How to Interpret These Scores
Each hazard is scored from 0 (minimal risk) to 100 (severe risk). Scores are derived from BOM historical data, CSIRO climate projections, and state hazard authority mapping. A score of 50 means the property is in the moderate range — above average risk but not extreme. Scores above 67 indicate high risk requiring due diligence.
Insurance Cost Trajectory
Based on the hazard scores for these suburbs, current annual insurance premiums are estimated around A$6,028. With projected climate changes under RCP 8.5, premiums could rise to approximately A$8,439 by 2030 and A$15,673 by 2050. These projections align with Insurance Council of Australia data showing 28% average premium increases nationally between 2022-2025, with higher-risk areas seeing 80-120% increases.
Property Value Climate Impact
Rising insurance premiums directly impact property values. Research from the Insurance Council of Australia and climate risk analysts shows that properties in areas with higher climate risk can experience a climate value drag. For a median-priced home, this could mean a potential impact of around A$48,225 or more over time.
