Is Port Hacking, NSW Climate Safe? 2026 Assessment
Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Port Hacking faces a moderate risk of flooding due to its proximity to the Port Hacking waterway and low-lying areas. Intense rainfall events can lead to stormwater runoff and riverine flooding.
- Bushfire
- The suburb has a moderate bushfire risk due to the presence of surrounding bushland. Hot, dry conditions and strong winds can increase the likelihood of bushfires.
- Heat
- Port Hacking is susceptible to heatwaves, particularly during the summer months. Rising temperatures can pose health risks to vulnerable populations.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2229
- Highest high-risk exposure
- 9% of land (bushfire)
Climate Safety Analysis
Port Hacking 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 Port Hacking'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 Port Hacking 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 Port Hacking including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Port Hacking (postcode 2229) 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 (9% of land in high-risk zones), surface flood (8.6% of land in high-risk zones), riverine flood (3.9% of land in high-risk zones). Exposure is not uniform across Port Hacking — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
