategy should be developed to improve the availability of information to decision-makers and other audiences. Information should be searchable, more specific, timely, and allow stake-holders to find what they want.

Planning and warnings for storm tide should be based on modelling that shows the chances of an event occurring (probabilistic).

Queensland should examine the feasibility of the installation of storm tide markers in prominent public places and the exploration of new technology to highlight storm tide risk to the community and its visitors. 

The operation and maintenance of flood gauges should be developed and planned for on a catchment basis.

A revised Victoria Flood Management Strategy should identify and assign roles and responsibilities for the management and ongoing maintenance of Victoria’s waterways, for the purposes of flood protection and flood mitigation:
• CMAs are confirmed as the responsible authority for the management and ongoing maintenance of waterways, including vegetation management, for the purposes of flood protection; and
• CMAs will negotiate with landholders, councils and other authorities, and conduct agreed flood mitigation works on the basis of beneficiary pays.

Regulators can help to achieve improved outcomes by considering the issues identified by this review

Fire services can improve outcomes by initiating discussions with landfill operators about fire management planning and emphasising the critical importance of water supplies and early intervention

As part of the current revision of its contract template for sponsorship agreements, Tourism WA should ensure that:
- Risk management plans are submitted for approval with all relevant agencies and local and state authorities no later than two months prior to a sponsored event being staged.
- Milestone payments should be linked to the strict adherence of this deadline 
- Evidence of approval of the risk management plans by all relevant local and state authorities is provided to Tourism WA by the event organiser.

the state ensure that any new systems and equipment purchased by state emergency management agencies are interoperable with other relevant agencies to the fullest extent possible. This should involve the state establishing a procurement gateway process with input from the Emergency Services Commissioner.

the state take the necessary measures to upgrade existing manual stream and rain gauges and ensure that all future gauges provide a seamless transfer of data from the gauges to the Bureau of Meteorology.

That the Tasmania Fire Service consider improvements in radio units installed in breathing apparatus:
(a) It is recommended that investigations, which the Tasmania Fire Service already initiated, continue as to alternative radio units to be installed into breathing apparatus but until a suitable replacement unit is found that specific training be given to fire fighters not to rely solely upon breathing apparatus radios for communication. Specific training should be directed at fire fighters to assist them in emergency situations when breathing apparatus communications fail.

That agencies assess the cost-effectiveness of establishing a dedicated and proven asset management information system which is integrated with the other information systems used to manage drainage assets.
