Birrong

Population growth drivers in Birrong are strong compared to national averages based on AreaSearch's ranking of recent, and medium to long-term trends

Birrong's population, as of November 2025, is estimated at around 3,454 people. This figure reflects an increase of 123 individuals since the 2021 Census, which recorded a population of 3,331 people. The change is inferred from AreaSearch's estimate of 3,459 residents following examination of the latest ERP data release by the ABS in June 2024, along with an additional 18 validated new addresses since the Census date. This results in a population density ratio of 2,878 persons per square kilometer, placing Birrong in the upper quartile relative to national locations assessed by AreaSearch. Over the past decade, from 2015 to 2025, Birrong has demonstrated resilient growth patterns with a compound annual growth rate of 1.2%, outpacing the SA3 area. Population growth for the suburb was primarily driven by overseas migration, contributing approximately 62.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For 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. By 2041, Birrong is expected to increase its population by 363 persons based on aggregated SA2-level projections, reflecting a gain of 11.2% in total over the 17-year period from 2024 to 2041.

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

Birrong has seen approximately 14 new home approvals annually over the past five financial years, totalling around 73 homes. In FY26 so far, there have been 17 approvals. On average, about 1.8 new residents arrive per year per new home between FY21 and FY25, indicating balanced supply and demand. However, this has increased to 4.4 people per dwelling over the past two financial years, suggesting growing popularity and potential undersupply. The average construction value of development projects is around $436,000, aligning with regional trends.

This year, Birrong has registered approximately $3.2 million in commercial approvals, indicating limited commercial development focus. Compared to Greater Sydney, Birrong has about three-quarters the rate of new dwelling approvals per person and ranks among the 58th percentile nationally. Currently, new building activity comprises around 57% detached dwellings and 43% attached dwellings, with a growing mix of townhouses and apartments offering various price points. This represents a significant shift from the current housing mix, which is predominantly houses (84%).

Birrong has approximately 265 people per dwelling approval, indicating a low-density market. According to AreaSearch's latest quarterly estimate, Birrong is forecasted to gain around 385 residents by 2041. With current construction levels, housing supply should meet demand adequately, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.
