FloodAUS: Detailed Australian Riverine Flood Loss Model

Note: Use this section to paint the picture. How frequent are hailstorms in Australia? What sort of impact do they have? What financial impact?

The future risk of flooding in Australia is expected to increase due to climate change. The frequency and intensity of heavy rainfall events are expected to increase, leading to more frequent and severe flooding. This could have a significant impact on property values and insurance premiums, as well as the cost of rebuilding after a flood.

In 2022, the Insurance Council of Australia estimated that over one million private properties, or about one in 10 homes, have some level of flood risk in Australia. The Climate Council has estimated that the cost of flooding in Australia could reach $170 billion by 2050.

The latest release of FloodAUS is built upon high resolution riverine flood modelling and data to determine the return period of floodwater depth at individual addresses in Australia for over 500,000 unique simulated events. Building on our recognised expertise in developing and managing the National Flood Information Database (NFID) for the Insurance Council of Australia, peer reviewed research and on-the-ground post-event surveys, FloodAUS 4.0 has national coverage for modelling the impact of floods on property and businesses.
