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

Detailed Hazard Analysis
heat Risk
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.
Primary Drivers
- ·Rising average temperatures
- ·Increased frequency of heatwaves
- ·Urban heat island effect
flood Risk
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.
Primary Drivers
- ·Increased rainfall intensity
- ·Sea level rise
- ·Urban development
coastal Risk
Mackay Harbour is vulnerable to coastal hazards such as sea level rise, storm surge, and coastal erosion. These hazards can damage infrastructure and property.
Primary Drivers
- ·Sea level rise
- ·Increased storm intensity
- ·Coastal erosion

What This Means for Property Owners
Insurance Outlook
Premiums are likely to increase due to flood and coastal risks.
Price Impact
Properties closer to the coast may experience price depreciation.
Buyer Checklist
- 1.Check flood maps and historical flood data.
- 2.Assess the property's vulnerability to sea level rise.
- 3.Inquire about council plans for coastal protection.
- 4.Consider the cost of insurance premiums.
How the region's climate is projected to change
Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.
Temperature
+0.5 to 1.1°C by 2030
Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.
Rainfall
Winter rain down up to 15% by 2030
The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.
Fire weather
Harsher, magnitude uncertain
High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.
Sea level
+0.12 m by 2030
At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

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.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
