Sales Detail
Streaky Bay has an estimated 1,605 residents, up from 1,436 at the 2021 Census — a change of 169 people, or 11.8%. Growth has averaged 1.9% a year over five years, faster than 76% of areas nationally. 106 new addresses have been validated here since Census night. Natural increase accounts for 56.0% of that increase. Fewer than ten people live on each square kilometre, across a boundary that takes in surrounding rural land. 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 ABS demographic updates for the wider district with 106 validated new addresses since the Census, the suburb of Streaky Bay has an estimated resident population of around 1,605 as of Aug 2026. This represents an addition of 169 people, or an 11.8% expansion, over the 1,436 people documented in the 2021 Census, aligning closely with AreaSearch's June 2025 ERP assessment of 1,603 residents. The suburb of Streaky Bay offers substantial space per occupant, exhibiting a low density of 3.1 persons per square kilometer. With its 11.8% rate of gain outpacing both the SA3 area and the SA4 region (4.2%), the suburb of Streaky Bay stands out as a regional growth leader.
Natural increase served as the primary growth catalyst, generating roughly 56.00000000000001% of aggregate population additions in recent periods, complemented by positive inflows from both interstate migration and overseas migration. For individual SA2 locations, AreaSearch incorporates 2024 ABS/Geoscience Australia projections using 2022 as their starting baseline. In geographies lacking direct coverage or extending past 2032, state government 2023 age-specific Regional/LGA projections based on 2021 numbers are utilised through weighted aggregation from LGA to SA2 tiers. Under these demographic models, the suburb of Streaky Bay is projected to experience growth slightly beneath the national regional median, adding 189 persons by 2041 across aggregated SA2 data, corresponding to an overall 11.7% expansion over the 16 years.
Frequently Asked Questions - Population
84 new dwellings have been approved in Streaky Bay over the past five years, an average of 16 a year. That places the area in the 58th percentile for residential development activity nationally, about 10 approvals per 1,000 residents a year. Approvals are currently running at an annualised 19, broadly in line with 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 Streaky Bay averages approximately 16 residential approvals per year, accumulating an estimated 84 homes across the past 5 financial years. In FY-25 to date, 19 approvals have been issued. Across the past 5 financial years between FY-21 and FY-25, approximately 1.6 people arrived in the community annually for each newly constructed home, reflecting a balanced equilibrium between local construction and incoming demand that underpins market stability, alongside an average expected construction cost of $367,000 per dwelling. Non-residential building activity has been muted, with commercial approvals totaling $1.8 million during this financial year.
On a per-person basis, Streaky Bay outpaces the Rest of SA by 288.0% in construction activity, offering broad variety to prospective purchasers. This rate sits well above the Australian benchmark, demonstrating considerable appetite among developers. Recent approvals have comprised separate standalone houses exclusively, reinforcing the low-density fabric of the area and appealing to buyers seeking detached living and extra space. Accommodating about 99 people per dwelling approval, the locality displays typical traits of an expanding market. Long-term forecasts anticipate Streaky Bay gaining 187 residents by 2041, benchmarked from the most recent AreaSearch quarterly estimate. If ongoing construction patterns persist, the influx of new residential stock should easily accommodate demand, supporting favorable buyer conditions and potentially enabling demographic growth beyond projected levels.

737 residents of Streaky Bay are employed, from a labour force of 827. Unemployment sits at 10.9%, with participation at 60.9%. Weighted for its industry mix, the area's sectors are forecast to grow about 5.5% 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 1,233, about 77% 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
Streaky Bay maintains an employment base balanced across blue-collar and white-collar roles across multiple sectors, alongside an unemployment rate of 10.9% derived from AreaSearch statistical area datasets. As of March 2026, employed residents stand at 737, while joblessness sits 5.4% above the Regional SA benchmark of 5.5%, indicating capacity for economic strengthening. Participation in the labour force is typical at 60.9%, compared with 58.3% across Regional SA. Remote working was recorded at a modest 10.6% in Census returns, though this may have been influenced by Covid-19 restrictions. Local resident employment is largely clustered within retail trade, agriculture, forestry & fishing, and health care & social assistance.
The retail trade sector is exceptionally prominent, employing workers at 1.4 times the regional incidence. In contrast, manufacturing captures a smaller share of the workforce, accounting for 2.1% locally versus 9.3% across the wider region. Comparing the working-age population against resident counts suggests a relatively constrained volume of internal employment positions. Drawing on ABS and SALM figures aggregated by AreaSearch, the local labour force contracted by 0.8% over the 12-month period, while total employment fell by 7.1%, driving a 6.0 percentage points increase in the jobless rate. By comparison, Regional SA recorded increases of 1.2% in employment and 2.6% in the labour force, alongside a 1.4 percentage point rise in unemployment. Looking forward, national forecasts released in Mar-26 by Jobs and Skills Australia project employment growth of 6.6% over five years and 13.7% over ten years, though sector trajectory varies. Weighting these projections across Streaky Bay's specific industry distribution indicates potential local job gains of 5.5% over five years and 11.9% over ten years, noting this illustrative exercise applies simple sector weighting without incorporating local population projections.

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 — 106 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (1,436 at the 2021 Census → 1,605 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.
