Climate Risk Assessment for West End, Queensland
West End, a vibrant inner-city suburb of Brisbane, faces moderate to high risks from flooding and extreme heat, driven by its riverside location and dense urban environment. While bushfire risk is negligible, the increasing intensity of heatwaves and potential for riverine flooding due to climate change warrant attention.

Confidence: High
Hazard Breakdown
Climate Hazard Breakdown for West End
Flood
West End faces a medium to high risk of flooding due to its proximity to the Brisbane River and low-lying areas. Heavy rainfall events can lead to significant inundation, impacting properties and infrastructure.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise exacerbating riverine flooding
Bushfire
West End has a very low bushfire risk due to its predominantly urbanised environment and lack of significant bushland within its boundaries.
Key drivers:
- ·Limited vegetation
- ·Urban density
Heat
West End experiences a high risk of heat stress due to its dense urban fabric, limited green space, and the urban heat island effect, leading to significantly higher temperatures than surrounding rural areas.
Key drivers:
- ·Urban heat island effect
- ·Increased frequency and intensity of heatwaves
Coastal
While West End is not directly on the coast, its proximity to the Brisbane River means it can be indirectly affected by storm surges and sea level rise impacting river levels.
Key drivers:
- ·Sea level rise
- ·Increased storm surge intensity
Wind
Notable wind risk — tropical cyclone wind fields
Storm
Notable storm risk — cyclones and thunderstorms
Social
Moderate social stability — growth regions
Energy
Elevated energy costs — high cooling demand

Historical Climate Events
The 1974 Brisbane Flood caused widespread inundation across the city, with significant impact on low-lying suburbs including parts of West End.
SourceA severe thunderstorm caused flash flooding and significant damage across Brisbane, affecting areas near the Brisbane River.
SourceRecord rainfall led to major flooding in Brisbane, with extensive inundation impacting many suburbs, including low-lying areas of West End.
SourceBrisbane experienced a prolonged period of extreme heat, with temperatures exceeding 40°C on multiple days, impacting public health and infrastructure.

Projections based on CSIRO and BOM climate modelling. Scenario: RCP 8.5
| Hazard | Today | 2030 | 2050 |
|---|---|---|---|
| flood | 60 | 6.7(+0.7) | 7.5(+1.5) |

Learn moreAbout West End's Climate Risk Profile
West End, located just south of Brisbane's CBD, is a densely populated and culturally rich suburb known for its eclectic mix of residents, businesses, and heritage architecture. Its proximity to the Brisbane River places it within a natural floodplain, making it susceptible to inundation during periods of heavy rainfall and storm events.
The suburb's urban character, with a high concentration of buildings, roads, and limited green space, contributes significantly to the urban heat island effect. This phenomenon exacerbates the impact of heatwaves, leading to higher temperatures compared to surrounding areas and increasing the risk of heat-related illnesses and stress on infrastructure.
While West End is not directly exposed to coastal erosion or storm surges from the open sea, its connection to the Brisbane River means that sea level rise and increased storm intensity can indirectly influence flood levels within the suburb. This interaction between riverine and coastal influences presents a complex challenge for future flood management.
Bushfire risk in West End is minimal due to its highly urbanised nature and the absence of significant bushland reserves within its immediate vicinity. However, the general preparedness for natural disasters remains crucial for all Brisbane residents, including those in West End, given the broader regional climate risks.

Frequently Asked Questions
What is the main flood risk for West End residents?
The main flood risk for West End stems from the Brisbane River. Heavy rainfall events, especially when combined with high tides or storm surges, can cause significant inundation in low-lying areas of the suburb.
How does the urban heat island effect impact West End?
West End's dense urban environment, with many buildings and limited green space, traps heat. This 'urban heat island effect' makes the suburb significantly hotter than surrounding areas during heatwaves, increasing the risk of heat stress.
Is West End prone to bushfires?
No, West End has a very low bushfire risk. Its highly urbanised nature and lack of significant natural bushland mean it is not classified as a bushfire-prone area.
What can I do to protect my property from flooding in West End?
Consider elevating your home, installing flood barriers, ensuring your home insurance covers flood damage, and familiarising yourself with the Brisbane City Council's flood maps and emergency plans.
How will climate change affect West End in the future?
Climate change is projected to increase the frequency and intensity of heatwaves and heavy rainfall events, leading to greater flood risks and heat stress in West End. Sea level rise may also indirectly exacerbate riverine flooding.
Where can I find official flood information for West End?
The Brisbane City Council provides detailed flood information, including maps and preparedness guides, on their official website. You can also check the Queensland Fire and Emergency Services (QFES) website for broader disaster management information.
