Hazard Breakdown
Climate Hazard Breakdown for Mackay Harbour
Flood
Mackay Harbour faces a notable risk of flooding due to its low-lying coastal location and proximity to waterways. Intense rainfall events can lead to riverine and flash flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The risk of bushfire in Mackay Harbour is relatively low due to the suburb's coastal location and limited vegetation. However, dry conditions and strong winds can increase the risk.
Key drivers:
- ·Dry vegetation
- ·Strong winds
Heat
Mackay Harbour experiences high temperatures and humidity during summer, leading to heat stress. Climate change is expected to increase the frequency and intensity of heatwaves.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Mackay Harbour is vulnerable to coastal hazards such as sea level rise, storm surge, and coastal erosion. These hazards can damage infrastructure and property.
Key drivers:
- ·Sea level rise
- ·Increased storm 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 Mackay Harbour's Climate Risk Profile
Mackay Harbour is a coastal suburb in Queensland that is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from heavy rainfall and storm surges, heatwaves during the summer months, and coastal erosion due to sea level rise.
The risk of flooding is exacerbated by the suburb's low-lying topography and proximity to waterways. Intense rainfall events can overwhelm drainage systems and cause widespread inundation. Sea level rise is also increasing the risk of coastal flooding and erosion.
Heatwaves are becoming more frequent and intense, posing a significant health risk to vulnerable populations. The urban heat island effect can further amplify temperatures in built-up areas.
Coastal erosion is a long-term threat to Mackay Harbour, with sea level rise gradually eroding beaches and foreshores. This can damage infrastructure and property, and reduce the amenity of coastal areas.
Addressing these climate risks requires a combination of adaptation and mitigation measures. Adaptation measures include improving drainage infrastructure, building seawalls, and implementing heatwave early warning systems. Mitigation measures include reducing greenhouse gas emissions to slow the pace of climate change.
