Sans Souci

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

As of November 2025, the estimated population of Sans Souci is around 11,105. This reflects an increase of 241 people since the 2021 Census, which reported a population of 10,864. The change is inferred from AreaSearch's estimation of the resident population at 11,079 in June 2024, based on ABS ERP data and an additional 67 validated new addresses since the Census date. This results in a density ratio of 3,617 persons per square kilometer, placing Sans Souci in the upper quartile relative to national locations assessed by AreaSearch. Overseas migration contributed approximately 76.0% of overall population gains during recent periods.

For future projections until 2041, AreaSearch is utilising ABS/Geoscience Australia projections for SA2 areas released in 2024 with a 2022 base year, and NSW State Government's SA2 level projections for areas not covered by this data, released in 2022 with a 2021 base year. Growth rates by age group are applied to all areas from these aggregations for years 2032 to 2041. Based on aggregated SA2-level projections, Sans Souci is expected to increase by 364 persons to 2041, reflecting a total increase of 2.4% over the 17-year period.

AreaSearch analysis of residential development drivers sees Sans Souci recording a relatively average level of approval activity when compared to local markets analysed countrywide

Over the past five financial years, from FY21 to FY25, approximately 252 homes were approved, with an additional 25 approved in FY26 so far. Despite population decline, housing supply has remained adequate relative to demand, resulting in a balanced market with good buyer choice.

New dwellings are developed at an average cost of $739,000, indicating a focus on the premium segment. This year, there have been $11.9 million in commercial approvals, suggesting steady commercial investment activity. Compared to Greater Sydney, Sans Souci records 18.0% less building activity per person and ranks at the 68th percentile nationally among assessed areas. New development consists of 43.0% standalone homes and 57.0% townhouses or apartments, favouring denser development that appeals to downsizers, investors, and entry-level buyers.

The area has approximately 201 people per dwelling approval, indicating a low density market. AreaSearch's latest quarterly estimate projects Sans Souci's population to grow by 264 residents by 2041. With current construction levels, housing supply is expected to meet demand adequately, creating favourable conditions for buyers and potentially enabling growth that exceeds current forecasts.
