Seventeen Mile Rocks

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

Based on ABS population updates and AreaSearch validation, the population of Seventeen Mile Rocks is estimated at around 2,901 as of Feb 2026. This reflects an increase of 202 people since the 2021 Census, which reported a population of 2,699. The change is inferred from AreaSearch's estimate of 2,896 residents following examination of ABS ERP data release in June 2024 and validation of 19 new addresses since the Census date. This level of population equates to a density ratio of 1,374 persons per square kilometer, above the average seen across national locations assessed by AreaSearch. Seventeen Mile Rocks' 7.5% growth exceeded the SA3 area's 3.1%, marking it as a growth leader in the region. Overseas migration contributed approximately 54.0% of overall population gains during recent periods.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered and years post-2032, Queensland State Government's SA2 area projections released in 2023 based on 2021 data are adopted. Projections indicate a decline in overall population by 380 persons by 2041. However, growth across specific age cohorts is anticipated, led by the 75 to 84 age group projected to expand by 66 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 indicates approximately one new home approved annually in Seventeen Mile Rocks. Over the past five financial years, from FY-21 to FY-25, around six homes were approved, with one more approved so far in FY-26.

This consistent supply has likely kept pace with demand despite a falling population, providing good buying options for consumers. The average expected construction cost value of new dwellings is $669,000, suggesting developers target the premium market with high-end developments. Comparatively, Seventeen Mile Rocks records significantly lower building activity than Greater Brisbane, at 55.0% below the regional per capita average. This limited supply typically supports stronger demand and values for established properties. However, development activity has increased recently.

Nationally, this activity is also below average, reflecting the area's maturity and possible planning constraints. Recent development in Seventeen Mile Rocks has been exclusively detached dwellings, maintaining its suburban identity with a focus on family homes suited to buyers seeking space. The area has approximately 982 people per dwelling approval, indicating an established market. With population projections showing stability or decline, housing demand pressures are expected to remain low, benefiting potential buyers.
