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 St Clair
Flood
Low to moderate flood risk, primarily associated with minor creek overflow during extreme rainfall events.
Key drivers:
- ·Minor creek inundation
- ·Urban stormwater capacity
Bushfire
Low bushfire risk due to distance from major bushland areas and urbanisation.
Key drivers:
- ·Proximity to scattered vegetation
- ·Fuel load management
Heat
High heat risk due to urban heat island effect and limited tree canopy.
Key drivers:
- ·Urban heat island effect
- ·Reduced green space
Coastal
Negligible coastal risk due to significant distance from the coast.

What This Means for Property Owners
Insurance Outlook
Stable, but increasing premiums possible for flood cover in specific low-lying pockets.
Price Impact
Currently minimal, but potential for future impact due to increasing heat stress and minor flood risks.
Buyer Checklist
- 1.Check proximity to Kororoit Creek and potential overland flow paths.
- 2.Assess tree canopy cover and shading around the property.
- 3.Review local stormwater infrastructure and maintenance.
- 4.Inquire about past heatwave experiences and property 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 St Clair's Climate Risk Profile
St Clair, located within the City of Brimbank in Victoria, presents a mixed climate risk profile. The suburb's overall rating is 'Medium', largely influenced by a 'High' score in heat risk. This is attributed to the urban heat island effect, a common characteristic of established suburban areas with significant impervious surfaces and limited tree canopy. The density of housing and infrastructure contributes to higher ambient temperatures, particularly during summer months, exacerbating the impact of heatwaves.
The flood risk in St Clair is assessed as 'Low to Moderate'. While not situated in a major floodplain, the suburb is susceptible to localised flooding from minor creeks and overwhelmed stormwater systems during intense rainfall events. The topography and the extent of urban development play a role in how effectively rainfall is managed, with potential for flash flooding in low-lying areas or those with inadequate drainage infrastructure.
Bushfire risk is considered 'Low' for St Clair. The suburb is predominantly urbanised, with limited direct adjacency to large, high-risk bushland areas. While some scattered vegetation exists, and ember attack can be a concern in any Australian setting, the immediate threat level is significantly lower compared to areas bordering national parks or extensive forests. Fire management strategies by local authorities and the Country Fire Authority (CFA) focus on maintaining defensible space where applicable.
Coastal risks are negligible for St Clair. The suburb is located a considerable distance inland from the Victorian coastline, rendering it immune to direct impacts from sea-level rise, storm surges, or coastal erosion. This geographical advantage significantly mitigates any climate-related risks associated with coastal processes.
Looking ahead, climate projections suggest an intensification of existing risks, particularly concerning heat. The frequency and severity of heatwaves are expected to increase, placing greater strain on infrastructure and public health. While flood and bushfire risks are projected to remain relatively stable, adaptation measures focusing on heat resilience will be crucial for the long-term liveability and safety of St Clair residents.

Frequently Asked Questions
What is the main climate risk for St Clair residents?
The primary climate risk for St Clair is heat, driven by the urban heat island effect and limited green space. This means the suburb can get significantly hotter than surrounding areas during heatwaves.
Is St Clair at risk of major flooding?
St Clair has a low to moderate flood risk. While not prone to major riverine flooding, localised flooding can occur during intense rainfall events due to the capacity of the urban stormwater system and proximity to minor creeks like Kororoit Creek.
What can I do to make my property more resilient to heat in St Clair?
Consider planting shade trees, installing awnings or pergolas, improving insulation, using light-coloured roofing materials, and ensuring adequate ventilation. Staying hydrated and seeking cool refuges during heatwaves is also crucial.
Does St Clair face any bushfire threats?
The bushfire risk in St Clair is low due to its urban nature. However, ember attack from nearby vegetation can still pose a risk, so maintaining defensible space around your property and having a basic bushfire plan is advisable.
How will climate change affect St Clair in the future?
Climate projections indicate that heatwaves will become more frequent and intense in St Clair by 2050. There may also be slight increases in the risk of localised flooding during extreme rainfall events.
Where can I find more information about climate risks in Brimbank?
The City of Brimbank council website provides information on climate change strategies and local environmental initiatives. For broader climate data and projections, the Bureau of Meteorology (BOM) and CSIRO websites are valuable resources.
