Flood
Low to moderate flood risk, primarily from localised heavy rainfall and potential minor inundation from nearby waterways.
Key drivers:
- ·Heavy rainfall events
- ·Urbanisation increasing runoff
Bushfire
Moderate to high bushfire risk due to proximity to significant bushland areas and vegetation types common in Victoria.
Key drivers:
- ·Increased fuel loads
- ·Warmer, drier conditions
Heat
Moderate heat risk, with increasing frequency and intensity of heatwaves projected.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of extreme heat days
Coastal
Low coastal risk due to distance from the immediate coastline, but potential for storm surge impacts during extreme weather.

What This Means for Property Owners
Insurance Outlook
Moderate. Bushfire risk may lead to higher premiums or specific policy conditions.
Price Impact
Potential for negative impact on resale value in high-risk zones, particularly for bushfire-prone properties.
Buyer Checklist
- 1.Review bushfire attack level (BAL) rating for the property.
- 2.Check proximity to vegetation and potential fuel sources.
- 3.Understand local flood mapping and drainage.
- 4.Assess property's heat resilience (e.g., insulation, shading).
- 5.Verify emergency service access routes.
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 Coronet Bay's Climate Risk Profile
Coronet Bay, located in Victoria's Bass Coast Shire, presents a mixed climate risk profile for residents. The most significant concern is the moderate to high risk of bushfire, stemming from its location adjacent to substantial areas of native vegetation and its susceptibility to dry, windy conditions typical of the region. While not in an immediate high-risk zone, the potential for ember attack and the proximity of fuel sources necessitate vigilant preparation.
Flood risk in Coronet Bay is generally considered low to moderate. The primary concern relates to localised flooding from intense rainfall events, which can overwhelm drainage systems, particularly in lower-lying areas. While major riverine flooding is unlikely, flash flooding can pose a threat during severe storms. Proximity to minor waterways also contributes to this risk profile.
Heatwaves are an increasing concern across Victoria, and Coronet Bay is no exception. The suburb experiences a moderate risk associated with extreme heat, with projections indicating a rise in the frequency and intensity of heatwave events. This poses risks to vulnerable populations, infrastructure, and local ecosystems. The lack of significant urban heat island effect mitigates this risk somewhat compared to more densely populated areas.
Coastal risks for Coronet Bay are minimal due to its inland position relative to the Bass Strait coastline. While direct inundation from sea-level rise or storm surges is unlikely, extreme weather events could potentially lead to indirect impacts through amplified rainfall or wind effects. The primary coastal influence is the general weather patterns originating from the coast.
Overall, residents of Coronet Bay should prioritise bushfire preparedness, maintain awareness of localised flood risks, and take precautions during heatwave events. While the suburb is not currently facing extreme climate threats, the projected trends suggest a gradual increase in risk across all categories, underscoring the importance of ongoing adaptation and preparedness.

Frequently Asked Questions
What is the main climate risk for Coronet Bay?
The primary climate risk for Coronet Bay is bushfire, due to its proximity to significant bushland areas. Flood and heat risks are also present but generally considered lower.
Is Coronet Bay prone to flooding?
Coronet Bay has a low to moderate risk of localised flooding, mainly from heavy rainfall overwhelming drainage systems. It is not typically affected by major riverine flooding.
How will climate change affect Coronet Bay by 2050?
By 2050, under a moderate emissions scenario, Coronet Bay is projected to experience increased bushfire risk and more frequent heatwaves. Flood and coastal risks are expected to rise slightly.
What should I do to prepare for bushfires in Coronet Bay?
Develop a Bushfire Survival Plan, keep your property clear of excess vegetation (defensible space), and stay informed about fire danger ratings and warnings from the CFA.
Does Coronet Bay have a high risk of sea-level rise impacts?
No, Coronet Bay has a low risk of direct sea-level rise impacts as it is located several kilometres inland from the coast.
Where can I find the official flood map for Coronet Bay?
You can find flood information and maps relevant to Coronet Bay on the Bass Coast Shire Council's website, often within their planning scheme or specific flood studies.
Are there specific building requirements for bushfire-prone areas in Coronet Bay?
Yes, properties in designated bushfire-prone areas, including Coronet Bay, must comply with specific building regulations outlined in the Victorian Building Regulations, often related to bushfire attack level (BAL) ratings.
