Climate Safety Score
5.8Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- 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.
- 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.
- 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.
- Storm
- Notable storm risk — tropical cyclones and severe thunderstorms in summer months

Climate Safety Analysis
Mackay Harbour 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 Harbour'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 Harbour 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 Harbour including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
ClimateNest assesses hazards at the address rather than the suburb, because exposure varies street by street within Mackay Harbour. An address-level check is what tells you about a specific property before you buy, sell or insure it.
