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.

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 AreaSearch's evaluation of ABS regional demographic releases and newly verified addresses post-Census, the suburb of Mount Crosby reaches an estimated 1,984 residents as of Aug 2026. This marks an expansion of 124 people (6.7%) from the 1,860 people recorded in the 2021 Census. This adjustment stems from the resident baseline of 1,984 calculated via the ABS June 2025 ERP update alongside 29 validated new addresses logged following the Census. Consequently, population density stands at 132 persons per square kilometer, offering generous personal space and scope for future additions.
The suburb of Mount Crosby and its 6.7% post-Census increase trails the national benchmark (9.5%) by 2.8 percentage points, highlighting solid local growth dynamics. Inbound overseas migration served as the primary growth driver, accounting for roughly 61.0% of recent population additions. Projections for the suburb of Mount Crosby incorporate 2024 ABS/Geoscience Australia SA2 modeling using 2022 as a base, supplemented post-2032 or where unavailable by 2023 Queensland State Government SA2 series based on 2021 numbers. Because state series omit age breakdowns, proportional weightings from the 2023 ABS Greater Capital Region data (2022 base) are assigned across cohorts. Under this framework, future projections suggest a slight contraction, with the suburb of Mount Crosby expected to lose 27 persons by 2041. Conversely, selective cohort growth is anticipated, most prominently in the 85 and over bracket with a projected rise of 89 people.
Frequently Asked Questions - Population
Detail
Building approval figures compiled by AreaSearch indicate that Mount Crosby averages approximately 3 dwellings approved annually, totaling 16 homes across the prior 5 financial years (between FY-21 and FY-25) with 6 recorded to date in FY-25. With an average influx of 4.9 new residents per year per dwelling built over the past 5 financial years (between FY-21 and FY-25), local housing demand outpaces new building supply, putting upward pressure on property values and buyer competition while average construction costs stand at $493,000. Residential construction per capita in Mount Crosby sits significantly below regional norms, trailing Greater Brisbane by 81.0%.
This limited supply pipeline supports existing asset values, despite a slight uptick in recent approval activity. Lower volumes compared to national figures also suggest a mature market facing potential development barriers. Additionally, recent residential approvals have consisted exclusively of detached houses, preserving the neighborhood's low-density profile and attracting buyers seeking larger allotments. The presence of 329 people per approved dwelling highlights the quiet, subdued nature of local construction. Given expectations of a flat or contracting population trajectory, Mount Crosby is likely to experience easing residential demand, potentially offering favorable conditions for incoming purchasers.

1,286 residents of Mount Crosby are employed, from a labour force of 1,295. Unemployment sits at 0.7%, with participation at 80.6%. 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 1,434, 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
Mount Crosby features a well-educated workforce, with professional services showing strong representation, an unemployment rate of just 0.7%, and 11.1% in estimated employment growth over the past year, based on AreaSearch aggregation of statistical area data. As of March 2026, 1,286 residents are in work while the unemployment rate is 3.6% below Greater Brisbane's rate of 4.3%, and workforce participation is well beyond standard (80.6% compared to Greater Brisbane's 70.1%). Based on Census responses, a high 26.9% of residents were found to work from home, though Covid-19 lockdown impacts should be considered.
Local workers are predominantly engaged across health care & social assistance, education & training, alongside professional & technical services. Education & training represents a key specialty, commanding a workforce concentration 1.4 times the regional figure. By contrast, transport, postal & warehousing represents only 2.4% of the working population, trailing Greater Brisbane's 5.6%. Comparing Census workplace counts against resident worker counts suggests few employment hubs exist within the immediate boundary. SALM and ABS metrics aggregated across statistical boundaries show that over the 12 months to March 2026, local employment grew 11.1% against a 10.7% expansion in the labour force, pushing unemployment down by 0.2 percentage points. Over the same timeline, Greater Brisbane recorded a 3.2% increase in employment, a 3.4% rise in the labour pool, and a 0.1 percentage points rise in unemployment. Looking ahead, Jobs and Skills Australia national projections from Mar-26 provide context for local industry trajectories. Nationally, employment is projected to expand 6.6% over five years and 13.7% over ten years. Weighting these sectoral forecasts against Mount Crosby's existing industry distribution indicates potential local job growth of 7.0% over five years and 14.3% over ten years.

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 Aug 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 Aug 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.
