Mount Annan

An assessment of population growth drivers in Mount Annan reveals an overall ranking slightly below national averages considering recent, and medium term trends

Based on ABS population updates and AreaSearch validations, Mount Annan's estimated population as of May 2026 is around 12,217. This reflects an increase of 433 people since the 2021 Census, which reported a population of 11,784. The change is inferred from AreaSearch's estimate of 12,201 residents following examination of ABS's latest ERP data release in June 2025 and an additional 144 validated new addresses since the Census date. This level of population equates to a density ratio of 1,194 persons per square kilometer. Population growth was primarily driven by natural growth contributing approximately 65.0% of overall gains.

AreaSearch adopts 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 are used. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Mount Annan is expected to expand by 157 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 1.1% 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 averaged around 9 new dwelling approvals annually over the past five financial years from FY18 to FY22. This totals an estimated 49 homes. As of FY26, 4 approvals have been recorded. The population has declined in recent years, yet housing supply has remained adequate relative to demand, resulting in a balanced market with good buyer choice.

New properties are constructed at an average value of $308,000, aligning with regional trends. This financial year, there have been $102,000 in commercial approvals, indicating a predominantly residential focus. Compared to Greater Sydney, Mount Annan shows substantially reduced construction, with 82.0% fewer approvals per person than the regional average. This scarcity of new homes typically strengthens demand and prices for existing properties. The area is also below the national average, suggesting its established nature and potential planning limitations. Recent construction comprises 75.0% detached dwellings and 25.0% townhouses or apartments, maintaining Mount Annan's traditional suburban character with a focus on family homes appealing to those seeking space.

This reflects a considerable change from the current housing mix of 96.0% houses, likely due to reduced availability of development sites and shifting lifestyle demands and affordability requirements. With around 1404 people per dwelling approval, Mount Annan reflects a highly mature market. Looking ahead, based on AreaSearch's latest quarterly estimate, Mount Annan is expected to grow by 141 residents through to 2041. If current development patterns continue, new housing supply should readily meet demand, offering good conditions for buyers and potentially facilitating population growth beyond current projections.
