Flood Risk Analysis
Number One, located in New South Wales, has a location-specific flood risk profile based on available data including proximity to waterways, elevation, and historical flood events. The Bureau of Meteorology (BOM) maintains river height and flood warning data for catchments across New South Wales.
Flood risk in Number One is shaped by local topography and catchment characteristics. Even within a single suburb, elevation differences can significantly change flood exposure. Properties near waterways or in low-lying areas warrant closer assessment.

ClimateNest assesses hazards at the address rather than the suburb, because exposure varies street by street within Number One. An address-level check is what tells you about a specific property before you buy, sell or insure it.
