Seventeen Mile Rocks

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

As of November 2025, the estimated population of Seventeen Mile Rocks is around 2,937. This reflects an increase from the 2021 Census figure of 2,699 people, marking an 8.8% growth in population. The latest estimate by AreaSearch, based on examination of the ABS ERP data release from June 2024 and additional validated new addresses since the Census date, puts the resident population at 2,947. This results in a density ratio of 1,391 persons per square kilometer, higher than the average seen across national locations assessed by AreaSearch. The suburb's growth rate outperformed both its SA3 area (2.9%) and SA4 region since the 2021 Census. Overseas migration contributed approximately 54.0% of overall population gains in recent periods.

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, Queensland State Government's SA2 area projections from 2023, based on 2021 data, are used. However, these state projections do not provide age category splits, so AreaSearch applies proportional growth weightings in line with the ABS Greater Capital Region projections released in 2023, based on 2022 data. According to projected demographic shifts, Seventeen Mile Rocks' population is expected to decline by 317 persons by 2041. However, specific age cohorts are anticipated to grow, notably the 75 to 84 age group, which is projected to increase by 74 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 shows Seventeen Mile Rocks has received around 1 residential property approval per year over the past 5 financial years, totalling approximately 8 homes. As of FY26, 2 approvals have 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.

In FY26, $41,000 in commercial approvals have been registered, suggesting minimal commercial development activity. Compared to Greater Brisbane, Seventeen Mile Rocks has around two-thirds the rate of new dwelling approvals per person and ranks among the 11th percentile nationally, implying limited buyer options while strengthening demand for established dwellings. However, building activity has accelerated in recent years. All new construction consists of detached houses, sustaining the area's suburban identity with a concentration of family homes suited to buyers seeking space.

With approximately 1472 people per dwelling approval, Seventeen Mile Rocks reflects a highly mature market. Given population is expected to remain stable or decline, reduced pressure on housing may create opportunities for buyers in the future.

In comparison, Greater Brisbane saw employment growth of 4.4% and labour force growth of 4.0%, with unemployment falling by 0.4 percentage points. Jobs and Skills Australia's national employment forecasts from Sep-22 project overall employment growth of 6.6% over five years and 13.7% over ten years, but growth rates vary significantly between sectors. Applying these projections to Seventeen Mile Rocks' employment mix suggests local employment should increase by 7.0% over five years and 14.4% over ten years, although these are simple extrapolations for illustrative purposes and do not consider localised population projections.
