Marino
With a median house price of $1,343,000 and 97.1% of dwellings as separate houses, Marino sits firmly among Adelaide's premium coastal suburbs, yet household income falls in the 79.1st percentile nationally, a gap that reveals how long-held ownership rather than current earnings drives wealth here. The median age of 47 is 7 years above the national figure, and 46.4% of residents own their home outright, the highest tenure category. SEIFA decile scores of 7-8 across all four indexes confirm above-average but not elite advantage. The suburb had 41 development applications in the past 12 months, indicating steady, renovation-focused activity in an otherwise stable coastal enclave.

The median house price of $1,343,000 as of Q1 2026 represents a 11.9% fall from the Q1 2025 peak of $1,525,000, giving buyers a more accessible entry point into this tightly held market. Stock is overwhelmingly detached houses at 97.1%, with 4-plus bedroom homes at 40.2% and 3-bedroom at 50.9%, meaning almost no unit alternative exists. Monthly mortgage repayments average $1,997, producing a mortgage-to-income ratio of 22.1%, below the 30% stress threshold, which reflects the high share of outright owners (46.4%) and modest renter base (10.8%). Compared to the broader SA median, this price tier is significantly higher, making Marino an aspirational coastal buy rather than a first-home option. The low 16.6% turnover rate shows existing owners are reluctant to sell.

The low 16.6% turnover rate shows existing owners are reluctant to sell.
For Investors
At just 10.8% of households, the renter base is thin compared to the national average, limiting rental demand. Weekly rent of $400 against a $1,343,000 median implies a gross yield below 1.6%, among the lowest return profiles. The vacancy rate of 6.8% is elevated, signalling limited competition for available rentals and reinforcing the owner-occupier character. Net overseas migration averages 101 per year, the primary growth driver, while net internal migration is negative at 44 persons annually. Development applications totalled 41 in the past 12 months, dominated by alterations and extensions to existing homes rather than new dwellings. The investment case rests on capital preservation in a supply-constrained coastal location, not yield.

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.
