West Wollongong (postcode 2500) 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 (7.8% of land in high-risk zones), riverine flood (7.1% of land in high-risk zones), surface flood (6.8% of land in high-risk zones).
