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 around Mount Crosby, and new addresses validated by AreaSearch since the Census, the suburb's population is estimated at around 1,973 as of Feb 2026. This reflects an increase of 113 people (6.1%) since the 2021 Census, which reported a population of 1,860 people. The change is inferred from the resident population of 1,966, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 27 validated new addresses since the Census date. This level of population equates to a density ratio of 131 persons per square kilometer, providing significant space per person and potential room for further development. Population growth for the area was primarily driven by overseas migration that contributed approximately 61.0% of overall population gains during recent periods.

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. Looking at population projections moving forward, over this period, projections indicate a decline in overall population, with the suburb's population expected to decline by 10 persons by 2041 according to this methodology. However, growth across specific age cohorts is anticipated, led by the 85 and over age group, which is projected to increase by 96 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

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Mount Crosby averaged around 5 new dwelling approvals annually. An estimated 25 homes were approved over the past five financial years, between FY-21 and FY-25, with an additional 3 approved so far in FY-26.

This averages out to approximately 0.9 people moving to the area per year for each dwelling built during these years. The new supply has been keeping pace with or exceeding demand, providing ample buyer choice and creating capacity for population growth beyond current forecasts. Developers have focused on the premium market, constructing new properties at an average value of $438,000. Compared to Greater Brisbane, Mount Crosby shows substantially reduced construction, 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, indicating the area's established nature and suggesting potential planning limitations.

Recent development 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 in the area 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.
