Hazard Breakdown
Climate Hazard Breakdown for Maryborough
Flood
Maryborough is located on the Mary River and has a history of flooding. Climate change is expected to increase the frequency and intensity of heavy rainfall events, leading to a higher risk of riverine and flash flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise affecting river flow
Bushfire
While not immediately surrounded by dense bushland, Maryborough has some exposure to bushfire risk, particularly in areas with vegetation. Drier conditions and higher temperatures due to climate change can increase the likelihood of bushfires.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Maryborough experiences hot summers, and climate change is projected to increase the frequency and intensity of heatwaves. This poses a risk to vulnerable populations and infrastructure.
Key drivers:
- ·Increased greenhouse gas emissions
- ·Urban heat island effect
Coastal
Located inland, Maryborough's coastal risk is primarily related to the Mary River's connection to the coast. Sea level rise can exacerbate flooding during storm surges and high tides, impacting low-lying areas along the river.
Key drivers:
- ·Sea level rise
- ·Increased storm surge intensity
Wind
Notable wind risk — tropical cyclone wind fields
Storm
Notable storm risk — cyclones and thunderstorms
Social
Moderate social stability — growth regions
Energy
Elevated energy costs — high cooling demand

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 exacerbate these risks, with more intense rainfall and rising sea levels increasing the likelihood of both riverine and flash flooding. The local council and residents need to be proactive in implementing adaptation measures to mitigate these impacts.
Bushfire risk is also a concern, although not as immediate as flooding. Drier conditions and higher temperatures can increase the flammability of vegetation, posing a threat to properties on the outskirts of town. Vigilance and proper land management are crucial for minimizing this risk.
Heatwaves are becoming more frequent and intense, posing a significant health risk, especially to vulnerable populations such as the elderly and those with pre-existing health conditions. Ensuring access to cooling centers and promoting heat-safe practices are essential.
While Maryborough is not directly on the coast, its proximity to the Mary River means that sea level rise can impact the town through increased flooding during storm surges and high tides. Protecting riverbanks and implementing coastal management strategies are important for long-term resilience.
