About Freemans Reach's Climate Risk Profile

Freemans Reach, located in the Hawkesbury region of New South Wales, is increasingly vulnerable to the impacts of climate change. The suburb's location on the Hawkesbury River floodplain makes it particularly susceptible to flooding, which is expected to worsen with increased rainfall intensity and frequency.

Rising temperatures and more frequent heatwaves pose a significant threat to the health and well-being of residents, especially the elderly and those with pre-existing health conditions. The risk of bushfires is also increasing due to hotter, drier conditions.

While Freemans Reach is not directly exposed to coastal hazards, the broader impacts of climate change, such as disruptions to supply chains and infrastructure, could still affect the community. It is crucial for residents and local authorities to take proactive measures to adapt to these changing conditions.

Preparing for more frequent and intense extreme weather events, such as floods and heatwaves, is essential. This includes developing emergency plans, investing in infrastructure improvements, and promoting community awareness of climate risks.
