About Harristown's Climate Risk Profile

Harristown, located in the Toowoomba region of Queensland, is subject to a range of climate-related risks. The most significant of these is flooding, due to its location within a flood-prone area and the potential for increased rainfall intensity as a result of climate change. Historical flood events have impacted the region, and future events could pose a threat to property and infrastructure.

Heatwaves are another significant concern for Harristown. As temperatures rise, the risk of heat stress and heatstroke increases, particularly for vulnerable populations such as the elderly and those with pre-existing health conditions. The urban environment can also amplify the effects of heat, creating urban heat islands.

Bushfire risk is relatively lower compared to other parts of Queensland, but it is still a factor to consider, especially during dry periods. While Harristown is not directly on the coast, the impacts of climate change are still relevant, particularly in terms of extreme weather events.

Residents and property owners in Harristown should take steps to prepare for these risks, including developing emergency plans, maintaining their properties, and staying informed about weather forecasts and warnings. Local authorities are also working to mitigate the impacts of climate change through infrastructure improvements and community awareness programs.
