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 Calamvale
Flood
Calamvale faces a moderate flood risk, primarily due to its proximity to local creeks and drainage systems. While not directly on a major river, overland flow and flash flooding are the main concerns.
Key drivers:
- ·Increased rainfall intensity
- ·Urbanisation and impervious surfaces
Bushfire
The bushfire risk in Calamvale is relatively low, with limited direct interface with large, dense bushland areas. However, smaller pockets of vegetation and surrounding undeveloped land pose a minor risk.
Key drivers:
- ·Proximity to smaller vegetated reserves
- ·Dry conditions
Heat
Calamvale experiences a high risk from heatwaves, characterized by rising average temperatures and an increasing frequency of extreme heat days. Urban heat island effects are also a contributing factor.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of extreme heat days
Coastal
Calamvale is located inland and is not exposed to coastal hazards such as sea-level rise or storm surges.

What This Means for Property Owners
Insurance Outlook
Moderate increase in premiums possible due to flood and heatwave risks.
Price Impact
Potential for negative impact on property values in flood-prone areas or those highly exposed to heat stress.
Buyer Checklist
- 1.Review flood maps and stormwater drainage for the specific property.
- 2.Assess proximity to potential heat island effects (e.g., large paved areas).
- 3.Check insurance policy coverage and costs.
- 4.Verify bushfire preparedness for nearby vegetation.
- 5.Consider energy efficiency and cooling systems for heat resilience.
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 Calamvale's Climate Risk Profile
Calamvale, situated in the southern corridor of Brisbane, Queensland, presents a mixed climate risk profile for its residents. The suburb's topography and urban development patterns contribute to a moderate susceptibility to flooding, particularly during intense rainfall events. While not directly bordering major waterways, the network of local creeks and drainage systems can become overwhelmed, leading to overland flow and flash flooding in low-lying areas. The increasing intensity of rainfall, a projected consequence of climate change, exacerbates this risk, compounded by the growing amount of impervious surfaces from ongoing urbanisation.
The most significant climate-related threat to Calamvale is undoubtedly extreme heat. The region is experiencing a discernible rise in average temperatures, and the frequency and intensity of heatwaves are projected to increase. This poses substantial risks to public health, particularly for vulnerable populations, and places a strain on infrastructure, including energy grids. The urban heat island effect, where built environments retain more heat than natural landscapes, further intensifies these temperatures within the suburb.
In contrast, the risk of bushfire in Calamvale is relatively low. The suburb is not characterised by large tracts of dense bushland directly bordering residential areas. However, smaller pockets of vegetation, parks, and undeveloped land on the periphery can still pose a localised risk, especially during prolonged dry periods. The Queensland Fire and Emergency Services (QFES) designates areas based on proximity to flammable vegetation and historical fire activity.
Calamvale's inland location means it is entirely free from coastal hazards. There is no risk associated with sea-level rise, storm surges, or coastal erosion, which are concerns for many other coastal communities in Queensland. This absence of coastal risk is a significant mitigating factor in the suburb's overall climate resilience assessment.
Overall, residents of Calamvale should be aware of the increasing risks associated with flooding and extreme heat. While bushfire and coastal threats are minimal, proactive measures to manage stormwater and adapt to hotter conditions are crucial for maintaining the liveability and safety of the suburb.

Frequently Asked Questions
What is the main flood risk in Calamvale?
The main flood risk in Calamvale stems from localised overland flow and flash flooding caused by intense rainfall overwhelming the local creek systems and stormwater drainage. While not directly on a major river, low-lying areas can be affected.
How is Calamvale affected by heatwaves?
Calamvale faces a significant and increasing risk from heatwaves. Average temperatures are rising, and extreme heat days are becoming more frequent, exacerbated by the urban heat island effect from development.
Is Calamvale prone to bushfires?
The bushfire risk in Calamvale is generally low. There are no large, dense bushland areas directly adjacent to residential zones, although smaller vegetated areas can pose a minor risk during dry conditions.
Does sea-level rise affect Calamvale?
No, Calamvale is located inland and is not exposed to any risks associated with sea-level rise or coastal erosion.
What can I do to prepare my property in Calamvale for climate risks?
For flood risk, ensure your property's drainage is clear and consider flood resilience measures if in a known low-lying area. For heat, ensure good insulation, ventilation, and access to cooling. Maintain vegetation around your property to reduce minor bushfire risks.
Where can I find official flood maps for Calamvale?
Official flood maps for Calamvale can be found on the City of Brisbane's website under their 'Flooding and Stormwater' section.
What are the projected changes in rainfall for Calamvale?
Climate projections indicate an increase in the intensity of rainfall events for the Brisbane region, including Calamvale, which will heighten the risk of flash flooding and stormwater system strain.
