Cornubia - Carbrook has seen population growth performance typically on par with national averages when looking at short and medium term trends

Based on AreaSearch's analysis, Cornubia - Carbrook's population is around 9,528 as of Feb 2026. This reflects an increase of 452 people (5.0%) since the 2021 Census, which reported a population of 9,076 people.

This population level equates to a density ratio of 253 persons per square kilometer, providing significant space per person and potential room for further development.

AreaSearch adopts 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 applies proportional growth weightings in line with the ABS Greater Capital Region projections (released in 2023, based on 2022 data) for each age cohort. As we examine future population trends, lower quartile growth of Australian statistical areas is anticipated, with the area expected to grow by 424 persons to 2041 based on the latest annual ERP population numbers, reflecting a gain of 3.8% in total over the 17 years.

Residential development activity is lower than average in Cornubia - Carbrook according to AreaSearch's national comparison of local real estate markets

Cornubia - Carbrook has averaged around 18 new dwelling approvals each year, totalling 92 homes over the past 5 financial years. So far in FY-26, 21 approvals have been recorded. Given an average of 3.6 new residents per year arriving per dwelling constructed over the past 5 financial years (between FY-21 and FY-25), demand significantly exceeds new supply, which usually results in price growth and increased buyer competition, while new properties are constructed at an average value of $325,000. Additionally, $4.1 million in commercial approvals have been registered this financial year, reflecting the area's residential character.

Compared to Greater Brisbane, Cornubia - Carbrook has significantly less development activity (53.0% below regional average per person). This constrained new construction usually reinforces demand and pricing for existing dwellings. This is likewise lower than the national average, reflecting market maturity and pointing to possible development constraints. New development consists of 85.0% detached dwellings and 15.0% townhouses or apartments, preserving the area's low density nature with an emphasis on detached housing attracting space-seeking buyers. The estimated count of 735 people in the area per dwelling approval reflects its quiet, low activity development environment.

Future projections show Cornubia - Carbrook adding 361 residents by 2041 (from the latest AreaSearch quarterly estimate). At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
