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 Nov 2025, the estimated population of the Marayong statistical area (Lv2) is around 8,432. This figure represents a 7.6% increase since the 2021 Census, which reported a population of 7,834 people. The change is inferred from AreaSearch's estimation of the resident population at 7,972 in Jun 2024, based on ABS ERP data and additional validated new addresses since the Census date. This results in a density ratio of 3,111 persons per square kilometer, placing Marayong (SA2) in the upper quartile nationally according to AreaSearch assessments. The area's growth exceeded that of its SA3 region at 7.6% compared to 7.1%. Overseas migration contributed approximately 68.0% of overall population gains during recent periods.

AreaSearch is utilising ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022, and NSW State Government's SA2 level projections released in 2022 with a base year of 2021 for areas not covered by the former. 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 (SA2) is expected to grow by 887 persons to 2041, reflecting a total gain of 6.8% 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 indicates Marayong has had approximately 29 dwelling approvals per year over the past five financial years, totalling about 147 homes. In FY-26 so far, 14 approvals have been recorded. This results in an average of around two new residents per year per dwelling constructed between FY-21 and FY-25, suggesting a balanced supply and demand with stable market conditions. The average expected construction cost value for new dwellings is approximately $351,000.

There has also been $5.5 million in commercial approvals this financial year. Compared to Greater Sydney, Marayong has about two-thirds the rate of new dwelling approvals per person and ranks around the 53rd percentile nationally. New development consists mainly of standalone homes (70.0%) and townhouses or apartments (30.0%), maintaining the area's suburban character while adapting to changing lifestyle preferences and housing affordability needs, which is a notable shift from the current 88.0% houses. With around 298 people per dwelling approval, Marayong shows a developing market with an expected growth of approximately 572 residents by 2041.

Given current construction levels, housing supply should meet demand adequately, creating favourable conditions for buyers and potentially exceeding current forecasts.

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