Birrong

Population growth drivers in Birrong are slightly above average based on AreaSearch's ranking of recent, and medium term trends

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch since the Census, Birrong's population is estimated at around 3,597 as of Feb 2026. This reflects an increase of 266 people (8.0%) since the 2021 Census, which reported a population of 3,331 people. The change is inferred from the resident population of 3,461 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 16 validated new addresses since the Census date. This level of population equates to a density ratio of 2,997 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Birrong's 8.0% growth since the 2021 census exceeded the SA4 region (7.6%), along with the state, marking it as a growth leader in the region. Population growth for the area was primarily driven by overseas migration that contributed approximately 62.0% 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. For any SA2 areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections, released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Looking at population projections moving forward, a population increase just below the median of statistical areas analysed by AreaSearch is expected. The suburb of Birrong is expected to grow by 365 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 6.4% in total over the 17 years.

Residential development activity is lower than average in Birrong according to AreaSearch's national comparison of local real estate markets

Birrong has seen approximately 15 dwelling approvals annually based on AreaSearch's analysis of ABS data. Between FY-21 and FY-25, around 79 homes were approved, with an additional 23 in FY-26 so far. On average, each new dwelling has accommodated about 1.6 residents over the past five years, indicating balanced supply and demand. However, this figure has risen to 5.4 people per dwelling over the last two years, suggesting increasing demand.

The average construction value of developments is $436,000, slightly above the regional average. This year alone, Birrong has seen $4.2 million in commercial development approvals. Comparatively, Birrong has 17.0% less new development per person than Greater Sydney but ranks at the 49th percentile nationally for housing choices. New developments consist of 56.0% detached houses and 44.0% attached dwellings, marking a shift from the current 84.0% houses.

This change may indicate decreasing developable land availability and evolving lifestyle preferences. Birrong has around 328 people per approval, reflecting a transitioning market. By 2041, AreaSearch estimates Birrong's population will grow by 229 residents. At current development rates, new housing supply should meet demand comfortably, providing good conditions for buyers and potentially supporting growth beyond current projections.
