Overall Risk Score

Address-level

Hazard Breakdown

Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.

Climate Hazard Breakdown for Cassilis

Flood

Cassilis faces a moderate risk of flooding due to its proximity to the Munmurra River and associated creeks. Intense rainfall events can cause these waterways to overflow, impacting low-lying areas within the suburb.

Key drivers:

  • ·Increased rainfall intensity
  • ·Changes in land use

Bushfire

Cassilis is located in a region with a high bushfire risk. The surrounding bushland creates a significant fuel load, and dry conditions coupled with strong winds can lead to rapid fire spread.

Key drivers:

  • ·Increased frequency of heatwaves
  • ·Drier vegetation

Heat

Cassilis experiences moderately high temperatures during summer, with the potential for heatwaves. Climate change is expected to increase the frequency and intensity of heat events, posing a risk to vulnerable populations.

Key drivers:

  • ·Rising global temperatures
  • ·Urban heat island effect

Coastal

Cassilis is located inland and does not face any direct coastal risks such as sea level rise or coastal erosion.

  • 3.Obtain insurance quotes and understand coverage limitations.
  • 4.Consider the potential impact of climate change on property value.

How the region's climate is projected to change

Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.

Temperature

+0.5 to 1.1°C by 2030

Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.

Rainfall

Winter rain down up to 15% by 2030

The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.

Fire weather

Harsher, magnitude uncertain

High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.

Sea level

+0.12 m by 2030

At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

About Cassilis's Climate Risk Profile

Cassilis, NSW, is a small town situated in a region susceptible to various climate-related hazards. The primary concerns for Cassilis are flooding from the Munmurra River and surrounding creeks, bushfire risk due to the extensive surrounding bushland, and increasing heatwave frequency and intensity.

The risk of flooding is driven by intense rainfall events that can cause the Munmurra River to overflow. Climate change projections suggest an increase in extreme rainfall events, which could lead to more frequent and severe flooding in Cassilis. This poses a threat to properties located near the river and low-lying areas.

Bushfire risk is also a significant concern for Cassilis. The surrounding bushland provides ample fuel for fires, and dry conditions coupled with strong winds can create dangerous fire conditions. Climate change is expected to increase the frequency and severity of bushfires in the region, potentially impacting homes and infrastructure.

Heatwaves are another growing concern for Cassilis. The town experiences high temperatures during summer, and climate change is projected to increase the frequency and intensity of heatwaves. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.

While Cassilis does not face direct coastal risks, the impacts of climate change on other regions could indirectly affect the town through economic disruptions and population displacement. It is important for residents and local authorities to take proactive measures to adapt to the changing climate and mitigate the risks posed by these hazards.
