Climate Hazard Breakdown for Sunbury
Flood
Sunbury faces a moderate risk of flooding due to its proximity to the Jackson's Creek and other waterways. Climate change is expected to increase rainfall intensity, potentially worsening flood events.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Sunbury has a moderate bushfire risk due to surrounding grasslands and bushland areas. Hot, dry conditions during summer increase the likelihood of bushfires.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Sunbury is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, especially during summer.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Sunbury is located inland and does not face any direct coastal risks.

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 Sunbury's Climate Risk Profile
Sunbury, located in Victoria, is susceptible to several climate-related risks. The primary concerns are flooding due to its proximity to Jackson's Creek, and the increasing frequency and intensity of heatwaves. Bushfire risk is also a factor, given the surrounding grasslands and bushland.
Flooding events are expected to become more severe as climate change leads to increased rainfall intensity. This could impact residential areas and infrastructure near the creek. Heatwaves pose a significant threat to vulnerable populations, especially the elderly and those with pre-existing health conditions.
The bushfire risk is influenced by dry vegetation and high temperatures during the summer months. While not as immediate a threat as flooding or heatwaves, it remains a concern that requires ongoing vigilance and mitigation efforts.
Overall, Sunbury needs to focus on adaptation strategies to mitigate the impacts of climate change. This includes improving flood defenses, implementing heatwave management plans, and managing bushfire risks through controlled burns and community education.
