Best Adelaide suburbs for first-home buyers

Plympton leads the list on a median of $542,000. Across the full ranking, entry prices run from $459,000 to $925,000. These 30 suburbs came from a field of 186 eligible Adelaide suburbs.

Each eligible Adelaide suburb is scored on five factors: 35% affordability (median price as a percentile within Adelaide — cheaper suburbs score higher), 20% OpenStreetMap-derived walkability, 15% growth (2016→2021 population and dwelling change combined), 15% safety (bushfire, crime and flood risks combined), and 10% CBD access (drive-time to the CBD). A small volume bonus rewards suburbs with deeper listing inventory so buyers have real choice.

The price gap between a median house and a median unit is usually 30–50 percent in Australian metros, and buyers self-select strongly on the house-vs-unit choice before shortlisting suburbs. Blending the two into one score would hide the signal each type of buyer is actually looking for, so we publish both lists on the same page.

To appear on the list, a suburb needs a resident population of at least 1,000, at least 5 listings of the property type in the last 6 months (so we're not ranking a market with one sale), and a composite safety score of at least 30/100 — bushfire, crime and flood risks combined. The safety gate stops a genuinely dangerous suburb winning on price alone.

The top 15 is recomputed after each property-listings refresh — monthly on the 1st. Growth and safety inputs refresh alongside the underlying ABS census and state-government risk datasets.
