As part of its review of the Energy Retail Code of Practice, the ESC should include requirements for energy retailers to collect the phone and email contact details of customers and others in the household for the purpose of sharing with distributors to facilitate information about power outages. Retailers should be required to check data quality and share with distribution businesses regularly.

The committee recommends that the Australian Climate Service and the National Emergency Management Agency work with all levels of government and industry to establish and maintain a national disaster risk map and database, covering all types of natural disasters in Australia, which is accessible to the public.

That Melbourne Water and other floodplain management authorities review flood models every five years and update the models at least every 10 years and after the occurrence of a major flood.

That the Victorian Government ensure that future flood mitigation efforts include updated and rigorous hydraulic modelling before implementation, ensuring the effectiveness of compensatory measures. Additionally, these strategies should undergo independent peer review to validate their expected performance.

That the Victorian Government fund floodplain managers to develop maps modelling scenarios demonstrating the impact on landholders of specified levee breeches.

That the Victorian Government work with floodplain management authorities and climate scientists to understand how flood modelling can be used to better predict the impact of climate change on flooding and update its flood management policies in line with this understanding.

That the Victorian Government provide Victorians with access to appropriate data contained within the FloodZoom platform

That the National Climate Service 5.2 establish a portal for climate information, products and services sourced from across a range of quality assured providers that:
5.2.1. gradually builds over time a library of open-source climate information products and services
5.2.2. provides publicly available, up-to-date climate information for Australia (including states and territory regions and coastal zones, Australia’s oceanic Exclusive Economic Zone and external territories)
5.2.3. presents information in easy-to-understand ways with a variety of formats for download and visualisation
5.2.4. includes external, reputable information from up-to-date sources domestically and around the world, including from other national and transnational climate services.

That the National Climate Service develop robust quality assurance processes for data, tools, information and services provided by the National Climate Service and made available on the climate information portal.

That the National Climate Service conduct a gap analysis of Australia’s climate data and information needs and user literacy and refresh this regularly.

That the National Climate Service promote data standards to integrate and connect data from different fields, aligned with international best practice.

That the Australian Government require, and fund as necessary, the responsible agencies to uplift natural hazard data inputs to a level required by the National Climate Service and the National Emergency Management Agency, with co-ordination of data for emergency management (e.g. hazard extent mapping, forecasting and tracking of historical events) to be managed by National Emergency Management Agency and hazard projections to be co-ordinated by the National Climate Service.

That the Australian Government require the National Emergency Management Agency make its data and products opensource and accessible to government and the public wherever possible.

That the Australian Government signal to partners and suppliers that the National Climate Service is open to collaborating and data sharing

That the Australian Government require all publicly funded climate models to be published on the National Computing Infrastructure with minimal restrictions, to encourage wide reuse and scientific scrutiny.

That the National Climate Service Improve access and usability of climate information by making Commonwealth-funded products free and open-source by default.

That the Australian Government establish an appropriate data solution (e.g. a data platform) to publish climate and hazard data; enable federated data curation including for domain data; support access for a broad range of data providers and public; create data insights and publish information as needed.

That the National Climate Service establish and grow a knowledge brokering service that assists users to find the data, information and advice needed to resolve their climate questions and understand the uncertainty inherent in climate models.

That the Australian Government develop a long-term national strategy and funding approach for computational infrastructure and data storage for climate data and modelling.

The Committee recommends that the Australian Government work with state and territory governments to ensure flood maps are produced to a high standard across the nation, regardless of the size of the local government area producing the modelling. This may require:
- increased funding for local government areas and water authorities, and
- the development of agreed standards to ensure that flood mapping is completed to at least an agreed minimum standard.
That, over time, this higher quality flood modelling be made freely accessible to homeowners and the general public along with easy to understand information about flood risk exposures at each property. This may be best undertaken in the first instance by local councils and/or water authorities responsible for generating the flood modelling, consistent with Recommendation 3 of the Actuaries Institute’s Funding for Flood Costs report (August 2023).

The Committee recommends the Australian Securities and Investments Commission consider seeking data from insurers on their performance based on the metrics recommended in Recommendation 51:
- Quarterly, for business-as-usual operations
- Monthly, for each declared event.

The Committee recommends that the Australian Securities and Investments Commission and the General Insurance Code Governance Committee share data so that it is possible to evaluate breaches of the General Insurance Code of Practice in the context of an insurers’ overall claims profile.

The Committee recommends the Australian Government and Insurance Council of Australia explore measures to facilitate the exchange of substantiated information about the resilience of a property to insurers, including new mitigation measures undertaken through state-based grant and loan programs.

The Committee recommends that the General Insurance Code Governance Committee publish aggregate data on code breaches by clause, individual insurer, and brand.

The Committee recommends that the Australian Government continue to work with the insurance industry through the Hazards Insurance Partnership to collate:
- data contained in the National Flood Information Database, and
- household-level data held by insurers (de-identified where appropriate).

The Committee recommends that the Australian Government ultimately move towards a national, centralised, public-facing portal containing flood risk data at the household level for:
- all households and small businesses across Australia, and
- all land being considered for release for development and all land that has been released for development, but not yet developed.
Agencies tasked with developing the portal should reflect upon governments’ past efforts to develop similar portals and lessons learnt. The portal should be easily accessible, user friendly and display high-quality flood risk information in a way that is readily understandable to communities. That before data is released on such a portal for existing properties (residential and small business), that the entity creating the flood study release that data through a staged process involving appropriate community consultation and engagement.

The Commonwealth should prioritise its data coordination efforts, including the provision of timely decision relevant information to assist decision makers to manage their risks and satisfy their disaster management objectives.
- Relevant data includes disaster risk information, climate hazard impact, capability and capacity information and vulnerability data.
-The data provided should be in a format that is usable by decision makers across all levels of government.

The Committee recommends that the Australian Government work with state, territory and local governments and road agencies, including Austroads and the National Transport Research Organisation, to address existing road asset data gaps by developing a comprehensive understanding of the road network condition and standardised road asset dataset, with agreement on the following:
- a common definition of road asset data
- a consistent format across road asset data collection and storage.

For future emergency response programs, the Department of Climate Change, Energy, the Environment and Water develop requirements for service provider reporting that enables output and outcome data to be compared or aggregated to provide assessment of progress at the program level.

Melbourne Water should commission an independent expert review and audit of their forecasting system with the aim of identifying areas where forecast accuracy, warning times and model run times could be improved.

Melbourne Water should use the hydraulic model being developed (expected to become available in April 2024) to determine (and be subjected to independent peer review) the impact of the Flemington Floodwall and the efficacy of the associated downstream compensatory works.

Melbourne Water should adopt forecasting tools which enable forecasts to be made within a total of no more than 60 minutes.

Melbourne Water should ensure that their rating curves, which represent the relationships between river levels and corresponding river flows, extend also to rare and extreme flood events and have been derived using established bestpractice.

Melbourne Water should have a protocol that enables flood forecasting at intervals at less than two hours when prudent to do so by reason of the responsiveness of the catchment for significant events.

Melbourne Water needs to ensure that rainfall runoff and flood models are calibrated to observed flood information.

Melbourne Water should immediately update the Mid Maribyrnong flood model with a modern two dimensional flood model developed in accordance with Melbourne Water guidelines and use this model to set new design flood levels.

Melbourne Water should review their flood models every five years and update them at least every 10 years and after the occurrence of a major flood.

We recommend that DELWP enhances bushfire modelling by: - exploring multiple bushfire modelling tools to lower the uncertainty and limitations associated with using a single modelling tool - applying more detailed fire-severity data - validating and updating fuel accumulation curves - establishing and regularly updating an archive of well-documented fire events and using this to systematically test it against a broad range of burning and fuel conditions - establishing and implementing processes to routinely review and update its underlying datasets.

The Inspector-General for Emergency Management recommends that Emergency Management Victoria – in consultation with relevant agencies – develop a system to manage personnel and asset deployments to all tiers of incident management to meet the needs of the emergency and support the health and wellbeing of personnel. Where appropriate and within occupational health and safety requirements, this may include:
a) standardised shift rosters across agencies and incident management tiers
b) a single or integrated platform to allow consistent recording of shift times and locations
c) records of accreditation, qualification, training and currency. 

Australian, state and territory governments should create common information platforms and share technologies to enable collaboration in the production, analysis, access, and exchange of information, data and knowledge about climate and disaster risks. 

Australian, state and territory governments should develop consistent processes for the classification, recording and sharing of fuel load data. 

Australian, state and territory governments should prioritise the implementation of harmonised data governance and national data standards. 

Australian, state and territory governments should ensure greater consistency and collaboration in the collation, storage, access and provision of data on the distribution and conservation status of Australian flora and fauna. 

Australian, state and territory governments should agree to: 
(1) develop consistent and compatible methods and metrics to measure health impacts related to natural disasters, including mental health, and 
(2) take steps to ensure the appropriate sharing of health and mental health datasets. 

Australian, state and territory governments should establish a national register of fire and emergency services personnel, equipment and aerial assets. 

Australian, state and territory governments should continue to develop a greater capacity to collect and share standardised and comprehensive natural disaster impact data. 

The State equip itself to undertake rapid air quality monitoring in any location in Victoria, to: • collect all relevant data, including data on PM , carbon monoxide and ozone; and 2.5 • ensure this data is used to inform decision-making within 24 hours of the incident occurring.

Governments should task the Australia–New Zealand Emergency Management Committee with leading the development of guidelines for the collection and dissemination of natural hazard mapping, modelling and metadata. Guidelines should be developed for all hazards that need to be modelled and mapped at the local/regional level and where consistency across regions is desirable.

Governments at all levels should make new and currently held natural hazard data publicly available in accordance with open public sector information principles. When collecting new natural hazard data or undertaking modelling, all levels of government should:
• make information publicly available unless it would not be in the public interest to do so
• use private-sector providers where cost effective, and use licencing arrangements that allow for public dissemination. Where there are costs involved in obtaining intellectual property rights for existing data, governments should weigh up these costs against the public benefits of making the data freely accessible
• apply cost recovery where governments are best placed to collect or analyse specialist data for which the benefits accrue mostly to private sector users.

Increased automation and outsourcing of observations

the state take into account any outcomes from the Commonwealth Government’s flood mapping reviews in the continual development of the Victorian flood database and to incorporate into the database flood data currently held by Melbourne Water.

the state establish standards for flood mapping to ensure they are kept contemporary and meet the purposes of landuse risk planning and emergency response. In doing so, maps should extend where appropriate to include Probable Maximum Flood, over a range of Annual Exceedence Probability levels and be explicitly linked to a stream gauge.

the state ensure that regional and local flood plans incorporate all available flood mapping and intelligence, including assessments of levees and flood consequence information.

the state, in consultation with Bureau of Meteorology and Melbourne Water, take the necessary action to ensure that all flood warnings issued are linked to the geographical location of the gauge the data was derived from.

The Fire Services develop a program that enables all communication mediums, including social media and agency websites, to be monitored in real time to provide quality assurance for outgoing messages and additional sources of information and intelligence relating to an emergency

The Department of Sustainability and Environment significantly upgrade its program of long-term data collection to monitor and model the effects of its prescribed burning programs and of bushfires on biodiversity in Victoria.

The Department of Sustainability and Environment conduct biodiversity mapping identifying flora, fauna and any threatened species throughout Victoria and make the results publicly available. The format used should be compatible with that used for Bushfire-prone Area mapping.

The State identify a central point of responsibility for and expertise in mapping bushfire risk to: ■ review urgently the mapping criteria at present used by the Country Fire Authority to map the Wildfire Management Overlay, to ensure that the mapping used to determine building and planning controls is based on the best available science and takes account of all relevant aspects of bushfire risk; ■ map and designate Bushfire-prone Areas for the purposes of planning and building controls, in consultation with municipal councils and fire agencies; ■ finalise the alignment of site-assessment methods for planning and building purposes, taking into account bushfire risk to human safety as well as to property.

The Country Fire Authority and the Department of Sustainability and Environment improve mapping support in the following ways: ■ DSE providing mapping data free of charge to emergency response agencies; ■ greatly increasing the CFA’s ‘write’ access to FireMap for incident management team staff; ■ establishing a joint DSE–CFA training program to ensure that mapping officers in level 2 and 3 incident management teams are fully trained in using FireMap, including in producing fire prediction maps; ■ requiring before the 2010–11 fire season that FireMap be used for joint incidents.

Biosecurity Victoria should enhance controls to provide assurance regarding data integrity. This process should include:
• working with local government to provide accurate and complete property data across the state
• enhancing processes for ensuring consistent notification of disease events across regions
• reviewing all processes related to the collation, input, processing, output and protection of data to improve the integrity of the system.

The Committee recommends that the Australian Government, through the Australian Bureau of Statistics, ensure that:
- accurate and consistent methods of measuring the numbers and the impact of tourists and other non-residents in coastal areas are undertaken to enable resources to be better matched with demand for infrastructure and services
- improved data on long-term demographic trends in coastal areas is made available to assist in coastal zone planning and management

The Committee recommends that the Australian Government establish a National Coastal Zone Database to improve access to and consistency of information relevant to coastal zone adaptation. The National Coastal Zone Database should be an online portal that allows ready access to:
- ‘first pass’ National Coastal Vulnerability Assessment data
- state and local Digital Elevation Modelling
- National Climate Change Adaptation Research Facility reports
- federal Local Adaptation Pathways Program reports
- state and local coastal vulnerability assessment results

The Committee recommends that the Department of Climate Change share all data collected through vulnerability assessments undertaken as part of the Australian Government Local Adaptation Pathways Program on the proposed National Coastal Zone Database (see also recommendation 42).

The Committee recommends that the National Coastal Zone Database be expanded over time to include information on environmental data and management and planning information relevant to the coastal zone.

That DPI upgrades the Crop Health Services diagnostic database so that it alerts PSB and PIRVIC to the receipt of samples from nearby areas with similar symptoms and can be linked to other PIRVIC diagnostic databases.

That DPI establishes a system to ensure the security of all samples at all times, but particularly during their handling and transport.

That all emergency service agencies, CFA and DSE in particular, give greater priority to information management – especially the collection, maintenance and quality control of base data sets necessary for planning, operations and program evaluation.

That DSE and CFA map all unplanned fires greater than four hectares on public and private land in order to further develop an understanding of the risk to rural Victoria from unplanned fires.

That DSE and CFA, recognising that the Bureau of Meteorology does not routinely store all variables required to produce the calculations and indices necessary for research and planning into fire occurrence and behaviour, develop appropriate systems to ensure that such current and historical information is readily available and accessible.

That DSE institute additional routine data storage and analysis to supplement current climate records with at least daily 3 pm values for the Grassland and Forest Fire Danger Index, and Keetch-Byram Drought Index, for selected high quality stations representing a cross-section of environments throughout Victoria. 

That Government acknowledge the importance of spatial information as a key element of planning, operations and program evaluation, and support the Geospatial Emergency Information Network as a means of ensuring integrated and co-ordinated information management on a whole-ofGovernment basis.

The Committee recommends that Emergency Management Australia be required to participate in the development and delivery of spatial information systems as part of a national approach to emergency planning and management data. The first priority in policy development and of systems should be related to bushfire hazards.

The Committee recommends that Geoscience Australia take responsibility, in conjunction with Emergency Management Australia, for developing a national spatial data policy to coordinate the development of data systems, the collection of data and the sharing of data between all the emergency response agencies across Australia, and that both agencies participate in the development and delivery of spatial information
systems as part of a national approach to emergency planning and management data. The first priority in policy development and of systems should be related to bushfire hazards.

The Committee recommends that the 1:100,000 national mapping program be accelerated to achieve an average life of no greater than 10 years with priority given to those areas most susceptible to national disasters.
