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

As of Nov 2025, Mount Crosby's population is estimated at around 1,958, reflecting an increase of 98 people since the 2021 Census which reported a population of 1,860. This change was inferred from AreaSearch's estimate of 1,957 residents following examination of ABS ERP data release in June 2024 and validation of additional 26 new addresses since the Census date. The suburb's population density is approximately 130 persons per square kilometer. Recent population growth was primarily driven by overseas migration contributing around 61.0% of overall gains. AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022.

For areas not covered and years post-2032, Queensland State Government's SA2 area projections from 2023 based on 2021 data are used, applying proportional growth weightings for age cohorts where necessary. By 2041, the suburb's population is projected to decline by 16 persons overall, but specific age cohorts like those aged 85 and over are expected to grow, with an increase of 95 people anticipated in this cohort.

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 shows Mount Crosby averaged around 4 new dwelling approvals annually. Over the past 5 financial years (FY-21 to FY-25), approximately 24 homes were approved, with an additional 2 approved in FY-26 so far.

This averages out to about 1 person moving to the area per year for each dwelling built over those years. New supply has kept pace with or exceeded demand, providing ample buyer choice and capacity for population growth beyond current forecasts. The average construction value of new properties is $438,000, consistent with regional patterns. Compared to Greater Brisbane, Mount Crosby shows substantially reduced construction activity (79.0% below the regional average per person). This limited new supply generally supports stronger demand and values for established homes.

It is also under the national average, indicating the area's established nature and suggesting potential planning limitations. Recent development in Mount Crosby has been entirely comprised of detached houses, maintaining its traditional low density character with a focus on family homes appealing to those seeking space. The estimated population count per dwelling approval is 384 people, reflecting its quiet, low activity development environment. With population projections showing stability or decline, housing demand pressures are expected to remain reduced, benefiting potential buyers in the area.

Employment conditions in Mount Crosby rank among the top 10% of areas assessed nationally

Mount Crosby has an educated workforce with strong professional services representation. Its unemployment rate was 0.8% in June 2025, below Greater Brisbane's 4.1%.

Employment growth over the past year was estimated at 0.7%. Workforce participation is high at 73.2%, compared to Greater Brisbane's 64.5%. Dominant employment sectors include health care & social assistance, education & training, and professional & technical services. Education & training shows particularly strong specialization with an employment share of 1.4 times the regional level.

Conversely, transport, postal & warehousing has lower representation at 2.4% versus the regional average of 5.6%. Employment opportunities locally appear limited based on Census working population vs resident population comparison. Over a 12-month period ending June 2025, employment increased by 0.7%, labour force by 0.6%, leaving unemployment broadly flat. This contrasts with Greater Brisbane where employment grew by 4.4%, labour force expanded by 4.0%, and unemployment fell by 0.4 percentage points. Jobs and Skills Australia's national employment forecasts from Sep-22 project national employment growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Mount Crosby's employment mix suggests local employment should increase by 7.0% over five years and 14.3% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not account for localized population projections.
