About Hollisdale's Climate Risk Profile

Hollisdale is a suburb in New South Wales that is exposed to a range of climate-related risks. The primary concerns are flooding and bushfires, which are expected to become more frequent and intense due to climate change.

Flooding is a significant risk due to the proximity of waterways and low-lying areas. Intense rainfall events can lead to riverine and flash flooding, impacting properties and infrastructure. Bushfires pose a high risk due to the surrounding bushland. Hot, dry conditions and strong winds can exacerbate the risk of bushfires, threatening lives and properties.

Heat risk is also increasing, with rising average temperatures and more frequent heatwave events projected in the future. This can lead to heat stress and other health impacts, particularly for vulnerable populations. Coastal risks are relatively low due to the suburb's inland location.

Residents and property owners should take steps to prepare for these risks, including developing emergency plans, maintaining properties, and staying informed about weather conditions and warnings. Local authorities are working to implement adaptation measures to reduce the impacts of climate change.
