Detail

Demographic assessments by AreaSearch, drawing on regional ABS updates alongside newly confirmed post-censal addresses, indicate that the suburb of Jilliby has an estimated resident tally of 1,749 as of Aug 2026. This represents an addition of 55 people (3.2%) compared to the 1,694 people documented in the 2021 Census. Such movement is derived from the current ERP figures published by the ABS (June 2025) in conjunction with 3 validated new addresses registered following the census count. This resident count translates to a low-density living environment of 20 persons per square kilometer, ensuring considerable personal space.

The suburb of Jilliby expanded by 3.2% over this interval, trailing the broader SA4 region (3.4%) by merely 0.2 percentage points and highlighting robust underlying momentum. Inbound international arrivals served as the principal demographic catalyst, delivering roughly 47.0% of total population additions in recent times, though natural increases and interstate movements also contributed positively. Projections for the locality utilize ABS/Geoscience Australia SA2 modeling published in 2024 (anchored to 2022 baseline statistics), supplemented where necessary by NSW State Government SA2 forecasts from 2022 (benchmarked to 2021). Age-specific trajectory rates across these combined datasets are extended over the 2032 to 2041 period. Looking ahead, demographic modeling points to an expansion pace tracking slightly under the median benchmark of evaluated statistical territories, with the suburb of Jilliby anticipated to add 103 persons through to 2041 under aggregated SA2 projections, representing an overall rise of 5.9% across the 16 years.

Residential SupplyHousing Development & Building Approvals in Jilliby

Table Chart PROFILE FAQ

Detail

According to AreaSearch's evaluation of ABS residential construction permits within localized statistical divisions, planning authorities in Jilliby sanction approximately 2 dwellings each year. Over the preceding 5 financial years (between FY-21 and FY-25), an estimated total of 11 homes received permits, including 1 so far in FY-25. Over this five-year timeframe (between FY-21 and FY-25), inbound migration averaged 4.3 people annually for each newly constructed residence, creating a notable shortfall in dwelling additions that intensifies market competition and puts upward pressure on prices. Furthermore, incoming residential builds carry an average projected construction cost of $616,000—moderately higher than regional norms—pointing toward a standard of premium builds, while $3.6 million in non-residential development permits approved during this financial year highlights the locality's predominantly domestic setting.

Residential building volumes in Jilliby lag Greater Sydney substantially, falling 67.0% below regional average per person. A restricted pipeline of new construction routinely bolsters demand and supports valuation growth across existing stock. This construction rate also sits lower than national benchmarks, signaling an established urban footprint and potential planning bottlenecks. Furthermore, contemporary approvals consist exclusively of single-family residences, reinforcing the district's low-density profile where freestanding homes appeal strongly to purchasers prioritizing acreage and seclusion. The presence of roughly 1161 people per approved dwelling highlights an exceptionally quiet building market. Forward demographic estimates suggest that Jilliby will welcome 103 residents up to 2041, based on recent quarterly modeling from AreaSearch. Current residential construction is advancing at a rate that tracks projected demographic additions reasonably well, though purchasers may face intensifying competition as the local population increases.

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 — 3 validated new addresses here. The headline figure is therefore a current estimate for Aug 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 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 (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 (Aug 2026), property sales & rents (Oct 2026), infrastructure projects (Aug 2026) and services & amenities (Sep 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 Sep 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.
