Sales Detail
Streaky Bay has an estimated 1,607 residents, up from 1,436 at the 2021 Census — a change of 171 people, or 11.9%. Growth has averaged 1.9% a year over five years, faster than 77% of areas nationally. 107 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 ABS population statistics analyzed for the wider region and address updates verified by AreaSearch since the Census, the suburb of Streaky Bay has an estimated population of 1,607 in May 2026. This represents a growth of 171 residents (11.9%) relative to the 2021 Census, which registered 1,436 individuals. The estimate is derived from a resident population of 1,605 calculated by AreaSearch using the ABS June 2025 ERP release alongside 107 validated new addresses registered since the Census. This population level corresponds to a density of 3.1 persons per square kilometer, indicating residents have plenty of space.
The 11.9% growth rate of the suburb of Streaky Bay since the 2021 census was higher than both the SA4 region (4.2%) and the SA3 area, positioning it as a leading growth zone. Natural increase was the main driver, accounting for roughly 56.00000000000001% of the total population growth in recent times, though interstate and overseas migration also made positive contributions. Projections from the ABS and Geoscience Australia released in 2024 with a 2022 baseline are utilized for each SA2 area. For SA2 areas without this coverage, or for periods after 2032, regional and LGA projections by age bracket published by the SA State Government in 2023 using 2021 data are applied, with adjustments made via a weighted aggregation of population growth from LGA to SA2 scale. Looking ahead, population growth is projected to be slightly below the median for regional Australian areas, with the suburb of Streaky Bay expected to add 194 residents by 2041 based on compiled SA2 projections, representing an overall expansion of 11.9% over the 16 years.
Frequently Asked Questions - Population
72 new dwellings have been approved in Streaky Bay over the past five years, an average of 14 a year. That places the area in the 61st percentile for residential development activity nationally, about 9 approvals per 1,000 residents a year. Approvals are currently running at an annualised 18, 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
An analysis of ABS building approvals by AreaSearch, distributed from statistical area data, shows Streaky Bay averaged approximately 14 new home approvals per year, with 72 residential builds approved over the last 5 financial years (between FY-21 and FY-25) and 17 approvals recorded so far in FY-26. With an average of 2 new residents arriving for every new dwelling built over the past 5 financial years (between FY-21 and FY-25), demand matches supply closely to support a balanced market, while new dwellings carry an average construction value of $395,000, showing that developers are focusing on upmarket, premium properties.
Furthermore, commercial development approvals total $1.8 million for this financial year, which points to limited commercial construction. In comparison to the Rest of SA, Streaky Bay exhibits 199.0% higher building approval numbers per resident, offering buyers a wider selection of properties. Recent approvals consist solely of standalone houses, preserving the local low density footprint and emphasizing spacious family living. With 96 people for every residential approval, Streaky Bay displays the traits of a growing community. Demographic projections indicate Streaky Bay will add 192 residents by 2041 compared to the most recent quarterly estimate from AreaSearch. The current rate of construction suggests housing supply will easily satisfy demand, creating positive conditions for buyers and potentially allowing growth to outpace current projections.

742 residents of Streaky Bay are employed, from a labour force of 833. Unemployment sits at 10.9%, with participation at 61.2%. 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 1,232, 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 has a balanced labor market split between white-collar and blue-collar roles across diverse industries, with an unemployment rate of 10.9% according to statistical area data compiled by AreaSearch. In March 2026, there were 742 residents in employment, while the unemployment rate was 5.5% higher than the Regional SA average of 5.5%, indicating a need for job growth. Labor force participation is typical at 61.2% compared to 58.4% in Regional SA. Census records show that only 10.6% of residents worked from home, although this was likely influenced by pandemic lockdowns.
The primary employment sectors for local workers are agriculture, forestry & fishing, retail trade, and health care & social assistance. The local economy shows a high concentration in retail trade, where the employment share is 1.4 times the regional average. In contrast, manufacturing is underrepresented at 2.1% compared to the regional average of 9.3%. The ratio of Census workers to local residents suggests that local job opportunities are somewhat restricted. According to an AreaSearch evaluation of SALM and ABS data compiled from wider statistical regions, the workforce shrank by 0.7% and job numbers fell by 7.1% in the year leading up to March 2026, which pushed the unemployment rate up by 6.2 percentage points. This trend differs from what occurred in Regional SA, where job numbers climbed by 1.2%, the workforce expanded by 2.6%, and the unemployment rate increased by 1.4 percentage points. To understand future job opportunities in Streaky Bay, one may examine Jobs and Skills Australia's national employment predictions released in May-25. These forecasts span five and ten year intervals and have been aligned with the local job profile to project growth trends. Although national employment is expected to grow by 6.6% over five years and 13.7% over ten years, expansion varies considerably across different industry groups. When these sector-specific forecasts are applied to Streaky Bay's current job composition, the area is projected to see a 5.5% rise in jobs over five years and an 11.9% increase over ten years, though this calculation is a basic weighting exercise for demonstration only and ignores local population changes.

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 — 107 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (1,436 at the 2021 Census → 1,607 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 May 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.
