Flood
South Brisbane is susceptible to flooding due to its proximity to the Brisbane River. Riverine flooding can occur during periods of heavy rainfall.
Key drivers:
- ·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

What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase due to the increasing risk of flooding and other climate-related events.
Price Impact
Properties in flood-prone areas may experience a decrease in value due to increased risk and insurance costs.
Buyer Checklist
- 1.Check flood maps and historical flood data.
- 2.Assess the property's vulnerability to heatwaves.
- 3.Consider the potential impact of sea level rise.
- 4.Review insurance options and costs.
- 5.Investigate council plans for climate adaptation.
How the region's climate is projected to change
Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.
Temperature
+0.5 to 1.1°C by 2030
Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.
Rainfall
Winter rain down up to 15% by 2030
The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.
Fire weather
Harsher, magnitude uncertain
High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.
Sea level
+0.12 m by 2030
At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

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.
