Flood risk metrics
Supporting measurable improvements in flood risk management
The Queensland Flood Risk Management Framework (QFRMF) sets the direction for flood risk management statewide, outlines roles and responsibilities, and guides and support decision-making by councils.
Five metrics have been developed to support measuring improvements in flood risk management and resilience for all Queensland communities. Each metric seeks to capture aspirations of Flood Risk Management (FRM) practices prescribed under the QFRMF. The metrics have been developed by the Queensland Reconstruction Authority (QRA) in consultation with stakeholders.
These metrics have been measured for all local government areas statewide to develop the 2020-2021 baseline metrics report. Annual progress reports against the baseline metrics will be presented to the Queensland Resilience Coordination Committee (QRCC). The first report will focus on projects and funding being delivered between 1 July 2021 to 30 June 2022.
Increase in the investment in preparing for and preventing the detrimental impacts of flooding on our communities.
- M1a: Annual investment (AUD$) in flood risk management, by source agency.
- M1b: Percentage of M1a which was allocated following an event.
Metric 1 captures the funding approved for flood risk management activities across the state. This metric is informed by QRA administered grant and funding programs (listed in Table 2) and only includes investment in FRM projects and activities that aim to prevent and/or prepare for flooding. It also differentiates this investment from that targeted at response and recovery.

Land use planning decisions consider natural hazards and mitigate risks as far as practicable to ensure long-term sustainability of our communities
- M2a: Number of councils with SPP2017 compliant local planning scheme
- M2b: Area of residential zoned land within the QFAO 1% AEP extent
This metric captures the number of councils with a local planning scheme which is considered consistent with the risk-based planning principles outlined in the State Planning Policy 2017 (SPP). The SPP defines matters of state interest in land-use planning and development, of which Natural Hazards Risk and Resilience is one. Guidance to support the implementation of the SPP discusses the use of a risk-based assessment considering both current and future climate conditions and future urban growth plans.
Metric 2b captures the percentage of residential-zoned land within the 1% flood extent, which is defined by the existing state-wide Queensland Floodplain Assessment Overlay (QFAO). Where QFAO data does not exist (most notably in South East Queensland), Councils were asked to provide the analysis using their 1% AEP flood extent. Some councils were unable to provide such information, resulting in the data being incomplete, mostly for remote and rural areas.
Flood risk is understood for current and future conditions
- LGAs consists of no level 3 flood studies
- LGAs that have some level 3 flood studies with some gaps
- LGAs with Full coverage of level 3 flood studies
- M3b: Value (AUD$) of investment in flood studies that year
This metrics seeks to capture the percentage area of habitable floodplains within a Local Government Area (LGA) covered by contemporary flood studies. Habitable floodplain is defined as populated places of an urban settlement (town or city) and the population indicated by ABS Census 2011 figures. A contemporary flood study utilises 2-dimensional hydrodynamic flood modelling software with a version of that software no older than five years, along with hydrological inputs that were generated using the latest ARR2019 guidelines. For this metrics, a Level 3 flood study is considered to be a contemporary flood study.
QRA currently has limited access to local flood study data, as such, reporting will be limited to the available data. Ideally future reports will expand to cover the full extent of flood studies undertaken in Queensland, as more data is shared with the state government (in accordance with the expectations articulated in the QFRMF).
Flood information is publicly available and accessible
- M4a: Number of councils providing GIS and PDF outputs of flood studies on their website
- M4b: Number of councils with property level information portals
- M4c: Number of councils with disaster dashboards
This metric captures the number of councils that provide key flood awareness information on their public websites. Under the QFRMF, responsibility for flood risk management and flood awareness information generally rests with local governments, as they are the major service provider to communities and are responsible for managing local development.
Flood awareness information for this metric is sourced through desktop research of council’s websites and subsequent council engagement. The metric focuses on the provision of the flood studies, property level information portals, and disaster dashboards.
Queensland has a best practice network to prepare for and respond to flooding
- M5a: Total number of river and rain assets for the primary purpose of flood warning
- M5b: Percentage of M5a which are automatic gauges
- M5c: Number of councils utilising a flood intelligence system
- M5d: Number of gauges which underwent a minor-moderate-major categorisation review
- M5e: Total number of new assets (signs, cameras, gauges) installed that year
- M5f: Total number of creek assets for the primary purpose of flood warning
This metric captures improvements made to Queensland’s flood warning infrastructure network. In Queensland, flood warning infrastructure assets are owned and operated by more than 60 entities including state and local government, the private sector, and the Bureau of Meteorology.
For this metric, flood warning infrastructure assets counted in the analysis conform to the Bureau of Meteorology's National Flood Warning Infrastructure Standard and this initiative aligns with the National Framework for Flood Warning Infrastructure. Flood warning infrastructure assets information is sourced from Bureau of Meteorology's Service Level Specification (SLS) for Flood Forecasting and Warning Services for Queensland. Metrics M5a, M5b, M5c, and M5d will be captured in the baseline report, with M5e and M5f requiring further analysis and will be captured in the first annual report.
Metrics Baseline Report 2020–2021
The Queensland Flood Risk Management Framework (QFRMF) Metrics Baseline Report provides data on activities undertaken between 1 July 2020 to 30 June 2021. Progress will be measured against this baseline annually to monitor change in Flood Risk Management (FRM) practices prescribed under the QFRMF.
The data sourced for the baseline report involved both qualitative and quantitative analysis, and included desktop studies, analysis of existing datasets, and engagements with councils. The QRA notes there are some limitations in the amount of local data available in some local government areas, in particular for flood studies, councils local planning and land use, and the use of flood intelligence systems.
