Marian

Marian lies within the top quartile of areas nationally for population growth performance according to AreaSearch analysis of recent, and medium to long-term trends

Based on analysis of ABS population updates for the Marian statistical area (Lv2), and new addresses validated by AreaSearch, Marian's estimated population is around 4,593 as of Nov 2025. This reflects an increase of 369 people (8.7%) since the 2021 Census, which reported a population of 4,224 people. The change is inferred from the resident population of 4,425 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 8 validated new addresses since the Census date. Marian's population density ratio is 55 persons per square kilometer. Marian's growth since the 2021 census exceeded the SA3 area (6.8%) and the SA4 region, marking it as a growth leader in the region. Population growth was primarily driven by natural growth contributing approximately 63.0% of overall population gains during recent periods.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area released in 2024 with 2022 as the base year. For areas not covered and years post-2032, Queensland State Government's SA2 area projections released in 2023 based on 2021 data are adopted. Considering projected demographic shifts, an above median population growth of locations outside capital cities is projected for Marian, with an expected increase of 899 persons to 2041 reflecting a total increase of 15.8% over the 17 years.

Residential development activity is lower than average in Marian according to AreaSearch's national comparison of local real estate markets

AreaSearch analysis of ABS building approval numbers shows Marian has recorded around 4 residential properties granted approval per year over the past 5 financial years, totalling an estimated 24 homes. So far in FY-26, 5 approvals have been recorded. Over these 5 years (FY-21 to FY-25), an average of 11 people moved to the area for each dwelling built. This high demand exceeds new supply, typically leading to price growth and increased buyer competition.

New properties are constructed at an average value of $513,000, higher than regional norms due to quality-focused development. In FY-26, there have been $2.1 million in commercial approvals, indicating minimal commercial development activity. Marian records markedly lower building activity compared to the Rest of Qld (70.0% below regional average per person). This limited new supply generally supports stronger demand and values for established properties. This activity is also under the national average, suggesting the area's established nature and potential planning limitations.

All new construction has been detached dwellings, maintaining Marian's traditional low density character with a focus on family homes. The estimated count of 882 people in the area per dwelling approval reflects its quiet development environment. Looking ahead, Marian is expected to grow by 726 residents through to 2041 (from AreaSearch's latest quarterly estimate). Should current construction levels persist, housing supply could lag population growth, likely intensifying buyer competition and underpinning price growth.

Jobs and Skills Australia's national employment forecasts from May-25 suggest that Marian's employment should increase by 5.3% over five years and 12.0% over ten years, based on a simple weighting extrapolation of industry-specific projections against Marian's employment mix.
