Climate Safety Analysis

Jilliby 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 Jilliby's climate safety include 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 Jilliby 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 Jilliby including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.

Jilliby (postcode 2259) 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 (9.5% of land in high-risk zones), surface flood (8.8% of land in high-risk zones), riverine flood (8.7% of land in high-risk zones). Exposure is not uniform across Jilliby — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
