Mount Crosby

Mount Crosby is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

Based on analysis of ABS population updates for the broader area, as of Nov 2025, Mount Crosby's estimated population is around 1,973. This reflects an increase of 113 people since the 2021 Census, which reported a population of 1,860. The change is inferred from AreaSearch's estimate of 1,966 residents following examination of ABS's latest ERP data release (June 2024) and additional validation of 26 new addresses since the Census date. This level of population equates to a density ratio of 131 persons per square kilometer. Population growth was primarily driven by overseas migration contributing approximately 61.0% 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 are adopted, released in 2023 based on 2021 data. Population projections indicate a decline of 14 persons by 2041 according to this methodology. However, growth across specific age cohorts is anticipated, led by the 85 and over age group, projected to increase by 95 people.

AreaSearch assessment of residential development drivers sees a low level of activity in Mount Crosby, placing the area among the bottom 25% of areas assessed nationally

AreaSearch analysis of ABS building approval numbers in Mount Crosby shows an average of approximately 5 new dwelling approvals annually. Between financial years FY-21 and FY-25, around 25 homes were approved, with a further 3 approved so far in FY-26.

The average number of people moving to the area per year for each dwelling built over these five years was 0.9. This indicates that new supply is keeping pace with or exceeding demand, providing ample buyer choice and creating capacity for population growth beyond current forecasts. The average construction value of new properties was $438,000, suggesting a focus on the premium market with high-end developments. Comparatively, Mount Crosby shows substantially reduced construction compared to Greater Brisbane, at 78.0% below the regional average per person. This limited new supply generally supports stronger demand and values for established homes, which is also under the national average.

This suggests the area's established nature and potential planning limitations. Recent development in the area has been entirely comprised of detached houses, maintaining Mount Crosby's traditional low density character with a focus on family homes appealing to those seeking space. The estimated count of 426 people per dwelling approval reflects its quiet, low activity development environment. With population projections showing stability or decline, Mount Crosby should see reduced housing demand pressures, benefiting potential buyers.
