Hazard Breakdown
Climate Hazard Breakdown for Gungahlin
Flood
Gungahlin faces a moderate risk of flooding, primarily from heavy rainfall events and potential overflow from nearby waterways. Development and urbanization can increase runoff, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Gungahlin has a moderate bushfire risk due to its proximity to grasslands and bushland areas. Hot, dry conditions during summer increase the likelihood of bushfires.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Gungahlin is experiencing increasing heatwave intensity and frequency. Urban areas tend to retain more heat, leading to higher temperatures compared to surrounding rural areas.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
Gungahlin is located inland and does not face any direct coastal risks such as sea level rise or coastal erosion.
Wind
Moderate wind risk — gusty summer winds
Storm
Moderate storm risk — spring/summer thunderstorms
Social
Moderate social stability — high public sector
Energy
Moderate energy costs — heating and cooling

Learn moreAbout Gungahlin's Climate Risk Profile
Gungahlin, located in the Australian Capital Territory, is projected to experience increased climate-related challenges in the coming decades. The primary concerns are rising temperatures, increased frequency and intensity of heatwaves, and potential for more severe flooding events.
The risk of flooding is driven by increased rainfall intensity and urban development, which reduces the land's capacity to absorb water. Bushfire risk remains a concern due to the surrounding grasslands and bushland, especially during dry periods. Heatwaves are becoming more frequent and intense, posing health risks to vulnerable populations.
While Gungahlin is not directly exposed to coastal hazards, the broader impacts of climate change, such as disruptions to supply chains and economic activity, can still affect the region. Addressing these challenges requires a combination of mitigation efforts to reduce greenhouse gas emissions and adaptation strategies to manage the impacts of climate change.
Local authorities and residents need to work together to implement measures such as improved drainage systems, bushfire management plans, and heatwave preparedness programs. These efforts will help to build a more resilient community that can withstand the challenges of a changing climate.
