Density is about 21 people per 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

Based on analysis of ABS demographic updates for the surrounding region and subsequent addresses verified by AreaSearch since the Census, the resident population of the suburb of Jilliby is estimated to be approximately 1,749 as of May 2026. This represents a growth of 55 people (3.2%) compared to the 2021 Census, which counted 1,694 residents. This adjustment is calculated from the estimated resident count of 1,749, determined by AreaSearch using the latest ABS ERP release from June 2025 alongside two validated new addresses registered since the Census. Such a population size translates to a density of 20 persons per square kilometer, which ensures substantial space for each resident.

This 3.2% expansion since the census puts the area within 0.2 percentage points of the SA4 region (3.4%), showing comparable growth patterns. Net overseas migration was the primary driver, accounting for roughly 47.0% of the population increase in recent times, though all other indicators including natural increase and interstate relocations remained positive. ABS and Geoscience Australia projections released in 2024 with a 2022 baseline are utilised by AreaSearch for SA2 areas. For localities not covered by these datasets, NSW State Government projections from 2022 with a 2021 baseline are substituted. Projected growth rates by age bracket from these files are applied to all locations for the period 2032 to 2041. Looking at future demographic trends for the suburb of Jilliby, population growth is anticipated to be slightly below the national median, with projections for the aggregated SA2 area indicating an increase of 109 persons by 2041, representing a total expansion of 6.2% over the 16 years.

Table Chart PROFILE FAQ

Detail

According to AreaSearch's evaluation of building approvals from the ABS for this statistical division, the suburb of Jilliby has recorded a yearly average of approximately two new home approvals, representing a total of 10 residential approvals over the five financial years from FY-21 to FY-25, and none during FY-26. With an average of 5.2 individuals arriving in the area for every new dwelling constructed between FY-21 and FY-25, demand remains well ahead of supply, typically generating upward pressure on property prices and intensifying buyer competition. Newly constructed homes average an estimated value of $419,000, which is higher than the regional average and points to a focus on higher-quality builds.

Additionally, commercial building approvals have reached $3.6 million in the current financial year, representing a minor commercial development footprint. Building activity in the suburb of Jilliby is considerably quieter than in Greater Sydney, registering 73.0% below the metropolitan average per capita. Although construction activity has picked up in recent times, the restricted volume of new completions generally supports demand and values for established houses. This rate also sits below the national benchmark, reflecting the established character of the area and potentially indicating planning constraints. In addition, recent additions have consisted solely of detached dwellings, preserving the traditional low-density residential profile of the area and focusing on family-oriented properties. A ratio of 580 people for every approved dwelling highlights the quiet, low-scale nature of local construction. Demographic projections indicate that the suburb of Jilliby will add 109 new residents between the current quarterly estimate from AreaSearch and 2041. While construction activity is keeping reasonable pace with this projected expansion, buyers are likely to encounter heightened competition as the resident population grows.

Weighted for its industry mix, the area's sectors are forecast to grow about 6.1% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 1,369, about 78% 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.

According to AreaSearch's analysis of SALM and ABS statistics for the broader statistical area, local employment grew by 2.2% over the 12 months leading to March 2026, while the labour force expanded by 2.7%, resulting in a 0.5 percentage point increase in the unemployment rate. By contrast, Greater Sydney experienced employment and labour force growth of 1.9% and 1.9% respectively, alongside a minor drop in unemployment. National employment forecasts from Jobs and Skills Australia published in May-25 provide further context for potential local demand. These five and ten-year forecasts have been applied to the local workforce structure to estimate future trends. Nationally, employment is projected to grow by 6.6% over five years and 13.7% over ten years, with distinct variations between sectors. Applying these industry projections to the local workforce mix suggests that employment in the suburb of Jilliby will grow by 6.1% over five years and 12.8% over ten years, representing a basic weighting extrapolation for illustrative purposes that does not incorporate local population projections.

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 — 2 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (1,694 at the 2021 Census → 1,749 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 (SAL12036). 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 Jilliby 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 Jilliby 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 Jilliby 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 (Aug 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.
