Sinagra

Sinagra lies within the top quartile of areas nationally for population growth performance according to AreaSearch analysis of recent, and medium to long-term trends

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch since the Census, Sinagra's population is estimated at around 3,474 as of Nov 2025. This reflects an increase of 374 people (12.1%) since the 2021 Census, which reported a population of 3,100 people. The change is inferred from the resident population of 3,360 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 686 validated new addresses since the Census date. This level of population equates to a density ratio of 1,940 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Sinagra's 12.1% growth since the 2021 census exceeded the national average (9.7%), marking it as a growth leader in the region. Population growth for the area was primarily driven by overseas migration that contributed approximately 68.0% of overall population gains during recent periods, although all drivers including natural growth and interstate migration were positive factors.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, and to estimate growth across all areas in the years post-2032, AreaSearch is utilising the growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections released in 2023 based on 2022 data. Considering the projected demographic shifts, a population increase just below the median of statistical areas analysed by AreaSearch is expected, with the Sinagra statistical area (Lv2) expected to expand by 306 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 6.1% in total over the 17 years.

AreaSearch assessment of residential development activity positions Sinagra among the top 25% of areas assessed nationwide

AreaSearch analysis of ABS building approval numbers for Sinagra shows approximately 77 new homes approved annually over the past five financial years from FY-21 to FY-25. This totals an estimated 387 homes. As of FY-26, 95 approvals have been recorded. The average increase in residents per year per dwelling constructed during this period is 0.6.

Commercial approvals registered in FY-26 amount to $1.1 million. Sinagra has 112.0% more building activity per person compared to Greater Perth, indicating strong developer confidence and greater buyer choice. Recent construction comprises 98.0% detached dwellings and 2.0% townhouses or apartments, maintaining the area's suburban character focused on family homes. Sinagra reflects a developing area with around 24 people per approval. According to AreaSearch's latest quarterly estimate, Sinagra is expected to grow by 211 residents by 2041.

Current development patterns suggest new housing supply should meet demand, offering good conditions for buyers and potentially facilitating population growth beyond current projections.

Professional & technical services employed only 5.8% of local workers, below Greater Perth's 8.2%.

The area appeared to offer limited employment opportunities locally, as indicated by the count of Census working population versus resident population. In the 12-month period ending September 2025, employment increased by 4.6%, while the labour force grew by 3.7%, causing the unemployment rate to fall by 0.9 percentage points. This contrasted with Greater Perth, where employment rose by 2.9%, the labour force grew by 3.0%, and unemployment rose marginally. State-level data as of 25-Nov-25 showed WA employment contracted by 0.27% (losing 5,520 jobs), with the state unemployment rate at 4.6%. National employment forecasts from May-25 indicated an expansion of 6.6% over five years and 13.7% over ten years. Applying these projections to Sinagra's employment mix suggested local employment should increase by 6.4% over five years and 13.3% over ten years, based on a simple weighting extrapolation for illustrative purposes.
