Marino

An assessment of population growth drivers in Marino reveals an overall ranking slightly below national averages considering recent, and medium term trends

As of Nov 2025, Marino's population is estimated at around 2,363 by AreaSearch following analysis of ABS population updates and new addresses validated since the Census. This reflects an increase of 86 people from the 2021 Census figure of 2,277. The change was inferred from the resident population estimate of 2,363 based on examination of the latest ERP data release by the ABS (June 2024) and two additional validated new addresses since the Census date. Marino's population density is approximately 682 persons per square kilometer, comparable to averages seen across other locations assessed by AreaSearch. The suburb experienced a population growth rate of 3.8% since the census, which is within 1.6 percentage points of the SA4 region's growth rate of 5.4%. Overseas migration contributed approximately 65.0% of Marino's overall population gains during recent periods.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area as released in 2024 with a base year of 2022, and uses the SA State Government's Regional/LGA projections by age category released in 2023 based on 2021 data for areas not covered by ABS data or years post-2032. Considering these projections, Marino is expected to experience population growth just below the national median, with an increase of 153 persons to 2041, reflecting a total increase of 6.6% over the 17-year period.

AreaSearch analysis of residential development drivers sees Marino recording a relatively average level of approval activity when compared to local markets analysed countrywide

Based on AreaSearch analysis of ABS building approval numbers allocated from statistical area data, Marino has experienced around 5 dwellings receiving development approval each year over the past five financial years, totalling an estimated 27 homes. As of FY-26, 7 approvals have been recorded. On average, 3.4 people move to the area annually for each dwelling built between FY-21 and FY-25, indicating demand significantly exceeds new supply, which typically results in price growth and increased buyer competition.

New properties are constructed at an average expected cost of $475,000, slightly above the regional average, suggesting a focus on quality developments. Relative to Greater Adelaide, Marino shows substantially reduced construction, with 68.0% below the regional average per person, reflecting market maturity and possible development constraints. New building activity comprises 86.0% detached houses and 14.0% medium and high-density housing, preserving the area's low density nature and attracting space-seeking buyers. With around 261 people per dwelling approval, Marino shows characteristics of a low density area. According to AreaSearch's latest quarterly estimate, Marino is expected to grow by 155 residents through to 2041.

Building activity is keeping pace with growth projections, though buyers may experience heightened competition as the population grows.

Employment growth over the past year was estimated at 2.2%. As of June 2025, 1,283 residents are employed, with an unemployment rate of 1.9% below Greater Adelaide's and workforce participation similar to Greater Adelaide's 61.7%.

Employment opportunities locally appear limited based on Census working population vs resident population comparison. Over the 12 months to June 2025, employment increased by 2.2%, labour force by 2.5%, leading to a unemployment rise of 0.3 percentage points. In contrast, Greater Adelaide had employment and labour force growth of 2.1%. Jobs and Skills Australia's national employment forecasts from Sep-22 project national employment expansion at 6.6% over five years and 13.7% over ten years. Applying these projections to Marino's employment mix suggests local employment should increase by 7.0% over five years and 14.2% over ten years, though these are simple extrapolations for illustrative purposes and do not account for localized population projections.
