Hazard Breakdown
Climate Hazard Breakdown for Chelmer
Flood
Chelmer is at high risk of flooding due to its proximity to the Brisbane River. Riverine flooding can inundate properties and disrupt infrastructure.
Key drivers:
- ·Increased rainfall intensity
- ·Rising river levels
Bushfire
Bushfire risk in Chelmer is relatively low, but some areas near green spaces are potentially vulnerable. Increased dry periods can elevate the risk.
Key drivers:
- ·Dry vegetation
- ·Increased temperatures
Heat
Chelmer experiences increasing heatwave intensity and frequency. Urban areas retain heat, leading to higher night-time temperatures.
Key drivers:
- ·Rising average temperatures
- ·Urban heat island effect
Coastal

Learn moreAbout Chelmer's Climate Risk Profile
Chelmer, located in Brisbane, Queensland, is increasingly vulnerable to the impacts of climate change. The most significant threat is riverine flooding, driven by increased rainfall intensity and rising river levels. The suburb's low-lying areas near the Brisbane River are particularly at risk.
Heatwaves are becoming more frequent and intense, posing health risks to vulnerable populations. The urban heat island effect further amplifies these risks, especially during summer months. Bushfire risk is relatively low but not negligible, particularly in areas bordering green spaces.
While Chelmer is not directly exposed to coastal hazards, the broader region is affected by sea level rise and storm surges. These events can indirectly impact Chelmer through disruptions to infrastructure and supply chains.
Addressing these climate risks requires a combination of mitigation and adaptation strategies. Reducing greenhouse gas emissions is crucial to slowing down the rate of climate change. Local adaptation measures, such as improved drainage systems and heatwave preparedness plans, are essential to protect the community.
