Jobs & IndustryEmployment Trends in Silverdale (NSW)

Table Chart PROFILE FAQ

3,500 residents of Silverdale (NSW) are employed, from a labour force of 3,543. Unemployment sits at 1.2%, with participation at 77.2%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.0% nationally over five years. That reflects industry composition only and makes no allowance for local population growth, so in an area growing as fast as this one it understates the likely rise in local jobs. The working-day population is estimated at 4,826, about 79% 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 workforce shows a healthy mix of professional and trades occupations, with construction workers representing a notable portion of the labor market, and an unemployment rate of only 1.2% according to statistical area aggregations. As of March 2026, there are 3,500 employed residents. The local unemployment rate sits 2.9% below the Greater Sydney average of 4.1%, while workforce participation is exceptionally high at 77.2% compared to the metropolitan average of 69.1%. Census records show that 28.9% of the working population worked from home, though this figure was likely influenced by pandemic-era lockdowns.

Local residents are predominantly employed in the fields of building and construction, education and training, and healthcare and social assistance. The concentration of construction workers is particularly high, standing at 2.4 times the metropolitan average. Conversely, professional and technical services are underrepresented, accounting for only 4.3% of workers compared to 11.5% across the region. A comparison between the local working population and resident workers suggests a shortage of local jobs. An analysis of SALM and ABS data from the surrounding region indicates that over the 12-month period, the local labor force contracted by 2.1% and total employment fell by 2.3%, leading to a 0.2 percentage point rise in the unemployment rate. This trend diverged from Greater Sydney, where employment and labor force both expanded by 1.9%, and unemployment saw a minor decrease. National employment forecasts from Jobs and Skills Australia as of May-25 offer additional context for future local demand. These five and ten-year projections have been applied to the local workforce structure to model potential changes. Nationally, employment is expected to grow by 6.6% over five years and 13.7% over ten years, though individual sector growth rates vary. Applying these trends to the local industry mix yields an estimated local employment increase of 6.0% over five years and 12.4% over ten years, though this is a simple weighted projection and does not factor in local population growth.

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 — 227 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (4,543 at the 2021 Census → 6,112 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 (SAL13559). 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 Silverdale (NSW) 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 Silverdale (NSW) 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 Silverdale (NSW) 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 (May 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.
