Sales Detail
Mardi has an estimated 3,682 residents, up from 3,598 at the 2021 Census — a change of 84 people, or 2.3%. That puts 388 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
In the suburb of Mardi, the resident population is projected to be approximately 3,682 in May 2026, an evaluation derived from ABS population updates for the wider region and new home locations verified by AreaSearch since the Census. This indicates an expansion of 84 individuals (2.3%) from the 2021 Census, which recorded 3,598 residents. This shift is calculated from a resident base of 3,681, projected by AreaSearch using the ABS June 2025 ERP release alongside 2 validated new addresses registered after the Census date. Such a population size results in 387 persons per square kilometer, which indicates substantial space per individual and capacity for future housing additions.
The 2.3% post-census growth rate for the suburb of Mardi is within 1.1 percentage points of the broader SA4 region (3.4%), showing healthy growth dynamics. The expansion was largely propelled by arrivals from overseas, who made up roughly 63.0% of the overall population increases in recent times. AreaSearch implements projections from the ABS and Geoscience Australia for individual SA2 zones, published in 2024 using 2022 as the baseline. For SA2 territories lacking this dataset, NSW State Government projections from 2022 with a 2021 baseline are substituted. The age-bracket growth trends from these sources are extended to cover all localities for the period spanning 2032 to 2041. Future expectations for the suburb of Mardi point to a population gain slightly under the median for Australian statistical zones, with a projected rise of 254 residents by 2041 based on compiled SA2 figures, representing a 6.9% total expansion over the 16 years.
Frequently Asked Questions - Population
Detail
Property developers have completed very little work here, with only 1 approval granted over a five-year timeframe. This low level of activity points to a fully developed residential environment where new construction projects are uncommon. While this restricted building volume can support established home values by limiting available stock, it also points to a quiet, settled housing market with minimal sales transaction volumes. Relative to Greater Sydney, building activity in this locality is significantly lower. While this constrained volume of new additions typically helps bolster demand and support values for existing homes, local building projects have recently become more active.
The rate of building is also below the national benchmark, highlighting the established nature of the locality and hinting at potential regulatory or planning boundaries.

1,997 residents of Mardi are employed, from a labour force of 2,055. Unemployment sits at 2.8%, with participation at 70.0%. 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
A highly capable workforce resides here, showing strong representation in crucial service industries, a jobless rate of only 2.8%, and a 2.5% increase in local jobs over the prior year, according to compiled regional data from AreaSearch. In March 2026, working residents numbered 1,997, with the unemployment rate sitting 1.3% below the 4.1% recorded for Greater Sydney, while workforce participation aligned closely with the metropolitan rate of 69.1%. Census records indicate that 28.5% of working locals did their jobs from home, although this figure was likely influenced by pandemic-related movement restrictions.
Local workers are highly concentrated in retail trade, health care & social assistance, and construction. Conversely, professional & technical roles are underrepresented, accounting for 6.6% of employment compared to 11.5% across the broader region. Recording 1.0 employed individuals for every local resident at the Census, the locality operates as a employment destination, providing a higher number of positions than resident workers and drawing commuters from neighboring suburbs. Based on AreaSearch processing of SALM and ABS statistics for the wider statistical territory, the twelve months leading to March 2026 saw employment expand by 2.5% and the overall labor force grow by 3.4%, which pushed the unemployment rate up by 0.8 percentage points. In comparison, Greater Sydney saw employment rise by 1.9% and its labor force grow by 1.9%, alongside a slight reduction in jobless numbers. Workforce projections released by Jobs and Skills Australia in May-25 offer additional perspective on prospective hiring trends. These forecasts, spanning five and ten-year horizons, have been aligned with the local industry breakdown to project growth. While national jobs are expected to rise by 6.6% over five years and 13.7% over ten years, the rates of change vary widely by sector. Projecting these industry trends onto the local workforce profile suggests employment will rise by 6.5% over five years and 13.5% over ten years, representing a basic weighted projection for visualization purposes that 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 — 2 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (3,598 at the 2021 Census → 3,682 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.
