DemographicsPopulation Growth in Tumbi Umbi

Table Chart PROFILE FAQ

Tumbi Umbi has an estimated 5,356 residents. That puts 409 residents on each 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

According to AreaSearch's evaluation of broader regional ABS demographic releases alongside post-Census validated address counts, the suburb of Tumbi Umbi records an estimated resident tally of roughly 5,356 as of Aug 2026. Relative to the 5,369 individuals counted during the 2021 Census, this indicates a small contraction of 13 people (0.2%). This figure is calculated from the resident benchmark of 5,354 generated by AreaSearch after reviewing the ABS June 2025 ERP update, combined with 7 validated new addresses established post-Census. At this population scale, population density stands at 408 persons per square kilometer, ensuring ample physical room per resident and capacity for prospective development.

In recent times, population additions have been sustained almost exclusively by overseas migration flows. For local SA2 districts, AreaSearch implements the ABS/Geoscience Australia demographic projections published in 2024 (using 2022 as the base year), while turning to NSW State Government SA2 modeling issued in 2022 (benchmarked to 2021) for locations not captured in the primary dataset. Age-specific growth trajectories derived from these models are similarly applied across all territories for the 2032 to 2041 period. Taking into account these shifting demographic patterns, the suburb of Tumbi Umbi is slated to record long-term population growth just under the national median, gaining an estimated 280 persons by 2041 across aggregated SA2 projections, representing a cumulative 16-year expansion of 5.2%.

Residential SupplyHousing Development & Building Approvals in Tumbi Umbi

Table Chart PROFILE FAQ

22 new dwellings have been approved in Tumbi Umbi over the past five years, an average of 4 a year. That is 0.9 approvals per 1,000 residents. Approvals are currently running at an annualised 2, well below 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

AreaSearch's evaluation of ABS residential construction approvals mapped across local statistical zones indicates that Tumbi Umbi has averaged approximately 4 dwelling approvals annually, accumulating roughly 22 residential approvals throughout the preceding 5 financial years. Within FY-25 to date, 2 building consents have been issued. Against a backdrop of recent population declines, residential building volumes have remained relatively sufficient for market entrants, with newly approved dwellings reflecting an average construction cost of $541,000. Furthermore, commercial building approvals have reached $2.9 million during this financial year, underscoring the predominantly residential orientation of the locality.

Recent residential construction has comprised entirely detached houses, reinforcing the low-density environment and catering to purchasers seeking generous space. House builders are currently delivering a greater proportion of standalone dwellings than the existing housing stock (81.0% at the Census) would suggest, highlighting persistent appetite for standard family residences. Meanwhile, an estimated ratio of 2676 people per approved dwelling illustrates the tranquil, measured pace of local building activity. Demographic projections suggest that Tumbi Umbi will add 278 residents leading up to 2041, measured against AreaSearch's latest quarterly calculations. Should building activity fail to accelerate from current levels, housing creation could trail demographic expansion, potentially intensifying purchaser demand and placing upward pressure on property values.

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 — 7 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (5,369 at the 2021 Census → 5,356 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.

Common questions about this page

How do Tumbi Umbi 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 Tumbi Umbi 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 Tumbi Umbi 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 (May 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.
