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 Trafalgar South
Flood
Trafalgar South faces a medium to high risk of flooding, primarily due to its proximity to waterways and low-lying areas. Heavy rainfall events can overwhelm local drainage systems and lead to inundation.
Key drivers:
- ·Increased intensity of rainfall events
- ·Urbanisation and increased impervious surfaces
Bushfire
The suburb has a moderate bushfire risk, influenced by surrounding rural areas and vegetation. While not directly on the urban fringe of major bushland, ember attack and proximity to grasslands pose a threat.
Key drivers:
- ·Warmer and drier conditions leading to increased fuel load dryness
- ·Expansion of residential areas into peri-urban interfaces
Heat
Trafalgar South is exposed to significant heat stress, with a high number of days exceeding 35°C projected. The urban form and lack of extensive tree canopy in some areas contribute to the urban heat island effect.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency and intensity of heatwaves
Coastal
Trafalgar South is located inland and has no direct exposure to coastal hazards such as sea-level rise or storm surges.

Detailed Hazard Analysis
heat Risk
Trafalgar South is exposed to significant heat stress, with a high number of days exceeding 35°C projected. The urban form and lack of extensive tree canopy in some areas contribute to the urban heat island effect.
Primary Drivers
- ·Rising average temperatures
- ·Increased frequency and intensity of heatwaves
- ·Urban development reducing green space
flood Risk
Trafalgar South faces a medium to high risk of flooding, primarily due to its proximity to waterways and low-lying areas. Heavy rainfall events can overwhelm local drainage systems and lead to inundation.
Primary Drivers
- ·Increased intensity of rainfall events
- ·Urbanisation and increased impervious surfaces
- ·Potential for riverine flooding from nearby Latrobe River tributaries
coastal Risk
Trafalgar South is located inland and has no direct exposure to coastal hazards such as sea-level rise or storm surges.
Data sourcebushfire Risk
The suburb has a moderate bushfire risk, influenced by surrounding rural areas and vegetation. While not directly on the urban fringe of major bushland, ember attack and proximity to grasslands pose a threat.
Primary Drivers
- ·Warmer and drier conditions leading to increased fuel load dryness
- ·Expansion of residential areas into peri-urban interfaces
- ·Prevailing wind patterns during fire events
What This Means for Property Owners
Insurance Outlook
Increasing premiums and potential for higher excess due to flood and bushfire risks.
Price Impact
Potential for negative impact on property values in higher-risk flood zones. Heat stress may also become a factor.
Buyer Checklist
- 1.Review flood maps and historical flood data for the specific property.
- 2.Check bushfire attack level (BAL) rating for the property.
- 3.Assess proximity to waterways and drainage infrastructure.
- 4.Investigate local tree canopy cover and potential for urban heat island effect.
- 5.Inquire about existing flood mitigation measures on the property.
- 6.Understand local council's emergency management and climate adaptation plans.
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 Trafalgar South's Climate Risk Profile
Trafalgar South, situated within the Baw Baw Shire, presents a mixed climate risk profile for its residents. The suburb experiences a medium overall climate risk, largely driven by significant threats from flooding and extreme heat.
The flood risk is primarily associated with its location in a relatively low-lying area and proximity to tributaries of the Latrobe River. Increased rainfall intensity, a common projection under climate change scenarios, can exacerbate existing drainage issues and lead to inundation, particularly during severe weather events. While not a coastal suburb, the potential for flash flooding and riverine flooding requires careful consideration for property development and existing infrastructure.
Heatwaves pose another substantial challenge. Trafalgar South is projected to experience a growing number of days with extreme temperatures, contributing to heat stress for residents and increased demand on energy resources. The urban form, with varying degrees of green space and tree canopy, can influence local temperature variations, potentially creating urban heat island effects during hot periods.
Bushfire risk, while moderate, is a persistent concern for peri-urban areas like Trafalgar South. The surrounding rural landscape and grasslands mean that the suburb is susceptible to ember attack and the spread of fire from nearby vegetated areas. Preparedness and adherence to fire safety regulations are crucial, especially during the hotter, drier months.
In contrast, Trafalgar South is not exposed to coastal hazards such as sea-level rise or storm surges, given its inland location. This significantly mitigates risks associated with coastal erosion or inundation that affect other parts of Victoria.
Overall, residents and stakeholders in Trafalgar South should focus on building resilience against flooding and extreme heat, while maintaining vigilance regarding bushfire threats. Understanding these risks and implementing appropriate adaptation measures is key to ensuring the long-term safety and liveability of the suburb.

Frequently Asked Questions
What is the main flood risk for Trafalgar South?
The main flood risk for Trafalgar South stems from heavy rainfall events overwhelming local drainage systems and potential flooding from nearby tributaries of the Latrobe River. Low-lying areas are particularly susceptible.
How will climate change affect heatwaves in Trafalgar South?
Climate change is projected to increase the frequency, intensity, and duration of heatwaves in Trafalgar South, leading to more days above 35°C and a greater risk of heat stress.
Is Trafalgar South prone to bushfires?
Yes, Trafalgar South is classified as a bushfire-prone area. While not directly adjacent to dense forests, it is surrounded by rural land and grasslands that can pose a significant bushfire risk, especially during hot and dry conditions.
What are the projected changes in rainfall patterns for Trafalgar South?
Projections suggest an increase in the intensity of rainfall events for Trafalgar South, meaning that while total annual rainfall might not change drastically, extreme downpours are expected to become more common, increasing flood risk.
Does Trafalgar South face any coastal erosion or sea-level rise risks?
No, Trafalgar South is located inland and is not exposed to any risks associated with sea-level rise, storm surges, or coastal erosion.
What can I do to protect my property from flooding in Trafalgar South?
Consider property-level flood resilience measures such as raising electrical appliances, installing flood barriers, improving drainage around your home, and ensuring your home's design accounts for potential inundation. Check with Baw Baw Shire Council for specific local guidance.
