Australia FloodScore™

FloodScore™ Property

Quickly evaluate and quantify flood risk to any property in Australia

Australia FloodScore™ provides property-level flood risk scores and flood risk information for all properties in Australia. You can use it to quickly evaluate and quantify flood risk. It’s available as a full or partial database, or as spatial layers.

Australia FloodScore provides proprty-level flood risk data for the whole of Australia. It has been designed to support insurers and brokers in making quicker, more accurate decisions around flood risk.

The data is derived using the same advanced modelling techniques that are used by some of Australia's major insurers, and integrates the most complete and up-to-date flood and building stock data available.

Australia FloodScore uses the advanced flood modelling techniques developed for Australia FloodMap™. It incorporates the most current hydrology data from the Geoscience Australia and BOM, and extensive LiDAR coverage including the entire Geoscience Australia LiDAR database.

This data is used to formulate a risk index, which reflects the average annual loss (AAL) for a property. This ‘flood score’ takes into account the likelihood of an individual property being flooded due to rainfall, overflowing rivers or tidal surges, as well as the damageability for different property classes. To improve the stability and accuracy of the flood scores, they’re derived from a range of return periods (1 in 20, 75, 100, 250, 500 and 1000 year scenarios), along with complex risk-scoring algorithms.

"Rainfall has increased across parts of northern Australia since the 1970s. As the climate warms, heavy rainfall is expected to become more intense. Projecting the occurrence and severity of future extreme events is very important for future climate adaptation."
