Birchgrove

Birchgrove is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch, Birchgrove's population is estimated at around 3,349 as of Feb 2026. This reflects an increase of 121 people (3.7%) since the 2021 Census, which reported a population of 3,228 people. The change is inferred from the resident population of 3,325 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and address validation since the Census date. This level of population equates to a density ratio of 5,676 persons per square kilometer, placing Birchgrove in the top 10% of national locations assessed by AreaSearch, indicating high demand for land in the area. Birchgrove's growth rate of 3.7% since census is within 0.1 percentage points of the SA3 area (3.8%), demonstrating competitive growth fundamentals. Overseas migration contributed approximately 72.0% of overall population gains during recent periods, driving primary population growth for the suburb.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections 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. Considering projected demographic shifts, Birchgrove is expected to increase by approximately 250 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 6.8% in total over the 17 years.

The level of residential development activity in Birchgrove is very low in comparison to the average area assessed nationally by AreaSearch

Birchgrove has averaged approximately one new dwelling approval per year. Between financial years 2021 and 2025, around six homes were approved, with one more approved in the current financial year 2026. The area's population decline suggests that new supply may be meeting demand, offering buyers good choice.

New properties are constructed at an average expected cost of $1,278,000, indicating a focus on premium segment upmarket properties. This financial year has seen $4.3 million in commercial approvals, suggesting limited commercial development focus compared to Greater Sydney, where construction is 88.0% higher per person. Birchgrove's scarcity of new properties typically strengthens demand and prices for existing properties, though recent construction activity has intensified. Nationally, the area's construction activity is below average, reflecting its maturity and possible planning constraints. Recent development has been entirely detached dwellings, preserving the area's suburban nature with an emphasis on space-seeking buyers.

Developers are constructing more detached housing than the existing pattern implies (28.0% at Census), suggesting strong demand for family homes amid densification trends. Birchgrove has approximately 2183 people per dwelling approval, indicating an established market. By 2041, Birchgrove is expected to grow by 226 residents (from the latest AreaSearch quarterly estimate). At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.
