Flagstone

Flagstone lies within the top 10% of areas nationally in terms of population growth performance according to AreaSearch analysis of short and medium-term trends

Based on analysis of ABS population updates for Flagstone's broader area, and new addresses validated by AreaSearch, the suburb's population is estimated at around 8,925 as of November 2025. This reflects an increase of 1,838 people (25.9%) since the 2021 Census, which reported a population of 7,087 people. The change is inferred from the resident population of 8,539 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 557 validated new addresses since the Census date. This level of population equates to a density ratio of 675 persons per square kilometer, providing significant space per person and potential room for further development. Flagstone's 25.9% growth since the 2021 census exceeded the national average (8.9%), along with the state, marking it as a growth leader in the region. Population growth for the suburb was primarily driven by interstate migration that contributed approximately 60.0% of overall population gains during recent periods, although all drivers including natural growth and overseas migration were positive factors.

AreaSearch is adopting 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 is applying proportional growth weightings in line with the ABS Greater Capital Region projections (released in 2023, based on 2022 data) for each age cohort. Moving forward with demographic trends, exceptional growth, placing it in the top 10 percent of national statistical areas, is predicted over the period with the suburb expected to increase by 6,864 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 64.7% in total over the 17 years.

AreaSearch assessment of residential development activity positions Flagstone among the top 25% of areas assessed nationwide
