Climate Safety Score
7.2/10Climate risk is high — address assessment recommended
Key Facts
- Climate Safety
- High
- Flood
- Mount Isa faces a moderate risk of flooding, primarily from heavy rainfall events that can cause local river and creek overflows. The risk is exacerbated by the city's location in a natural drainage basin.
- Bushfire
- The bushfire risk in Mount Isa is high due to the surrounding arid landscape and dry vegetation. Hot, dry conditions and strong winds can quickly spread fires, threatening properties on the city's outskirts.
- Heat
- Mount Isa experiences extreme heat, with very high average temperatures and frequent heatwave events. This poses significant health risks, especially for vulnerable populations and outdoor workers.
- Storm
- Notable storm risk — tropical cyclones and severe thunderstorms in summer months
- Postcode
- 4825

- 12.2% of land (riverine flood)
Climate Safety Analysis
Mount Isa in Queensland 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 Mount Isa's climate safety include heat, flood, bushfire. 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 Mount Isa 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.
