Learn moreAbout Townsville's Climate Risk Profile
Townsville, located on the coast of North Queensland, is particularly vulnerable to the impacts of climate change. The city's location on the Ross River delta makes it susceptible to flooding from intense rainfall events, which are expected to become more frequent and severe due to climate change. Sea level rise also poses a threat to coastal areas, potentially impacting infrastructure and communities.
Heatwaves are another significant concern for Townsville. The city already experiences high temperatures and humidity during the summer months, and climate change is projected to increase the frequency and intensity of heatwaves. This could have serious health impacts, particularly for vulnerable populations such as the elderly and those with chronic health conditions.
Bushfire risk is moderate in Townsville, with areas of bushland surrounding the city posing a potential threat. Hot, dry conditions during the dry season can increase the risk of bushfires, which could damage property and threaten lives.
To address these challenges, Townsville City Council is implementing a range of adaptation measures, including upgrading drainage infrastructure, developing flood management plans, and promoting energy efficiency. Residents and businesses can also take steps to prepare for climate change by investing in flood-proofing measures, installing solar panels, and reducing their water consumption. Collective action is essential to building a more resilient and sustainable future for Townsville.
