AreaSearch uses ABS/Geoscience Australia projections for each SA2 area released in 2024, based on data from 2022. For areas not covered by this data and years post-2032, Queensland State Government's SA2 area projections from 2023 are adopted. These state projections do not provide age category splits; thus, AreaSearch applies proportional growth weightings in line with ABS Greater Capital Region projections released in 2023, based on 2022 data for each age cohort. Future population trends indicate an above median growth for the area analysed by AreaSearch. Based on the latest annual ERP population numbers, Alderley is projected to grow by 1,425 persons to 2041, reflecting a total gain of 19.6% over the 16-year period.

AreaSearch assessment of residential development activity positions Alderley among the top 25% of areas assessed nationwide

Alderley has seen approximately 65 dwellings approved annually. Over the past five financial years, from FY21 to FY25, around 327 homes were approved, with an additional 22 approved in FY26 so far. On average, each new home attracts about two new residents per year over these five years, indicating a balanced supply and demand scenario, which supports stable market conditions.

The average construction cost value of new dwellings is $432,000, reflecting developers' focus on the premium segment with upmarket properties. In FY26, there have been commercial approvals totalling $768,000, suggesting a predominantly residential development focus compared to Greater Brisbane, where Alderley shows moderately higher development activity, being 35.0% above the regional average per person over the five-year period. The new building activity in Alderley is predominantly attached dwellings at 82.0%, with detached dwellings making up 18.0%. This shift towards higher-density living creates more affordable entry points and caters to downsizers, investors, and first-home buyers, representing a notable change from the area's existing housing composition of 58.0% houses. With around 267 people per dwelling approval, Alderley is showing signs of a developing market.

According to the latest AreaSearch quarterly estimate, Alderley is forecasted to gain approximately 1,425 residents by 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting population growth beyond current projections.
