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 Feb 2026, the estimated population of the suburb of Marayong is around 8,430. This figure reflects an increase of 596 people since the 2021 Census, which reported a population of 7,834. The change was inferred from the resident population of 7,972 estimated by AreaSearch following examination of the latest ERP data release by the ABS (June 2024) and an additional 41 validated new addresses since the Census date. This level of population equates to a density ratio of 3,110 persons per square kilometer, placing Marayong in the upper quartile relative to national locations assessed by AreaSearch. The suburb's growth rate of 7.6% since the 2021 census exceeded that of its SA3 area (7.2%), marking it as a growth leader in the region. Overseas migration contributed approximately 68.0% of overall population gains during recent periods, driving primary growth for the area.

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 where applicable, 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 approximately 870 persons to 2041, reflecting a gain of 4.9% 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

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Marayong has experienced around 29 dwellings receiving development approval per year over the past five financial years. This totals an estimated 145 homes from FY-20 to FY-24. So far in FY-26, 22 approvals have been recorded. On average, each dwelling accommodates approximately two new residents per year over these five years, indicating healthy demand that supports property values.

New homes are being built at an average construction cost value of $351,000. In this financial year, there have also been $5.5 million in commercial approvals, reflecting the area's primarily residential nature. Compared to Greater Sydney, Marayong shows approximately 62% of the construction activity per person and ranks among the 52nd percentile of areas assessed nationally, suggesting its established nature and potential planning limitations. New development consists of 71.0% detached dwellings and 29.0% medium and high-density housing, maintaining Marayong's traditional suburban character focused on family homes. This shift from the area's existing housing (currently 88.0% houses) indicates decreasing availability of developable sites and reflects changing lifestyles and demand for more diverse, affordable housing options.

With around 316 people per approval, Marayong reflects a transitioning market. According to AreaSearch's latest quarterly estimate, the area is expected to grow by 412 residents through to 2041. With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.

Marayong has very high levels of nearby infrastructure activity, ranking in the top 10% nationally

In the 12-month period, employment increased by 3.4%, labour force grew by 2.8%, and unemployment fell by 0.5 percentage points. Greater Sydney recorded employment growth of 2.2% with marginal unemployment rise. Jobs and Skills Australia's national employment forecasts from May-25 project national employment expansion at 6.6% over five years and 13.7% over ten years. Applying these projections to Marayong's employment mix suggests local employment should increase by 6.4% over five years and 13.4% over ten years, though this is a simple weighting extrapolation for illustrative purposes only.
