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

Mount Annan's population, as of Nov 2025, is estimated at around 12,059. This reflects an increase of 275 people since the 2021 Census, which reported a population of 11,784. The change was inferred from AreaSearch's estimate of 11,955 residents following examination of ABS ERP data release in June 2024 and additional validated new addresses since the Census date. This level of population results in a density ratio of 1,178 persons per square kilometer, comparable to averages seen across locations assessed by AreaSearch. Natural growth contributed approximately 65.0% of overall population gains during recent periods.

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 are used, 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. By 2041, the Mount Annan statistical area (Lv2) is expected to expand by 192 persons based on aggregated SA2-level projections, reflecting an increase of 1.4% in total 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

AreaSearch analysis of ABS building approval numbers shows Mount Annan recorded around 9 residential properties granted approval per year over the past 5 financial years ending FY26, totalling an estimated 49 homes. As of FY26, 2 approvals have been recorded. Population decline in recent years has maintained adequate housing supply relative to demand, creating a balanced market with good buyer choice. Average construction value for new properties is $308,000, aligning with regional trends.

Commercial approvals this financial year totalled $102,000, indicating a predominantly residential focus. Mount Annan shows reduced construction compared to Greater Sydney (82.0% below average per person), which typically strengthens demand and prices for existing properties. This level is also under the national average, suggesting established nature and potential planning limitations. Recent construction comprises 75.0% detached dwellings and 25.0% townhouses or apartments, maintaining Mount Annan's suburban character focused on family homes. This shows a shift from the current housing mix of 96.0% houses, reflecting reduced development sites availability and changing lifestyle demands. With around 1413 people per dwelling approval, Mount Annan reflects a mature market.

AreaSearch estimates Mount Annan will grow by 173 residents through to 2041. Based on current development patterns, new housing supply should meet demand, offering good conditions for buyers and potentially facilitating population growth beyond projections.
