This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Sales Detail
Mount Crosby has an estimated 1,984 residents, up from 1,860 at the 2021 Census — a change of 124 people, or 6.7%. Growth has averaged 1.1% a year over five years. Overseas migration accounts for 61.0% of that increase. That puts 133 residents on each square kilometre. Population is estimated from ABS Estimated Resident Population releases and GNAF address data, re-based from the 2021 Census and updated annually.
Detail
According to evaluations of ABS demographic releases for the region and subsequent address validations conducted by AreaSearch, the suburb of Mount Crosby has an estimated residency of 1,984 as of May 2026. This indicates a rise of 124 individuals (6.7%) from the 2021 Census, which documented 1,860 residents. This shift is derived from the figure of 1,984, calculated by AreaSearch using the ABS June 2025 ERP data combined with 29 validated new addresses registered after the Census. Such population numbers translate to 132 persons per square kilometer, indicating low density and space for potential future construction.
The suburb of Mount Crosby's post-census growth of 6.7% lags the nationwide benchmark (9.3%) by 2.6 percentage points, showing solid growth characteristics. The main driver of population growth was immigration from overseas, which was responsible for roughly 61.0% of the overall gains in recent times. Projections from ABS and Geoscience Australia published in 2024 with a 2022 baseline are applied to each SA2 region. For locations lacking this data or projections extending past 2032, Queensland Government SA2 projections from 2023 using 2021 data are substituted. Since these state-level figures do not specify age cohorts, AreaSearch distributes growth using weightings from the 2023 ABS Greater Capital Region projections based on 2022 data. Anticipated demographic shifts suggest a minor contraction ahead, with the total population of the suburb of Mount Crosby projected to shrink by 10 persons by 2041. Conversely, expansion is expected in particular age groups, most notably those aged 85 and over, which is projected to grow by 102 people.
Frequently Asked Questions - Population
21 new dwellings have been approved in Mount Crosby over the past five years, an average of 4 a year. That is 2.2 approvals per 1,000 residents. Approvals are currently running at an annualised 6, running ahead of that longer-run average. Figures come from ABS building approvals aggregated to this Suburb (SAL) boundary and are updated monthly as the ABS releases them.
Detail
AreaSearch evaluations of ABS building approval records indicate that the suburb of Mount Crosby averages approximately 4 new residential approvals yearly, with a total of 21 homes approved during the 5 financial years from FY-21 to FY-25, and 6 approvals recorded during FY-26 so far. Because an average of 5.1 new residents arrived per completed home over the 5 financial years between FY-21 and FY-25, demand outpaces supply, which typically drives up pricing and intensifies buyer rivalry. Furthermore, new residential properties show an average construction value of $438,000, indicating that developers are focusing on higher-end upscale projects.
Residential building activity in the suburb of Mount Crosby is remarkably low compared to Greater Brisbane, tracking 81.0% below the regional per capita benchmark. This lack of new inventory generally supports values and demand for existing houses. Approval volumes also fall below national standards, reflecting the established status of the neighborhood and potential zoning limits. Recent approvals consist solely of free-standing houses, which maintains the low-density profile of the community and appeals to buyers looking for larger blocks. A ratio of 659 people per single dwelling approval highlights the quiet pace of local building activity. Given that demographic counts are projected to remain steady or contract, the suburb of Mount Crosby is likely to experience less pressure on residential housing, which could open up opportunities for purchasers.

1,293 residents of Mount Crosby are employed, from a labour force of 1,302. Unemployment sits at 0.7%, with participation at 80.9%. Weighted for its industry mix, the area's sectors are forecast to grow about 7.0% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 1,431, about 72% of the resident population, so more people leave the area for work than travel in. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.
Detail
Based on statistical compilations from AreaSearch, the suburb of Mount Crosby features a highly educated labor force with a strong concentration of professionals, a low unemployment rate of 0.7%, and an estimated job growth rate of 11.5% over the past year. In March 2026, employed residents numbered 1,293, while local unemployment sat 3.6% below the Greater Brisbane average of 4.3%. Labor force participation is exceptionally high at 80.9% compared to the Greater Brisbane average of 70.4%. Census records show that a high 26.9% of workers operated from home, though this figure reflects historical pandemic lockdown conditions.
The primary sectors employing local residents are health care & social assistance, education & training, and professional & technical services. Educational instruction and training shows a strong concentration, with local representation running at 1.4 times the regional standard. In contrast, transport, postal & warehousing is underrepresented, making up only 2.4% of local employment compared to the regional average of 5.6%. Comparing local worker tallies against resident counts suggests a scarcity of local employment opportunities. According to AreaSearch compilations of SALM and ABS statistics for the year ending March 2026, local employment grew by 11.5% while the labor force expanded by 11.1%, leading to a decrease of 0.3 percentage points in the unemployment rate. Over the same timeframe, Greater Brisbane recorded job growth of 3.2%, labor force growth of 3.4%, and a 0.1 percentage point rise in unemployment. National employment projections from Jobs and Skills Australia issued in May-25 offer additional perspective on prospective hiring trends. These five and ten-year forecasts have been applied to the local workforce structure to model future outcomes. While nationwide employment is projected to grow by 6.6% over five years and 13.7% over ten years, trends vary widely by sector. Applying these national industry rates directly to the local mix suggests job numbers could grow by 7.0% over five years and 14.3% over ten years, representing a simple weighted model that does not account for localized demographic changes.

How the numbers are built
Population
The Census provides the small-area baseline, aggregated from mesh blocks to this boundary. It is then re-based to the ABS Estimated Resident Population (June 2025 release), and new dwellings built since Census night are counted from address data — 29 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (1,860 at the 2021 Census → 1,984 now). Annual growth rates are compound (CAGR), not simple averages.
Age profile
Cohort shares are not raw Census counts. Every cohort is held as a pair — the Census baseline and a current estimate — and the split is re-based using ERP and state population projections, current to May 2026. Median age is the Census median plus modelled change since. Charts that show both are labelled "2021 Census vs Current Estimate".
Property sales
Sourced from the state valuation authority's sales register — current, not Census, and refreshed weekly. Medians are calculated from settled transactions in the period shown; periods with very low transaction counts are flagged or suppressed, because a handful of sales can move a median substantially.
Rents
Derived from state rental bond lodgement data, by dwelling type and bedroom count. Bonds are lodged at the start of a new tenancy, so this reflects new lettings, not the whole rented stock.
Development & infrastructure
Building approvals come from current ABS releases; development applications are collected from council and state planning portals; the infrastructure pipeline is compiled from Infrastructure Australia and local government sources. Applications are matched to this boundary by address or coordinates, so very recent lodgements may not yet appear.
Employment & income
Industry and occupation structure comes from the Census, but the headline labour-market indicators do not. Unemployment and labour force are derived from ABS Small Area Labour Markets (quarterly). The employment outlook applies Department of Employment forecasts for all 19 industry divisions to this area's own industry mix (the agency is now Jobs and Skills Australia), as does the Internet Vacancy Index used for job demand. Because it is weighted on industry composition alone, that outlook carries no allowance for local population growth — in fast-growing areas the real rise in local jobs will typically be higher. Income combines Census household income with ATO taxable-income statistics for FY 2023, indexed forward using the Wage Price Index.
Education, transport & amenities
School enrolments, ICSEA and performance come from ACARA's current release, not the Census. Public transport stops and service frequency are derived from GTFS timetable feeds published by state transport departments. Services and amenities are proximity and count scores built from provider directories, refreshed on their own cycle. The Census contributes only the travel-to-work and qualification measures.
Rankings and benchmarks. Where we rank this area, the comparison set is every area of the same boundary type — suburbs against suburbs, SA2s against SA2s. Benchmarks compare this area against its greater capital city region and the national figure for the same measure and period.
Limits worth knowing. Small areas carry larger error margins, and the ABS introduces small random adjustments to Census counts to protect confidentiality — so totals may not sum exactly. Estimates re-based from regional data describe the area's expected trajectory, not a direct count of it. Figures are indicative for research and are not financial, planning or valuation advice.
