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 Rosanna
Flood
Rosanna faces a moderate to high risk of flash flooding and riverine inundation due to its proximity to the Yarra River and its tributaries, coupled with low-lying areas.
Key drivers:
- ·Increased rainfall intensity
- ·Urbanisation and impervious surfaces
Bushfire
While not directly bordering major bushland, Rosanna has some proximity to vegetated areas and parks, posing a low to moderate bushfire risk, particularly during extreme weather events.
Key drivers:
- ·Proximity to parklands
- ·Dry vegetation conditions
Heat
Rosanna experiences significant heat stress due to its urban environment, limited tree canopy in some areas, and a high number of heatwave events.
Key drivers:
- ·Urban Heat Island effect
- ·Increased frequency and intensity of heatwaves
Coastal
Rosanna is located inland and is not directly exposed to coastal erosion or sea-level rise risks.

What This Means for Property Owners
Insurance Outlook
Premiums may increase for properties in known flood zones or those with higher bushfire risk ratings. Heat-related damage is also a growing concern.
Price Impact
Properties with demonstrated resilience to heat and flood may command a premium. Conversely, properties in high-risk areas could see reduced demand or price stagnation.
Buyer Checklist
- 1.Review flood maps and historical flood data for the specific property.
- 2.Assess proximity to waterways and drainage systems.
- 3.Check for adequate tree canopy and shading around the property.
- 4.Understand local bushfire risk and preparedness measures.
- 5.Inquire about existing flood mitigation or cooling strategies.
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 Rosanna's Climate Risk Profile
Rosanna, situated in Melbourne's inner northeast, presents a mixed climate risk profile for its residents. The suburb's overall rating is 'Medium', reflecting a combination of significant heat and flood vulnerabilities, balanced by lower risks from bushfire and coastal impacts.
The most pressing concern for Rosanna is the increasing intensity and frequency of heatwaves. As an established urban area, it experiences the Urban Heat Island effect, where built environments absorb and retain more heat. This is exacerbated by a variable distribution of tree canopy and green spaces, leading to higher ambient temperatures during summer months. Projections indicate a substantial increase in heat stress events, impacting public health and infrastructure.
Flood risk is another significant factor for Rosanna. The suburb lies within the catchment of the Yarra River and its tributaries, with some areas being low-lying. While major flood events are infrequent, flash flooding from intense rainfall and potential overflow from the Yarra pose a tangible threat to properties and infrastructure. The increasing intensity of rainfall events due to climate change amplifies this risk.
Bushfire risk in Rosanna is comparatively lower than in outer-lying suburbs. However, the presence of local parks and vegetated corridors means that the risk, though moderate, cannot be entirely dismissed, especially during prolonged dry periods and high fire danger days. Preparedness remains important for properties bordering these green spaces.
Coastal risks are negligible for Rosanna, given its inland location, far removed from the direct impacts of sea-level rise and coastal erosion. This aspect of climate risk does not pose a direct threat to the suburb.
Overall, Rosanna requires a focused approach to climate adaptation, prioritising heat resilience strategies and robust flood mitigation measures. Community awareness and preparedness for extreme weather events are key to ensuring the long-term safety and liveability of the suburb.

Frequently Asked Questions
What is the main flood risk in Rosanna?
The main flood risk in Rosanna stems from its proximity to the Yarra River and its tributaries, as well as the potential for flash flooding due to intense rainfall overwhelming stormwater systems in low-lying areas.
How will climate change affect heatwaves in Rosanna?
Climate change is projected to increase the frequency, intensity, and duration of heatwaves in Rosanna, leading to more frequent days of extreme heat and greater risk of heat-related illnesses.
Is Rosanna prone to bushfires?
Rosanna has a low to moderate bushfire risk. While not directly adjacent to large tracts of dense bushland, properties near local parks and vegetated areas should remain vigilant during high fire danger periods.
What can I do to protect my property from flooding in Rosanna?
Consider installing flood barriers, ensuring stormwater drains are clear, elevating essential services, and checking your home insurance policy. For properties near the Yarra, consult Banyule Council's flood information.
Are there specific areas in Rosanna more affected by heat?
Areas with less tree canopy cover and a higher density of buildings and paved surfaces tend to experience higher temperatures due to the Urban Heat Island effect. Newer developments may have less established shade.
Where can I find official flood information for Rosanna?
Official flood information, including flood maps for Rosanna, can be found on the Banyule City Council website and through the Victorian State Emergency Service (SES).
