Every hazard on the record for a NSW address, in one place.
Government-mapped flood, bushfire, coastal and fire-history exposure, plus climate projections from NSW modelling — each cited to its source. Deterministic and factual: no AI interpretation, no guesswork, no risk rating.
What this tool does
Checks whether your property falls within government-mapped hazard zones for flood, bushfire, coastal erosion, and fire history, and shows projected temperature and rainfall changes from NSW climate modelling (NARCliM 2.0), each cited to its government source and date.
What this tool does not do
It does not predict whether your property will flood, burn, or be damaged. It does not assess your building's construction, resilience, or insurability. It is not an insurance assessment, engineering report, or financial advice. It reports exposure to mapped hazards — not probability of loss.
Where the data comes from
NSW Planning Portal (flood overlays), NSW Rural Fire Service (bushfire prone land), SEPP Resilience & Hazards 2021 (coastal zones), NPWS (fire history), and NARCliM 2.0 via AdaptNSW (heat projections). All government sources, queried live.
Five hazards assessed independently
Flood
EPI flood overlay status, council flood study ARI depths, and satellite water detection.
NSW Planning Portal + SES flood studies
Bushfire
RFS Bush Fire Prone Land classification and estimated BAL band from vegetation proximity.
NSW Rural Fire Service BFPL dataset
Coastal
SEPP Resilience and Hazards coastal zone mapping. Erosion and inundation exposure.
SEPP (Resilience and Hazards) 2021
Fire History
Historical fire scar records from NPWS. Proximity to burn areas over the past 20 years.
NSW National Parks fire history
Heat Trajectory
Projected temperature change to 2099 under SSP2.45 and SSP3.70 scenarios. 4km grid resolution.
NARCliM 2.0 (ACCESS-ESM1-5 GCM)
Compound Interactions
Bushfire + extreme heat. Flood + coastal inundation. Where mapped hazards overlap at an address, the report names the overlapping pair and the recognised interaction.
Overlapping hazard categories, flagged factually
What you get: sample assessment
This is a real output for a specific property near Windsor, Hawkesbury LGA — one of the most multi-hazard-exposed regions in NSW. Every number comes from a government dataset. Nothing is estimated or approximated.

Exposure to published data — not a risk rating or prediction.
Near Windsor, Hawkesbury LGA
Methodology v1.0
Property is within a flood planning area (EPI overlay). The Hawkesbury-Nepean is one of the highest flood-risk catchments in Australia — 90,000+ people live below the probable maximum flood level.
Source: NSW Planning Portal EPI Flood layers
Bush Fire Prone Land — the property is within an area mapped by the NSW Rural Fire Service. Construction must comply with AS 3959 and may require a formal BAL assessment before DA lodgement.
Source: NSW RFS Bushfire Prone Land Map
2 recorded fire events at this location. Areas with repeated burn history face higher risk of future fire — vegetation regrowth creates fuel loads that accumulate over 5-10 year cycles.

Days over 35°C projected to increase from 14/yr to 52/yr by 2090 under high emissions (SSP3-7.0). Western Sydney is one of the fastest-heating regions in the country — Penrith already records the highest urban temperatures in Australia.

Not within any SEPP (Resilience and Hazards) 2021 coastal hazard zone. Inland properties are not exposed to coastal erosion or tidal inundation — but may still face riverine flood risk (assessed separately above).

Overlapping hazard categories at this address
Bushfire + Fire History — repeated burn history in a bushfire-prone area, accumulated fuel loads
Bushfire + Heat — rising temperatures dry vegetation and extend fire seasons
Flood + Heat — a warmer atmosphere holds more moisture, driving more intense convective storms
Climate impacts can cascade and compound across systems (IPCC AR6 WGII, high confidence).
Mean Temperature Change
+2.1°C
Projected increase in mean near-surface temperature by 2090 under SSP3-7.0. This shifts the entire distribution — what is currently a “hot year” becomes the new average.
NARCliM 2.0 · ACCESS-ESM1.5 · 4km grid
Precipitation Trend
-0.3 mm/day
A drying trend means less frequent rainfall — but when rain does come, it tends to be more intense. This paradox increases both drought and flash flood risk simultaneously.

How to read this
Exposure, not a rating: the report lists which government-mapped hazards apply to the address and the published climate projections for the location. It is not scored, ranked, or colour-coded into a risk verdict — a coastal town can face fewer heat days than a hot western suburb, so a single headline number would mislead.
Deterministic: the same address always returns the same result. No AI interpretation, no machine-learning model, no probabilistic element — a direct function of which government spatial layers intersect the property and the NARCliM projection at the nearest 4km grid cell.
Not a prediction: it reports hazard exposure, not the probability of loss. Property-specific factors (construction type, floor height, vegetation management) are not included.
Why these hazards matter — the national picture
These are not PlotDetect numbers. They are from APRA, the Insurance Council of Australia, and the IPCC — the institutions that set prudential standards and measure catastrophe losses.

Projected flood loss increase by 2050
Flood is the most climate-sensitive weather peril. 50% of all losses are concentrated in just 10% of regions.

Why hazard exposure matters now
Insurance repricing
Insurers are repricing property risk based on climate exposure. Properties with unassessed hazards face premium increases or coverage withdrawal.
APRA climate risk self-assessment
APRA requires financial institutions to assess climate risk exposure. Property portfolios need hazard data at the individual address level.
Pre-purchase due diligence
A property in a flood zone that is also on bush fire prone land with projected heat increase has a fundamentally different risk profile. Buyers need to see the compound picture.
