Is South Lismore, NSW Climate Safe? 2026 Assessment
Climate Safety Score
7.2/10Climate risk is high — address assessment recommended
Key Facts
- Climate Safety
- High
- Flood
- South Lismore is highly vulnerable to flooding due to its location on the floodplain of the Wilsons River. The area has a history of significant flood events, and climate change is expected to increase the frequency and intensity of heavy rainfall, exacerbating the risk.
- Bushfire
- South Lismore has a moderate bushfire risk due to the presence of nearby bushland. While not directly adjacent to large forested areas, ember attack from distant fires remains a concern, particularly during dry and windy conditions.
- Heat
- South Lismore is experiencing an increase in the frequency and intensity of heatwaves. This poses a risk to vulnerable populations, including the elderly and those with pre-existing health conditions. Climate change is projected to further increase average temperatures and the number of extreme heat days.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2480
- Highest high-risk exposure
- 18.3% of land (bushfire)
Climate Safety Analysis
South Lismore 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 South Lismore'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 South Lismore 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.
