- Medium
- Flood
- Tweed Heads faces a notable risk of flooding due to its proximity to the Tweed River and low-lying areas. Increased rainfall intensity and rising sea levels are expected to exacerbate this risk.
- Bushfire
- Bushfire risk in Tweed Heads is relatively low compared to other regions, but still present due to surrounding bushland. Hotter, drier conditions could increase the likelihood of bushfires.
- Heat
- Tweed Heads is experiencing more frequent and intense heatwaves. Rising temperatures pose a risk to vulnerable populations and infrastructure.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2485
- Highest high-risk exposure
- 14.5% of land (bushfire)
Climate Safety Analysis
Tweed Heads in New South Wales 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 Tweed Heads'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 Tweed Heads 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 Tweed Heads including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Tweed Heads (postcode 2485) 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 (14.5% of land in high-risk zones), surface flood (8.8% of land in high-risk zones), riverine flood (7.6% of land in high-risk zones). Exposure is not uniform across Tweed Heads — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
