Of the 32 dwellings approved in the latest reporting year, 31% were detached houses and the rest townhouses or apartments.

Detail

Based on AreaSearch reviews of ABS residential building approvals distributed from statistical geographic units, Gymea Bay has averaged approximately 30 residential development approvals yearly, sum total of 151 properties over the last 5 financial years. In the current period of FY-26, 18 approvals have been documented. With a ratio of 1.3 individuals moving to the area per completed dwelling over the past 5 financial years (from FY-21 to FY-25), local housing demand matches supply closely, supporting balanced market dynamics. New properties are constructed with a mean valuation of $522,000, indicating that builders are targeting the higher-end market segment with premium projects.

Furthermore, commercial building approvals have reached $2.3 million this financial year, highlighting that the neighborhood remains predominantly residential.

Current residential construction consists of 31.0% standalone houses and 69.0% medium-to-high density options like apartments and townhouses. This preference for denser housing forms offers more accessible entry points for buyers, attracting individuals looking to downsize, real estate investors, and first-home buyers. This pattern marks a distinct shift from the existing housing stock (which stands at 90.0% standalone houses), indicating a scarcity of raw land and responding to evolving lifestyle preferences and budget constraints. With a ratio of roughly 252 residents per approved dwelling, Gymea Bay exhibits standard low-density characteristics. Long-term projections indicate that the suburb of Gymea Bay is on track to add 437 new residents by 2041, measured from the latest quarterly figures compiled by AreaSearch.

Jobs & IndustryEmployment Trends in Gymea Bay

Table Chart PROFILE FAQ

4,124 residents of Gymea Bay are employed, from a labour force of 4,203. Unemployment sits at 1.9%, with participation at 72.6%. 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 5,529, about 76% 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

The local labor pool is characterized by high levels of education, with a strong presence in professional fields, a jobless rate of a mere 1.9%, and steady workforce numbers over the past year, according to AreaSearch aggregations of regional data. By March 2026, there are 4,124 employed locals, while the local unemployment rate sits 2.2% lower than the Greater Sydney benchmark of 4.1%. Labor force participation is healthy, standing at 72.6% compared to the Greater Sydney rate of 69.1%. Census responses indicate that a significant 48.6% of the workforce operated from home, though this figure may have been influenced by pandemic-related movement restrictions.

The principal sectors employing residents are building and construction, healthcare and social assistance, along with professional and technical services. There is a particularly high concentration of workers in the construction sector, running at 1.6 times the metro-wide average. Conversely, healthcare and social assistance plays a smaller role locally, employing 11.9% of working residents compared to 14.1% across the wider region. Comparing the number of local jobs to the size of the resident workforce suggests that this mainly residential suburb offers few employment positions within its own boundaries. AreaSearch evaluated SALM and ABS data that were combined from larger statistical regions for the period ending March 2026. Employment levels remained unchanged at 0.0% while the labour force expanded by 0.4%, which led to an increase in unemployment of 0.3 percentage points. This outcome differs from the experience in Greater Sydney, where employment grew by 1.9%, the labour force also grew by 1.9%, and unemployment decreased slightly. Jobs and Skills Australia released national employment forecasts in May-25 that can help understand future demand in Gymea Bay. These forecasts span five and ten year intervals and have been aligned with the local employment structure to project growth trajectories. National employment is expected to rise by 6.6% over five years and by 13.7% over ten years, though expansion varies considerably across different industry sectors. When these sectoral growth rates are applied to Gymea Bay's current employment composition, local employment is projected to grow by 6.8% over five years and by 13.7% over ten years. This calculation uses a basic weighting method for demonstration and does not incorporate 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 — 45 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (6,983 at the 2021 Census → 7,241 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 May 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 (SAL11834). 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 Gymea 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 Gymea 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 Gymea 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 (Jun 2026), property sales & rents (Aug 2026), infrastructure projects (Jun 2026) and services & amenities (Jul 2026). Built on a Census baseline but carrying newer measures on top: population (to May 2026), age profile (to May 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.
