Climate Safety Score
5.8Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Lake Illawarra is at significant risk of flooding due to its low-lying topography and proximity to Lake Illawarra and surrounding waterways. Increased rainfall intensity and rising sea levels are expected to exacerbate this risk.
- Bushfire
- Lake Illawarra faces a moderate bushfire risk due to the presence of nearby bushland. Hot, dry conditions and strong winds can increase the likelihood of bushfires spreading to residential areas.
- Heat
- Lake Illawarra is likely to experience more frequent and intense heatwaves in the future. This can pose a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
