Hazard Breakdown
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.
Wind
Moderate wind risk — cold fronts and gusty winds
Storm
Moderate storm risk — severe thunderstorms
Social
Moderate social stability
Energy
Moderate energy costs — heating and cooling needs

Historical Climate Events
Significant rainfall led to localized flooding in low-lying areas around Trafalgar South, impacting some roads and properties.
SourceA grassfire threatened nearby rural properties and required significant firefighting resources, highlighting the bushfire risk in the region.
SourceA prolonged heatwave affected Victoria, with temperatures exceeding 40°C in many areas, including the Gippsland region, leading to health alerts and increased fire danger.
SourceWidespread flooding across Victoria, including areas near Trafalgar South, due to La Niña conditions causing extreme rainfall and river level rises.

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.
