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 19,482 as of Aug 2025. This was an increase of 442 people from the 2021 Census figure of 19,040. The change was inferred from ABS' estimated resident population of 19,504 in June 2024 and additional validated new addresses since the Census date. Population density was 1,475 persons per square kilometer, above national averages assessed by AreaSearch. Natural growth contributed approximately 64.7% to recent overall population gains.

AreaSearch adopted ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022. For areas not covered, NSW State Government's SA2 level projections released in 2022 with a base year of 2021 were used. Growth rates by age group from these aggregations were 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. As of FY-26, there is one recorded approval. The area's population decline has resulted in adequate housing supply relative to demand, maintaining a balanced market with good buyer choice. New homes are being built at an average cost of $308,000, below regional norms, offering more affordable housing options.

In FY-26, $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, 72.0% below the regional average per person. This scarcity of new properties typically strengthens demand and prices for existing properties, reflecting the area's maturity and possible planning constraints. New development consists of 70.0% detached dwellings and 30.0% townhouses or apartments, expanding medium-density options and creating a mix of housing opportunities across price brackets. This marks a significant shift 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 indicate an addition of 547 residents by 2041. Current construction levels should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.
