Is Tiwi, NT Climate Safe? 2026 Assessment
Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Tiwi faces a moderate risk of flooding, primarily due to its low-lying coastal location and proximity to waterways. Intense rainfall events can lead to stormwater runoff and riverine flooding.
- Bushfire
- The bushfire risk in Tiwi is relatively low compared to other regions, but still present. The presence of vegetation and dry conditions during the dry season can contribute to fire risk.
- Heat
- Tiwi experiences a high heat risk due to its tropical climate. Rising temperatures and increased humidity can lead to heat stress, particularly during the wet season.
- Storm
- Notable storm risk — tropical cyclones and monsoonal storms
- Postcode
- 0810
- Highest high-risk exposure
- 20.4% of land (bushfire)
Climate Safety Analysis
Tiwi in Northern Territory 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 Tiwi'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 Tiwi 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 Tiwi including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Tiwi (postcode 0810) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are bushfire (20.4% of land in high-risk zones), tropical cyclone (9.8% of land in high-risk zones), extreme wind (9.1% of land in high-risk zones). Exposure is not uniform across Tiwi — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Frequently Asked Questions
Is Tiwi safe from climate change?
No location in Australia is entirely immune to climate change impacts. Tiwi 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 Tiwi?
The dominant hazard for Tiwi 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 Tiwi 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 Northern Territory suburbs.
Should I be concerned about buying property in Tiwi?
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 Tiwi?
Key projections for Northern Territory 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 Tiwi.
What share of Tiwi is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 20.4% of Tiwi in high-risk zones for bushfire, with a further 66% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
