Twin Waters

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

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch since Nov 2025, Twin Waters statistical area's population is estimated at around 3,089. This reflects an increase of 123 people (4.1%) since the 2021 Census which reported a population of 2,966 people. The change is inferred from the resident population of 3,073 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 60 validated new addresses since the Census date. This level of population equates to a density ratio of 788 persons per square kilometer, which is relatively in line with 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 2.6%, outpacing the SA3 area. Population growth for the area was primarily driven by overseas migration that contributed approximately 93.0% of overall population gains during recent periods.

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. Looking at population projections moving forward, a population increase just below the median of national non-metropolitan areas is expected, with Twin Waters (SA2) expected to grow by 270 persons to reach approximately 3,359 people by 2041 based on aggregated SA2-level projections, reflecting a gain of 10.3% in total over the 17 years.

AreaSearch assessment of residential approval activity sees Twin Waters among the top 30% of areas assessed nationwide

Based on AreaSearch analysis using ABS building approval numbers from statistical area data, Twin Waters has seen approximately 41 new homes approved each year. Over the past five financial years, between FY2021 and FY2025, around 209 homes were approved, with an additional three approved so far in FY2026.

On average, 1.3 new residents arrive per new home annually over these five years, indicating a balanced supply and demand market that supports stable conditions. The average construction value of new properties is $503,000, slightly above the regional average, suggesting a focus on quality developments. Compared to the Rest of Qld, Twin Waters has 75.0% higher building activity per person, offering buyers ample choice and reflecting strong developer confidence in the area. The new development composition consists of 71.0% detached houses and 29.0% attached dwellings, maintaining the area's traditional low density character with a focus on family homes. With around 53 people per approval, Twin Waters reflects a low-density area.

According to AreaSearch's latest quarterly estimate, population forecasts indicate Twin Waters will gain approximately 318 residents by 2041. Given current development patterns, new housing supply should readily meet demand, offering good conditions for buyers and potentially facilitating population growth beyond current projections.
