This analysis uses ABS Statistical Areas Level 2 (SA2) boundaries, which can materially differ from Suburbs and Localities (SAL) even when sharing similar names.
SA2 boundaries are defined by the Australian Bureau of Statistics and are designed to represent communities for statistical reporting (e.g., census and ERP).
Suburbs and Localities (SAL) represent commonly-used suburb/locality names (postal-style areas) and may use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Detail
According to the analysis by AreaSearch, the population of Quorn - Lake Gilles is approximately 2,170 as of May 2026. This represents an expansion of 28 people (1.3%) from the 2,142 individuals recorded during the 2021 Census. This population shift is deduced using the ABS estimated resident population of 2,170 from June 2025 alongside 36 validated new addresses registered since the Census. With this population level, the density ratio stands at 0.10 persons per square kilometer, indicating a setting with substantial personal space. Over the last decade, Quorn - Lake Gilles has shown stable development trends with a -0.3% compound annual growth rate, which is ahead of the SA3 area.
The population increase in this locality was mostly fueled by overseas migration, which accounted for roughly 73.7% of the total population gains in recent times. AreaSearch utilizes ABS/Geoscience Australia projections for individual SA2 sectors, which were published in 2024 using 2022 as the baseline year. For any SA2 sectors excluded from this dataset, as well as for the period following 2032, the SA State Government's Regional/LGA age group projections released in 2023 and based on 2021 data are utilized, with modifications applied through a weighted aggregation of population changes from the LGA level to the SA2 level. Projecting future population movements under this approach, a contraction in the overall population is indicated, with the region expected to decrease by 12 persons by 2041. On the other hand, expansion is expected within particular age cohorts, led by the group aged 85 and over, which is projected to expand by 125 people. Refer to the age section for further details.
Frequently Asked Questions - Population
40 new dwellings have been approved in Quorn - Lake Gilles over the past five years, an average of 8 a year. That is 3.7 approvals per 1,000 residents. Few approvals have been recorded in the most recent months, well below the longer-run average; the latest ABS periods are still being reported.

Detail
Quorn - Lake Gilles has seen approximately 8 dwellings approved for development each year, amounting to 40 homes over the last 5 financial years. Thus far in FY-26, 0 approvals have been documented. Since the region has experienced a decline in population, the incoming supply has likely matched local demand, providing suitable options for purchasers, while new dwellings are being constructed at an average cost of $221,000, aligning with broader regional patterns. Furthermore, $1.2 million in commercial approvals have been registered during this financial year, pointing to a majorly residential emphasis.
In comparison to the Rest of SA, Quorn - Lake Gilles exhibits 163.0% more construction activity (per person), which ought to give purchasers plenty of options, even though building activity has slowed down lately. Recent construction statistics show 50.0% detached houses and 50.0% medium and high-density housing. Emphasizing higher-density accommodation provides more economical entry points and accommodates downsizers, investors, and first-time home buyers. This represents a clear shift from the current housing stock (which stands at 94.0% houses), indicating a decline in the availability of developable land and reflecting changing lifestyle choices and housing affordability demands. The ratio of 400 people in the area per dwelling approval highlights a quiet, low-scale development sector. Given that the population is projected to remain steady or contract, Quorn - Lake Gilles is likely to experience less pressure on its housing market, which could present favorable options for buyers.

1,022 residents of Quorn - Lake Gilles are employed, from a labour force of 1,084. Unemployment sits at 5.7%, with participation at 57.5%. Weighted for its industry mix, the area's sectors are forecast to grow about 5.5% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.
Detail
Quorn - Lake Gilles features a proportionate workforce distributed across white and blue collar jobs, with diverse representation across various industries, and an unemployment rate of 5.7%. As of March 2026, 1,022 local citizens are employed, which is an unemployment rate 0.3% higher than the Regional SA average of 5.5%, while workforce participation closely matches the Regional SA average of 58.4%. According to the Census, a modest 12.1% of residents performed their jobs from home, though the influence of Covid-19 lockdowns should be kept in mind. The primary sectors of employment for local residents consist of agriculture, forestry & fishing, health care & social assistance, and accommodation & food.
The region shows a specific concentration of jobs in mining, with a workforce share that is 2.6 times the regional rate. By contrast, manufacturing is less represented at 1.8% compared to the regional average of 9.3%. Though local jobs are available in the district, the comparison of the Census working population against the local population suggests that many residents travel outside the area for work. An analysis of SALM and ABS statistics by AreaSearch shows that over the 12-month span, the labor force shrank by 1.7% and total employment dropped by 4.6%, leading to a rise in unemployment of 2.8 percentage points. This differs from Regional SA, where employment expanded by 1.2%, the labor force increased by 2.6%, and unemployment rose by 1.4 percentage points. National employment forecasts from Jobs and Skills Australia dated May-25 can provide additional perspective on prospective demand in Quorn - Lake Gilles. These forecasts, which span five and ten-year horizons, have been aligned with the local employment distribution to estimate growth trends. Although national employment is projected to grow by 6.6% over five years and 13.7% over ten years, the rate of growth varies considerably by industry sector. Applying these sector-specific forecasts to the employment structure of Quorn - Lake Gilles suggests that local jobs should rise by 5.5% over five years and 12.0% over ten years (note that this is a basic weighted extrapolation for demonstration purposes and does not account for localized population changes).

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 — 36 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (2,142 at the 2021 Census → 2,170 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 May 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.
Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (406021140). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.
