Flood
Bass has a medium risk of flooding, primarily from localised heavy rainfall events and potential overland flow paths. While not directly on a major river, the low-lying nature of some areas and proximity to smaller creeks contribute to this risk.
Key drivers:
- ·Increased intensity of rainfall events
- ·Urbanisation leading to increased runoff
Bushfire
Bass is situated in a high bushfire risk area, with significant surrounding vegetation and a history of fire events. The risk is amplified during hot, dry, and windy conditions.
Key drivers:
- ·Longer and more intense fire seasons
- ·Increased fuel loads
Heat
Bass experiences a medium risk from heatwaves, with a notable increase in the frequency and intensity of extreme heat days. This is exacerbated by its rural setting and potential for heat island effects in built-up areas.
Key drivers:
- ·Rising average temperatures
- ·More frequent and severe heatwaves
Coastal
Bass has a very low risk of coastal hazards, being located inland from the immediate coastline. While sea level rise is a statewide concern, its direct impact on Bass is minimal.
Key drivers:
- ·Minimal direct exposure to coastal erosion
- ·Significant distance from the sea

Detailed Hazard Analysis
heat Risk
Bass experiences a medium risk from heatwaves, with a notable increase in the frequency and intensity of extreme heat days. This is exacerbated by its rural setting and potential for heat island effects in built-up areas.
Primary Drivers
- ·Rising average temperatures
- ·More frequent and severe heatwaves
- ·Reduced diurnal temperature variation
flood Risk
Bass has a medium risk of flooding, primarily from localised heavy rainfall events and potential overland flow paths. While not directly on a major river, the low-lying nature of some areas and proximity to smaller creeks contribute to this risk.
Primary Drivers
- ·Increased intensity of rainfall events
- ·Urbanisation leading to increased runoff
- ·Changes in land use
coastal Risk
Bass has a very low risk of coastal hazards, being located inland from the immediate coastline. While sea level rise is a statewide concern, its direct impact on Bass is minimal.
Primary Drivers
- ·Minimal direct exposure to coastal erosion
- ·Significant distance from the sea
bushfire Risk
Bass is situated in a high bushfire risk area, with significant surrounding vegetation and a history of fire events. The risk is amplified during hot, dry, and windy conditions.
Primary Drivers
- ·Longer and more intense fire seasons
- ·Increased fuel loads
- ·Drier vegetation conditions
What This Means for Property Owners
Insurance Outlook
Moderate to High premiums expected due to bushfire risk. Flood insurance may be necessary in specific low-lying areas.
Price Impact
Potential negative impact on property values in high-risk zones, particularly for bushfire-prone areas. Increased demand for resilient properties.
Buyer Checklist
- 1.Review CFA bushfire risk maps
- 2.Check council flood overlay maps
- 3.Assess property's bushfire attack level (BAL)
- 4.Inquire about past flood events
- 5.Verify emergency access routes
- 6.Consider proximity to vegetation
- 7.Check insurance availability and cost
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 Bass's Climate Risk Profile
Bass, located within the Bass Coast Shire in Victoria, is a rural township with a growing population. Its geographical setting presents a mixed climate risk profile, with bushfire being the most prominent concern. The surrounding natural landscape, while beautiful, also contributes to a heightened risk during the fire season, necessitating vigilance and preparedness from residents and authorities.
The township experiences moderate risks associated with flooding, primarily driven by intense rainfall events that can overwhelm local drainage systems and create overland flow paths. While Bass is not situated on a major river system, the topography and land use patterns can exacerbate localised flooding, particularly in lower-lying areas. The increasing intensity of rainfall due to climate change suggests this risk may grow over time.
Heatwaves are another growing concern for Bass. As average temperatures rise and the frequency of extreme heat days increases, the community faces greater risks of heat-related illnesses and increased strain on infrastructure. The rural nature of the area means that heat island effects might be less pronounced than in major cities, but the lack of widespread cooling infrastructure can still pose challenges during prolonged heat events.
Coastal hazards, such as sea-level rise and coastal erosion, represent a minimal risk for Bass itself. The suburb is situated a considerable distance inland from the coast, significantly mitigating direct exposure to these phenomena. However, broader coastal management strategies in the region remain important for the overall resilience of the Bass Coast Shire.
Given these risks, Bass is increasingly focusing on climate adaptation and resilience. This includes enhancing bushfire preparedness, improving stormwater management, and developing strategies to cope with extreme heat. Community engagement and robust local governance are key to ensuring the long-term safety and sustainability of Bass in the face of a changing climate.

Frequently Asked Questions
What is the main bushfire risk for Bass residents?
The main bushfire risk stems from the surrounding grasslands and bushland, which can ignite and spread rapidly during hot, dry, and windy conditions. Residents should consult the CFA website for specific risk ratings and preparedness advice.
How likely is flooding in Bass?
Flooding in Bass is typically localised and associated with intense rainfall events causing overland flows. While not a major riverine flood risk, certain low-lying areas may be more susceptible. Check the Bass Coast Shire Council planning maps for specific flood overlays.
Will climate change make Bass hotter?
Yes, climate change projections indicate that Bass, like the rest of Victoria, will experience hotter summers with more frequent and intense heatwaves. This increases the risk of heat-related illnesses and strain on infrastructure.
Does Bass face any sea level rise risk?
Bass is located a significant distance inland from the coast, so direct risks from sea level rise and coastal erosion are considered very low. Broader coastal management in the region is still important, however.
What should I do to prepare my property for bushfire season in Bass?
Key preparations include creating defendable space around your home, having a well-practiced bushfire survival plan, ensuring adequate water supplies, and staying informed about fire danger ratings through the CFA.
Where can I find official flood information for Bass?
Official flood information, including flood maps and planning overlays, can be found on the Bass Coast Shire Council's website under their planning and environment sections.
