Seventeen Mile Rocks

Seventeen Mile Rocks has shown very soft population growth performance across periods assessed by AreaSearch

Based on analysis of ABS population updates for the broader area, the estimated population of the suburb of Seventeen Mile Rocks as of May 2026 is around 3,108. This reflects an increase of 409 people since the 2021 Census, which reported a population of 2,699 people. The change is inferred from the resident population estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2025 and an additional 19 validated new addresses since the Census date. This level of population equates to a density ratio of 1,473 persons per square kilometer, above the average seen across national locations assessed by AreaSearch. The suburb's 15.2% growth since the 2021 census exceeded the SA3 area (3.0%) and the SA4 region, marking it as a growth leader in the region. Population growth for the suburb was primarily driven by overseas migration that contributed approximately 54.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered by this data and years post-2032, Queensland State Government's SA2 area projections are adopted, released in 2023 and based on 2021 data. It should be noted that these state projections do not provide age category splits; hence where utilised, AreaSearch is applying proportional growth weightings in line with the ABS Greater Capital Region projections for each age cohort, released in 2023 based on 2022 data. Considering the projected demographic shifts, projections indicate a decline in overall population by 270 persons by 2041 according to this methodology. However, growth across specific age cohorts is anticipated, led by the 75 to 84 age group, which is projected to increase by 70 people.

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

AreaSearch analysis of ABS building approval numbers for Seventeen Mile Rocks shows approximately one residential property granted approval per year over the past five financial years, totalling six homes. In FY26 so far, one approval has been recorded. The population decline during this period has maintained adequate housing supply relative to demand, resulting in a balanced market with good buyer choice.

New properties are constructed at an average value of $669,000, indicating developers target the premium market segment with higher-end properties. Compared to Greater Brisbane, Seventeen Mile Rocks has significantly lower building activity, 58.0% below the regional average per person, which typically strengthens demand and prices for existing properties. However, building activity has increased in recent years. The area's development is also below the national average, suggesting its established nature and potential planning limitations. Recent development consists entirely of standalone homes, preserving Seventeen Mile Rocks' traditional suburban character focused on family homes.

With approximately 966 people per dwelling approval, it demonstrates an established market. Given population projections indicate stability or decline, housing demand pressures in Seventeen Mile Rocks are expected to remain low, benefiting potential buyers.
