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 population of Marayong is estimated at around 8,430 people. This reflects an increase of 596 people since the 2021 Census, which reported a population of 7,834 people. The change was inferred from AreaSearch's resident population estimate of 7,972 following examination of ABS' latest ERP data release in 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. Marayong's growth rate of 7.6% since the 2021 census exceeded the SA3 area's growth rate of 7.2%, marking it as a growth leader in the region. 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. For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections, 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 884 persons to 2041, reflecting a gain of 6.8% in total over the 17 years.

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 147 homes from FY-20 to FY-25. So far in FY-26, 14 approvals have been recorded. Over these five years, there has been an average of two new residents per year per dwelling constructed.

The supply and demand appear well-balanced, creating stable market conditions. New dwellings are developed at an average value of $351,000. In FY-26, there have also been $5.5 million in commercial approvals, suggesting the area's residential character. Compared to Greater Sydney, Marayong has around two-thirds the rate of new dwelling approvals per person and places among the 53rd percentile of areas assessed nationally.

New development consists of 70.0% standalone homes and 30.0% townhouses or apartments, preserving the area's suburban nature with an emphasis on detached housing attracting space-seeking buyers. This marks a significant departure from existing housing patterns which are currently 88.0% houses, suggesting diminishing developable land availability and responding to evolving lifestyle preferences and housing affordability needs. With around 298 people per dwelling approval, Marayong shows a developing market. Looking ahead, Marayong is expected to grow by 576 residents through to 2041 according to the latest AreaSearch quarterly estimate. With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.

The employment landscape in Marayong shows performance that lags behind national averages across key labour market indicators

Marayong has a well-educated workforce with diverse sector representation. Its unemployment rate was 4.8% in the past year, with an estimated employment growth of 5.1%. As of September 2025, 4,103 residents are employed, and the unemployment rate is 0.7% higher than Greater Sydney's rate of 4.2%.

Workforce participation is lower at 66.9%, compared to Greater Sydney's 70.0%. A high proportion of residents work from home (29.9%), possibly due to Covid-19 lockdown impacts. Dominant employment sectors include health care & social assistance, transport, postal & warehousing, and retail trade. Marayong has a strong specialization in transport, postal & warehousing (2.2 times the regional level), but professional & technical services are under-represented (6.1% vs Greater Sydney's 11.5%).

Local employment opportunities appear limited, with fewer working residents than the resident population. Between September 2024 and September 2025, employment increased by 5.1%, while labour force grew by 4.3%, causing unemployment to fall by 0.8 percentage points. In contrast, Greater Sydney's employment grew by 2.1%, labour force expanded by 2.4%, and unemployment rose by 0.2 percentage points. National employment forecasts from Jobs and Skills Australia (May-25) project national employment growth of 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 simplified extrapolation for illustrative purposes only.
