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

Mount Annan's population is around 19,593 as of May 2026. This reflects an increase since the 2021 Census, which reported a population of 19,040 people. The change is inferred from the estimated resident population of 19,565 from the ABS in June 2025 and an additional 162 validated new addresses since the Census date. This level of population equates to a density ratio of 1,484 persons per square kilometer, above the average seen across national locations assessed by AreaSearch. Population growth was primarily driven by natural growth contributing approximately 56.8% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections, released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Future population trends anticipate lower quartile growth, with the area expected to increase by 450 persons to 2041 based on the latest annual ERP population numbers, reflecting an increase of 2.1% in total over the 16 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 received approximately 24 dwelling approvals annually over the past five financial years, totalling 122 homes. As of FY-26, 11 approvals have been recorded. Despite population decline, housing supply has remained adequate relative to demand, resulting in a balanced market with good buyer choice. New homes are being built at an average expected construction cost value of $238,000, which is below regional norms, offering more affordable housing options for purchasers.

In FY-26, $1.2 million in commercial approvals have been registered, indicating minimal commercial development activity compared to Greater Sydney, where Mount Annan has 72.0% less development activity per person. This scarcity of new properties typically strengthens demand and prices for existing properties. New development consists of 70.0% detached dwellings and 30.0% townhouses or apartments, expanding medium-density housing options and creating a mix of opportunities across price brackets. This marks a significant shift from the current housing pattern of 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 estimate an addition of 422 residents by 2041, with current construction levels expected to adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.

Future projections show Mount Annan adding 422 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.

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

Mount Annan has a skilled workforce with 2.0% unemployment as of December 2025. Employment growth over the past year was estimated at 7.2%. There are 12,748 residents in work, with an unemployment rate of 2.2%, lower than Greater Sydney's 4.2%.

Workforce participation is high at 84.1% compared to Greater Sydney's 68.8%. Census responses indicate that 32.9% of residents work from home, potentially influenced by Covid-19 lockdowns. Key employment sectors are health care & social assistance, construction, and education & training. Construction stands out with employment levels at 1.4 times the regional average.

Professional & technical services have limited presence at 5.0%, compared to the regional average of 11.5%. Employment opportunities locally may be limited, as suggested by the difference between Census working population and resident population. Between December 2024 and 2025, employment increased by 7.2% while labour force grew by 7.1%, keeping unemployment relatively stable at 2.2%. In contrast, Greater Sydney saw employment rise by 2.2%, labour force grow by 2.3%, and a marginal increase in unemployment. Jobs and Skills Australia's national employment forecasts from May-25 project overall growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Mount Annan's employment mix suggests local employment should increase by 6.2% over five years and 12.9% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not account for localised population projections.
