Hazard Breakdown
Climate Hazard Breakdown for Lucas Heights
Flood
Lucas Heights faces a moderate risk of flooding, primarily from heavy rainfall events and potential overflow from local waterways. The risk is projected to increase slightly due to climate change.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Lucas Heights has a high bushfire risk due to its proximity to extensive bushland areas. Hot, dry conditions and strong winds can exacerbate the risk during the bushfire season. Climate change is expected to further increase the frequency and intensity of bushfires.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Lucas Heights experiences a moderate risk from heatwaves, with increasing average temperatures and more frequent heat stress events projected. Vulnerable populations, such as the elderly, are particularly at risk.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Lucas Heights has a low risk from coastal hazards due to its inland location. Sea level rise and coastal erosion are not significant threats to this suburb.
Key drivers:
- ·Distance from the coast
Wind
Moderate wind risk — East Coast Lows and gust fronts
Storm
Moderate storm risk — severe thunderstorms and hail
Social
Moderate social stability — mixed urban density
Energy
Moderate energy costs — climate-driven cooling demand

Learn moreAbout Lucas Heights's Climate Risk Profile
Lucas Heights, located in the Sutherland Shire, is a suburb with a unique blend of residential areas and proximity to significant bushland. This proximity contributes to a heightened risk of bushfires, particularly during the dry summer months. Climate change projections indicate an increase in the frequency and intensity of bushfires, posing a growing threat to the community.
Flooding is another concern for Lucas Heights, primarily due to heavy rainfall events and potential overflow from local waterways. While the risk is currently moderate, climate change is expected to increase rainfall intensity, potentially leading to more frequent and severe flooding. Effective stormwater management and flood mitigation measures are crucial for protecting properties and infrastructure.
Heatwaves are also becoming more frequent and intense in Lucas Heights, posing a risk to vulnerable populations such as the elderly and those with chronic health conditions. Rising average temperatures and more frequent heat stress events can lead to heatstroke and other heat-related illnesses. Residents should take precautions to stay cool and hydrated during heatwaves.
Coastal risks are minimal in Lucas Heights due to its inland location. Sea level rise and coastal erosion are not significant threats to the suburb. However, the community should still be aware of the potential impacts of climate change on the broader region and support efforts to mitigate greenhouse gas emissions.
