New office supply in Adelaide is building (+142% year-on-year). A rising pipeline is the risk to watch: more product competing for the same tenants pressures rents and values.

Precinct by precinct

Across 69 Adelaide office precincts, the current tilt is 18 tightening · 17 demand-led · 22 quiet · 12 oversupply risk (median supply change -42% year-on-year). This is a stock-picker's market: the pressure is uneven, not uniform.

Watch (oversupply risk): Salisbury, Onkaparinga, Tea Tree Gully, Playford

The sector backdrop

Valuations lag rates — capital softening still to come; income cushions it. Office cap rates sit around 6.32% on our national read. Conditions are neutral / transitional on our macro read.

Cap rate = the yearly income as a share of price (a higher number is cheaper). The number above is a market read; where our model puts fair value, and the five-year return forecast, are in the report.
