Hazard Breakdown
Climate Hazard Breakdown for Mount Isa
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.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development increasing runoff
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.
Key drivers:
- ·Prolonged drought conditions
- ·Increased frequency of heatwaves
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.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Mount Isa is located far inland and does not face any direct coastal risks such as sea level rise or coastal erosion.
Key drivers:
- ·Inland location
Wind
Notable wind risk — tropical cyclone wind fields
Storm
Notable storm risk — cyclones and thunderstorms
Social
Moderate social stability — growth regions
Energy
Elevated energy costs — high cooling demand

Learn moreAbout Mount Isa's Climate Risk Profile
Mount Isa, located in remote North West Queensland, is highly vulnerable to the impacts of climate change. The region already experiences extreme heat, and projections indicate that temperatures will continue to rise, leading to more frequent and intense heatwaves. This poses a significant threat to public health, especially for vulnerable populations such as the elderly and those with pre-existing medical conditions.
Bushfire risk is also a major concern for Mount Isa. The surrounding arid landscape and dry vegetation create ideal conditions for bushfires to ignite and spread rapidly. Prolonged drought conditions, exacerbated by climate change, further increase the risk of bushfires threatening properties and infrastructure.
Flooding is another hazard that Mount Isa faces. Heavy rainfall events can cause local rivers and creeks to overflow, inundating low-lying areas and disrupting transportation. Climate change is expected to increase the intensity of rainfall events, leading to more frequent and severe flooding.
While Mount Isa is not directly exposed to coastal hazards, the impacts of climate change on other regions can indirectly affect the city. For example, disruptions to supply chains and migration patterns could have economic and social consequences for Mount Isa.
Addressing these climate risks requires a comprehensive and coordinated approach. This includes implementing measures to reduce greenhouse gas emissions, adapting to the impacts of climate change, and building resilience in the community.
