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.

DemographicsPopulation Growth in Tiwi

Table Chart PROFILE FAQ

Tiwi has an estimated 2,641 residents, up from 2,511 at the 2021 Census — a change of 130 people, or 5.2%. Overseas migration accounts for 100.0% of that increase. That puts 847 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 demographic findings from AreaSearch, the resident count of Tiwi stands at approximately 2,641 as of Aug 2026. This represents an addition of 130 people (5.2%) compared to the 2,511 people recorded in the 2021 Census. This net movement combines the June 2025 ABS estimated resident population figure of 2,641 with ongoing post-Census address validation. With 846 persons per square kilometer, local density closely tracks the broader benchmarks across AreaSearch study locations. Inward international migration served as the primary catalyst for local demographic expansion, functioning as virtually the sole contributor to recent population increases.

Population projections utilized by AreaSearch incorporate the 2024 ABS/Geoscience Australia dataset using 2022 as its baseline. For locations outside this scope and for modeling demographic changes beyond 2032, cohort-based growth rates from the ABS Greater Capital Region projections (issued in 2023 from 2022 benchmarks) are applied. Looking ahead, local demographic expansion is expected to outpace the national median across statistical areas, expanding by 365 persons through to 2041 relative to latest annual ERP figures, translating to an overall expansion of 13.8% across the 16 years.

Residential SupplyHousing Development & Building Approvals in Tiwi

Table Chart PROFILE FAQ

Detail

Residential building approvals across Tiwi have tracked at roughly 2 dwellings per annum, amounting to 10 homes over the preceding 5 financial years. Given recent population contractions, this volume of building activity provides balanced supply conditions for prospective purchasers, with newly approved homes carrying an average construction value of $441,000. In addition, $17.5 million in commercial building permits was recorded during the current financial year, highlighting a moderate pace of non-residential construction. Residential construction in Tiwi is substantially subdued when contrasted with Greater Darwin, sitting 64.0% below the regional per capita benchmark.

Such restricted pipeline delivery typically underpins demand and pricing dynamics for established properties. This subdued level also trails national trends, underscoring local market maturity alongside possible physical or planning constraints. Furthermore, recent development has focused exclusively on freestanding dwellings, reinforcing the low-density neighborhood character favored by buyers seeking separate allotment living. This continuous delivery of detached residences exceeds the baseline distribution recorded at the Census (74.0%), confirming enduring demand for traditional family accommodation amidst broader urban consolidation. Projections indicate that Tiwi will add 365 residents out to 2041 according to recent quarterly estimates from AreaSearch. Should building output persist at existing modest volumes, residential stock may lag demographic requirements, potentially intensifying market competition and placing upward pressure on property values.

Jobs & IndustryEmployment Trends in Tiwi

Table Chart PROFILE FAQ

1,353 residents of Tiwi are employed, from a labour force of 1,397. Unemployment sits at 3.1%, with participation at 64.0%. Weighted for its industry mix, the area's sectors are forecast to grow about 7.3% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 4,690, about 178% of the resident population, so the area draws in more workers than it sends out. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.

Detail

The Tiwi workforce is characterized by high educational attainment and strong representation in essential service industries. The area maintains a low unemployment rate of 3.1% alongside an estimated annual employment growth of 0.5%. According to data from March 2026, 1,353 residents are currently employed. This local unemployment rate sits 0.3% lower than the 3.5% recorded for Greater Darwin. However, workforce participation rates fall considerably behind the regional standard, standing at 64.0% versus 72.9% in Greater Darwin. Census data indicates that only 4.6% of residents engage in remote work, a figure that likely reflects the lingering effects of Covid-19 lockdown measures.

Locally resident workers are primarily engaged in health care & social assistance, public administration & safety, as well as education & training. Specialisation is exceptionally elevated within health care & social assistance, capturing an employment proportion 1.9 times the wider regional baseline. In contrast, public administration & safety captures 15.6% of local workers compared to 19.5% across the broader region. With 2.1 jobs located within the boundary for every resident worker at the Census, the precinct serves as a major employment destination, drawing a net commuter inflow from adjoining suburbs. An examination of combined SALM and ABS figures by AreaSearch reveals that during the 12 months to March 2026, resident employment advanced by 0.5% while the local workforce expanded by 0.7%, resulting in a 0.2 percentage points lift in the unemployment rate. Across Greater Darwin, employment grew by 0.4%, the labour supply expanded by 0.8%, and joblessness rose by 0.3 percentage points. Medium to long-term workplace requirements can be evaluated through national employment outlooks published by Jobs and Skills Australia as of Mar-26. These five-year and ten-year sectoral trajectories have been weighted against local occupational distributions. Against anticipated national workforce expansions of 6.6% across five years and 13.7% across ten years, applying sectoral projections to Tiwi's specific industry composition indicates local employment expansion of 7.3% over five years and 15.1% over ten years (representing an illustrative weighted modeling exercise without direct local population adjustments).

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. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (2,511 at the 2021 Census → 2,641 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 (701021027). 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 Tiwi 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 Tiwi 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 Tiwi 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 (Aug 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.
