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

What This Means for Property Owners

Insurance Outlook

Insurance premiums may increase in areas at high risk of flooding or coastal erosion.

Price Impact

Properties in vulnerable areas may experience a decrease in value.

Buyer Checklist

  • 1.Check flood maps and historical flood data.
  • 2.Assess the property's vulnerability to coastal erosion.
  • 3.Consider the potential impact of heatwaves on energy costs.
  • 4.Inquire about insurance coverage and 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.

About 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.

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