Learn moreAbout New Norfolk's Climate Risk Profile
New Norfolk, Tasmania, is situated in a region that will experience the effects of climate change. The most significant risks are related to increased flooding due to its proximity to the Derwent River and projected increases in rainfall intensity. Higher temperatures and more frequent heatwaves also pose a threat, particularly to vulnerable populations.
Bushfire risk is present, although not as pronounced as flooding or heat. The surrounding region is susceptible to bushfires, and drier conditions could exacerbate this risk. Coastal risks are minimal due to the suburb's inland location.
Understanding these risks is crucial for residents and property owners in New Norfolk. Implementing adaptation measures and staying informed about climate projections can help mitigate potential impacts. The local council and state government provide resources and guidance for preparing for and responding to climate-related events.
Future climate projections indicate a likely increase in the severity of these risks. Planning and preparation are essential to ensure the community's resilience in the face of a changing climate. This includes investing in flood mitigation infrastructure, developing heatwave response plans, and promoting bushfire safety awareness.
