Serpentine (WA)

Serpentine lies within the top quartile of areas nationally for population growth performance according to AreaSearch analysis of recent, and medium to long-term trends

Based on analysis of ABS population updates for the broader area, as of November 2025, the Serpentine (WA) statistical area (Lv2)'s estimated population is around 3,324. This reflects an increase of 461 people since the 2021 Census, which reported a population of 2,863. The change was inferred from AreaSearch's resident population estimate of 3,185 following examination of the latest ERP data release by the ABS in June 2024 and an additional 53 validated new addresses since the Census date. This level of population equates to a density ratio of 31 persons per square kilometer. The Serpentine (WA) (SA2)'s growth rate of 16.1% since the 2021 census exceeded both national average (9.7%) and state averages, marking it as a growth leader in the region. Population growth was primarily driven by interstate migration contributing approximately 48.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022, and utilising growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections released in 2023 based on 2022 data for areas not covered. Considering projected demographic shifts, a population increase just below the median is expected for the Serpentine (WA) statistical area (Lv2), with an expected growth of 317 persons to reach approximately 3,641 by 2041, reflecting a gain of 4.8% in total over the 17 years.

Recent residential development output has been above average within Serpentine when compared nationally

Serpentine has received around 22 dwelling approvals annually over the past five financial years, totalling an estimated 116 homes from FY-21 to FY-25. As of FY-26, 16 approvals have been recorded. On average, 2.7 people per year moved to Serpentine with each new home constructed during this period, indicating strong demand that supports property values. The average construction cost value for new homes was $382,000, higher than regional norms due to quality-focused development.

This financial year, $3.8 million in commercial approvals have been registered, reflecting Serpentine's primarily residential nature. Compared to Greater Perth, Serpentine has approximately half the rate of new dwelling approvals per person and ranks among the 66th percentile nationally when assessed areas are considered. All new construction in Serpentine has consisted of standalone homes, maintaining its traditional low-density character and appealing to those seeking space with family homes.

With around 215 people per dwelling approval, Serpentine exhibits a developing market. According to AreaSearch's latest quarterly estimate, Serpentine is projected to add 158 residents by 2041. Given current development patterns, new housing supply should meet demand, providing favourable conditions for buyers and potentially facilitating population growth beyond current projections.
