Distribution businesses annually attest to the Minister for Energy and Resources. The attestation should include specific reference to, but not limited to: Review of emergency management practices including but not limited to review of risks and risk controls and testing of revised controls following all major events and exercises.

The Victorian Government to work with the Commonwealth Government and telecommunications carriers to ensure that there are appropriate arrangements, via existing services or alternatives, for communities to stay connected for 72 hours without network power supply.

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 Victorian Government advocates for stronger telecommunications service reliability outcomes from the Australian Government, and associated telecommunications reviews.

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 fund the pilot of a ring levee development program in Northern Victoria to protect house and curtilage in flood-prone areas.

That the Victorian Government develop community-based initiatives and resource-sharing mechanisms, fostering resilience and solidarity among towns facing challenges from environmental disasters. These should ensure timely and effective responses to future crises, leveraging collective strength and kindness to aid in the recovery process.

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 ensure that the state’s existing culvert infrastructure in high-risk flood areas is fit for purpose, and that the Government also consult with local councils and other relevant stakeholders and prioritise betterment in any upgrade works deemed necessary.

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

That the Victorian Government further investigate options for increasing outlet capacity at Lake Eppalock. This investigation should involve:
- conducting a cost-benefit analysis to evaluate financial feasibility
- extensive stakeholder engagement to gather input from affected parties and communities
- examination of environmental effects
- environmental risk assessments to understand potential impacts on local ecosystems, wildlife and water quality
- reviewing water-sharing arrangements to ensure: –appropriate adjustments to maintain equitable water distribution and –compliance with legal and regulatory requirements.

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 efficacy and impact of the Flemington Racecourse flood wall be considered as part of Melbourne Water’s review of mitigation in the Maribyrnong River catchment announced following the updated flood modelling.

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 ensure that major flood mitigation measures be assessed and reviewed to ensure they perform as intended.

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 investigate long term sustainable flood mitigation options for the Maribyrnong River.

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.

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 investigate the feasibility of installing one way valves on the outlets from the street and yard drainage from Evergreen Avenue (Rivervue Retirement Village).

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.

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. 

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.

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

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 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 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 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.

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 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.

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.

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 DSE and CFA as part of their long term planning, and in conjunction with the Commonwealth Bureau of Meteorology, consider ways in which evidence for climate change and El Niño–Southern Oscillation cycle impacts on the likelihood of unplanned fire, can be better incorporated into preparedness and response planning.

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.

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 CFA, DSE and MFESB continue to develop the partnership approach for fire safety with Local Government, industry and communities. 

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 DSE, with adequate resourcing, moves to a 12-month cycle of fire management to establish and maintain a more appropriate and balanced work program of prevention/mitigation and suppression.
