Thorneside

An assessment of population growth drivers in Thorneside reveals an overall ranking slightly below national averages considering recent, and medium term trends

Thorneside's population is around 4034 as of February 2026, reflecting an increase of 157 people since the 2021 Census which reported a population of 3877. This change is inferred from the estimated resident population of 4028 in June 2024 and five additional validated addresses since the Census date. The population density ratio is 1510 persons per square kilometer, above the average seen across national locations assessed by AreaSearch. Over the past decade, Thorneside has shown resilient growth patterns with a compound annual growth rate of 0.5%, outpacing the SA3 area. Natural growth contributed approximately 52.7% of overall population gains during recent periods. AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area released in 2024, based on 2022 data.

For areas not covered by this data and years post-2032, Queensland State Government's SA2 area projections released in 2023 based on 2021 data are adopted. These state projections do not provide age category splits, so AreaSearch applies proportional growth weightings in line with ABS Greater Capital Region projections for each age cohort released in 2023 based on 2022 data. Future population trends suggest lower quartile growth of statistical areas across the nation, with Thorneside expected to expand by 89 persons to 2041 based on latest annual ERP population numbers, reflecting a total increase of 2.1% over the 17 years.

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

Thorneside has averaged approximately 11 new dwelling approvals per year. Over the past five financial years, from FY21 to FY25, a total of 57 homes were approved, with an additional 8 approved in FY26 so far.

Each dwelling built over these years has resulted in an average of 2 new residents per year, indicating strong demand that supports property values. The average construction cost value of new homes is $330,000. Compared to Greater Brisbane, Thorneside has seen 14.0% less new development per person. Nationally, it ranks at the 27th percentile for areas assessed, suggesting limited buyer options and increased demand for established dwellings.

This is below the national average, implying the area's established nature and potential planning limitations. All new construction in Thorneside has been detached houses, maintaining its traditional suburban character focused on family homes. Interestingly, developers are building more traditional houses than the current mix suggests (64.0% at Census), indicating continued strong demand for family homes despite density pressures. With around 585 people per dwelling approval, Thorneside reflects a highly mature market. By 2041, it is projected to gain approximately 83 residents based on AreaSearch's latest quarterly estimate. Given current development patterns, new housing supply should readily meet demand, offering good conditions for buyers and potentially facilitating population growth beyond current projections.
