About Tanilba Bay's Climate Risk Profile

Tanilba Bay, situated on the Tilligerry Peninsula in Port Stephens, New South Wales, is exposed to a range of climate-related hazards. Its low-lying coastal location makes it particularly vulnerable to flooding from heavy rainfall, storm surges, and sea level rise. The increasing frequency and intensity of extreme weather events, driven by climate change, pose a significant threat to the suburb's infrastructure and residential areas.

Bushfire risk is also a concern, although less immediate than flooding. The presence of surrounding vegetation means that Tanilba Bay is susceptible to ember attacks during periods of high fire danger. Residents should maintain their properties to reduce fuel loads and be prepared to evacuate if necessary.

Heatwaves are another growing threat, with rising temperatures expected to exacerbate the risk of heat stress, particularly among vulnerable populations such as the elderly and those with pre-existing health conditions. Access to cooling centers and community awareness programs are essential to mitigate the impacts of extreme heat.

Coastal erosion and inundation are long-term challenges for Tanilba Bay. Sea level rise is gradually eroding shorelines and increasing the risk of coastal flooding during storms. Protecting coastal ecosystems and implementing coastal management strategies are crucial to preserving the suburb's natural environment and safeguarding properties.
