Is Macquarie Marshes, NSW Climate Safe? 2026 Assessment
Climate Safety Score
7.2/10Climate risk is high — address assessment recommended
Key Facts
- Climate Safety
- High
- Flood
- Macquarie Marshes is highly susceptible to flooding due to its location within a major floodplain. Increased rainfall intensity and frequency will exacerbate this risk.
- Bushfire
- The area surrounding Macquarie Marshes has a moderate bushfire risk due to the presence of grasslands and woodlands. Drier conditions and higher temperatures will increase the likelihood of bushfires.
- Heat
- Macquarie Marshes will experience more frequent and intense heatwaves. This poses a significant risk to vulnerable populations and agricultural activities.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2831
- Highest high-risk exposure
- 16.5% of land (bushfire)
Climate Safety Analysis
Macquarie Marshes in New South Wales has an overall climate safety rating of High. 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 Macquarie Marshes's climate safety include heat, flood, bushfire. 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 Macquarie Marshes 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.

Macquarie Marshes (postcode 2831) 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 bushfire (16.5% of land in high-risk zones), riverine flood (5.8% of land in high-risk zones), surface flood (5.4% of land in high-risk zones). Exposure is not uniform across Macquarie Marshes — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
