This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Population
Marmion has seen population growth performance typically on par with national averages when looking at short and medium term trends
As of Feb 2026, the estimated population of the suburb of Marmion is around 2,635. This figure reflects a growth of 245 people since the 2021 Census, which reported a population of 2,390. The increase was inferred from AreaSearch's estimation of the resident population at 2,582 in Jun 2024, along with six validated new addresses since the Census date. This results in a population density ratio of 2,291 persons per square kilometer, higher than the average seen across national locations assessed by AreaSearch. Marmion's growth rate of 10.3% since the 2021 Census exceeds the national average of 9.9%. Overseas migration contributed approximately 85.0% of overall population gains during recent periods.
AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data and post-2032 growth estimation, AreaSearch utilises ABS Greater Capital Region projections released in 2023 based on 2022 data. Future population trends project an above median growth for the area, with an expected increase of 346 persons to 2041, reflecting a total increase of 10.4% over the 17 years.

Development
Residential development activity is slightly higher than average within Marmion when compared nationally
Based on AreaSearch analysis using ABS building approval data, Marmion averaged approximately 9 new dwelling approvals annually over the past five financial years, totalling an estimated 48 homes. As of FY26, 4 approvals have been recorded. Historically, each dwelling has attracted around 3 new residents per year on average between FY21 and FY25. This robust demand supports property values, with new homes valued at approximately $918,000, indicating a focus on premium properties.
In the current financial year, $3.4 million in commercial approvals have been registered, reflecting Marmion's primarily residential nature. Compared to Greater Perth, Marmion has shown slightly higher development activity, with 21.0% more approvals per person over the past five years. This maintains good buyer choice while supporting existing property values. Recent construction comprises 60.0% detached houses and 40.0% medium and high-density housing, marking a significant shift from the current pattern of 83.0% houses.
This change suggests diminishing developable land availability and responds to evolving lifestyle preferences and affordability needs. Marmion has approximately 187 people per dwelling approval, indicating an expanding market. According to AreaSearch's latest quarterly estimate, Marmion is expected to grow by 275 residents by 2041. Current development levels appear aligned with future requirements, maintaining stable market conditions without significant price pressures.
