DemographicsPopulation Growth in Oyster Bay

Table Chart PROFILE FAQ

Oyster Bay has an estimated 6,000 residents, up from 5,689 at the 2021 Census — a change of 311 people, or 5.5%. Growth has averaged 0.5% a year over five years. Overseas migration accounts for 63.0% of that increase. That puts 2,804 residents on each square kilometre. Population is estimated from ABS Estimated Resident Population releases and GNAF address data, re-based from the 2021 Census and updated annually.

Detail

According to AreaSearch evaluations integrating ABS regional population revisions with newly validated addresses post-dating the Census, the suburb of Oyster Bay has an estimated resident tally of approximately 6,000 as of Aug 2026. This equates to an expansion of 311 people (5.5%) compared to the 2021 Census count of 5,689 people. This upward trajectory is derived from an Estimated Resident Population (ERP) of 5,994 published in the June 2025 ABS release, alongside 18 validated new addresses recorded since the Census date. With 2,803 persons per square kilometer, the suburb places within the upper quartile of population density nationally across locations evaluated by AreaSearch.

Furthermore, the suburb's 5.5% expansion rate from the 2021 census outperformed both the SA3 area (3.2%) and the wider SA4 region, positioning it at the forefront of local growth. Net overseas migration served as the primary catalyst for these demographic gains, generating roughly 63.0% of the recent population additions. SA2 demographic projections released in 2024 (using 2022 as a baseline) by Geoscience Australia and the ABS are incorporated by AreaSearch, with NSW State Government SA2 figures from 2022 (using a 2021 baseline) applied where coverage gaps exist. In projecting outcomes from 2032 to 2041 across all territories, age-specific growth trajectories from these datasets are implemented. Looking toward future horizons, the suburb of Oyster Bay is anticipated to track slightly under the national statistical area median, gaining an estimated 264 persons by 2041 under aggregated SA2 models—an overall rise of 4.3% spanning the 16 years.

Residential SupplyHousing Development & Building Approvals in Oyster Bay

Table Chart PROFILE FAQ

90 new dwellings have been approved in Oyster Bay over the past five years, an average of 18 a year. That is 2.8 approvals per 1,000 residents. Approvals are currently running at an annualised 11, well below that longer-run average. Figures come from ABS building approvals aggregated to this Suburb (SAL) boundary and are updated monthly as the ABS releases them.

Detail

An evaluation of ABS building approval allocations by AreaSearch shows that the suburb records approximately 18 approved residential dwellings each year, totaling roughly 90 approved homes across the past 5 financial years (between FY-21 and FY-25), with 11 approvals lodged to date in FY-25. The ratio of 1.9 new residents annually per built home over the past 5 financial years (between FY-21 and FY-25) indicates balanced underlying supply and demand dynamics, though a recent shift to 4.3 people per dwelling across the past 2 financial years points toward rising demand pressures and a narrowing supply pipeline.

Residential initiatives carry an average construction value of $723,000, underscoring an emphasis on higher-end builds. Meanwhile, commercial approvals registered at $7.3 million during this financial year reflect the area's established residential profile. Per capita residential development in the locality closely aligns with Greater Sydney averages, reinforcing local market equilibrium in step with broader metropolitan trends. Construction volumes sit below national benchmarks, signaling established urban density and potential physical development limits. Contemporary building activity is divided between 53.0% standalone houses and 47.0% medium to high-density formats, incorporating townhouses and multi-unit developments to provide diverse housing options ranging from family properties to lower-maintenance spaces. This contrasts with the prevailing built environment (where houses make up 80.0%), highlighting site scarcity and changing demographic needs for varied residential formats. Recording approximately 599 people per dwelling approval, the market exhibits mature characteristics. Projections indicate that the area will absorb an additional 258 residents by 2041 relative to the most recent quarterly estimate from AreaSearch. Current building volumes appear well-positioned to accommodate this incoming demand, fostering favorable purchasing conditions and potentially paving the way for demographic gains ahead of current projections.

Jobs & IndustryEmployment Trends in Oyster Bay

Table Chart PROFILE FAQ

3,312 residents of Oyster Bay are employed, from a labour force of 3,381. Unemployment sits at 2.0%, with participation at 71.1%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.8% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 4,613, about 77% of the resident population, so more people leave the area for work than travel in. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.

Detail

Local workforce figures compiled by AreaSearch across statistical boundaries highlight a highly educated population, significant participation in professional service roles, and an unemployment rate of just 2.0%, reflecting stable year-on-year job conditions. By March 2026, 3,312 residents were actively employed, while the local jobless rate sat 2.1% lower than Greater Sydney's 4.1%. Labor force participation stood at 71.1%, against 68.9% for Greater Sydney. Additionally, 53.1% of working residents reported working from home during the Census, though pandemic-related lockdown measures during that period are a relevant factor. The primary sectors engaging local workers comprise professional & technical services, construction, along with education & training.

In particular, construction demonstrates heavy local weighting, employing residents at 1.4 times the regional proportion. Conversely, health care & social assistance accounts for only 11.3% of the local workforce compared to 14.1% regionally across Greater Sydney. Given the discrepancy between resident worker counts and local jobs noted in the Census, this predominantly residential locality generates relatively few jobs within its own boundaries. Through synthesis of ABS and SALM data over the 12 months leading to March 2026, local employment expanded by 0.1% alongside a 0.3% rise in the labour pool, resulting in a 0.2 percentage point uptick in the unemployment rate. Concurrently, Greater Sydney saw both employment and the labour force expand by 1.9%, accompanied by a slight decrease in joblessness. National employment outlooks released by Jobs and Skills Australia in Mar-26 provide additional context regarding future hiring trajectories. Nationally, job numbers are projected to grow by 6.6% across five years and 13.7% over ten years, with performance varying widely across industries. Applying these sector-level expectations to the local workforce composition projects an employment rise of 6.8% over five years and 13.7% over ten years (representing an unadjusted weighted extrapolation for illustrative purposes that excludes local population forecasts).

How the numbers are built

Population

The Census provides the small-area baseline, aggregated from mesh blocks to this boundary. It is then re-based to the ABS Estimated Resident Population (June 2025 release), and new dwellings built since Census night are counted from address data — 18 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (5,689 at the 2021 Census → 6,000 now). Annual growth rates are compound (CAGR), not simple averages.

Age profile

Cohort shares are not raw Census counts. Every cohort is held as a pair — the Census baseline and a current estimate — and the split is re-based using ERP and state population projections, current to Aug 2026. Median age is the Census median plus modelled change since. Charts that show both are labelled "2021 Census vs Current Estimate".

Property sales

Sourced from the state valuation authority's sales register — current, not Census, and refreshed weekly. Medians are calculated from settled transactions in the period shown; periods with very low transaction counts are flagged or suppressed, because a handful of sales can move a median substantially.

Rents

Derived from state rental bond lodgement data, by dwelling type and bedroom count. Bonds are lodged at the start of a new tenancy, so this reflects new lettings, not the whole rented stock.

Development & infrastructure

Building approvals come from current ABS releases; development applications are collected from council and state planning portals; the infrastructure pipeline is compiled from Infrastructure Australia and local government sources. Applications are matched to this boundary by address or coordinates, so very recent lodgements may not yet appear.

Employment & income

Industry and occupation structure comes from the Census, but the headline labour-market indicators do not. Unemployment and labour force are derived from ABS Small Area Labour Markets (quarterly). The employment outlook applies Department of Employment forecasts for all 19 industry divisions to this area's own industry mix (the agency is now Jobs and Skills Australia), as does the Internet Vacancy Index used for job demand. Because it is weighted on industry composition alone, that outlook carries no allowance for local population growth — in fast-growing areas the real rise in local jobs will typically be higher. Income combines Census household income with ATO taxable-income statistics for FY 2023, indexed forward using the Wage Price Index.

Education, transport & amenities

School enrolments, ICSEA and performance come from ACARA's current release, not the Census. Public transport stops and service frequency are derived from GTFS timetable feeds published by state transport departments. Services and amenities are proximity and count scores built from provider directories, refreshed on their own cycle. The Census contributes only the travel-to-work and qualification measures.

Rankings and benchmarks. Where we rank this area, the comparison set is every area of the same boundary type — suburbs against suburbs, SA2s against SA2s. Benchmarks compare this area against its greater capital city region and the national figure for the same measure and period.

Limits worth knowing. Small areas carry larger error margins, and the ABS introduces small random adjustments to Census counts to protect confidentiality — so totals may not sum exactly. Estimates re-based from regional data describe the area's expected trajectory, not a direct count of it. Figures are indicative for research and are not financial, planning or valuation advice.

Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (SAL13123). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.

Common questions about this page

How do Oyster Bay suburb boundaries differ from Statistical Areas?
This page uses Suburbs and Localities (SAL) boundaries (suburb-style geography). SAL represents commonly-known suburb names used in addresses, while Statistical Areas (SA2) are designed for census/statistical reporting. Even when sharing the same name, SAL and SA2 boundaries often cover different geographic areas with different populations.
Where does the data on this Oyster Bay page come from?
AreaSearch compiles this page from official and industry sources — including ABS, Geoscience Australia, Valuer General, Provider directories, DEWR, JSA, State Transport Departments and ACARA — then aggregates them to the boundary shown and calculates the rankings, growth rates and benchmarks itself. Property sales come from the state valuation authority, rents from state rental bond lodgements, development applications from council and state planning portals, school data from ACARA, and public transport from state transport departments.
Is the Oyster Bay data on this page just from the 2021 Census?
No. Most of this page is maintained well beyond the Census. Sourced entirely from current releases: development & approvals (Aug 2026), property sales & rents (Aug 2026), infrastructure projects (May 2026) and services & amenities (Jul 2026). Built on a Census baseline but carrying newer measures on top: population (to Aug 2026), age profile (to Aug 2026), employment (to Mar 2026), income (to FY 2023), education (to Aug 2026), transport (to Jul 2026) and health (to 2024). Population and age cohorts in particular are re-based to the latest ABS Estimated Resident Population rather than left at 2021 counts. Only housing, households and cultural diversity remain wholly Census-based, because no more current small-area dataset exists for those measures.
