Historical Climate Events
The Black Saturday bushfires significantly impacted the broader Gippsland region, with numerous properties lost and extensive areas of forest burned. While Rawson itself may have been spared direct major destruction, the surrounding areas experienced severe fire activity, highlighting the inherent risk.
SourceSignificant rainfall across Victoria led to localised flooding in many areas, including parts of Gippsland. While specific details for Rawson are limited, regional reports indicate disruptions due to heavy downpours and potential creek overflows.
SourceThe summer of 2019-2020 saw extensive bushfire activity across eastern Victoria, including the 'Gippsland Fires'. While the main fires were further east, the conditions and proximity posed a significant threat and required heightened vigilance in areas like Rawson.
SourceWidespread heavy rainfall across Victoria in late 2022 caused significant flooding. Regional reports indicate impacts in Gippsland, with potential for localised flooding events affecting communities like Rawson due to saturated catchments and intense downpours.
SourceClimate Outlook to 2050
Projections based on CSIRO and BOM climate modelling. Scenario: RCP 4.5
| Hazard | Today | 2030 | 2050 |
|---|---|---|---|
| flood | 40 | 4.2(+0.2) | 4.5(+0.5) |
| bushfire | 70 | 7.3(+0.3) | 8.0(+1.0) |
| heat | 60 | 6.4(+0.4) | 7.2(+1.2) |
| coastal | 0 | 0.0 | 0.0 |
By 2030, under a moderate emissions scenario (RCP 4.5), Rawson is projected to see a slight increase in overall climate risk. Bushfire risk is expected to rise due to hotter, drier conditions, while heatwave frequency and intensity will also increase. Localised flood risk may see a minor uptick due to more intense rainfall events.

Learn moreAbout Rawson's Climate Risk Profile
Rawson, nestled in Victoria's Gippsland region, is a community with a distinct relationship with its natural environment, which unfortunately includes significant climate-related risks. The most prominent concern for residents is the high risk of bushfire. Situated adjacent to extensive native forests and grasslands, Rawson falls within a designated bushfire-prone area. The increasing frequency and intensity of heatwaves, coupled with drier fuel loads predicted under future climate scenarios, elevate the potential for severe fire events. This necessitates robust preparedness measures and ongoing vigilance from both residents and local authorities.
Beyond bushfire, Rawson also contends with risks associated with flooding and extreme heat. While not directly on a major river, the suburb's topography and proximity to smaller waterways mean that intense rainfall events can lead to localised flooding and inundation. Climate change projections suggest an increase in the intensity of such rainfall, potentially exacerbating these flood risks. Furthermore, like much of regional Victoria, Rawson is expected to experience rising average temperatures and a greater number of extreme heat days. This poses health risks, particularly to vulnerable populations, and increases the strain on local infrastructure and energy resources.
Fortunately, Rawson is not directly impacted by coastal hazards such as sea-level rise or storm surges, given its inland location. This removes a significant layer of climate risk that affects many other Australian communities. However, the absence of coastal threats does not diminish the importance of addressing the bushfire, flood, and heat risks that are pertinent to the suburb's unique geographical context.
Understanding these risks is crucial for the long-term sustainability and liveability of Rawson. Property owners and the local council must work collaboratively to implement effective adaptation and mitigation strategies. This includes adhering to building regulations in bushfire-prone areas, maintaining defensible space around properties, improving local drainage systems, and promoting community awareness and preparedness for all climate-related emergencies. The future resilience of Rawson depends on proactive planning and a commitment to adapting to a changing climate.

Frequently Asked Questions
What is the main climate risk for Rawson residents?
The primary climate risk for Rawson is bushfire, due to its location adjacent to significant bushland areas and its designation as a bushfire-prone area. Projections indicate an increasing risk due to hotter and drier conditions.
Does Rawson experience flooding?
Yes, Rawson can experience localised flooding, particularly during periods of intense rainfall. While not prone to major riverine flooding, the terrain and proximity to smaller waterways mean overland flow and creek overflow are potential risks that are projected to increase with more extreme rainfall events.
How will climate change affect temperatures in Rawson?
Climate change is projected to increase average temperatures in Rawson, leading to more frequent and intense heatwaves. This poses risks to health, infrastructure, and increases the likelihood of conditions conducive to bushfires.
What should I do to prepare my property in Rawson for bushfire?
It is crucial to prepare your property by maintaining a defendable space around your home, clearing gutters and roofs of debris, ensuring adequate water supplies, and having a well-rehearsed emergency plan. Using fire-resistant building materials is also highly recommended.
Is Rawson affected by sea-level rise?
No, Rawson is located inland and is not exposed to risks associated with sea-level rise or coastal erosion. Its climate risks are primarily related to bushfire, heat, and localised flooding.
Where can I find official information about climate risks in Rawson?
Official information can be found through the Gippsland Shire Council website, the Country Fire Authority (CFA) for bushfire information, the Bureau of Meteorology (BOM) for climate data, and the Victorian State Emergency Service (SES) for emergency preparedness.
