About the Portal

The Australian Flood Risk Information Portal (the portal) enables flood information, currently held by different sources, to be accessible from a single online location. The portal includes a database of flood study information and metadata (the Australian Flood Studies Database), and tools that enable users to search and download this material. The portal provides access to authoritative flood maps and flood studies, as well as information about surface water observations derived from the analysis of satellite imagery.

The portal incorporates tools that enable users to search, display and retrieve information. The data management tools and standards that have been developed for the portal will enable data custodians to standardise their data and upload it to the portal, or to make compliant data accessible via web services.

Following the devastating floods across Eastern Australia in 2011, the Australian Government initiated the Natural Disaster Insurance Review. This review highlighted the lack of consistency across the country in the way flood risk information was collected, and made available to users. The review also recognised the need for consumers to be aware of the natural disaster risks they may face, as well as the benefits of making flood risk information more readily accessible.

In response to these findings, the Government established the National Flood Risk Information  Project (NFRIP), this four  year project commenced on 1 July 2012. NFRIP supports the objectives of the National Strategy for Disaster Resilience (NSDR) adopted by Council of Australian Governments (COAG) in 2011, specifically, that Governments have effective arrangements in place to inform people about hazard and risk.

The portal is used by engineers, insurers and planners to find out what flood mapping information exists, and where, so they can better understand risks. Researchers and consultants can learn what work has been already occurred in their area of interest and to identify what data may be available for use in future studies.

A flood study is the scientific investigation of flooding in a particular area, usually the catchment of a river system. It may involve hydrologic and hydraulic investigations, and a statistical analysis of the frequency with which floods have occurred. The purpose of a flood study is to predict the depth of water and the extent to which it will inundate the landscape in a modelled flood event.

A flood map is the result of hydrologic and hydraulic analysis, by scientific subject matter experts, that take into account many factors when developing models for various scenarios. Such factors might include: terrain, water catchments, flood marks and information from historical floods. A map can represent the extent of a flood, the probability of that event occurring and sometimes the depth of inundation in the modelled area.


Flood maps can be found by searching the Australian Flood Risk Information Portal, where  mapping data is available this will be shown in the search results. While some flood studies don't include separate mapping data, maps relevant to the specific study can be found in many of the attached flood study documents.

The Australian Flood Studies Database (AFSD) is the national data catalogue of flood study information that underpins the portal. The AFSD contains general information for available studies, including the study location, date, commissioning organisation and lead consultant, and metadata on flood studies and information on flood risk. The metadata is created through a purpose-built data entry application, and adheres to the Flood Studies Data Model XML schema which can be used by data custodians to structure and share their flood information with the portal via webservices.

You can search for studies and maps in three main ways:

  1. By selecting an Area on the Map;
  2. By an address search; or
  3. You can specify your search parameters.

Many records in the database have the reports that incorporate maps, and can be downloaded directly from the Details section once you have identified a study you are interested in. If the study you're interested in has no downloads, you will need to contact the commissioning organisation identified in the study record to determine if a copy of the report is available.

Please check the Bureau of Meteorology - National Warnings Summary for details on flood warnings.
The Australian Flood Risk Information Portal does not hold information about current flood warnings.

Contact your local State Emergency Services if you require assistance in the event of a flood. The Australian Flood Risk Information Portal is not a response tool.

The portal is maintained by Geoscience Australia. Unless otherwise noted, all information is available for re-use under Creative  Commons 4.0 By Attribution (CC-BY) licensing.
The ownership of each flood studyremains with the commissioning organisation and/or author as indicated in the record on each study. Users of the database should refer to each specific flood study report to determine any constraints in its usage.

Your feedback is input to the continued development of the database and the portal. Please share your feedback via the portal's feedback button.

The portal contains information about flood studies. Some information may be incomplete or may have been superseded by new material. The studies themselves have been commissioned by other state and local government agencies. Issues with the accuracy of the study itself should be referred to the commissioning organisation. However, if you find that the database displays incorrect information about a flood study please share your feedback via the portal's feedback button.

Registered data custodians can add flood studies and maps to the portal. Please notify us of any other published flood studies that aren't currently included in the database, but may be suitable for release through the portal. Contact us via the portal's feedback button.
