Mardi

Mardi 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 since the Census, Mardi's estimated population is around 3,646 as of Nov 2025. This reflects an increase of 48 people (1.3%) since the 2021 Census, which reported a population of 3,598 people. The change was inferred from the resident population of 3,640 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional two validated new addresses since the Census date. This level of population equates to a density ratio of 383 persons per square kilometer. Mardi's 1.3% growth since census positions it within 2.4 percentage points of the SA4 region (3.7%), demonstrating competitive growth fundamentals. Population growth for the area was primarily driven by overseas migration, contributing approximately 63.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, AreaSearch is utilising the NSW State Government's SA2 level projections, as released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are also applied to all areas for years 2032 to 2041. Looking at population projections moving forward, a population increase just below the median of Australian statistical areas is expected, with the Mardi SA2 expected to increase by 249 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 6.6% in total over the 17 years.

The level of residential development activity in Mardi is very low in comparison to the average area assessed nationally by AreaSearch

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, shows Mardi has had virtually no dwelling approvals in recent years. Specifically, an estimated 4 homes were approved between financial year 2021 and 2025, with 0 so far in the current financial year 2026. Despite a falling population during this period, housing supply has remained adequate relative to demand, resulting in a well-balanced market with good buyer choice.

New properties are constructed at an average expected construction cost value of $383,000. Additionally, $40,000 in commercial development approvals have been recorded this financial year 2026, indicating the area's residential nature. Compared to Greater Sydney, Mardi shows substantially reduced construction activity. This limited new supply generally supports stronger demand and values for established homes, although building activity has accelerated in recent years. Nationally, this is below average, reflecting the area's maturity and possible planning constraints. Recent development has been entirely comprised of detached dwellings, maintaining the area's traditional low density character with a focus on family homes appealing to those seeking space. This favours detached housing more than current patterns suggest (78.0% at Census), demonstrating ongoing robust demand for family homes despite increasing density pressures. The estimated count of 1818 people in the area per dwelling approval reflects its quiet, low activity development environment.

As of 25-November, NSW employment has contracted by 0.03% (losing 2,260 jobs), with the state's unemployment rate at 3.9%. This compares favourably to the national unemployment rate of 4.3%. Jobs and Skills Australia's national employment forecasts from May-25 suggest that national employment should expand by 6.6% over five years and 13.7% over ten years, with significant variations in growth rates between industry sectors. Applying these projections to Mardi's employment mix indicates that local employment is expected to increase by 6.5% over five years and 13.5% over ten years.
