Overall Risk Score
Hazard Breakdown
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 Auchenflower
Flood
Auchenflower faces a moderate to high risk of flooding, primarily due to its proximity to the Brisbane River and its lower-lying areas. Intense rainfall events can lead to riverine flooding, impacting properties near the riverbanks and in depressions.
Key drivers:
- ·Increased rainfall intensity
- ·Brisbane River surge
Bushfire
The risk of bushfire in Auchenflower is very low due to its predominantly urban setting and lack of significant, contiguous bushland within the suburb itself. Any potential risk would be from embers or fires spreading from nearby, more vegetated areas.
Key drivers:
- ·Proximity to Mt Coot-tha
- ·Dry vegetation periods
Heat
Auchenflower experiences a high risk from heatwaves, characterized by rising average temperatures and an increasing frequency of extreme heat days. Urban heat island effects are likely exacerbated by dense housing and limited green space in some areas.
Key drivers:
- ·Rising average temperatures
- ·Urban heat island effect
Coastal
Auchenflower is not directly exposed to coastal inundation or erosion risks as it is located inland from the immediate coastline, although it is situated on the Brisbane River which can be affected by storm surges.

What This Means for Property Owners
Insurance Outlook
Moderate to High premiums possible in flood-prone areas. Increasing scrutiny on flood cover.
Price Impact
Potential negative impact on property values in high-risk flood zones. Heat resilience may become a selling point.
Buyer Checklist
- 1.Review flood maps and historical flood data.
- 2.Check insurance policy details and costs.
- 3.Assess proximity to the Brisbane River and potential flood impacts.
- 4.Evaluate property elevation and drainage.
- 5.Consider heat resilience features (e.g., insulation, air conditioning, shading).
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 Auchenflower's Climate Risk Profile
Auchenflower, situated approximately 4 kilometres west of the Brisbane CBD, is a well-established inner-western suburb known for its leafy streets and proximity to the Brisbane River. Its geographical position, particularly the areas closer to the river and in natural depressions, makes it susceptible to flooding during periods of intense rainfall and riverine events.
The suburb's urban character, while offering convenience, contributes to the urban heat island effect, exacerbating the risk and impact of heatwaves. With Brisbane experiencing a general warming trend and an increase in the frequency and intensity of extreme heat days, residents of Auchenflower are increasingly vulnerable to heat stress.
Conversely, Auchenflower's risk profile for bushfire is very low. The suburb is largely developed with residential properties and lacks extensive, contiguous areas of dense bushland that typically fuel major bushfires. While embers could potentially travel from nearby vegetated areas like Mount Coot-tha, the direct threat within the suburb itself is minimal.
Coastal inundation is not a direct concern for Auchenflower, given its inland location relative to the open coast. However, the Brisbane River is tidal, and significant storm surges associated with cyclones or severe weather systems further downstream could potentially influence water levels within the river, though this is a less prominent risk compared to direct riverine flooding from rainfall.
Overall, Auchenflower presents a mixed climate risk profile. The primary concerns revolve around water-related hazards (flooding) and extreme heat, both of which are projected to intensify in the coming decades. Mitigation and adaptation strategies should focus on these key areas to enhance resilience.

Frequently Asked Questions
What are the main flood risks for Auchenflower residents?
The primary flood risk in Auchenflower stems from the Brisbane River, particularly for properties located in low-lying areas adjacent to the river. Intense rainfall events can cause the river to overflow its banks, leading to significant inundation. Flash flooding from intense local rainfall can also occur in areas with poor drainage.
How will climate change affect heatwaves in Auchenflower?
Climate change projections indicate that Auchenflower, like much of Brisbane, will experience more frequent, intense, and longer-lasting heatwaves. The urban environment can exacerbate these effects through the urban heat island phenomenon, making it crucial for residents to prepare for extreme heat.
Is Auchenflower prone to bushfires?
Auchenflower itself is a predominantly urban suburb with limited bushland. Therefore, the direct risk of bushfire is very low. However, properties near the edge of the suburb bordering areas like Mount Coot-tha may face a low risk from embers or fire spread during severe fire conditions.
What is the risk of sea-level rise impacting Auchenflower?
Auchenflower is located inland from the direct coastline and is not significantly exposed to sea-level rise. The main water-related risk is riverine flooding from the Brisbane River, rather than coastal inundation.
What historical flood events have impacted Auchenflower?
Auchenflower has been significantly impacted by major floods along the Brisbane River, most notably in 1974, 2011, and 2022. These events caused widespread property damage and disruption for residents living near the river.
Are there specific council resources for flood information in Auchenflower?
Yes, Brisbane City Council provides extensive flood information, including flood maps and planning advice, on their website. Residents can use these resources to understand their specific property's flood risk.
