Climate Safety Analysis
South Johnstone, located in Queensland, faces a combination of climate hazards that together shape its overall climate safety profile. This multi-hazard assessment considers flood, bushfire, extreme heat, coastal, and severe storm risks — each evaluated independently and combined into an overall perspective.
Australia's climate is changing. The Bureau of Meteorology and CSIRO report that the continent has warmed by approximately 1.5 °C since 1910, with increased frequency of extreme heat events, longer fire seasons in southern and eastern Australia, and changes to rainfall patterns across many regions. These trends provide important context for evaluating climate safety in suburbs like South Johnstone.
Climate safety for property in South Johnstone is not uniform — it varies by address. Factors such as elevation, distance to waterways, proximity to bushland, urban heat island intensity, and local drainage all influence the actual risk at a specific property. A property on higher ground with cleared surrounds will have a different risk profile to one at the bottom of a slope adjacent to dense vegetation.
Use ClimateNest to generate a comprehensive, address-level climate safety report for any property in South Johnstone covering all major hazards with projections to 2050, insurance outlook, and adaptation recommendations.
South Johnstone (postcode 4859) 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 (12.4% of land in high-risk zones), extreme wind (9.7% of land in high-risk zones), riverine flood (8.9% of land in high-risk zones). Exposure is not uniform across South Johnstone — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
