Mortlake (NSW)

Population growth drivers in Mortlake are strong compared to national averages based on AreaSearch's ranking of recent, and medium to long-term trends

The Mortlake (NSW) statistical area (Lv2), based on ABS population updates and AreaSearch validations, had an estimated population of around 2,037 as of November 2025. This figure reflects a growth of 83 people since the 2021 Census, which reported a population of 1,954. The increase is inferred from AreaSearch's estimation of 2,035 residents following examination of ABS's latest ERP data release in June 2024 and four additional validated new addresses since the Census date. This results in a population density ratio of 8,487 persons per square kilometer, placing Mortlake (NSW) within the top 10% nationally according to AreaSearch. The area's 4.2% growth since the census is competitive with its SA3 area's 5.4%, indicating strong fundamentals. Overseas migration contributed approximately 83.0% of overall population gains during recent periods.

For projections, AreaSearch uses ABS/Geoscience Australia data for each SA2 area released in 2024 with a base year of 2022. By 2041, the Mortlake (NSW) (SA2) population is expected to decline by 98 persons according to these projections. However, specific age cohorts are anticipated to grow, notably the 75-84 age group, projected to increase by 55 people over this period.
