AreaSearch is adopting 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 are adopted, released in 2023 and based on 2021 data. It should be noted that these state projections do not provide age category splits; hence where utilised, AreaSearch is applying proportional growth weightings in line with the ABS Greater Capital Region projections for each age cohort, released in 2023 based on 2022 data. 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 averaged approximately 18 new dwelling approvals annually over the past five financial years, totalling 92 homes. As of FY-26, 17 approvals have been recorded. On average, 3.6 new residents arrived per year for each dwelling constructed between FY-21 and FY-25. This suggests demand exceeding supply, which typically leads to price growth and increased buyer competition.

New properties are constructed at an average expected cost of $325,000. In the current financial year, $4.1 million in commercial approvals have been registered, indicating the area's residential character. Compared to Greater Brisbane, Cornubia-Carbrook has significantly less development activity, 53.0% below the regional average per person. This constrained new construction usually reinforces demand and pricing for existing dwellings. Nationally, this is also lower, reflecting market maturity and possible development constraints.

New development consists of 85.0% detached dwellings and 15.0% townhouses or apartments, maintaining the area's low density nature with a focus on detached housing attracting space-seeking buyers. The estimated population per dwelling approval is 735 people, reflecting its quiet, low activity development environment. Future projections indicate Cornubia-Carbrook adding approximately 361 residents by 2041, based on 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.
