St Peters (SA)

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

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch, St Peters (SA) statistical area (Lv2)'s population is estimated at around 3,486 as of Nov 2025. This reflects an increase of 255 people (7.9%) since the 2021 Census, which reported a population of 3,231 people. The change is inferred from the resident population of 3,381, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024, and an additional 3 validated new addresses since the Census date. This level of population equates to a density ratio of 2,324 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. St Peters' (SA) 7.9% growth since census positions it within 0.8 percentage points of the state's 8.7%, demonstrating competitive growth fundamentals. Population growth for the area was primarily driven by overseas migration, contributing approximately 92.0% of overall population gains during recent periods.

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 for years post-2032, the SA State Government's Regional/LGA projections by age category, released in 2023 and based on 2021 data, are adopted with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Moving forward with demographic trends, a population increase just below the median of national areas is expected, with the area expected to expand by 361 persons to reach 3,847 by 2041 based on aggregated SA2-level projections, reflecting a gain of 7.7% in total over the 17 years.

Residential development activity is lower than average in St Peters according to AreaSearch's national comparison of local real estate markets

AreaSearch analysis of ABS building approval numbers shows St Peters had around 10 new homes approved annually. Between FY-21 and FY-25, approximately 50 homes were approved, with another 8 so far in FY-26. Over the past five financial years, an average of 2.4 people moved to the area per new home constructed.

This suggests solid demand supporting property values, with new homes being built at an average expected construction cost value of $836,000, indicating a focus on the premium segment. In FY-26, there have been $11.8 million in commercial approvals, showing steady commercial investment activity. Compared to Greater Adelaide, St Peters has 55.0% less development activity per person. This scarcity typically strengthens demand and prices for existing properties, reflecting the area's maturity and possible planning constraints. New development consists of 60.0% standalone homes and 40.0% attached dwellings, offering choices across price ranges.

With around 396 people per dwelling approval, St Peters shows a developed market. Population forecasts indicate St Peters will gain 267 residents by 2041, with current development well-matched to future needs, supporting steady market conditions without extreme price pressure.

Jobs and Skills Australia's national employment forecasts from May-25 suggest that national employment should expand by 6.6% over five years and 13.7% over ten years.
