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

The population of Mount Annan is estimated at approximately 12,061 as of February 2026. This figure reflects an increase of 277 people since the Census in 2021, which recorded a population of 11,784. The change was inferred from AreaSearch's estimation of the resident population at 11,955 following examination of ABS data released in June 2024 and an additional 142 validated new addresses since the Census date. This results in a density ratio of 1,179 persons per square kilometer, which is comparable to averages seen across other locations assessed by AreaSearch. Natural growth contributed approximately 65.0% of overall population gains during recent periods.

Population projections for Mount Annan are based on ABS/Geoscience Australia data released in 2024 with a base year of 2022, and NSW State Government's SA2 level projections released in 2022 with a base year of 2021 for areas not covered by the former. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Future population dynamics anticipate lower quartile growth, with an expected expansion of 194 persons in Mount Annan to reach a total of approximately 12,255 by 2041, reflecting an increase of 1.4% over the 17-year period.

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 in Mount Annan shows approximately 9 residential properties granted approval per year over the past 5 financial years, totalling an estimated 49 homes. So far in FY26, 2 approvals have been recorded. The population decline in recent years has resulted in adequate housing supply relative to demand, creating a balanced market with good buyer choice. New properties are constructed at an average value of $308,000, aligning with regional trends.

There have also been $102,000 in commercial approvals this financial year, indicating a predominantly residential focus. Compared to Greater Sydney, Mount Annan shows significantly reduced construction (82.0% below the regional average per person), which typically strengthens demand and prices for existing properties. This level is also under the national average, suggesting the area's 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 shows a considerable shift from the current housing mix (currently 96.0% houses), reflecting reduced availability of development sites and addressing shifting lifestyle demands and affordability requirements. With around 1413 people per dwelling approval, Mount Annan reflects a highly mature market.

Looking ahead, AreaSearch estimates Mount Annan will grow by 175 residents through to 2041. Based on current development patterns, new housing supply should readily meet demand, offering good conditions for buyers and potentially facilitating population growth beyond current projections.
