Hazard Breakdown
Climate Hazard Breakdown for Casuarina
Flood
Casuarina faces a moderate risk of flooding, primarily due to its low-lying coastal location and proximity to waterways. Intense rainfall events can lead to stormwater runoff exceeding drainage capacity.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The risk of bushfire in Casuarina is relatively low compared to other regions, but still present due to surrounding vegetation. Dry conditions and strong winds can increase the potential for fire spread.
Key drivers:
- ·Dry vegetation
- ·Wind patterns
Heat
Casuarina experiences high temperatures and humidity, leading to significant heat stress during the summer months. Climate change is expected to exacerbate these conditions, increasing the frequency and intensity of heatwaves.
Key drivers:
- ·Rising average temperatures
- ·Increased humidity
Coastal
As a coastal suburb, Casuarina is vulnerable to the impacts of sea level rise and coastal erosion. Storm surges and king tides can inundate low-lying areas, damaging infrastructure and property.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity
Wind
Notable wind risk — tropical cyclone winds
Storm
Notable storm risk — cyclones and monsoonal storms
Social
Moderate social stability — remote communities
Energy
Elevated energy costs — year-round cooling

Learn moreAbout Casuarina's Climate Risk Profile
Casuarina, located in the Northern Territory, is a coastal suburb that is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from intense rainfall and storm surges, heat stress due to rising temperatures, and coastal erosion from sea level rise.
The suburb's low-lying topography and proximity to the coast make it particularly susceptible to flooding. Climate change is projected to increase the intensity of rainfall events, leading to more frequent and severe flooding. Sea level rise will further exacerbate this risk by increasing the extent of inundation during storm surges and high tides.
Rising temperatures pose a significant threat to the health and well-being of Casuarina residents. The frequency and intensity of heatwaves are expected to increase, leading to higher rates of heat stress and heatstroke, particularly among vulnerable populations. The urban heat island effect can further amplify these impacts.
Coastal erosion is another growing concern for Casuarina. Sea level rise is already causing erosion of beaches and foreshores, threatening coastal infrastructure and property. Increased storm intensity can accelerate this process, leading to further loss of land and damage to coastal assets.
Addressing these climate risks will require a combination of adaptation and mitigation measures. Adaptation strategies include improving drainage infrastructure, implementing coastal protection measures, and developing heat action plans. Mitigation efforts focus on reducing greenhouse gas emissions to slow the pace of climate change.
