About Oak Flats's Climate Risk Profile

Oak Flats, located in the Shellharbour region of New South Wales, is exposed to a range of climate-related risks. Its proximity to Lake Illawarra and the coast makes it particularly vulnerable to flooding and coastal hazards. Rising sea levels and increased storm intensity are expected to exacerbate these risks in the coming decades.

Heatwaves are another significant concern for Oak Flats. The suburb experiences high temperatures during summer, and climate change is projected to increase the frequency and intensity of heatwaves. This poses a threat to vulnerable populations, such as the elderly and those with chronic health conditions.

While not immediately adjacent to dense bushland, Oak Flats has some exposure to bushfire risk. Embers can travel long distances, posing a threat even to properties not directly bordering bushland. Dry vegetation and increased frequency of heatwaves can increase the risk of bushfires.

The Shellharbour City Council is working to address climate change risks through various initiatives, including coastal management plans and stormwater management upgrades. However, individual residents also need to take steps to prepare for and adapt to the changing climate. This includes measures such as improving home insulation, installing rainwater tanks, and developing emergency plans.
