Climate Safety Score
5.8/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Warrawong faces a moderate risk of flooding due to its low-lying areas and proximity to Lake Illawarra and several creeks. Intense rainfall events can lead to stormwater runoff exceeding drainage capacity.
- Bushfire
- The risk of bushfire in Warrawong is relatively low compared to other areas in NSW, but some areas near the escarpment face a moderate risk. Grassfires can also pose a threat during dry periods.
- Heat
- Warrawong is expected to experience more frequent and intense heatwaves in the future. The urban environment can exacerbate the heat island effect, leading to higher temperatures.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2502
- Highest high-risk exposure
- 11.2% of land (bushfire)
Climate Safety Analysis
Warrawong 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 Warrawong'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 Warrawong 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.
