Population
An assessment of population growth drivers in Streaky Bay reveals an overall ranking slightly below national averages considering recent, and medium term trends
As of Nov 2025, Streaky Bay's population is estimated at around 1,512 people. This reflects an increase of 76 people since the 2021 Census, which reported a population of 1,436 people. The change is inferred from AreaSearch's estimation of the resident population as 1,514 following examination of the latest ERP data release by the ABS (June 2024), along with an additional 61 validated new addresses since the Census date. This level of population equates to a density ratio of 3.0 persons per square kilometer. Over the past decade, Streaky Bay has shown resilient growth patterns with a compound annual growth rate of 0.6%, outpacing its SA3 area. Population growth for the suburb was primarily driven by natural growth contributing approximately 56% of overall population gains during recent periods, although all drivers including overseas migration and interstate migration were positive factors.
AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data and years post-2032, the SA State Government's Regional/LGA projections are adopted, based on 2021 data and adjusted employing a method of weighted aggregation of population growth from LGA to SA2 levels. Considering projected demographic shifts, Streaky Bay is expected to expand by 174 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 11.4% in total over the 17 years.

Development
AreaSearch analysis of residential development drivers sees Streaky Bay recording a relatively average level of approval activity when compared to local markets analysed countrywide
AreaSearch analysis shows Streaky Bay averaged around 9 new dwelling approvals annually. Between FY-21 and FY-25, approximately 46 homes were approved, with another 4 in FY-26 so far. This translates to an average of 1.4 new residents per year arriving per new home over the past five financial years.
The average construction value for these new homes is $395,000. In FY-26, there have been $3.6 million in commercial approvals, indicating limited commercial development focus compared to residential growth. Streaky Bay's building activity per person is 96.0% higher than the Rest of SA, offering more choice for buyers. All recent building activity consists of standalone homes, maintaining the area's traditional low density character with a focus on family homes.
With around 150 people per dwelling approval, Streaky Bay exhibits characteristics of a low-density area. Population forecasts indicate Streaky Bay will gain 173 residents by 2041, suggesting that current construction levels should adequately meet demand and create favourable conditions for buyers while potentially enabling growth beyond current forecasts.
