Collie

Collie is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

Collie's population is approximately 9,465 as of November 2025. This figure represents an increase of 653 people, a rise of 7.4% since the 2021 Census which reported a population of 8,812. The change is inferred from ABS's estimated resident population of 9,408 in June 2024 and additional validated new addresses since the Census date. This results in a population density ratio of 5.5 persons per square kilometer. Collie's growth rate of 7.4% since the census is within 1.5 percentage points of the national average of 8.9%, indicating strong fundamentals for growth. Population growth was primarily driven by interstate migration, contributing approximately 48.8% of overall population gains during recent periods.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022. For areas not covered and post-2032 estimations, AreaSearch utilises growth rates by age cohort provided by the ABS in its Greater Capital Region projections released in 2023 based on 2022 data. Looking ahead, regional areas are projected to have above median population growth, with Collie expected to expand by 1,368 persons to 2041, reflecting a total increase of 13.8% over the 17 years.

Residential development activity is slightly higher than average within Collie when compared nationally

Collie has recorded approximately 28 residential properties granted approval annually. Over the past five financial years, from FY-21 to FY-25, around 140 homes were approved, and an additional 20 have been approved so far in FY-26. On average, about 3.4 people moved to the area each year for every dwelling built during these five years.

This high demand has outpaced supply, putting upward pressure on prices and increasing competition among buyers. The average expected construction cost value of new homes being built is around $277,000. In terms of commercial investment activity, Collie has registered approximately $16.9 million in approvals this financial year. Compared to the rest of WA, Collie records roughly half the building activity per person.

Nationally, it places among the 49th percentile of areas assessed, indicating relatively constrained buyer choice and supporting interest in existing dwellings. The new building activity shows a traditional low density character with around 82.0% detached houses and 18.0% medium and high-density housing. This focus on family homes appeals to those seeking space. With approximately 331 people per dwelling approval, Collie indicates a developing market. Looking ahead, the latest AreaSearch quarterly estimate projects that Collie is expected to grow by 1,311 residents through to 2041. At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.
