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.

Sales Detail
Mardi has an estimated 3,680 residents, up from 3,598 at the 2021 Census — a change of 82 people, or 2.3%. That puts 387 residents on each square kilometre. Population is estimated from ABS Estimated Resident Population releases and GNAF address data, re-based from the 2021 Census and updated annually.
Detail
According to AreaSearch evaluations combining ABS demographic revisions across the broader region with 2 validated new addresses recorded following the Census date, the suburb of Mardi has an Estimated Resident Population (ERP) of approximately 3,680 as of Aug 2026. This marks an expansion of 82 people (2.3%) from the 3,598 people enumerated in the 2021 Census, a projection established by reviewing the ABS release from June 2025. With a population density calculated at 387 persons per square kilometer, the locality offers generous space per resident along with capacity for additional development.
The suburb of Mardi achieved a 2.3% post-census growth rate that sits within 1.1 percentage points of the wider SA4 region (3.4%), underscoring steady expansion drivers. Most of this recent population expansion stemmed from overseas migration, which represented approximately 63.0% of total demographic gains. Projections for each SA2 territory incorporate ABS/Geoscience Australia modeling published in 2024 (using 2022 as baseline), supplemented where necessary by NSW State Government SA2 forecasts released in 2022 (anchored to 2021). Age-specific expansion patterns from these datasets have been projected forward for all districts covering the 2032 to 2041 timeframe. Anticipated structural demographic adjustments indicate that the suburb of Mardi will experience population expansion slightly beneath the median across Australian statistical areas. SA2-level aggregate figures project an increase of 258 persons by 2041, representing an overall expansion of 7.0% across the 16 years.
Frequently Asked Questions - Population
Detail
Only 1 residential development approval has been registered within the locality throughout the prior five years. This near-total lack of fresh building activity points to a mature neighborhood with scarce opportunities for new construction. Such conditions tend to underpin prevailing residential valuations, although prospective purchasers should anticipate a steady market characterized by lower turnover. Relative to Greater Sydney, the volume of building approvals in the local area is considerably lower. While construction activity has exhibited minor recent gains, the overall constraint on new housing supply consistently reinforces buyer demand and pricing for existing stock.
Local construction levels remain below the nationwide norm as well, reflecting the established setting of the suburb and pointing to possible planning constraints.

1,990 residents of Mardi are employed, from a labour force of 2,049. Unemployment sits at 2.9%, with participation at 69.8%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.5% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 4,533, about 123% of the resident population, so the area draws in more workers than it sends out. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.
Detail
Mardi boasts a highly skilled labor pool, with key service industries well represented, an unemployment rate of just 2.9%, and an estimated employment growth of 2.5% over the past year, according to AreaSearch aggregation of statistical area data. As of March 2026, 1,990 residents are in work while the unemployment rate is 1.2% below Greater Sydney's rate of 4.1%, and workforce participation is broadly similar to Greater Sydney's 68.9%. Based on Census responses, a high 28.5% of residents were found to work from home, though Covid-19 lockdown impacts should be considered.
The primary employment fields for the resident workforce consist of health care & social assistance, retail trade, and construction. By comparison, professional & technical roles account for only 6.6% of jobs held by residents, underperforming Greater Sydney's 11.5%. Recording 1.0 workers for every resident at the Census, the locality operates as an employment center that sustains more positions than local residents and draws workers from adjoining districts. AreaSearch assessment of ABS and SALM figures aggregated across wider statistical divisions indicates that over the 12-month period, local employment expanded by 2.5% while the total workforce grew by 3.3%, yielding an 0.8 percentage points increase in the jobless rate. Concurrently, Greater Sydney saw both employment and workforce numbers rise by 1.9%, accompanied by a minor decrease in unemployment. Forward-looking employment estimates published by Jobs and Skills Australia in Mar-26 provide additional context regarding future hiring across the district over five and ten-year horizons. Across the country, total employment is anticipated to climb by 6.6% over five years and 13.7% over ten years, with marked divergence across sectors. Aligning these industry trajectories with the local sector distribution suggests local employment growth of 6.5% over five years and 13.5% over ten years (note that this weighting model serves an illustrative purpose and excludes localized demographic forecasts).

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 — 2 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (3,598 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.
