Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.
Climate Hazard Breakdown for Brisbane CBD
Flood
Brisbane CBD faces a moderate risk of flooding due to its location near the Brisbane River and low-lying areas. Increased rainfall intensity and rising river levels are key concerns.
Key drivers:
- ·Increased rainfall intensity
- ·Rising river levels
Bushfire
The risk of bushfire in Brisbane CBD is relatively low due to its urban environment and limited vegetation. However, ember attacks from distant fires remain a potential threat.
Key drivers:
- ·Limited vegetation
- ·Ember attack potential
Heat
Brisbane CBD experiences a high risk of heatwaves, exacerbated by the urban heat island effect. Increased temperatures pose a significant threat to vulnerable populations.
Key drivers:
- ·Urban heat island effect
- ·Increased temperatures
Coastal
Brisbane CBD faces a high risk from coastal hazards due to its proximity to the Brisbane River and Moreton Bay. Sea level rise and storm surges are major concerns.
Key drivers:
- ·Sea level rise
- ·Storm surges

What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase due to flood and storm risks.
Price Impact
Properties in flood-prone areas may experience price reductions.
Buyer Checklist
- 1.Check flood maps and historical flood data.
- 2.Assess the property's vulnerability to heatwaves.
- 3.Inquire about insurance costs and coverage.
- 4.Consider the long-term impacts of climate change on property value.
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 Brisbane CBD's Climate Risk Profile
Brisbane CBD, the central business district of Queensland's capital, is particularly vulnerable to the impacts of climate change. Its low-lying geography and dense urban development contribute to significant risks from flooding, heatwaves, and coastal hazards.
Flooding is a major concern due to the suburb's location along the Brisbane River. Increased rainfall intensity and rising river levels, driven by climate change, are expected to increase the frequency and severity of flood events. The urban environment further exacerbates the risk by increasing runoff and reducing natural drainage.
Heatwaves pose a significant threat to the health and well-being of residents and visitors in Brisbane CBD. The urban heat island effect, caused by the concentration of buildings and paved surfaces, traps heat and raises temperatures, making the area particularly vulnerable during heatwaves. Climate change is projected to increase the frequency and intensity of heatwaves, further exacerbating this risk.
Coastal hazards, including sea level rise and storm surges, also pose a threat to Brisbane CBD. The suburb's proximity to the Brisbane River and Moreton Bay makes it vulnerable to inundation from rising sea levels and storm surges. Climate change is expected to accelerate sea level rise and increase the intensity of storms, increasing the risk of coastal flooding and erosion.
Addressing these climate risks requires a comprehensive approach that includes reducing greenhouse gas emissions, adapting to the impacts of climate change, and building resilience in the community. This includes investing in flood protection infrastructure, implementing heat mitigation strategies, and planning for sea level rise.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.

Frequently Asked Questions
What are the main climate change risks for Brisbane CBD?
Brisbane CBD faces significant risks from flooding, heatwaves, and coastal hazards due to its location and urban environment. Climate change is expected to worsen these risks in the future.
How is Brisbane City Council addressing climate change?
Brisbane City Council has implemented various initiatives to reduce greenhouse gas emissions, adapt to the impacts of climate change, and build resilience in the community. These include investing in flood protection infrastructure, planting trees, and developing heat action plans.
What can I do to protect my property from flooding in Brisbane CBD?
You can take several steps to protect your property from flooding, such as elevating your home, installing flood barriers, and purchasing flood insurance. It is also important to stay informed about flood warnings and evacuation plans.
How can I stay safe during a heatwave in Brisbane CBD?
During a heatwave, it is important to stay hydrated, avoid strenuous activity, and seek shelter in air-conditioned environments. Check on vulnerable neighbors and family members, and be aware of the signs of heatstroke.
What is the urban heat island effect, and how does it affect Brisbane CBD?
The urban heat island effect is a phenomenon where urban areas experience higher temperatures than surrounding rural areas due to the concentration of buildings and paved surfaces. This effect exacerbates heatwaves in Brisbane CBD, making it particularly vulnerable to extreme heat.
Are there specific areas in Brisbane CBD that are more prone to flooding?
Yes, low-lying areas near the Brisbane River are more susceptible to flooding. It's important to check flood maps provided by the Brisbane City Council to understand the specific risks for your location.
