Learn moreAbout Longreach's Climate Risk Profile
Longreach, located in central Queensland, is particularly vulnerable to heatwaves due to its inland location and high average temperatures. The risk of heatwaves is projected to increase significantly with climate change, posing a threat to public health, especially for vulnerable populations.
Flooding is another concern for Longreach, as the town is situated near the Thomson River. Heavy rainfall events in the river's catchment area can lead to riverine flooding, impacting properties and infrastructure. While flood mitigation measures are in place, the risk remains a factor for residents to consider.
Bushfire risk is moderate, with surrounding grasslands and vegetation posing a potential fire hazard during the dry season. Hot, dry conditions and strong winds can increase the likelihood of bushfires spreading rapidly. Residents should maintain their properties and be aware of fire safety guidelines.
Coastal risks are negligible due to Longreach's inland location. However, the broader impacts of climate change, such as disruptions to supply chains and economic activity, could indirectly affect the town.
Adapting to these climate risks is crucial for Longreach. This includes implementing heatwave action plans, improving flood defenses, and promoting bushfire preparedness. Community awareness and proactive measures are essential to building resilience in the face of a changing climate.
