Population
An assessment of population growth drivers in Balgowlah Heights reveals an overall ranking slightly below national averages considering recent, and medium term trends
As of May 2026, the population of the suburb of Balgowlah Heights is estimated to be around 3464 people. This reflects a decrease from the 2021 Census figure of 3546 people, indicating an 82 person drop (approximately 2.3%). The latest estimate is based on AreaSearch's examination of the ABS' ERP data release from June 2025 and validation of four new addresses since the Census date. This results in a population density ratio of approximately 2061 persons per square kilometer, higher than the average seen across national locations assessed by AreaSearch. Overseas migration was the primary driver for population growth in the area, contributing around 78% of overall population gains during recent periods.
AreaSearch's projections for Balgowlah Heights are based on ABS/Geoscience Australia figures released in 2024 with a 2022 base year for covered SA2 areas. For non-covered areas, NSW State Government's SA2 level projections from 2022 using a 2021 base year are applied. Growth rates by age group from these aggregations are used to project population changes from 2032 to 2041. Based on aggregated SA2-level projections, the suburb of Balgowlah Heights is expected to grow by approximately 21 persons by 2041, reflecting a total growth rate of around 0.6% over the 16-year period. This anticipates lower quartile growth trends for national areas moving forward in demographic trends.

Development
The level of residential development activity in Balgowlah Heights is very low in comparison to the average area assessed nationally by AreaSearch
Balgowlah Heights has seen approximately seven new homes approved annually based on AreaSearch analysis of ABS building approval numbers. Between FY-21 and FY-25, around 35 homes were approved, with five more approved in FY-26. Over these years, an average of zero people moved to the area per dwelling built, indicating that new supply is meeting or exceeding demand.
The average construction cost value of new properties is $965,000, suggesting a focus on the premium market. This financial year, $3.6 million in commercial approvals have been registered, reflecting the area's residential character. Comparatively, Balgowlah Heights has 15.0% less new development per person than Greater Sydney and ranks at the 24th percentile nationally when assessed for buyer choice. This suggests relatively constrained buyer choice, driving interest in existing dwellings. The new building activity shows a split of 50.0% detached houses and 50.0% medium and high-density housing, offering affordable entry pathways and attracting downsizers, investors, and first-time purchasers. The area has around 647 people per dwelling approval, reflecting a highly mature market.
Population forecasts indicate Balgowlah Heights will gain 21 residents by 2041. Given current development patterns, new housing supply should readily meet demand, offering good conditions for buyers and potentially facilitating population growth beyond current projections.
