The bushfire risk in Noarlunga is relatively low compared to other areas in South Australia, but still present due to nearby vegetation. Hotter, drier conditions are projected to increase this risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Noarlunga experiences a high heat risk, with increasing average temperatures and more frequent heatwave events projected. This poses a significant threat to vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Noarlunga has a moderate coastal risk due to its proximity to the coast. Sea level rise and coastal erosion are potential threats, particularly to low-lying areas.
Key drivers:
- ·Sea level rise
- ·Coastal erosion
Wind
Moderate wind risk — gusty northerly winds
Storm
Moderate storm risk — occasional thunderstorms
Social
Moderate social stability
Energy
Moderate energy costs — summer cooling

Learn moreAbout Noarlunga's Climate Risk Profile
Noarlunga, located in South Australia, is projected to experience increasing climate risks in the coming decades. The primary concerns are rising temperatures, more frequent heatwaves, and increased flooding potential. Sea level rise and coastal erosion also pose a threat, although less severe than heat and flooding.
The risk of flooding is driven by the Onkaparinga River and the potential for intense rainfall events. Climate change is expected to increase the frequency and intensity of these events, leading to higher flood risks for properties near the river and in low-lying areas. Effective flood management strategies are crucial to mitigate these risks.
Heatwaves are becoming more frequent and intense, posing a significant threat to public health, especially for vulnerable populations such as the elderly and those with pre-existing health conditions. Urban planning and building design should prioritize heat mitigation strategies to reduce the impact of extreme heat.
While the bushfire risk is relatively lower compared to other regions, it is still a concern, particularly in areas adjacent to bushland. Maintaining vegetation and implementing bushfire prevention measures are essential to minimize the risk of bushfires.
Addressing these climate risks requires a coordinated effort from local government, residents, and businesses. Implementing adaptation measures, such as improving drainage infrastructure, promoting water conservation, and enhancing community resilience, will be crucial to ensure a sustainable future for Noarlunga.
