Historical Climate Events
A severe thunderstorm caused flash flooding and property damage in parts of Canberra, including areas near Bonner.
SourceThe 2003 Canberra bushfires caused widespread destruction and loss of life in the ACT. While Bonner was not directly impacted, the event highlighted the region's vulnerability to bushfires.
SourceCanberra experienced a prolonged heatwave in January 2017, with temperatures exceeding 40 degrees Celsius for several consecutive days.

Learn moreAbout bonner's Climate Risk Profile
Bonner, located in the Gungahlin district of the Australian Capital Territory, is a relatively new suburb that has seen rapid development in recent years. While it offers modern amenities and a family-friendly environment, Bonner is also exposed to several climate-related risks that are projected to intensify with climate change.
Flooding is a concern due to the suburb's topography and drainage infrastructure. Heavy rainfall events can lead to stormwater runoff and potential inundation of low-lying areas. Bushfire risk is also significant, given Bonner's proximity to grasslands and bushland. Hot, dry conditions and strong winds can create conditions conducive to bushfires, posing a threat to homes and properties.
Heatwaves are another growing concern, with average temperatures expected to rise in the coming decades. Vulnerable populations, such as the elderly and those with chronic health conditions, are particularly at risk during extreme heat events. The urban heat island effect can further amplify these risks, making it essential to implement strategies to mitigate heat exposure.
While Bonner is not directly exposed to coastal hazards, the broader impacts of climate change, such as disruptions to supply chains and increased insurance costs, could indirectly affect the suburb. Proactive adaptation measures, such as improving drainage infrastructure, implementing bushfire management strategies, and promoting energy efficiency, are crucial to building resilience and ensuring the long-term sustainability of Bonner.
