Tilligerry Creek (postcode 2319) 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 surface flood (12.2% of land in high-risk zones), bushfire (11.4% of land in high-risk zones), riverine flood (7.1% of land in high-risk zones). Exposure is not uniform across Tilligerry Creek — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
