Climate Safety Score
5.8/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Karana Downs is located near the Brisbane River and its tributaries, making it susceptible to flooding. Riverine flooding can occur after heavy rainfall events, inundating low-lying areas and impacting properties close to the waterways.
- Bushfire
- Karana Downs has some bushfire risk due to the presence of surrounding bushland. While not as high as some other areas, properties bordering or near bushland areas are potentially exposed to bushfire hazards.
- Heat
- Karana Downs experiences hot summers, with the potential for heatwaves. Increased temperatures due to climate change may exacerbate heat stress, particularly for vulnerable populations.
- Storm
- Notable storm risk — tropical cyclones and severe thunderstorms in summer months
- Postcode
- 4306
- Highest high-risk exposure
- 13.9% of land (tropical cyclone)
Climate Safety Analysis
Karana Downs 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 Karana Downs'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 Karana Downs 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.
