Hazard Breakdown
Climate Hazard Breakdown for Mackay
Flood
Mackay is prone to flooding due to its location near the Pioneer River and susceptibility to heavy rainfall events. Climate change is expected to increase the intensity of rainfall, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
While not as significant as flooding, Mackay faces some bushfire risk, particularly in areas bordering bushland. Drier conditions and higher temperatures could increase this risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Mackay already experiences high temperatures, and climate change is projected to increase the frequency and intensity of heatwaves, posing a risk to vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
As a coastal city, Mackay is vulnerable to sea level rise and coastal erosion. Climate change is expected to worsen these impacts, threatening infrastructure and coastal ecosystems.
Key drivers:
- ·Sea level rise
- ·Increased storm surge
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 Mackay's Climate Risk Profile
Mackay, located on the central Queensland coast, is particularly vulnerable to the impacts of climate change. The city's proximity to the Pioneer River and the coast makes it susceptible to flooding from heavy rainfall and sea level rise. Rising temperatures and more frequent heatwaves pose a significant threat to public health, especially for vulnerable populations.
The increasing intensity of rainfall events is a major concern for Mackay. The city has a history of flooding, and climate change is projected to increase the frequency and severity of these events. This could lead to damage to property, disruption of infrastructure, and potential loss of life.
Sea level rise is another significant threat to Mackay. As the sea level rises, coastal erosion will become more severe, and storm surges will reach further inland. This could damage coastal infrastructure, inundate low-lying areas, and threaten coastal ecosystems.
The increasing frequency and intensity of heatwaves also pose a serious risk to Mackay. High temperatures can lead to heatstroke, dehydration, and other health problems, particularly for the elderly, children, and people with chronic illnesses. The urban heat island effect can further exacerbate these risks in densely populated areas.
Addressing these climate risks will require a coordinated effort from all levels of government, as well as the community. This includes investing in infrastructure to reduce flood risk, implementing measures to protect coastal areas, and developing strategies to mitigate the impacts of heatwaves. It also requires raising awareness of climate risks and empowering individuals and businesses to take action to adapt to these changing conditions.
