Cornubia

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

Based on ABS population updates and AreaSearch validations, the suburb of Cornubia's estimated population is around 8,119 as of Feb 2026. This reflects an increase of 309 people since the 2021 Census, which reported a population of 7,810. The change is inferred from AreaSearch's resident population estimate of 8,059 in June 2024 and additional validated new addresses since the Census date. This level of population equates to a density ratio of 537 persons per square kilometer. Population growth was primarily driven by overseas migration contributing approximately 54.0% of overall gains.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered and years post-2032, Queensland State Government's SA2 area projections from 2023 based on 2021 data are used. Anticipating future dynamics, lower quartile growth is expected, with the suburb projected to expand by 287 persons to 2041, reflecting a gain of 3.8% over the 17 years.

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

Cornubia has averaged approximately 16 new dwelling approvals per year based on AreaSearch analysis of ABS building approval numbers. Over the past five financial years, from FY-21 to FY-25, an estimated 81 homes were approved, with a further 12 approved in FY-26. This results in an average of 3.3 people moving to the area per dwelling built annually over these years.

The demand for housing significantly outpaces supply, which typically drives up prices and increases competition among buyers. New homes are being constructed at an average value of $568,000, indicating that developers are targeting the premium market segment with higher-end properties. This financial year has seen $3.8 million in commercial approvals, suggesting the area's residential character. Compared to Greater Brisbane, Cornubia records markedly lower building activity, which is 52.0% below the regional average per person. This constrained new construction usually reinforces demand and pricing for existing homes.

Nationally, Cornubia also reflects lower building activity, indicating market maturity and possible development constraints. The area's new building activity comprises 86.0% standalone homes and 14.0% townhouses or apartments, maintaining its traditional low density character with a focus on family homes appealing to those seeking space. The estimated count of 706 people in the area per dwelling approval reflects its quiet, low activity development environment. Future projections show Cornubia adding 306 residents by 2041, according to 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.
