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, as of November 2025, is approximately 19,482. This figure represents an increase of 442 people since the 2021 Census, which recorded a population of 19,040. The change was inferred from the estimated resident population of 19,501 in June 2024 and an additional 153 validated new addresses since the Census date. This results in a population density ratio of 1,475 persons per square kilometer, higher than the average across national locations assessed by AreaSearch. Natural growth contributed approximately 64.7% of overall population gains during recent periods.

AreaSearch is using 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 utilizes 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 indicate lower quartile growth is anticipated, with the area expected to increase by 528 persons to 2041 based on the latest annual ERP population numbers, reflecting a total increase of 2.8% 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 seen approximately 24 dwelling approvals per year over the past five financial years, totalling 122 homes. As of FY-26, there have been 4 recorded approvals. Despite population decline in the area, housing supply has remained adequate relative to demand, resulting in a balanced market with good buyer choice. The average construction cost for new homes is $238,000, which is below regional norms, offering more affordable housing options.

In FY-26, there have been $1.2 million worth of commercial approvals registered, indicating minimal commercial development activity compared to Greater Sydney, where Mount Annan has 72.0% less development activity per person. This scarcity typically strengthens demand and prices for existing properties. New development consists of 70.0% detached dwellings and 30.0% townhouses or apartments, marking a significant shift from the current housing pattern of 97.0% houses, suggesting diminishing developable land availability and responding to evolving lifestyle preferences and affordability needs. With around 1014 people per dwelling approval, Mount Annan reflects a highly mature market. According to AreaSearch's latest quarterly estimate, Mount Annan is projected to add 547 residents by 2041. Current construction levels suggest that housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.

Future projections show Mount Annan adding 547 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.
