Marleston
With a population of 1,950 packed into just 0.97 square kilometres, Marleston ranks among Adelaide's denser inner suburbs at 2,019 residents per km2. Nearly half of residents hold university qualifications (47%), which is 16.9 percentage points above the national average, yet household income sits only in the 41.7th percentile nationally, a gap that partly explains a 47.2% renter share well above the national norm. The suburb's healthcare sector employs 21% of working residents, the single largest industry, anchoring its economy close to the nearby Queen Elizabeth Hospital precinct.

Median 1Q 2026
The median house price reached $982,000 in Q1 2026, down 2.8% from a peak of $1,010,000 in Q1 2025, giving buyers a modest entry opportunity compared to the recent high. Dwellings split roughly evenly between separate houses (50.2%) and attached stock, with semi-detached homes at 31.3% and apartments at 18.5%. Two and three-bedroom homes each account for around 43-44% of stock, so four-bedroom family homes are rare at just 7.5%. Monthly mortgage repayments average $1,528, and the mortgage-to-income ratio of 24.9% sits below the 30% stress threshold, making purchase costs manageable relative to local incomes.

For Investors
Marleston's 47.2% renter share is well above the national average, underpinning consistent tenant demand. Weekly rent of $290 is modest against the $982,000 median, implying a gross yield around 1.5%, so the investment case leans toward capital growth rather than income. The vacancy rate of 6.7% is elevated compared to the Adelaide metro average, which warrants monitoring before committing. Development activity was modest at 15 applications in the past 12 months, so supply pressure is low, and the high overseas-born proportion (40.2%, some 18.6 points above national) sustains rental demand from new arrivals.

Demographics
The median age of 37 is 3 years younger than the national figure, a reflection of the suburb's university-educated, renter-heavy profile. Overseas-born residents make up 40.2% of the population, which is 18.6 percentage points above the national average, and English (492), Indian (158), Chinese (155) and Italian (133) ancestries all feature significantly. Among languages spoken at home, Greek, Mandarin and Punjabi each have around 40 speakers, signalling genuine multicultural breadth. Average household size of 2.1 is 0.4 below national, consistent with the strong couples-without-children presence (33.2% of families) and the 5.2% share of small one-bedroom dwellings.

Tenure
Tenure divides clearly: 47.2% rent, 30.5% carry a mortgage and 22.4% own outright, a renter-majority profile well above the national owner-occupier norm. Separate houses account for 50.2% of stock, a higher house proportion than many comparable inner suburbs, while semi-detached homes add 31.3% and apartments 18.5%. The median house price fell 2.8% from $1,010,000 (Q1 2025) to $982,000 (Q1 2026). Two-bedroom and three-bedroom dwellings together represent about 87% of all homes, so large family homes are scarce. At a rent-to-income ratio of 20.5%, renters face no rent stress by standard benchmarks, which is below the 30% stress threshold.

Economy & Employment
Healthcare employs 21.0% of local workers, the highest share of any single industry and well above the typical suburban figure, anchored by proximity to major hospital infrastructure. Professional/Technical services (8.9%), Hospitality (8.7%), Education (8.5%) and Public Administration (7.8%) round out the top five, giving a balanced public-sector and knowledge-economy mix. Professionals are the largest occupation group at 263 workers, followed by Community/Personal service (160) and Clerical/Admin (140). The unemployment rate is 4.6% and the full-time employment rate is 59.7%, both in a normal range. Household income in the 41.7th percentile nationally sits lower than the education profile might predict, partly because healthcare and community work roles carry moderate rather than high salaries.

Transport to Work
Car travel dominates at 76.4% of commuters, though 9.7% use public transport and 6.5% walk or cycle, above-average active transport for Adelaide. No schools are recorded inside the suburb boundary, so families depend on institutions in adjoining suburbs. The crime rate is 82.6 incidents per 1,000 residents based on 161 recorded offences, a rate that should be read in context of the suburb's high residential density compared to the SA state average. Volunteering participation of 14.2% and a rent-to-income ratio of 20.5% (below the 30% stress threshold) suggest a reasonably stable community, while the need-for-assistance rate of 11.2% (212 people) is broadly consistent with the older-established pockets within the suburb.

How to read these comparisons
Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.
Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.
Data sources: ABS 2021 Census (demographics, income, tenure), state Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
