Is Carss Park, NSW Climate Safe? 2026 Assessment
Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Carss Park is located near the Georges River and Botany Bay, making it susceptible to flooding from heavy rainfall and storm surges. Climate change is expected to increase the frequency and intensity of extreme rainfall events, exacerbating flood risk.
- Bushfire
- While Carss Park is primarily a residential area, some properties are located near bushland, posing a moderate bushfire risk. Hotter and drier conditions due to climate change are expected to increase the likelihood of bushfires.
- Heat
- Carss Park is expected to experience more frequent and intense heatwaves due to climate change. This can pose a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2221
- Region
- Greater Sydney
- Median property value
- $1.6 million
- Dominant hazard
- extreme heat (5/10)
- Highest high-risk exposure
- 17.9% of land (bushfire)
Climate Safety Analysis
Carss Park 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 Carss Park's climate safety include heat, flood, coastal. 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 Carss Park 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.
