Marmion

Marmion has seen population growth performance typically on par with national averages when looking at short and medium term trends

Based on an assessment of ABS population statistics for the surrounding region, alongside new address points verified by AreaSearch since the Census, the resident count in the suburb of Marmion is projected to be approximately 2,621 in May 2026. This represents an addition of 231 individuals (9.7%) compared to the 2021 Census, when the headcount stood at 2,390. This adjustment is calculated from a base resident population of 2,618, estimated by AreaSearch using the ABS demographic update from June 2025, combined with 6 validated new addresses established post-Census. Such a population size results in a density of 2,279 persons per square kilometer, which exceeds the typical density of domestic locations analyzed by AreaSearch. The growth rate of 9.7% since the 2021 census was quicker than the national benchmark of 9.3%, positioning the suburb as a local growth frontrunner. The upward trajectory was largely underpinned by arrival numbers from overseas, which accounted for roughly 85.0% of the aggregate demographic gains in recent times.

AreaSearch incorporates projections from the ABS and Geoscience Australia for each SA2 region, published in 2024 with 2022 serving as the baseline year. For SA2 territories lacking this coverage, and to calculate development beyond 2032, AreaSearch applies age cohort growth trends from the ABS Greater Capital Region projections published in 2023 using 2022 figures. Looking at long-term demographic shifts, the suburb of Marmion is set to experience expansion exceeding the national median, with local numbers projected to climb by 330 residents by 2041 under combined SA2 projections, representing a total increase of 12.5% over the 16 years.

Residential development activity is slightly higher than average within Marmion when compared nationally

According to AreaSearch's evaluation of ABS residential building approvals distributed from local statistical data, the suburb of Marmion has averaged approximately 8 residential approvals annually, yielding a total of 43 dwellings over the preceding 5 financial years. Thus far in FY-26, 5 permits have been logged. With an average of 3.9 additional residents per year for each completed dwelling over the 5 financial years from FY-21 to FY-25, demand outpaces supply, a dynamic that commonly drives upward price movements and heightens competition among buyers, even as new construction averages a cost of $918,000, indicating that builders are targeting the luxury market with high-end designs. Furthermore, commercial approvals totaling $3.4 million have been documented during the current financial year, highlighting the suburb's overwhelmingly residential focus.

In comparison to Greater Perth, the suburb of Marmion displays a matching level of per capita construction activity, keeping the local market in equilibrium with the wider metropolitan region. This volume sits below the national benchmark, pointing to the mature nature of the locality and implying potential regulatory constraints on new building. The composition of new approvals consists of 56.0% detached houses and 44.0% multi-unit dwellings, showcasing a rising proportion of medium-density options that provide various price points, ranging from large family spaces to compact, entry-level properties. This marks a clear departure from the suburb's historical housing stock, which is 83.0% detached houses, demonstrating a scarcity of vacant land alongside shifting lifestyles and a demand for more diverse, economical housing choices. With a ratio of approximately 247 people per dwelling approval, the suburb of Marmion presents a growing real estate market.

Long-term forecasts suggest the suburb of Marmion will add 327 residents by 2041, based on the latest quarterly calculations from AreaSearch. If building activity remains at its current pace, housing additions may fall short of demographic growth, which is likely to heighten competition among buyers and support rising property values.

Conversely, retail jobs are less common, accounting for 7.4% of the workforce compared to the metropolitan standard of 9.3%. This mostly residential community offers sparse local employment possibilities, as shown by comparing the Census working population against the total resident workforce.

According to AreaSearch's analysis of SALM and ABS statistics aggregated from regional divisions, the 12-month timeframe saw a 3.4% rise in employment and a 3.5% expansion of the labor pool, leading to a minor 0.1 percentage point increase in the unemployment rate. By comparison, Greater Perth experienced a 2.0% increase in jobs, a 2.5% expansion of the workforce, and a 0.4 percentage point rise in unemployment. Long-term employment projections published by Jobs and Skills Australia in May-25 offer additional context on future labor needs in the suburb of Marmion. These projections, spanning five and ten-year horizons, have been applied to the local workforce structure to predict future trends. While national employment is projected to grow by 6.6% over five years and 13.7% over ten years, growth rates vary widely by industry. Projecting these industry trends onto the local labor profile indicates that employment in the suburb of Marmion should expand by 6.7% over five years and 13.7% over ten years, assuming a basic weighted model that does not account for local population changes.
