Twin Waters

Population growth drivers in Twin Waters are strong compared to national averages based on AreaSearch's ranking of recent, and medium to long-term trends

The population of Twin Waters, as estimated by AreaSearch using ABS updates and new addresses validated since the 2021 Census, is around 3,143 as of November 2025. This represents an increase of 177 people (6.0%) from the previous population count of 2,966 in 2021. The estimated resident population of 3,127, derived from AreaSearch's analysis of ABS's latest ERP data release in June 2024 and additional validated new addresses since the Census date, reflects this growth. This results in a population density ratio of approximately 801 persons per square kilometer, which is comparable to averages seen across other locations assessed by AreaSearch. Over the past decade, Twin Waters has shown consistent growth patterns with a compound annual growth rate of 2.6%, outperforming the broader SA3 area. The primary driver for this population growth was overseas migration, contributing approximately 93.0% of overall population gains during recent periods.

AreaSearch's projections for Twin Waters are based on ABS/Geoscience Australia estimates released in 2024 with a base year of 2022 for each SA2 area. For areas not covered by this data and years post-2032, Queensland State Government's SA2 area projections from 2023, based on 2021 data, are adopted. However, these state projections do not provide age category splits, so AreaSearch applies proportional growth weightings in line with ABS Greater Capital Region projections released in 2023 and based on 2022 data for each age cohort. Looking ahead, population projections indicate a growth of 306 persons to reach approximately 3,449 by the year 2041. This reflects an overall gain of 9.6% over the 17-year period, which is slightly below the median growth rate expected for non-metropolitan areas nationally.

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

Between FY21 and FY25, Twin Waters saw approximately 35 new homes approved annually. In total, around 177 homes were approved during these five financial years, with an additional three approvals in FY26 as of now. On average, each new home has brought in about 1.6 new residents per year over the past five financial years, indicating a balanced supply and demand market that supports stable conditions.

The average construction value for new properties is around $503,000, aligning with regional trends. This financial year has seen approximately $4.0 million in commercial approvals, suggesting limited focus on commercial development. Compared to the rest of Queensland, Twin Waters has shown slightly more development activity, with a 49.0% increase per person over the five-year period. This maintains good buyer choice and supports existing property values.

However, building activity has slowed in recent years. Twin Waters' new development consists of approximately 79.0% standalone homes and 21.0% townhouses or apartments, preserving the area's low-density nature with a focus on detached housing that attracts space-seeking buyers. The location currently has around 122 people per dwelling approval, indicating a low-density market. According to AreaSearch's latest quarterly estimate, Twin Waters is projected to gain approximately 300 residents by 2041. With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.

Employment opportunities appear limited locally, as indicated by Census working population vs resident population comparison.

By contrast, Rest of Qld recorded employment growth of 1.8% and labour force growth of 2.0%, with unemployment rising 0.2 percentage points. Jobs and Skills Australia's Sep-22 national employment forecasts project a 6.6% expansion over five years and 13.7% over ten years. Applying these projections to Twin Waters' employment mix suggests local employment should increase by 7.0% over five years and 14.3% over ten years, assuming constant population projections.
