This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Sales Detail
Sinagra has an estimated 3,795 residents, up from 3,100 at the 2021 Census — a change of 695 people, or 22.4%. Growth has averaged 4.1% a year over five years, faster than 91% of areas nationally. 1,109 new addresses have been validated here since Census night. Overseas migration accounts for 68.0% of that increase. That puts 2,120 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 evaluations combining broader statistical updates from the ABS with post-Census address validations, the suburb of Sinagra reached an estimated population of approximately 3,795 as of Aug 2026. Compared with the 3,100 residents recorded in the 2021 Census, this represents an addition of 695 people, or a 22.4% expansion. This estimate is based on the June 2025 ABS Estimated Resident Population release of 3,792 alongside 1,109 validated new addresses established post-Census. Consequently, population density stands at 2,120 persons per square kilometer, exceeding the typical benchmark across locations evaluated nationally by AreaSearch.
The suburb of Sinagra outpaced both its broader SA4 region and the national growth benchmark of 9.5% with its 22.4% rise since the 2021 census. While natural increase and interstate arrivals also contributed positively, overseas migration was the primary driver, accounting for roughly 68.0% of recent population additions. Demographic modeling applies ABS/Geoscience Australia SA2 projections published in 2024 using 2022 as a base, supplemented by ABS 2023 Greater Capital Region cohort trends based on 2022 data for subsequent years beyond 2032 and unmapped areas. Under this approach, the suburb of Sinagra is projected to experience a slight overall contraction of 8 persons by 2041. In contrast to this overall shift, selective demographic expansion is projected, particularly within the 45 to 54 cohort, which is expected to grow by 73 people. Further details are outlined in the age analysis.
Frequently Asked Questions - Population
573 new dwellings have been approved in Sinagra over the past five years, an average of 114 a year. That places the area in the 85th percentile for residential development activity nationally, about 30 approvals per 1,000 residents a year. Of the 159 dwellings approved in the latest reporting year, 98% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 268, 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
Analysis of ABS building approvals by AreaSearch indicates that residential construction in the suburb of Sinagra has averaged around 114 approved dwellings annually, yielding approximately 573 new homes over the preceding 5 financial years. Within FY-25 to date, 268 dwelling approvals have been registered. Construction activity has outpaced population demand, as only an average of 0.9 new residents per dwelling was added each year between FY-21 and FY-25, widening purchasing options and establishing capacity for higher growth while dwellings were built at an estimated average construction cost of $386,000. Non-residential development remained subdued, with commercial approvals recording $1.1 million during this financial year.
On a per-capita basis, building activity in the suburb of Sinagra surpasses Greater Perth by 282.0%, reflecting strong developer interest and expanding stock availability far above the national level. Detached houses constitute 98.0% of newly approved dwellings, with medium and high-density housing accounting for the remaining 2.0%, preserving the low-density suburban environment favored by families seeking spacious living. Approvals currently stand at approximately 14 people per dwelling approval, highlighting an expanding residential market. Given that the local population is projected to stabilize or contract, reduced demand on housing stock should improve purchasing conditions for prospective buyers.

2,054 residents of Sinagra are employed, from a labour force of 2,141. Unemployment sits at 4.1%, with participation at 74.2%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.4% nationally over five years. That reflects industry composition only and makes no allowance for local population growth, so in an area growing as fast as this one it understates the likely rise in local jobs. The working-day population is estimated at 3,146, about 83% of the resident population, so more people leave the area for work than travel in. 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 local labour force displays strong skills and solid representation in essential services, with an unemployment rate of 4.1% and yearly employment expansion estimated at 4.7% per AreaSearch statistical aggregations. As of March 2026, employed residents numbered 2,054, with unemployment tracking 0.1% below the 4.2% rate for Greater Perth, while participation stood at 74.2% against 69.9% regionally. Remote work was utilized by 8.0% of residents at the Census, though pandemic conditions may have shaped that figure. Leading fields of resident employment comprise health care & social assistance, construction, and retail trade.
Construction represents a major local specialization, employing a share of workers 1.4 times that of the broader region. Conversely, professional & technical roles account for only 5.8% of the local workforce, compared with 8.2% across Greater Perth. The discrepancy between working residents and local job counts indicates that local commercial employment opportunities remain relatively constrained within this residential setting. AreaSearch assessment of ABS and SALM figures shows that across the 12 months leading to March 2026, employment grew by 4.7% alongside a 4.8% increase in the labour force, resulting in a 0.1 percentage point rise in the local unemployment rate. Over the same timeframe, Greater Perth saw employment rise by 2.0% and the labour force grow by 2.5%, causing an increase of 0.4 percentage points in unemployment. Projections released in Mar-26 by Jobs and Skills Australia forecast overall national workforce growth of 6.6% across five years and 13.7% across ten years, with performance varying widely across industries. Applying these sectoral trajectories to the local occupational mix projects employment increases of 6.4% over five years and 13.3% over ten years, based on weighting extrapolation without adjusting for localized demographic shifts.

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 — 1,109 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (3,100 at the 2021 Census → 3,795 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.
