Heat Risk Analysis
Collie in New South Wales faces elevated extreme heat risk. The Bureau of Meteorology (BOM) reports that Australia's average temperature has increased by approximately 1.5 °C since 1910, with the frequency of extreme heat days rising across most regions.
The urban heat island (UHI) effect can make built-up areas of Collie warmer than surrounding rural areas, particularly on summer nights. Dark roof materials, limited tree canopy cover, and heat-absorbing surfaces contribute to localised heat stress that varies by property.
Elderly and vulnerable residents should take precautions during heatwaves.
Get an address-level heat risk assessment from ClimateNest for Collie including cooling cost estimates, heatwave vulnerability scoring, and adaptation recommendations tailored to your property.
Climate projections show heat risk in Collie is tied to the broader Regional NSW climate. The suburb scores 6 on the 0–10 heat index, with the number of days above 35°C expected to grow through 2050 — a factor that affects cooling costs, garden viability and property desirability.
Collie located in Regional NSW (postcode 2827), is a New South Wales suburb tracked by ClimateNest. The suburb's median property value is $550,000, and understanding climate exposure is becoming a standard part of due diligence for buyers, lenders and insurers pricing property in Collie.
Across the six hazard axes ClimateNest models, the dominant climate risk in Collie is extreme heat (score 6/10), with moderate exposure. Insurance signals for the suburb point to premiums rising moderately (+25% by 2030). These suburb-level signals help prioritise which properties need the closest look — the actual risk of any single home can only be confirmed with an address-level report.
Whether you are buying, selling or renovating in Collie, extreme heat is the hazard to weigh first. Local council planning controls, state hazard mapping and lender climate policies each reference this kind of suburb-level signal, and property decisions in Collie are increasingly made with an address-level climate report in hand.

Frequently Asked Questions
How hot does Collie get in summer?
Collie in New South Wales experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near Collie. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in Collie?
Australia-wide, extreme heat events have become more frequent since the mid-20th century, and this trend is consistent with CSIRO climate projections for New South Wales. Continued warming is likely through 2050 under all emissions scenarios.
How does heat affect energy costs for Collie properties?
Higher temperatures increase cooling demand, which raises electricity costs. ClimateNest provides energy cost projections based on your property's specific exposure to extreme heat days in Collie and the performance of your building envelope.
What heat mitigation measures work best in Collie?
Effective heat mitigation includes light-coloured roofing (cool roofs), ceiling and wall insulation, double-glazed windows, external shading, cross-ventilation design, and increasing tree canopy around the property. These measures reduce indoor temperatures and cooling costs.
What are the main climate risks in Collie?
ClimateNest's suburb model rates Collie's dominant climate risk as extreme heat at 6/10 on a 0–10 index, followed by bushfire (5/10) and damaging wind (4/10). These are suburb-level averages — an address-level report is needed to confirm the risk of a specific property in Collie.
What share of Collie is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 16.4% of Collie in high-risk zones for bushfire, with a further 66.6% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
