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
Bonnet Bay 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 analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch, the suburb of Bonnet Bay's population is estimated at around 2,314 as of May 2026. This reflects an increase of 76 people (3.4%) since the 2021 Census, which reported a population of 2,238 people. The change is inferred from the resident population of 2,309, estimated by AreaSearch following examination of the latest ERP data release by the ABS on June 2025 and address validation since the Census date. This level of population equates to a density ratio of 2,047 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Bonnet Bay's 3.4% growth since the 2021 census exceeded the SA3 area (3.1%), marking it as a growth leader in the region. Population growth for the suburb was primarily driven by overseas migration that contributed approximately 63.0% 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 any SA2 areas not covered by this data, AreaSearch is utilising the NSW State Government's SA2 level projections, as released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are also applied to all areas for years 2032 to 2041. Anticipating future population dynamics, a population increase just below the median of statistical areas across the nation is expected, with the suburb expected to grow by 129 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 5.4% in total over the 16 years.
Frequently Asked Questions - Population
Development
The level of residential development activity in Bonnet Bay is very low in comparison to the average area assessed nationally by AreaSearch
Bonnet Bay has recorded only 2 dwelling approvals in the past five years. This indicates a fully developed suburb with limited new construction opportunities. The scarcity of new supply supports demand for established properties, potentially contributing to price stability.
Compared to Greater Sydney, Bonnet Bay has significantly lower building activity. This scarcity typically strengthens demand and prices for existing properties, although building activity has increased in recent years. Nationally, this is also below average, suggesting the area's maturity and possible planning constraints.

Sydney Metro City and Southwest
A 30km metro rail extension connecting Chatswood to Bankstown via the Sydney CBD. The Chatswood to Sydenham section, featuring a new harbour crossing and seven CBD stations, opened on 19 August 2024. The final stage involves converting the 13.5km T3 Bankstown Line to metro standards between Sydenham and Bankstown, upgrading 11 stations with platform screen doors, lifts, and full accessibility. The T3 line closed in September 2024 to enable conversion works. Following delays caused by over 130 days of industrial action, the Sydenham to Bankstown section is scheduled to open in the second half of 2026. End-to-end high-speed testing at up to 100km/h commenced in November 2025, and the first full-length test run from Tallawong to Bankstown was completed in January 2026. The Bankstown Station transit interchange and community precinct opened in March 2026. When complete, the M1 Line will span 66km with 31 stations, running every four minutes in peak.

As of May 2026, the policy is fully operational following the phased rollout of dual occupancy provisions in July 2024 and mid-rise apartment provisions in early 2025. Recent updates include refined floor space ratios (FSR) and non-refusal standards to streamline local council assessments.
