Learn moreAbout Westbury's Climate Risk Profile
Westbury, a suburb within the City of Ballarat, Victoria, presents a complex climate risk profile. The suburb is situated in a region prone to bushfires, with surrounding vegetation and historical weather patterns contributing to a significant risk score. This risk is projected to intensify in the coming decades due to climate change, leading to more frequent and severe fire weather conditions.
Flood risk in Westbury, while currently assessed as moderate, is influenced by local topography and proximity to waterways. Increased rainfall intensity, a predicted consequence of climate change, could exacerbate runoff and increase the likelihood of localized flooding events. While not directly exposed to coastal hazards, the broader regional climate shifts can indirectly impact Westbury through changes in weather patterns.
The suburb also experiences a moderate risk from heatwaves. Rising average temperatures and a greater frequency of extreme heat events pose a threat to public health and infrastructure. This trend is expected to continue, making heat adaptation a crucial consideration for residents and local authorities.
Looking ahead, climate projections for Westbury indicate an overall increase in climate-related risks. Both bushfire and heatwave risks are anticipated to grow, demanding strategic planning and community resilience efforts. While flood risk is also projected to increase, the absence of direct coastal exposure means that these are the primary hazards requiring focused attention.

Frequently Asked Questions
What is the primary bushfire risk for Westbury residents?
The primary bushfire risk stems from the proximity of residential areas to grasslands and bushland on the northern and eastern edges of the suburb. This, combined with increasing frequency of extreme fire weather, makes preparedness crucial.
How likely is flooding in Westbury?
Flood risk is considered moderate, mainly associated with intense rainfall events impacting areas near Yarrowee Creek. While not a widespread flood plain, localized inundation can occur.
What are the projected changes in heatwaves for Westbury?
Climate projections indicate an increase in both the frequency and intensity of heatwaves in Westbury, with more days exceeding 35°C and longer-lasting heat events.
Does Westbury face any sea-level rise risks?
No, Westbury is located significantly inland and is not exposed to any risks associated with sea-level rise or coastal erosion.
What can I do to make my property more resilient to climate risks in Westbury?
Focus on creating defendable space for bushfire risk, improving property drainage for flood risk, and enhancing home insulation and shading for heatwaves. Checking your insurance policy is also vital.
Where can I find official flood information for the City of Ballarat?
The City of Ballarat website provides flood maps and information on stormwater management, which are relevant for Westbury residents. You can typically find this under their planning and building sections.
