- ·Increased rainfall intensity
- ·Urban development
Bushfire
The risk of bushfire in South Brisbane is relatively low due to its urban environment and limited vegetation.
Key drivers:
- ·Limited vegetation
- ·Urban density
Heat
South Brisbane experiences high temperatures during summer, with increasing frequency of heatwaves due to climate change.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
South Brisbane is at risk from coastal hazards due to its location near the Brisbane River and Moreton Bay. Sea level rise and storm surges pose a threat.
Key drivers:
- ·Sea level rise
- ·Storm surge
Wind
Notable wind risk — tropical cyclone wind fields

Learn moreAbout South Brisbane's Climate Risk Profile
South Brisbane, located along the Brisbane River, is particularly vulnerable to flooding. The combination of increased rainfall intensity and rising sea levels is expected to increase the frequency and severity of flood events. The urban environment also contributes to the urban heat island effect, increasing the risk of heatwaves.
Bushfire risk is relatively low due to the suburb's urban density and limited vegetation. However, the potential for coastal hazards, such as storm surges and erosion, is a growing concern. Climate change projections indicate a significant increase in the frequency and intensity of extreme weather events, including heatwaves and floods.
Adaptation measures are crucial to mitigate the impacts of climate change in South Brisbane. These include improving flood defenses, implementing urban cooling strategies, and enhancing coastal protection measures. Community awareness and preparedness are also essential to reduce vulnerability to climate-related risks.
Long-term planning should consider the potential impacts of climate change on infrastructure, property values, and community well-being. Sustainable development practices and climate-resilient infrastructure are necessary to ensure the long-term viability of South Brisbane.
