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

As of November 2025, Mount Annan's population is estimated at around 12,113. This reflects an increase of 329 people since the 2021 Census, which reported a population of 11,784. The change is inferred from AreaSearch's estimate of 12,126 residents following examination of the latest ABS ERP data release in June 2024 and an additional 142 validated new addresses since the Census date. This level of population equates to a density ratio of 1,184 persons per square kilometer. Natural growth contributed approximately 65.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year, and NSW State Government's SA2 level projections where applicable, released in 2022 with 2021 as the base year. Considering these projections, the suburb is expected to expand by 192 persons to 2041, reflecting a gain of 1.0% 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

Mount Annan recorded approximately 11 residential properties granted approval annually over the past five financial years ending FY26. This totals an estimated 59 homes. In FY26 so far, 2 approvals have been recorded. Despite a population decline, development activity has been adequate relative to other areas.

New properties are constructed at an average expected construction cost of $308,000, below regional norms, offering more affordable housing options. Additionally, $1.1 million in commercial development approvals have been recorded this financial year, indicating a predominantly residential focus. Compared to Greater Sydney, Mount Annan shows substantially reduced construction activity, with 78.0% fewer approvals per person than the regional average. This scarcity of new properties typically strengthens demand and prices for existing properties, although building activity has accelerated in recent years. Recent construction comprises 73.0% detached houses and 27.0% medium and high-density housing, maintaining Mount Annan's traditional suburban character with a focus on family homes appealing to those seeking space. This shows a considerable change from the current housing mix, which is currently 96.0% houses, reflecting reduced availability of development sites and addressing shifting lifestyle demands and affordability requirements.

At around 858 people per approval, Mount Annan shows a mature, established area with an expected population growth of 119 residents through to 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
