Mount Annan
Statistical Area - sa2

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 was approximately 19,482 as of November 2025. This figure represents an increase of 442 people since the 2021 Census, which reported a population of 19,040. The change is inferred from ABS data showing an 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 average national locations assessed by AreaSearch. Natural growth contributed approximately 64.7% 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, NSW State Government's SA2 level projections released in 2022 with a base year of 2021 are used. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Future population trends suggest lower quartile growth, with the area expected to increase by 528 persons to 2041 based on latest numbers, reflecting a total increase of 2.8% over 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 received approximately 24 dwelling approvals annually over the past five financial years, totalling 122 homes. In FY-26 so far, three approvals have been recorded. The area's population has declined, yet 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 of $238,000, which is below regional norms, reflecting more affordable housing options.

This financial year, $1.2 million in commercial approvals have been registered, indicating minimal commercial development activity. Compared to Greater Sydney, Mount Annan has significantly less development activity, at 72.0% below the regional average per person. This scarcity of new properties typically strengthens demand and prices for existing properties. Nationally, this is also below average, suggesting the area's maturity and possible planning constraints. New developments consist of 70.0% detached dwellings and 30.0% townhouses or apartments, expanding medium-density options and creating a mix of opportunities across price brackets. This marks a significant shift from existing housing patterns, which are currently 97.0% houses, likely due to diminishing developable land availability and evolving lifestyle preferences.

Mount Annan reflects a highly mature market with around 1014 people per dwelling approval. Future projections indicate Mount Annan adding 547 residents by 2041. With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.
