The NSW Government’s 2024 Hawkesbury-Nepean River Flood Study provides the most up to date, reliable information on how floods impact this area in Western Sydney.

The Study will support decision making on emergency management, risk reduction and mitigation, land use planning and infrastructure investment such as road upgrades in one of Australia’s most dangerous flood risk areas.

You can find out more about the 2024 Hawkesbury-Nepean River Flood Study on the NSW Reconstruction Authority’s webpage. The complete Flood Study, including technical volumes and maps, is available on the NSW Flood Data Portal.

This animation shows how modelling undertaken for the Flood Study matches data from recent floods, making us very confident in the results.
