Sinnamon Park

Sinnamon Park is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

Based on ABS population updates and AreaSearch validation, the suburb of Sinnamon Park's estimated population was around 6,539 as of May 2026. This reflected a decrease of 51 people since the 2021 Census, which reported a population of 6,590. The change was inferred from AreaSearch's estimate of 6,539 residents following examination of ABS' latest ERP data release in June 2025 and validation of one new address since the Census date. This resulted in a population density ratio of 2,231 persons per square kilometer, above national averages assessed by AreaSearch. Overseas migration contributed approximately 54.0% of overall population gains during recent periods.

AreaSearch adopted ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022. For areas not covered and years post-2032, Queensland State Government's SA2 area projections released in 2023 based on 2021 data were used, applying proportional growth weightings from ABS Greater Capital Region projections released in 2023 based on 2022 data. Future demographic trends anticipate lower quartile growth of statistical areas nationally, with the suburb expected to expand by 41 persons to 2041, reflecting an increase of 0.6% over the 16 years.

The level of residential development activity in Sinnamon Park is very low in comparison to the average area assessed nationally by AreaSearch

AreaSearch analysis of ABS building approval numbers shows Sinnamon Park recorded around 13 residential properties granted approval annually. Over the past 5 financial years, from FY-21 to FY-25, approximately 66 homes were approved, with another 3 approved so far in FY-26. Despite a falling population during this period, development activity has been adequate relative to population changes, which could benefit buyers.

The average expected construction cost of new dwellings is $668,000, indicating developers target the premium market segment with higher-end properties. This year, $16.8 million in commercial development approvals have been recorded, suggesting steady commercial investment activity. Compared to Greater Brisbane, Sinnamon Park has 115.0% more new home approvals per person, offering buyers ample choice, although building activity has slowed recently. However, this level is below the national average, reflecting the area's maturity and potential planning constraints. New development consists of 20.0% detached dwellings and 80.0% attached dwellings, promoting higher-density living to create more affordable entry points for downsizers, investors, and first-home buyers. This shift marks a significant departure from existing housing patterns, which are currently 86.0% houses, suggesting diminishing developable land availability and responding to evolving lifestyle preferences and housing affordability needs. With around 6660 people per approval, Sinnamon Park is a mature, established area.

According to the latest AreaSearch quarterly estimate, Sinnamon Park is projected to add 41 residents by 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
