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 19,482 as of Aug 2025. This reflects an increase from 19,040 people in the 2021 Census. The ABS estimated resident population was 19,504 by Jun 2024, with an additional 152 validated new addresses since the Census date.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area released in 2024 with 2022 as the base year. For areas not covered by this data, NSW State Government's SA2 level projections released in 2022 with 2021 as the base year are used. 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 an expected increase of 528 persons to 2041 based on latest 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 received approximately 24 dwelling approvals annually over the past five financial years, totalling 122 homes. As of FY-26, there has been one recorded approval. The area has experienced population decline, yet housing supply has remained adequate relative to demand, resulting in a balanced market with diverse buyer options. New homes are being constructed at an average cost of $308,000, below regional norms, offering more affordable housing choices.

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, which typically strengthens demand and prices for existing properties. This is also below national averages, suggesting mature market conditions and possible planning constraints. New developments consist of 70.0% detached dwellings and 30.0% townhouses or apartments, expanding medium-density options and catering to various price brackets. This marks a significant shift from the current housing pattern, which is predominantly houses (97.0%). This trend may indicate diminishing developable land availability and responds to evolving lifestyle preferences and affordability needs.

With around 1014 people per dwelling approval, Mount Annan reflects a highly mature market. Future projections estimate an increase of 547 residents by 2041. Current construction levels are expected to meet housing demand adequately, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.
