An assessment of population growth drivers in Bilambil Heights reveals an overall ranking slightly below national averages considering recent, and medium term trends

As of Nov 2025, the Bilambil Heights statistical area (Lv2) has an estimated population of around 3,604 people. This reflects a growth of 113 individuals since the 2021 Census, which recorded a population of 3,491 people in the Bilambil Heights (SA2). The increase is inferred from AreaSearch's estimation of the resident population at 3,547 following examination of the ABS's latest ERP data release in Jun 2024, and an additional three validated new addresses since the Census date. This results in a population density ratio of approximately 423 persons per square kilometer. The Bilambil Heights (SA2) has exhibited competitive growth fundamentals with a 3.2% increase since the census, positioning it within 0.7 percentage points of the SA4 region's 3.9%. Overseas migration contributed roughly 50.0% of overall population gains during recent periods in the Bilambil Heights (SA2).

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022, and NSW State Government's SA2-level projections released in 2022 with a base year of 2021 for areas not covered by the former data. Applying growth rates by age group from these aggregations to all areas projects a population increase of just below the median of regional areas across Australia for the Bilambil Heights (SA2) between now and 2041, with an expected increase of 312 persons reflecting a total increase of approximately 9.3% over the 17 years.

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

Bilambil Heights has seen minimal construction activity with one new dwelling approved annually on average over the past five years, totalling nine. This low level of development is typical in rural areas where housing demand is modest and construction activity is limited by local demand and infrastructure capacity. It should be noted that the small sample size can significantly influence annual growth and relativity statistics.

Bilambil Heights has substantially lower development levels compared to Rest of NSW and national averages. According to AreaSearch's latest quarterly estimate, Bilambil Heights is projected to add 336 residents by 2041.

If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.
