Mermaid Waters

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

As per ABS population updates for the broader area and new addresses validated by AreaSearch, the estimated population of Mermaid Waters is around 14,316 as of May 2026. This figure reflects an increase of 1,228 people (9.4%) since the 2021 Census, which reported a population of 13,088 people. The change is inferred from the resident population of 14,301 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2025 and an additional 300 validated new addresses since the Census date. This level of population equates to a density ratio of 2,033 persons per square kilometer, exceeding the average seen across national locations assessed by AreaSearch. The suburb's 9.4% growth since the 2021 census exceeded the Rest of Qld (9.2%) and the national average, marking it as a growth leader in the region. Population growth was primarily driven by overseas migration contributing approximately 65.0% of overall population gains during recent periods, although all drivers including natural growth and interstate migration were positive factors.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. 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. It is noted that these state projections do not provide age category splits; hence proportional growth weightings in line with the ABS Greater Capital Region projections released in 2023 based on 2022 data are applied for each age cohort where utilised. Future population trends forecast a significant increase in the top quartile of regional areas across the nation, with Mermaid Waters expected to expand by 3,643 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 25.3% in total over the 16 years.

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

Mermaid Waters has an average annual dwelling approval rate of around 54 based on AreaSearch analysis of ABS building approval numbers. Over the past five financial years, from FY21 to FY25, approximately 273 homes were approved, with a further 1,056 approved in FY26 so far. Each year, an average of 4.7 people move to the area for each dwelling built during these five years.

This significant demand is outpacing supply, leading to heightened buyer competition and pricing pressures. The average construction cost value of new properties is $1,370,000, indicating a focus on the premium segment with upmarket properties. In FY26, commercial approvals totalled $7.0 million, suggesting limited commercial development focus compared to residential. Mermaid Waters records markedly lower building activity than the rest of Queensland, at 69.0% below the regional average per person. This scarcity of new dwellings typically strengthens demand and prices for existing properties. Recent construction comprises 37.0% detached houses and 63.0% townhouses or apartments, marking a significant shift from the current housing pattern of 60.0% houses.

This focus on higher-density living creates more affordable entry points and caters to downsizers, investors, and first-home buyers. However, with around 450 people per dwelling approval, Mermaid Waters shows a developed market. Looking ahead, AreaSearch's latest quarterly estimate projects Mermaid Waters' population to grow by 3,628 residents through to 2041. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.

In the past year, employment increased by 2.8%, alongside labour force growth of 2.7%, reducing the unemployment rate by 0.1 percentage points. Regional Qld experienced lower employment and labour force growth, with a rise in unemployment rate.

Applying these projections to Mermaid Waters' employment mix indicates local employment should increase by 6.7% over five years and 13.7% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not account for localized population projections.
