Hazard Breakdown
Climate Hazard Breakdown for The Gurdies
Flood
The Gurdies has a moderate flood risk, primarily due to its proximity to coastal waterways and low-lying areas. While not historically a major flood hotspot, increased rainfall intensity and potential storm surges pose a growing threat.
Key drivers:
- ·Storm surge
- ·Extreme rainfall
Bushfire
The Gurdies is situated within a significant bushfire-prone area, with extensive native vegetation surrounding the suburb. The risk is amplified by its location on the edge of the Bunurong Coastal Reserve and the potential for ember attack from nearby forests.
Key drivers:
- ·Vegetation type
- ·Drought conditions
Heat
The Gurdies experiences a moderate heat risk, with average January maximum temperatures in the mid-20s. However, the increasing frequency and intensity of heatwaves, coupled with limited urban cooling, elevate the risk of heat stress events.
Key drivers:
- ·Extreme heatwaves
- ·Urban heat island effect
Coastal
The Gurdies has a moderate coastal risk due to its proximity to the coast and exposure to potential sea-level rise and erosion. While not directly on the immediate coastline, storm surges and higher tides can impact low-lying areas.
Key drivers:
- ·Sea level rise
- ·Coastal erosion
Wind
Moderate wind risk — cold fronts and gusty winds
Storm
Moderate storm risk — severe thunderstorms
Social
Moderate social stability
Energy

Historical Climate Events
The Black Saturday bushfires impacted areas across Victoria, including regions near The Gurdies. While direct destruction in The Gurdies was limited, the event heightened awareness and preparedness in the region.
SourceSignificant rainfall across Victoria led to localized flooding in low-lying areas, including some coastal regions near The Gurdies. Minor inundation was reported in some properties.
SourceA prolonged heatwave affected Victoria, with temperatures in the high 30s and low 40s. The Gurdies experienced several days of extreme heat, posing risks to residents and increasing bushfire danger.
SourceSeveral grass and bushfires occurred in the region due to dry conditions. While no major fires threatened The Gurdies directly, the increased fire activity served as a reminder of the ongoing risk.

Projections based on CSIRO and BOM climate modelling. Scenario: RCP 4.5
| Hazard | Today | 2030 | 2050 |
|---|---|---|---|
| flood | 40 | 4.5(+0.5) | 5.5(+1.5) |
| bushfire | 70 | 7.7(+0.7) | 9.0(+2.0) |
| heat | 60 | 6.6(+0.6) | 8.2(+2.2) |
| coastal | 50 | 5.4(+0.4) | 6.8(+1.8) |
By 2030, under a moderate emissions scenario (RCP 4.5), The Gurdies is projected to see a noticeable increase in overall climate risk. Bushfire and heat risks are expected to rise most significantly, with more frequent extreme heat days and increased fire danger ratings. Flood and coastal risks will also see a moderate increase due to more intense rainfall and higher sea levels.

Learn moreAbout The Gurdies's Climate Risk Profile
The Gurdies, a semi-rural locality in Victoria, presents a complex climate risk profile for its residents. The most pressing concern is the high bushfire risk, stemming from its location adjacent to significant areas of native bushland, including parts of the Bunurong Coastal Reserve. The combination of dry sclerophyll forests, prevailing winds, and the increasing likelihood of prolonged dry spells creates conditions ripe for intense bushfires, with ember attack being a significant threat to properties.
Flood risk in The Gurdies is moderate but warrants attention. While the suburb is not typically associated with major riverine flooding, its low-lying coastal proximity means it is susceptible to inundation from storm surges, king tides, and extreme rainfall events that can overwhelm local drainage systems. The increasing intensity of rainfall predicted for the region exacerbates this risk, potentially leading to localized flooding.
Heatwaves are another growing concern for The Gurdies. While the average summer temperatures are generally pleasant, the frequency and severity of extreme heat events are projected to increase. This poses a risk to vulnerable populations and can strain local infrastructure. The lack of extensive urban canopy in some areas can also contribute to localized heat build-up.
Coastal processes, including sea-level rise and erosion, present a long-term but escalating risk. Although not directly on the immediate coastline, The Gurdies' proximity means that higher sea levels will amplify the impact of storm surges and potentially lead to increased coastal erosion in adjacent areas, indirectly affecting the suburb.
Given these risks, residents and the local council are encouraged to focus on robust emergency preparedness, vegetation management, and infrastructure resilience. Understanding the specific hazards and implementing appropriate adaptation strategies will be key to safeguarding the community.

Frequently Asked Questions
What is the main bushfire risk for The Gurdies?
The main bushfire risk for The Gurdies comes from its proximity to significant areas of native bushland, including the Bunurong Coastal Reserve. The dry sclerophyll forests and prevailing winds create conditions for intense fires, with ember attack being a major concern.
How susceptible is The Gurdies to flooding?
The Gurdies has a moderate flood risk, primarily due to its low-lying coastal location. It is susceptible to inundation from storm surges, king tides, and extreme rainfall events that can overwhelm local drainage systems.
Are there specific bushfire overlays affecting properties in The Gurdies?
Yes, properties in The Gurdies are generally located within a Bushfire Prone Area overlay, as designated by the Victorian Government and local council. This means specific building regulations and planning requirements apply.
What are the projected changes in heatwaves for The Gurdies?
Climate projections indicate an increase in the frequency and intensity of heatwaves for The Gurdies. This means more days exceeding 35°C and potentially longer periods of extreme heat, increasing the risk of heat stress.
What can I do to prepare my property for bushfires in The Gurdies?
Key preparation steps include maintaining a defendable space around your home (clearing vegetation), upgrading building materials to resist fire, having a well-practiced bushfire survival plan, and staying informed about fire danger ratings and warnings from the CFA.
Does sea-level rise pose a risk to The Gurdies?
While The Gurdies is not directly on the coast, sea-level rise increases the impact of storm surges and higher tides. This can lead to greater inundation risk in low-lying areas and potential coastal erosion in nearby areas, indirectly affecting the suburb.
