Key Facts
- Climate Safety
- Medium
- 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.
- 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.
- 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.
- Storm
- Notable storm risk — tropical cyclones and severe thunderstorms in summer months
- Postcode
- 4740
- Region
- Mackay Region
- Median property value
- $550,000
- Dominant hazard
- extreme heat
Climate Safety Analysis
Mackay in Queensland has an overall climate safety rating of Medium. This multi-hazard assessment combines flood, bushfire, heat, coastal, and storm risk data with climate projections to 2050 from CSIRO and the Bureau of Meteorology.
Key factors affecting Mackay's climate safety include heat, flood, coastal. Each hazard is assessed independently and combined for an overall picture. Australia has warmed by approximately 1.5 °C since 1910, with flow-on effects to fire weather, extreme rainfall, and heatwave frequency.
Climate safety for property in Mackay is not uniform — it varies by address. Factors such as elevation, distance to waterways, proximity to bushland, and local drainage all influence actual risk at a specific property. Two nearby properties can have materially different risk profiles.
For a complete property-specific climate safety report for Mackay including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
