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

Mermaid Waters has seen approximately 59 dwellings granted development approval annually. Over the past five financial years, from FY21 to FY25295 homes were approved, with a further 1,006 approved in FY26 so far. On average, around 4.4 new residents have arrived per year for each dwelling constructed during these five years.

This indicates that supply is lagging behind demand, which typically results in increased buyer competition and pricing pressures. The average value of new homes being built is $783,000, suggesting developers are targeting the premium market with high-end developments. In FY26, commercial approvals totaling $14.0 million have been registered, indicating balanced commercial development activity. Compared to the rest of Queensland, Mermaid Waters has significantly lower building activity, at 67.0% below the regional average per person. This limited new supply generally supports stronger demand and values for established homes. Recent construction comprises 40.0% standalone homes and 60.0% medium and high-density housing, creating more affordable entry points and suiting downsizers, investors, and first-home buyers.

This marks a notable shift from the area's existing housing composition, currently at 59.0% houses, indicating decreasing availability of developable sites and reflecting changing lifestyles and demand for diverse, affordable housing options. With approximately 476 people per approval, Mermaid Waters indicates a mature market. According to the latest AreaSearch quarterly estimate, Mermaid Waters is projected to add 3,893 residents by 2041. If current construction levels continue, housing supply may lag behind population growth, potentially intensifying buyer competition and supporting price growth.
