Is Mardi, NSW Climate Safe? 2026 Assessment
Climate Safety Score
5.2/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Mardi faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
- Bushfire
- Bushfire risk in Mardi is moderate, with some areas bordering bushland. Drier conditions and higher temperatures are projected to increase bushfire frequency and intensity.
- Heat
- Mardi is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, particularly the elderly and those with pre-existing health conditions.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2259
- Highest high-risk exposure
- 9.9% of land (surface flood)
Climate Safety Analysis
Mardi in New South Wales has an overall climate safety rating of Medium. This multi-hazard assessment combines flood, bushfire, heat, coastal, and storm risk data with climate projections to 2050 from CSIRO and the Bureau of Meteorology.
Key factors affecting Mardi's climate safety include heat, flood. Each hazard is assessed independently and combined for an overall picture. Australia has warmed by approximately 1.5 °C since 1910, with flow-on effects to fire weather, extreme rainfall, and heatwave frequency.
Climate safety for property in Mardi is not uniform — it varies by address. Factors such as elevation, distance to waterways, proximity to bushland, and local drainage all influence actual risk at a specific property. Two nearby properties can have materially different risk profiles.
For a complete property-specific climate safety report for Mardi including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Mardi (postcode 2259) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are surface flood (9.9% of land in high-risk zones), bushfire (6.5% of land in high-risk zones), riverine flood (6.1% of land in high-risk zones). Exposure is not uniform across Mardi — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Frequently Asked Questions
Is Mardi safe from climate change?
No location in Australia is entirely immune to climate change impacts. Mardi has an overall Medium climate risk rating. Understanding the specific hazards at your property address — not just the suburb average — provides the most reliable risk picture.
Which climate hazard poses the biggest risk in Mardi?
The dominant hazard for Mardi depends on geography and local environment. Proximity to waterways elevates flood risk, while proximity to bushland increases bushfire risk. ClimateNest's multi-hazard analysis identifies the highest-risk hazards for any specific address.
How does Mardi compare to nearby suburbs for climate safety?
Nearby suburbs may have different climate risk profiles depending on elevation, vegetation cover, drainage patterns, and land use. ClimateNest allows comparison of climate safety scores across New South Wales suburbs.
Should I be concerned about buying property in Mardi?
Climate risk should be one factor in your decision, alongside price, location, and amenity. An informed buyer understands the specific risks at a property address and factors insurance costs and climate projections into their assessment of long-term value.
What climate projections should I know for Mardi?
Key projections for New South Wales from CSIRO include increased average temperatures, more frequent hot days, changes in rainfall seasonality, longer fire seasons, and potential increases in extreme rainfall intensity. These trends inform the long-term outlook for Mardi.
What share of Mardi is exposed to high surface flood risk?
ClimateNest's hazard overlay maps 9.9% of Mardi in high-risk zones for surface flood, with a further 83.3% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
