This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Population
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, the population of St Peters's suburb is estimated at around 3,317 as of May 2026. This reflects an increase of 86 people (2.7%) since the 2021 Census, which reported a population of 3,231 people. The change is inferred from the resident population of 3,315 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2025 and an additional four validated new addresses since the Census date. This level of population equates to a density ratio of 2,211 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Population growth for the suburb was primarily driven by overseas migration that contributed approximately 92.0% of overall population gains during recent periods.
AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with a base year of 2022. For any SA2 areas not covered by this data and years post-2032, the SA State Government's Regional/LGA projections by age category are adopted, released in 2023 and based on 2021 data, with adjustments made using 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 for the suburb of St Peters (SA), with an expected expansion by 320 persons to reach 2041 based on aggregated SA2-level projections. This reflects an anticipated gain of 9.6% in total over the 16 years.

Development
AreaSearch assessment of residential development drivers sees a low level of activity in St Peters, placing the area among the bottom 25% of areas assessed nationally
St Peters has seen approximately 9 new homes approved annually based on AreaSearch analysis of ABS building approval numbers. Around 49 homes were approved in the past 5 financial years, from FY-21 to FY-25, with an additional 9 approved so far in FY-26. On average, about 1.3 new residents arrived per year for each new home over these five years. However, this figure has recently accelerated to 6.4 people per dwelling over the past two financial years, suggesting increasing demand and tightening supply.
New properties are constructed at an average value of $836,000, indicating a focus on the premium segment with upmarket properties. This year alone, there have been $11.8 million in commercial approvals, reflecting steady commercial investment activity. Comparatively, St Peters has significantly less development activity than Greater Adelaide, with 55.0% below the regional average per person. This scarcity of new dwellings typically strengthens demand and prices for existing properties. Nationally, this level is also below average, possibly due to the area's maturity or planning constraints.
New development in St Peters consists of 60.0% standalone homes and 40.0% attached dwellings, offering choices across price ranges from spacious family homes to more compact options. With around 396 people per dwelling approval, St Peters shows a developed market. According to the latest AreaSearch quarterly estimate, the population is forecasted to gain 318 residents by 2041. Development appears to be keeping pace with projected growth, though increasing competition among buyers may arise as the population expands.

New Women's and Children's Hospital
A $3.2 billion state-of-the-art facility being developed as Australia's first all-electric public hospital. As of April 2026, the 1,300-space multi-storey car park is nearing completion, and main hospital construction has commenced with inground and structural works. The project features 414 overnight beds, a larger emergency department with 43 treatment spaces, a dedicated helipad, and co-location of all critical care services on a single floor. Early enabling works by SA Water for utility upgrades are currently underway through Bonython Park and Park 25, with utility installations expected to continue until late March 2027.
SA Water Capital Work Delivery Contracts 2024-28

The program targets water main replacements, sewerage network upgrades, dam upgrades, water tank refurbishments, and treatment process upgrades across metropolitan and regional areas. A central $1.5 billion component supports the South Australian Premier's Housing Roadmap, expanding network capacity to unlock up to 40,000 new allotments, with major focus on Adelaide's northern growth corridors including Angle Vale, Riverlea, and Roseworthy. Six major framework partners (Fulton Hogan Utilities, John Holland and Guidera O'Connor JV, McConnell Dowell and Diona JV, BMD, Diona, and Leed Engineering and Construction) are delivering works across approximately 120 projects.

Tarrkarri - Centre for First Nations Cultures
A planned First Nations cultural centre at Lot Fourteen on the former Royal Adelaide Hospital site, designed by Diller Scofidio + Renfro with Woods Bagot. The 11,500 square metre, three-level facility would feature 7,000 square metres of exhibition space, performance venues, outdoor amphitheatre, and immersive storytelling technology celebrating over 60,000 years of Aboriginal and Torres Strait Islander culture. Originally costed at $200 million under the Adelaide City Deal (Australian Government $85m, SA Government $115m), construction was halted in October 2022 after cost estimates blew out to between $400 million and $600 million. As of late 2025, the site remains vacant while the SA Government seeks major philanthropic co-funding. No timeline for resumption has been confirmed.
274-275 North Terrace Development Site
A landmark 2,800 square metre triple-street frontage development site at the corner of North Terrace and Frome Road, directly opposite Lot Fourteen Innovation Precinct and Adelaide University. Renewal SA acquired both sites and completed demolition of the former SA Health building at 275 North Terrace in mid-2025. An Expression of Interest process closed in early 2025 via JLL Australia, attracting strong developer interest. Negotiations with a preferred development partner were underway as of June 2025, with an announcement anticipated shortly after. The site offers potential for one or more high-rise towers incorporating market apartments, build-to-rent, hotel, purpose-built student accommodation, affordable housing, and ground floor retail and hospitality uses. The project could generate more than $250 million in construction activity and up to $450 million in market value.

During the year to December 2025, employment levels increased by 4.3%, and labour force grew by 4.2%, reducing the unemployment rate by 0.1 percentage points. Greater Adelaide recorded employment growth of 4.2% with unemployment falling 0.3 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 project national employment expansion by 6.6% over five years and 15.3% over ten years. Applying these projections to St Peters' employment mix suggests local employment should increase by 7.5% over five years and 15.3% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not consider localised population projections.
