Historical Climate Events
The 2003 Canberra bushfires had a devastating impact on the region, including Bonython, causing significant property damage and loss of life.
SourceA prolonged heatwave in January 2018 resulted in record-breaking temperatures and increased demand for emergency services.
SourceHeavy rainfall in late 2022 led to localized flooding in parts of Bonython, causing damage to property and infrastructure.

Projections based on CSIRO and BOM climate modelling. Scenario: RCP8.5
| Hazard | Today | 2030 | 2050 |
|---|---|---|---|
| flood | 4.5 | 4.8(+0.3) | 5.0(+0.5) |
| bushfire | 6.0 | 6.2(+0.2) | 6.3(+0.3) |
| heat | 5.0 | 5.8(+0.8) | 6.5(+1.5) |
| coastal | 1.0 | 1.0 | 1.0 |
By 2030, Bonython is projected to experience a moderate increase in overall climate risk, driven primarily by more frequent and intense heatwaves. Flood risk may also increase due to changes in rainfall patterns.

Learn moreAbout bonython's Climate Risk Profile
Bonython, located in the Australian Capital Territory, is subject to a range of climate-related risks. The suburb's proximity to bushland increases its vulnerability to bushfires, especially during dry and windy conditions. Additionally, heavy rainfall events can lead to flooding, particularly in low-lying areas or those with inadequate stormwater drainage.
Rising temperatures and more frequent heatwaves pose a significant threat to the health and well-being of Bonython residents, particularly the elderly and those with pre-existing health conditions. The urban heat island effect can further amplify these impacts, leading to higher nighttime temperatures and increased energy demand for cooling.
While Bonython is not directly exposed to coastal hazards, the broader impacts of climate change, such as disruptions to supply chains and increased migration, could indirectly affect the suburb. It is crucial for residents and local authorities to take proactive measures to mitigate these risks and adapt to the changing climate.
Addressing these challenges requires a multi-faceted approach, including improved bushfire management practices, enhanced stormwater infrastructure, and strategies to reduce the urban heat island effect. Community awareness and preparedness are also essential for minimizing the impacts of climate-related events.
