Twin Waters

Population growth drivers in Twin Waters are above average based on AreaSearch's ranking of recent, and medium to long-term trends

As of May 2026, the estimated population of Twin Waters is around 3,145, reflecting an increase of 179 people since the 2021 Census which reported a population of 2,966. This change is inferred from AreaSearch's estimation of the resident population at 3,141 following examination of the ABS's latest ERP data release in June 2025 and an additional 60 validated new addresses since the Census date. The population density ratio is approximately 802 persons per square kilometer, comparable to averages seen across locations assessed by AreaSearch. Over the past decade, Twin Waters has demonstrated resilient growth patterns with a compound annual growth rate of 1.5%, outpacing the Rest of Qld. Overseas migration contributed approximately 93.0% of overall population gains during recent periods. AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022, and Queensland State Government's SA2 area projections released in 2023 based on 2021 data for areas not covered by this data and years post-2032.

Age category splits are applied proportionally using ABS Greater Capital Region projections released in 2023 based on 2022 data when state projections are utilised. Looking ahead, population projections indicate an expected increase just below the median of national non-metropolitan areas by 262 persons to 2041, reflecting a gain of 8.2% over the 16 years.

Recent residential development output has been above average within Twin Waters when compared nationally

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, indicates Twin Waters has seen approximately 38 new homes approved annually. Between FY21 and FY25, around 194 homes were approved, with an additional 3 approved in FY26 so far.

On average, 0.7 new residents arrive per year for each new home over the past five financial years. This suggests supply is meeting or exceeding demand, offering greater buyer choice while supporting potential population growth above projections. New properties are constructed at an average expected cost of $503,000, slightly above the regional average, indicating a focus on quality developments. Compared to the Rest of Qld, Twin Waters shows 62.0% higher building activity per person, providing ample choice for buyers. This is well above the national average, reflecting strong developer confidence in the area.

New development consists of 73.0% detached houses and 27.0% attached dwellings, maintaining the area's traditional low density character with a focus on family homes appealing to those seeking space. With around 59 people per approval, Twin Waters reflects a low-density area. Population forecasts indicate Twin Waters will gain approximately 258 residents by 2041, 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.

This contrasted with Regional Qld where employment rose by 0.7% and labour force grew by 1.0%. Jobs and Skills Australia's national employment forecasts from May-25 projected national employment growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Twin Waters' employment mix suggested local employment should increase by 7.0% over five years and 14.3% over ten years, though these are simple extrapolations for illustrative purposes only and do not account for localized population projections.
