AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, and to estimate growth across all areas in the years post-2032, AreaSearch is utilising the growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections (released in 2023, based on 2022 data). As we examine future population trends, a population increase just below the median of national areas is expected, with the area expected to expand by 510 persons to 2041 based on the latest annual ERP population numbers, recording a gain of 5.7% in total over the 17 years.

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

Serpentine - Jarrahdale has averaged around 27 new dwelling approvals per year, with 135 homes approved over the past 5 financial years (between FY-21 and FY-25) and 25 so far in FY-26. Given an average of 3.5 new residents per year arriving per dwelling constructed over the past 5 financial years (between FY-21 and FY-25), demand significantly exceeds new supply, which usually results in price growth and increased buyer competition, while new properties are constructed at an average value of $283,000. Additionally, $4.1 million in commercial approvals have been registered this financial year, demonstrating the area's primarily residential nature.

When measured against Greater Perth, Serpentine - Jarrahdale has significantly less development activity (59.0% below regional average per person). This scarcity of new homes typically strengthens demand and prices for existing properties. Meanwhile, recent building activity consists entirely of standalone homes, maintaining the area's traditional low density character with a focus on family homes appealing to those seeking space. At around 302 people per approval, Serpentine - Jarrahdale reflects a transitioning market.

Population forecasts indicate Serpentine - Jarrahdale will gain 300 residents through to 2041 (from the latest AreaSearch quarterly estimate). Based on current development patterns, new housing supply should readily meet demand, offering good conditions for buyers and potentially facilitating population growth beyond current projections.
