AreaSearch adopts 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 for years post-2032, Queensland State Government's SA2 area projections, released in 2023 and based on 2021 data, are adopted. It should be noted that these state projections do not provide age category splits; hence, where utilised, AreaSearch applies proportional growth weightings in line with the ABS Greater Capital Region projections (released in 2023, based on 2022 data) for each age cohort. As we examine future population trends, projections indicate a decline in overall population, with the area's population expected to reduce by 100 persons by 2041 according to this methodology. However, growth across specific age cohorts is anticipated, led by the 85 and over age group, which is projected to grow by 525 people.

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

Seventeen Mile Rocks - Sinnamon Park has averaged around 16 new dwelling approvals annually, totalling 82 homes over the past 5 financial years. So far in FY-26, 7 approvals have been recorded. Given population has fallen over the past period, housing supply has remained adequate relative to demand, creating a well-balanced market with good buyer choice, while new properties are constructed at an average value of $476,000, revealing that developers are targeting the premium market segment with higher-end properties. Additionally, $16.8 million in commercial approvals have been registered this financial year, indicating steady commercial investment activity.

When measured against Greater Brisbane, Seventeen Mile Rocks - Sinnamon Park has 82.0% more construction activity (per person), creating greater choice for buyers, though building activity has slowed in recent years. This level is similarly under the national average, indicating the area's established nature and suggesting potential planning limitations. New development consists of 29.0% detached houses and 71.0% attached dwellings. This trend toward denser development provides accessible entry options and appeals to downsizers, investors, and entry-level buyers. This shows a considerable change from the current housing mix (currently 86.0% houses), reflecting reduced availability of development sites and addressing shifting lifestyle demands and affordability requirements. With around 1981 people per dwelling approval, Seventeen Mile Rocks - Sinnamon Park reflects a highly mature market.

With population expected to remain stable or decline, Seventeen Mile Rocks - Sinnamon Park should see reduced pressure on housing, potentially creating opportunities for buyers.
