Climate Safety Score
5.5Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Idalia faces a moderate risk of flooding due to its proximity to the Ross River and other waterways. Climate change is expected to increase rainfall intensity, potentially leading to more frequent and severe flood events.
- Bushfire
- The risk of bushfire in Idalia is moderate, with some areas bordering bushland. Hotter and drier conditions due to climate change may increase the frequency and intensity of bushfires.
- Heat
- Idalia experiences high temperatures, particularly during the summer months. 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
- 4811
Climate Safety Analysis
Idalia 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 Idalia's climate safety include heat, flood. 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 Idalia 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 Idalia 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 Idalia. An address-level check is what tells you about a specific property before you buy, sell or insure it.
Local Hazard Evidence
Historical Events
The Townsville floods of 2019 caused widespread damage in Idalia, with many homes inundated by floodwaters. The Ross River Dam was at capacity and released large volumes of water.
Townsville experienced a prolonged heatwave in early 2018, with temperatures exceeding 35°C for several consecutive days. This put a strain on the electricity grid and caused health problems for vulnerable residents.
Heavy rainfall caused flooding in parts of Idalia, with some roads and properties affected.

Frequently Asked Questions
Is Idalia safe from climate change?
No location in Australia is entirely immune to climate change impacts. Idalia has an overall Medium climate risk rating. Understanding the specific hazards at your property address — not just the suburb average — provides the most reliable risk picture.
Which climate hazard poses the biggest risk in Idalia?
The dominant hazard for Idalia depends on geography and local environment. Proximity to waterways elevates flood risk, while proximity to bushland increases bushfire risk. ClimateNest's multi-hazard analysis identifies the highest-risk hazards for any specific address.
How does Idalia compare to nearby suburbs for climate safety?
Nearby suburbs may have different climate risk profiles depending on elevation, vegetation cover, drainage patterns, and land use. ClimateNest allows comparison of climate safety scores across Queensland suburbs.
Should I be concerned about buying property in Idalia?
Climate risk should be one factor in your decision, alongside price, location, and amenity. An informed buyer understands the specific risks at a property address and factors insurance costs and climate projections into their assessment of long-term value.
What climate projections should I know for Idalia?
Key projections for Queensland from CSIRO include increased average temperatures, more frequent hot days, changes in rainfall seasonality, longer fire seasons, and potential increases in extreme rainfall intensity. These trends inform the long-term outlook for Idalia.
