Mortdale

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

As of Nov 2025, the Mortdale statistical area's population is estimated at around 12,003 people. This reflects an increase of 1,258 individuals since the 2021 Census, which reported a population of 10,745. The change was inferred from AreaSearch's estimate of the resident population at 11,769 following examination of the ABS's latest ERP data release in June 2024 and an additional 105 validated new addresses since the Census date. This results in a population density ratio of 4,096 persons per square kilometer, placing Mortdale among the top 10% of national locations assessed by AreaSearch. The Mortdale (SA2) experienced a growth rate of 11.7% between the 2021 Census and Nov 2025, exceeding both its SA4 region's growth rate of 7.5% and the state's rate. This growth was primarily driven by overseas migration contributing approximately 83.0% of overall population gains during recent periods.

AreaSearch's projections for the Mortdale (SA2) are based on ABS/Geoscience Australia data released in 2024 with a 2022 base year, and NSW State Government SA2-level projections released in 2022 using a 2021 base year for areas not covered by ABS data. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. By 2041, the Mortdale (SA2) is projected to increase by approximately 1,046 persons based on aggregated SA2-level projections, reflecting an overall increase of around 0.9% over the 17-year period.

Residential development activity is lower than average in Mortdale according to AreaSearch's national comparison of local real estate markets

AreaSearch analysis of ABS building approval numbers indicates Mortdale has around 50 dwelling approvals annually. Between FY-21 and FY-25, approximately 251 homes were approved, with another 67 in FY-26 so far. Despite population decline, housing supply has been adequate relative to demand, creating a balanced market with good buyer choice.

New homes are targeted at the premium segment, with an average construction value of $615,000. Commercial approvals this year totalled $753,000, reflecting Mortdale's residential nature. Compared to Greater Sydney, Mortdale has elevated construction activity (21.0% above regional average per person over the past five years), preserving buyer options while sustaining demand. Recent construction comprises 46.0% detached houses and 54.0% townhouses or apartments, promoting affordable entry points for downsizers, investors, and first-home buyers.

With around 279 people per dwelling approval, Mortdale shows a developing market. By 2041, Mortdale is projected to grow by 109 residents. Current development patterns suggest new housing supply will meet demand, offering favourable conditions for buyers and potentially facilitating population growth beyond current projections.
