Marayong

An assessment of population growth drivers in Marayong reveals an overall ranking slightly below national averages considering recent, and medium term trends

As of 1 November 2025, the estimated population of Marayong is around 7,866. This figure represents an increase of 32 people since the 2021 Census, which recorded a population of 7,834. The change is inferred from AreaSearch's estimate of 7,846 residents following examination of the latest ERP data release by the ABS in June 2024, along with an additional 41 validated new addresses since the Census date. This results in a density ratio of approximately 2,902 persons per square kilometer, placing Marayong in the upper quartile relative to national locations assessed by AreaSearch. Over the past decade, Marayong has exhibited resilient growth patterns, with a compound annual growth rate of 1.6%, surpassing that of its SA3 area. Overseas migration contributed approximately 68.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year, and NSW State Government's SA2 level projections for areas not covered by this data, released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Based on aggregated SA2-level projections, Marayong is expected to grow by 878 persons to 2041, reflecting a gain of approximately 14.3% in total over the 17-year period.

AreaSearch analysis of residential development drivers sees Marayong recording a relatively average level of approval activity when compared to local markets analysed countrywide

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, indicates Marayong has experienced around 26 dwellings receiving development approval per year over the past five financial years. This totals an estimated 130 homes. So far in FY-26, nine approvals have been recorded. On average, each dwelling supports approximately 2.2 new residents annually over the past five financial years (FY-21 to FY-25), indicating strong demand and supporting property values.

New homes are being built at an average expected construction cost of $351,000, reflecting more affordable housing options compared to regional norms. In this financial year, $2.7 million in commercial approvals have been registered, suggesting the area's residential character. When measured against Greater Sydney, Marayong shows approximately 56% of the construction activity per person and places among the 41st percentile nationally, resulting in relatively constrained buyer choice and supporting interest in existing homes. This level is also below average nationally, reflecting the area's maturity and possible planning constraints. Recent construction comprises 68.0% detached houses and 32.0% medium and high-density housing, indicating an expanding range of medium-density options creating a mix of opportunities across price brackets.

This represents a notable shift from the area's existing housing, which is currently 88.0% houses, suggesting decreasing availability of developable sites and reflecting changing lifestyles and demand for more diverse, affordable housing options. With around 403 people per dwelling approval, Marayong shows a developed market. Future projections show Marayong adding approximately 1,129 residents by 2041 (from the latest AreaSearch quarterly estimate). Current development appears well-matched to future needs, supporting steady market conditions without extreme price pressure.

In comparison, Greater Sydney saw employment grow by 2.6%, labour force expand by 2.9%, and unemployment rise by 0.3 percentage points. National employment forecasts from Sep-22 project national employment growth at 6.6% over five years and 13.7% over ten years.
