Residential SupplyHousing Development & Building Approvals in Tarrawanna

Table Chart PROFILE FAQ

25 new dwellings have been approved in Tarrawanna over the past five years, an average of 5 a year. That is 2.1 approvals per 1,000 residents. Approvals are currently running at an annualised 14, running ahead of that longer-run average. Figures come from ABS building approvals aggregated to this Suburb (SAL) boundary and are updated monthly as the ABS releases them.

Detail

According to AreaSearch evaluations of statistical area building approvals from the ABS, residential construction approvals in Tarrawanna have averaged around 5 new homes yearly, yielding roughly 25 homes across the past 5 financial years. During FY-25 to date, 14 approvals have been cataloged. Net movement into the area stood at an average of 1.8 people per year per constructed dwelling over the past 5 financial years (from FY-21 through FY-25), reflecting balanced supply and demand dynamics, whilst over the past 2 financial years this ratio softened to 1.2 people per dwelling to indicate even greater market equilibrium.

The mean construction value of newly approved residences stands at $631,000, illustrating an emphasis by builders on high-end, premium residential projects. Concurrently, $5.9 million in commercial development approvals was authorized during this financial year, reinforcing the predominantly residential profile of the locality. Construction rates in Tarrawanna sit substantially beneath regional figures, tracking 68.0% below regional average per person compared to Rest of NSW. Limited building volumes frequently bolster valuations and buyer interest for established stock, despite a recent uptick in building approvals. This pace also trails national standards, highlighting localized physical constraints alongside overall market maturity. Current development activity breaks down into 40.0% detached dwellings alongside 60.0% townhouses or apartments. This pivot toward medium and higher-density formats delivers entry-level price points well-suited to first-home purchasers, downsizers, and property investors. It represents a clear shift away from historical built forms (where houses represent 63.0%), mirroring changing lifestyle choices, affordability pressures, and reduced availability of greenfield land. Currently, the market reflects low density with approximately 248 people per dwelling approval. According to the latest quarterly modeling from AreaSearch, Tarrawanna is projected to gain 190 residents by 2041. While ongoing residential building is keeping suitable pace with expected demographic changes, prospective purchasers could encounter tighter competition as the population expands.

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 — 14 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (2,184 at the 2021 Census → 2,240 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 (SAL13784). 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 Tarrawanna 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 Tarrawanna 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 Tarrawanna 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 (Sep 2026), infrastructure projects (Apr 2026) and services & amenities (Jul 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 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.
