- Climate Safety
- Medium
- Flood
- Kirwan faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Intense rainfall events can lead to riverine and flash flooding.
- Bushfire
- Kirwan has a moderate bushfire risk due to surrounding bushland. Hot, dry conditions and strong winds can increase the likelihood of bushfires.
- Heat
- Kirwan experiences high temperatures, particularly during summer. Climate change is expected to increase the frequency and intensity of heatwaves, posing a risk to vulnerable populations.
- Storm
- Notable storm risk — tropical cyclones and severe thunderstorms in summer months
- Postcode
- 4817
- Highest high-risk exposure
- 14.9% of land (riverine flood)
Climate Safety Analysis
Kirwan in Queensland 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 Kirwan'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 Kirwan 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.
