This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Population
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 AreaSearch's analysis of ABS population updates and new addresses validated since the Census, as of May 2026, the estimated population of Bilgola Plateau is around 3,652 people. This figure reflects an increase of 2 people (0.1%) from the 2021 Census population of 3,650 people. The change was inferred from AreaSearch's estimate of a resident population of 3,652 following examination of the latest ERP data release by the ABS in June 2025 and an additional 6 validated new addresses since the Census date. This level of population results in a density ratio of 2,627 persons per square kilometer, placing Bilgola Plateau in the upper quartile relative to national locations assessed by AreaSearch. The suburb's 0.1% growth since census positions it within 2.4 percentage points of the SA3 area (2.5%), indicating competitive growth fundamentals. Overseas migration primarily drove population growth for the area, contributing approximately 68.0% of overall population gains during recent periods.
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 where applicable, released in 2022 with a base year of 2021. Considering these projections, lower quartile growth is anticipated nationally by 2041, with Bilgola Plateau expected to increase by 63 persons over the period, reflecting an overall increase of 1.7%.

Development
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 for Bilgola Plateau shows approximately 10 residential properties granted approval annually over the past five financial years to FY26, totalling an estimated 53 homes. As of FY26, 1 approval has been recorded. The population has fallen during this period, but housing supply has remained adequate relative to demand, maintaining a balanced market with good buyer choice. New homes are being built at an average expected construction cost value of $1,012,000, indicating developers target the premium market segment with higher-end properties.
This financial year has seen $42,000 in commercial approvals, reflecting Bilgola Plateau's residential nature. Compared to Greater Sydney, Bilgola Plateau maintains similar construction rates per person, preserving market equilibrium consistent with surrounding areas. However, this activity is below the national average, suggesting the area's established nature and potential planning limitations. Recent building activity consists entirely of standalone homes, preserving Bilgola Plateau's suburban nature and attracting space-seeking buyers.
With around 1824 people per dwelling approval, it reflects a highly mature market. AreaSearch's latest quarterly estimate projects Bilgola Plateau to add 63 residents by 2041. Based on current development patterns, new housing supply should readily meet demand, offering good conditions for buyers and potentially facilitating population growth beyond current projections.
