Learn moreAbout Tiwi's Climate Risk Profile
Tiwi, located in the Northern Territory, is susceptible to a range of climate-related risks. The suburb's low-lying coastal location increases its vulnerability to flooding from intense rainfall events and storm surges. Sea level rise further exacerbates this risk, potentially leading to inundation of coastal areas and damage to infrastructure.
Heat is another significant concern for Tiwi. The region already experiences high temperatures and humidity, and climate change is expected to worsen these conditions. This can lead to heat stress, particularly for vulnerable populations such as the elderly and those with pre-existing health conditions.
While the bushfire risk in Tiwi is relatively lower compared to other regions, it is still a factor to consider. Dry conditions during the dry season can increase the risk of bushfires, which can pose a threat to property and human life.
Adapting to these climate risks will require a multi-faceted approach, including investments in infrastructure improvements, community awareness campaigns, and emergency preparedness planning. By taking proactive measures, Tiwi can enhance its resilience to the impacts of climate change.
