Bilgola Plateau

Bilgola Plateau 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 ABS population updates and AreaSearch validation, as of November 2025, Bilgola Plateau's estimated population is around 3677. This reflects an increase of 27 people since the 2021 Census, which reported a population of 3650. The change was inferred from AreaSearch's estimation of the resident population at 3660 following examination of ABS' latest ERP data release in June 2024 and six additional validated new addresses since the Census date. This level of population results in a density ratio of 2645 persons per square kilometer, placing Bilgola Plateau in the upper quartile relative to national locations assessed by AreaSearch. The area's growth rate of 0.7% since census is within 1.1 percentage points of its SA3 area (1.8%), indicating competitive growth fundamentals. Overseas migration contributed approximately 68.0% of overall population gains during recent periods, driving primary growth for the Bilgola Plateau statistical area (Lv2).

AreaSearch adopts 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 for areas not covered by this data, 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. Looking ahead, lower quartile growth is anticipated nationally, with Bilgola Plateau expected to grow by 66 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 2.8% in total over the 17 years.

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

AreaSearch analysis of ABS building approval numbers allocated from statistical area data shows Bilgola Plateau experienced around 10 dwelling approvals annually over the past five financial years, totalling approximately 54 homes. As of FY26, one approval has been recorded. Despite population decline during this period, development activity has remained adequate relative to population changes, benefiting buyers. New properties are constructed at an average value of $1,012,000, indicating a focus on the premium segment with upmarket properties.

In FY26, $42,000 in commercial approvals have been registered, reflecting Bilgola Plateau's residential nature. Compared to Greater Sydney, Bilgola Plateau exhibits comparable development activity per person, supporting market stability aligned with regional patterns. However, activity is lower than national levels, suggesting market maturity and possible development constraints. All new construction consists of standalone homes, preserving the area's suburban character and attracting space-seeking buyers, with around 1478 people per approval.

AreaSearch forecasts indicate Bilgola Plateau will gain 102 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.
