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

As of Feb 2026, the estimated population of the suburb of Mardi is around 3,648, reflecting an increase of 50 people since the 2021 Census. This increase corresponds to a growth rate of 1.4%. The resident population estimate of 3,640 by AreaSearch, based on the latest ERP data release by the ABS in June 2024 and two validated new addresses since the Census date, indicates this growth. This results in a density ratio of 384 persons per square kilometer. Mardi's population growth rate of 1.4% since the census is within 2.3 percentage points of the SA4 region's rate of 3.7%, indicating competitive growth fundamentals. Overseas migration contributed approximately 63.0% of overall population gains during recent periods, driving primary growth in the area.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. By 2041, the suburb of Mardi is expected to increase its population by 261 persons based on aggregated SA2-level projections, reflecting a total increase of 7.0% over the 17-year period. This growth projection places the area just below the median for Australian statistical areas.

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 shows virtually no dwelling approvals in Mardi recently. Between FY21 and FY25, an estimated 4 homes were approved, with 0 so far in FY26.
