About St Andrews's Climate Risk Profile

St Andrews, located in the Campbelltown region of New South Wales, is subject to a range of climate-related risks. The primary concerns are flooding due to increased rainfall intensity and heatwaves resulting from rising temperatures. Bushfire risk is also a factor due to the presence of surrounding bushland.

The area's flood risk is amplified by its proximity to local waterways and low-lying topography. Intense rainfall events can overwhelm drainage systems, leading to property damage and disruption to infrastructure. Climate change projections indicate an increase in the frequency and severity of such events.

Heatwaves pose a significant threat to the health and well-being of residents, especially vulnerable populations. The urban heat island effect can further exacerbate temperatures in built-up areas. Planning for cooler spaces and ensuring access to cooling during extreme heat events is crucial.

While coastal risks are minimal, the community should remain informed about broader climate trends and adaptation strategies. Taking proactive measures to mitigate risks and build resilience is essential for ensuring the long-term sustainability of St Andrews.
