Statistical Area (SA2) Boundary Analysis

This analysis uses ABS Statistical Areas Level 2 (SA2) boundaries, which can materially differ from Suburbs and Localities (SAL) even when sharing similar names.

SA2 boundaries are defined by the Australian Bureau of Statistics and are designed to represent communities for statistical reporting (e.g., census and ERP).

Suburbs and Localities (SAL) represent commonly-used suburb/locality names (postal-style areas) and may use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

DemographicsPopulation Growth in Diddillibah - Rosemount

Table Chart PROFILE FAQ

Diddillibah - Rosemount has an estimated 4,733 residents, up from 4,403 at the 2021 Census — a change of 330 people, or 7.5%. Growth has averaged 1.8% a year over five years. Overseas migration accounts for 50.7% of that increase. That puts 151 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 investigations by AreaSearch, Diddillibah - Rosemount has a population of approximately 4,733 as of May 2026. This represents a growth of 330 people (7.5%) from the 2021 Census, when the population was recorded at 4,403 people. This population variance is calculated from the ABS June 2025 estimated resident population of 4,731 and an extra 20 validated new addresses added since the Census. With these figures, the population density stands at 151 persons per square kilometer, indicating low density living conditions and room for potential expansion. Over the previous ten years, Diddillibah - Rosemount recorded steady growth with a compound annual growth rate of 2.2%, ahead of the Rest of Qld.

Recent population gains were mostly driven by overseas migration, which made up around 50.7% of the total increase, though interstate migration and natural growth also registered positive results. AreaSearch incorporates SA2 projections published by ABS and Geoscience Australia in 2024 using 2022 as the base year. Where SA2 data is unavailable or for projections after 2032, Queensland State Government projections released in 2023 based on 2021 numbers are used. Because these state figures do not split populations into age brackets, AreaSearch scales age groups using proportional weightings derived from the ABS Greater Capital Region projections (published in 2023 using 2022 data). Demographic outlooks suggest the area will see a population rise slightly below the median of regional localities in Australia, with the local population projected to increase by 484 persons to 2041 using the latest annual ERP statistics, which corresponds to an overall rise of 10.2% across the 16 years.

Residential SupplyHousing Development & Building Approvals in Diddillibah - Rosemount

Table Chart PROFILE FAQ

121 new dwellings have been approved in Diddillibah - Rosemount over the past five years, an average of 24 a year. That places the area in the 56th percentile for residential development activity nationally, about 5 approvals per 1,000 residents a year. Approvals are currently running at an annualised 19, broadly in line with that longer-run average. Figures come from ABS building approvals aggregated to this SA2 boundary and are updated monthly as the ABS releases them.

Detail

Diddillibah - Rosemount averages approximately 24 building approvals for residential dwellings annually, totaling 121 approvals during the past 5 financial years. In the current FY-26 period, 18 approvals have been logged. As an average of 3.3 people moved to the region for every finished home over the past 5 financial years (between FY-21 and FY-25), demand is outstripping supply, a trend that typically drives upward price pressure and intensifies competition, with new properties being built at an average value of $387,000. Additionally, commercial building approvals have reached $3.3 million during this financial year, indicating that the area maintains its primarily residential character.

Compared with the broader rest of Queensland, Diddillibah - Rosemount exhibits roughly three quarters the building activity per capita and ranks in the 47th percentile among nationally evaluated regions, which limits buyer options and fuels demand for current dwellings. All recent construction in the area involves standalone homes, maintaining the locality's low density character and drawing buyers who prioritize spacious detached housing. The estimated population of 374 people per dwelling approval underscores the area's tranquil and low intensity development profile. Projections indicate that Diddillibah - Rosemount will add 482 residents by 2041 (derived from the most recent AreaSearch quarterly figures). At current rates of building activity, residential supply is positioned to satisfy demand, which should support buyers and could possibly facilitate growth that outpaces current predictions.

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 — 20 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (4,403 at the 2021 Census → 4,733 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.

Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (316071546). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.

Common questions about this page

Why can the Diddillibah - Rosemount SA2 boundary differ from the suburb boundary?
This page uses ABS Statistical Area Level 2 (SA2) boundaries for statistical reporting (e.g., census and ERP). SA2 areas can differ materially from Suburbs and Localities (SAL) boundaries, even when they share similar names, because they are defined for different purposes and often use different geographic boundaries.
Where does the data on this Diddillibah - Rosemount page come from?
AreaSearch compiles this page from official and industry sources — including ABS, Geoscience Australia, Valuer General, Provider directories, DEWR, JSA, State Transport Departments and ACARA — then aggregates them to the boundary shown and calculates the rankings, growth rates and benchmarks itself. Property sales come from the state valuation authority, rents from state rental bond lodgements, development applications from council and state planning portals, school data from ACARA, and public transport from state transport departments.
Is the Diddillibah - Rosemount data on this page just from the 2021 Census?
No. Most of this page is maintained well beyond the Census. Sourced entirely from current releases: development & approvals (Jun 2026), property sales & rents (Aug 2026), infrastructure projects (Aug 2026) and services & amenities (Jul 2026). Built on a Census baseline but carrying newer measures on top: population (to May 2026), age profile (to May 2026), employment (to Mar 2026), income (to FY 2023), education (to Aug 2026), transport (to Jul 2026) and health (to 2024). Population and age cohorts in particular are re-based to the latest ABS Estimated Resident Population rather than left at 2021 counts. Only housing, households and cultural diversity remain wholly Census-based, because no more current small-area dataset exists for those measures.
