- Medium
- Flood
- Kotara South faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Intense rainfall events can lead to stormwater runoff and potential riverine flooding.
- Bushfire
- The bushfire risk in Kotara South is relatively low due to the suburb's urban nature and limited vegetation. However, nearby bushland areas pose a potential threat during dry and windy conditions.
- Heat
- Kotara South experiences a moderate risk of heatwaves, particularly during the summer months. Urban heat island effects can exacerbate temperatures, posing a risk to vulnerable populations.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2289
- Highest high-risk exposure
- 20% of land (bushfire)
Climate Safety Analysis
Kotara South 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 Kotara South'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 Kotara South 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.
