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.

Detail
According to AreaSearch's evaluation of broader ABS population metrics alongside post-Census address validations, the suburb of Lewiston holds an estimated population of approximately 3,680 as of Aug 2026. This represents a rise of 405 people (12.4%) relative to the 3,275 people tallied in the 2021 Census. Such growth builds upon an estimated resident total of 3,568 identified in the June 2025 ABS ERP release, supplemented by 121 validated new addresses confirmed following the Census. Overall density stands at 89 persons per square kilometer, ensuring considerable open space alongside opportunities for future expansion.
The local expansion rate of 12.4% since the 2021 census outpaced both South Australia (7.7%) and Greater Adelaide, establishing the suburb of Lewiston as an area of notable regional momentum. Interstate arrivals served as the principal catalyst, accounting for roughly 79.0% of recent population additions, though natural increase and overseas arrivals also registered positive contributions. Projections utilize 2024 ABS/Geoscience Australia models starting from a 2022 baseline for local SA2 regions. In locations lacking direct coverage or extending beyond 2032, models integrate 2023 SA State Government LGA age-cohort projections grounded in 2021 figures, adapted via weighted aggregation methods. Looking forward, the suburb of Lewiston is positioned within the top quartile of regions evaluated by AreaSearch, with aggregated SA2 figures pointing to an expansion of 1,300 persons by 2041, representing an overall rise of 32.3% across the 16-year timeframe.
Frequently Asked Questions - Population
247 new dwellings have been approved in Lewiston over the past five years, an average of 49 a year. That places the area in the 72nd percentile for residential development activity nationally, about 13 approvals per 1,000 residents a year. Of the 40 dwellings approved in the latest reporting year, 100% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 23, well below that longer-run average. Figures come from ABS building approvals aggregated to this Suburb (SAL) boundary and are updated monthly as the ABS releases them.
Detail
Statistical evaluations of ABS building figures by AreaSearch show that Lewiston averages roughly 49 residential approvals annually, totaling approximately 247 homes over the last 5 financial years (between FY-21 and FY-25), with 23 recorded to date in FY-25. Construction of new dwellings has coincided with an average intake of 2 new residents per year per dwelling between FY-21 and FY-25, highlighting a balanced residential market with stable conditions. Building activity emphasizes premium construction, with average anticipated building costs reaching $454,000 to exceed regional benchmarks. Meanwhile, commercial approvals reached $3.3 million this financial year, underscoring the predominantly residential focus of local building activity.
On a per-capita basis, building approvals in Lewiston track 12.0% below Greater Adelaide levels, yet the locality places in the 84th percentile nationwide. This elevated national standing underscores substantial builder and developer interest. All recent residential approvals have consisted exclusively of separate houses, maintaining the neighborhood's low-density environment and catering to households desiring larger allotments. Featuring approximately 102 people per dwelling approval, the locality continues to exhibit key indicators of steady residential development. Long-term demographic forecasts anticipate Lewiston expanding by 1,188 residents by 2041 compared to the most recent quarterly estimate from AreaSearch. Current residential pipeline volumes appear well-positioned to satisfy incoming demand, fostering favorable buyer conditions while accommodating population growth beyond current projections.

Two Wells Main Street Masterplan
A project to revitalise the main street of Two Wells through urban design projects, including renewing the public realm, improving accessibility, and undergrounding powerlines.
1,727 residents of Lewiston are employed, from a labour force of 1,792. Unemployment sits at 3.6%, with participation at 60.5%. Weighted for its industry mix, the area's sectors are forecast to grow about 5.8% nationally over five years. That reflects industry composition only and makes no allowance for local population growth, so in an area growing as fast as this one it understates the likely rise in local jobs. The working-day population is estimated at 3,183, about 86% of the resident population, so more people leave the area for work than travel in. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.
Detail
Lewiston features a balanced employment base encompassing both professional and manual vocations, highlighted by a notable concentration in building and construction trades and a modest jobless rate of 3.6%, according to AreaSearch statistical area compilations. In March 2026, employed residents numbered 1,727, while the local unemployment rate sat 0.2% lower than the 3.8% recorded across Greater Adelaide. By contrast, local workforce participation of 60.5% trails the Greater Adelaide benchmark of 66.4%. Census records also showed that only 9.1% of workers operated from home, though broader pandemic context during Covid-19 should be noted.
Resident employment centers primarily around construction, health care & social assistance, alongside retail trade. Building trades demonstrate heavy local specialization, recording an employment concentration 1.7 times the regional norm. Conversely, health care & social assistance engages 12.7% of working residents, falling short of the 17.7% regional baseline. Comparing the local resident workforce against the number of jobs physically located within the area indicates that internal employment opportunities remain relatively constrained. Examining SALM and ABS statistical data over the preceding 12-month period reveals a 4.1% reduction in the local labor force alongside a 4.6% drop in overall employment, leading to a 0.5 percentage points uptick in the jobless rate. This diverged from Greater Adelaide, where job numbers expanded by 4.2%, the labor pool grew by 4.0%, and joblessness declined by 0.2 percentage points. Future labor requirements can be gauged through Jobs and Skills Australia projections released in Mar-26. Nationally, total employment is anticipated to climb 6.6% across five years and 13.7% across ten years, though industry trajectories vary widely. When applied directly to Lewiston's unique industry composition, projected local workforce growth equates to 5.8% over five years and 12.3% over ten years (representing a baseline illustrative weighting that excludes localized population adjustments).

How the numbers are built
Population
The Census provides the small-area baseline, aggregated from mesh blocks to this boundary. It is then re-based to the ABS Estimated Resident Population (June 2025 release), and new dwellings built since Census night are counted from address data — 121 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (3,275 at the 2021 Census → 3,680 now). Annual growth rates are compound (CAGR), not simple averages.
Age profile
Cohort shares are not raw Census counts. Every cohort is held as a pair — the Census baseline and a current estimate — and the split is re-based using ERP and state population projections, current to Aug 2026. Median age is the Census median plus modelled change since. Charts that show both are labelled "2021 Census vs Current Estimate".
Property sales
Sourced from the state valuation authority's sales register — current, not Census, and refreshed weekly. Medians are calculated from settled transactions in the period shown; periods with very low transaction counts are flagged or suppressed, because a handful of sales can move a median substantially.
Rents
Derived from state rental bond lodgement data, by dwelling type and bedroom count. Bonds are lodged at the start of a new tenancy, so this reflects new lettings, not the whole rented stock.
Development & infrastructure
Building approvals come from current ABS releases; development applications are collected from council and state planning portals; the infrastructure pipeline is compiled from Infrastructure Australia and local government sources. Applications are matched to this boundary by address or coordinates, so very recent lodgements may not yet appear.
Employment & income
Industry and occupation structure comes from the Census, but the headline labour-market indicators do not. Unemployment and labour force are derived from ABS Small Area Labour Markets (quarterly). The employment outlook applies Department of Employment forecasts for all 19 industry divisions to this area's own industry mix (the agency is now Jobs and Skills Australia), as does the Internet Vacancy Index used for job demand. Because it is weighted on industry composition alone, that outlook carries no allowance for local population growth — in fast-growing areas the real rise in local jobs will typically be higher. Income combines Census household income with ATO taxable-income statistics for FY 2023, indexed forward using the Wage Price Index.
Education, transport & amenities
School enrolments, ICSEA and performance come from ACARA's current release, not the Census. Public transport stops and service frequency are derived from GTFS timetable feeds published by state transport departments. Services and amenities are proximity and count scores built from provider directories, refreshed on their own cycle. The Census contributes only the travel-to-work and qualification measures.
Rankings and benchmarks. Where we rank this area, the comparison set is every area of the same boundary type — suburbs against suburbs, SA2s against SA2s. Benchmarks compare this area against its greater capital city region and the national figure for the same measure and period.
Limits worth knowing. Small areas carry larger error margins, and the ABS introduces small random adjustments to Census counts to protect confidentiality — so totals may not sum exactly. Estimates re-based from regional data describe the area's expected trajectory, not a direct count of it. Figures are indicative for research and are not financial, planning or valuation advice.
