Statistical Area (SA2) Boundary Analysis

This analysis uses ABS Statistical Areas Level 2 (SA2) boundaries, which can materially differ from Suburbs and Localities (SAL) even when sharing similar names.

SA2 boundaries are defined by the Australian Bureau of Statistics and are designed to represent communities for statistical reporting (e.g., census and ERP).

Suburbs and Localities (SAL) represent commonly-used suburb/locality names (postal-style areas) and may use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Detail

According to research conducted by AreaSearch, the population of Jilliby - Yarramalong is estimated at approximately 3,627 as of May 2026. This represents a growth of 207 residents (6.1%) from the 3,420 citizens recorded during the 2021 Census. This adjustment is calculated utilizing the ABS estimated resident population of 3,627 as of June 2025 alongside 8 validated new addresses registered after the Census. Such population numbers translate to a density of 10.5 persons per square kilometer, indicating a spacious living environment. The area's 6.1% expansion rate since the 2021 census paced ahead of both the broader SA4 region (3.4%) and the SA3 territory, establishing it as a local growth frontrunner.

This population rise was chiefly powered by interstate migration, which accounted for roughly 44.3% of the total demographic gains, though all components including overseas arrivals and natural increase contributed positively. For each SA2 locality, AreaSearch employs projections from the ABS and Geoscience Australia published in 2024 using 2022 as the base year. Where these projections are unavailable, SA2 data from the NSW State Government released in 2022 using 2021 as the base year is applied. The age cohort growth velocities derived from these sources are likewise extended to cover the years 2032 to 2041. Based on these anticipated demographic trends, population growth is projected to track slightly below the national median for statistical areas, with a forecasted net addition of 221 individuals by 2041 relative to the most recent annual ERP statistics, representing an overall increase of 6.1% over the 16 years.

Table Chart PROFILE FAQ

42 new dwellings have been approved in Jilliby - Yarramalong over the past five years, an average of 8 a year. That is 2.4 approvals per 1,000 residents. Approvals are currently running at an annualised 3, well below that longer-run average. Figures come from ABS building approvals aggregated to this SA2 boundary and are updated monthly as the ABS releases them.

Detail

Jilliby - Yarramalong has recorded a yearly average of approximately 8 new home approvals, summing to 42 residences over the last 5 financial years. Thus far in FY-26, there have been 3 approvals documented. With an average of 4.3 new occupants per year for each built residence during the past 5 financial years (spanning FY-21 to FY-25), demand runs well ahead of new completions, a dynamic that typically spurs price appreciation and heightens buyer rivalry, with new buildings constructed at an average cost of $344,000. Additionally, commercial development approvals reached $6.2 million this financial year, underscoring the predominantly residential focus of the locality.

Jilliby - Yarramalong registers roughly 57% of the per capita construction volume observed in Greater Sydney, placing it in the 36th percentile of all examined locations nationwide, which translates to fewer purchasing options and bolsters demand for established properties. This below-average national standing points to a mature property market and potential planning hurdles. Furthermore, recent building starts consisted entirely of single-family detached houses, preserving the low-density character of the neighborhood and appealing to buyers seeking spacious environments. The ratio of 457 people for every single home approval emphasizes the quiet, low-intensity pace of local development. Projections for the future indicate that Jilliby - Yarramalong will gain 221 residents by 2041 (computed from the most recent quarterly estimates by AreaSearch). At current construction velocities, the incoming residential supply is expected to sufficiently satisfy demand, yielding favorable conditions for purchasers and potentially paving the way for expansion that outpaces current predictions.

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 — 8 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (3,420 at the 2021 Census → 3,627 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 (102021049). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.

Common questions about this page

Why can the Jilliby - Yarramalong SA2 boundary differ from the suburb boundary?
This page uses ABS Statistical Area Level 2 (SA2) boundaries for statistical reporting (e.g., census and ERP). SA2 areas can differ materially from Suburbs and Localities (SAL) boundaries, even when they share similar names, because they are defined for different purposes and often use different geographic boundaries.
Where does the data on this Jilliby - Yarramalong 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 - Yarramalong 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 (May 2026), property sales & rents (Aug 2026), infrastructure projects (Jul 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 Jul 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.
