Mount Annan

Mount Annan is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

Based on AreaSearch's analysis, Mount Annan's population is around 19,693 as of Feb 2026. This reflects an increase of 653 people (3.4%) since the 2021 Census, which reported a population of 19,040 people. The change is inferred from the estimated resident population of 19,501 from the ABS as of June 2024 and an additional 154 validated new addresses since the Census date. This population level equates to a density ratio of 1,491 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Population growth for the area was primarily driven by natural growth, which contributed approximately 64.7% of overall population gains during recent periods.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, AreaSearch utilizes the NSW State Government's SA2 level projections, as released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are also applied to all areas for years 2032 to 2041. As we examine future population trends, lower quartile growth of national statistical areas is anticipated, with the area expected to increase by 528 persons to 2041 based on the latest annual ERP population numbers, reflecting an increase of 1.7% in total over the 17 years.

The level of residential development activity in Mount Annan is very low in comparison to the average area assessed nationally by AreaSearch

Mount Annan has experienced around 24 dwellings receiving development approval each year, totalling 122 homes over the past 5 financial years. So far in FY-26, 7 approvals have been recorded. As the area has experienced population decline, housing supply has remained adequate relative to demand, creating a well-balanced market with good buyer choice, while new homes are being built at an average value of $238,000—below regional norms—reflecting more affordable housing options for purchasers. Additionally, $1.2 million in commercial approvals have been registered this financial year, indicating minimal commercial development activity.

When measured against Greater Sydney, Mount Annan has significantly less development activity (72.0% below regional average per person). This scarcity of new properties typically strengthens demand and prices for existing properties. This is also below average nationally, reflecting the area's maturity and pointing to possible planning constraints. New development consists of 70.0% detached dwellings and 30.0% townhouses or apartments, showing an expanding range of medium-density options creating a mix of opportunities across price brackets, from traditional family housing to more affordable compact alternatives. This marks a significant departure from existing housing patterns (currently 97.0% houses), suggesting diminishing developable land availability and responding to evolving lifestyle preferences and housing affordability needs. With around 1014 people per dwelling approval, Mount Annan reflects a highly mature market.

Future projections show Mount Annan adding 336 residents by 2041 (from 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.

Mount Annan has strong levels of nearby infrastructure activity, ranking in the top 40% nationally

The exceptional employment performance in Mount Annan places it among Australia's strongest labour markets

Mount Annan possesses a skilled workforce, with essential services sectors well represented, an unemployment rate of just 2.0%, and 7.2% in estimated employment growth over the past year. As of December 2025, 12,748 residents are in work while the unemployment rate is 2.2% below Greater Sydney's rate of 4.2%, and workforce participation is well beyond standard (85.0% compared to Greater Sydney's 70.2%). Based on Census responses, a high 32.9% of residents were found to work from home, though Covid-19 lockdown impacts should be considered.

Employment among residents is concentrated in health care & social assistance, construction, and education & training. The area demonstrates a particularly notable concentration in construction, with employment levels at 1.4 times the regional average. Meanwhile, professional & technical services have a limited presence with 5.0% employment compared to 11.5% regionally. The area appears to offer limited employment opportunities locally, as indicated by the count of the Census working population versus the resident population.

Based on AreaSearch analysis of SALM and ABS data, the 12-month period saw employment increasing by 7.2% alongside the labour force increasing by 7.1%, keeping the unemployment rate relatively stable. This contrasts with Greater Sydney, where employment rose by 2.2%, the labour force grew by 2.3%, and unemployment rose marginally. Jobs and Skills Australia's national employment forecasts from May-25 can offer further insight into potential future demand within Mount Annan. These projections, covering five and ten-year periods, have been mapped against the local employment profile to estimate growth patterns. While national employment is forecast to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly between industry sectors. Applying these industry-specific projections to Mount Annan's employment mix suggests local employment should increase by 6.2% over five years and 12.9% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections).
