Smarter Underwriting with
Property-Level Climate Risk Data
Integrate 8-hazard climate risk intelligence into your underwriting workflow. Improve pricing accuracy, reduce claims exposure, and meet AASB S2 disclosure requirements — with a complete report for any Australian address in about a minute.
AASB S2 climate disclosure commenced 1 July 2026. Insurers must report physical risk exposure across their underwriting portfolios. Rising uninsurability in high-hazard zones makes property-level risk data essential for sustainable portfolio management. Read the guide →

Built for Insurance Underwriting & Portfolio Management
ClimateNest delivers the property-specific risk intelligence that insurers need to price accurately, manage aggregate exposure, and satisfy regulatory requirements.
Precision Underwriting Data
Move beyond postcode-level rating bands. ClimateNest provides coordinate-level hazard scores for every Australian property — factoring in local topography, proximity to waterways, bushfire vegetation zones, coastal exposure, and micro-climate effects. Eight hazard categories ensure you don't miss emerging risks like extreme heat and subsidence that are worsening under climate change.
Portfolio Risk Aggregation
Aggregate property-level risk scores to understand your portfolio's exposure by product line (home, contents, strata, landlord, commercial), geographic region, and hazard type. Run scenario analyses to model claims frequency and severity under RCP 4.5 and RCP 8.5 projections. Identify concentration risk and adjust reinsurance and underwriting strategy accordingly.
Uninsurability Trajectory
ClimateNest's insurance trajectory model projects premium inflation and uninsurability timelines for each property out to 2050. Understand which policies are at risk of becoming unviable, model portfolio attrition, and inform strategic decisions about product design, pricing corridors, and risk appetite. Essential data for AASB S2 climate resilience disclosures.

The Insurance Climate Risk Challenge
Australian insurers are facing a perfect storm: rising claims from extreme weather, expanding uninsurable zones, and new regulatory requirements that demand granular portfolio-level climate risk data.
Claims Cost Escalation
Bureau of Meteorology data shows insured losses from extreme weather events exceeding $5B annually. Without property-level risk models, insurers cannot accurately price this exposure.
Regulatory Disclosure Pressure
AASB S2 requires insurers to disclose climate risk exposure across underwriting portfolios. Regulators expect scenario-based quantification, not qualitative narratives.
Portfolio Attrition Risk
Properties in high-risk zones face rapidly rising premiums. Insurers without granular risk models may inadvertently underwrite unprofitable business or walk away from otherwise viable books.
