About Climate Risk in New South Wales

NSW suburbs face combined flood, bushfire, and coastal erosion risks across a diverse geography — from flood-prone river systems in western Sydney to bushfire-interface suburbs in the Blue Mountains, Central Coast, and Sutherland Shire. Coastal suburbs face increasing storm surge and erosion risk under sea level rise projections.

ClimateNest suburb assessments are built using Bureau of Meteorology (BOM) historical hazard data, CSIRO future climate projections under SSP2-4.5 and RCP8.5 scenarios, state-specific hazard overlays from emergency services and planning authorities, and actuarial data. Every assessment includes current hazard scores (0–100), projected scores for 2030 and 2050, local geographic evidence, insurance outlook, and property owner recommendations.
