Learn moreAbout Maryborough's Climate Risk Profile
Maryborough, Queensland, is situated on the Mary River and has a history of significant flood events. Climate change is projected to increase the intensity and frequency of heavy rainfall, leading to a higher risk of both riverine and flash flooding. The rising sea levels can also affect the river's flow, exacerbating flood risks in low-lying areas.
Bushfire risk in Maryborough is moderate but increasing. While the immediate surroundings are not heavily forested, hotter and drier conditions can increase the flammability of vegetation, especially during prolonged drought periods. Residents should stay informed about bushfire risks and maintain their properties accordingly.
Heatwaves are a growing concern for Maryborough. The town already experiences hot summers, and climate change is expected to make these conditions more extreme. This poses a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions. Public health initiatives and community awareness are crucial for mitigating the impacts of heatwaves.
Although Maryborough is not directly on the coast, its proximity to the Mary River means it is indirectly affected by coastal hazards. Sea level rise and storm surges can increase the risk of flooding along the river, particularly in areas close to the river mouth. Planning and infrastructure development should consider these coastal influences.
Addressing these climate risks requires a multi-faceted approach, including investments in flood mitigation infrastructure, bushfire prevention measures, and public health programs to protect against heatwaves. Community engagement and awareness are also essential for building resilience to climate change.
