Salisbury sits in northern Adelaide in postcode 5108, inside the City of Salisbury, with the Adelaide-Gawler train line running through it. The reading is SEIFA decile 1 at IRSAD 842, in the 4th state percentile within South Australia.
ABS 2021 IRSAD release. Score 842 (national mean = 1000).
Decile 1 in the 4th state percentile is a clear lower-band reading. Salisbury has a long-established affordability profile in northern Adelaide, with a mix of detached housing stock, public-housing legacy, and a train-line connection that anchors the rental market. PropertyRanker uses SEIFA as a primary signal for economic_strength, hazard_risk, and entry_point_risk. A decile 1 reading drags the score on those three criteria, materially. What partially balances it for Salisbury is the rental_market_depth criterion. The combination of train-line access, ongoing infrastructure spending in the broader Salisbury LGA, and the suburb's proximity to the Mawson Lakes education precinct supports rental absorption more reliably than the SEIFA reading alone would suggest. The strategy match for 5108 is Yield. The Yield strategy's 6% gross-yield anchor is reachable on a meaningful share of older detached stock in Salisbury, and the rental criteria respond more positively than the macro signal would imply. The risk read is consistent with the rest of the northern Adelaide affordability belt. The SEIFA signal is doing real work, tenant-quality variance is wider than in higher-decile postcodes, and the realistic yield is lower than the headline.
Salisbury SA 5108 recorded strong house price growth of 20.15% over the 12 months to June 2026, with a current median house price of $787,000, according to yourinvestmentpropertymag.com.au and smartpropertyinvestment.com.au.

PropertyRanker scores any Australian property against 12 criteria across three pillars: Growth, Cashflow, and Risk. SEIFA is a primary signal for economic strength and a supporting one for entry-price risk. It also informs the crime side of hazard risk, though physical overlays like flood, bushfire and coastal exposure, and recorded crime data where available, take priority there. The decile of 1 shown above gives a listing in Salisbury a softer starting line on economic strength, though often a firmer one on entry-price risk, since less advantaged postcodes usually carry lower entry prices.
On top of that, PropertyRanker chooses one of four strategies (Balanced, Growth, Yield, Regional) and applies a per-strategy yield anchor. The anchors are 3.5% for Growth, 5% for Balanced, 6% for Yield, and 7% for Regional. A postcode at this level tends to make the Yield (6% anchor) and Regional (7% anchor) strategies more reachable, because a lower entry price lifts the gross yield a listing can achieve, while a Growth result usually depends on a specific catalyst such as an infrastructure or renewal pipeline.

SEIFA is a postcode-level read. The fastest sanity check on any single decile reading is to compare it against the suburbs that surround it.
Salisbury's postcode 5108 is large, and includes Salisbury itself, parts of Salisbury North, and adjacent residential pockets. A SEIFA decile cannot tell you which street, which build vintage, or which proximity to the train line a listing falls inside. The infrastructure pipeline in the Salisbury LGA has historically been uneven, with some pockets seeing significant uplift and others stalling. Recent council planning notices, the actual condition of the property, and the realistic rent-yield ratio against the suburb average all matter more than the macro signal. Score the listing in PropertyRanker for a verdict that accounts for these.
The data positions Salisbury as a high-risk, yield-oriented postcode rather than a broad-based investment prospect. A SEIFA IRSAD score of 842, sitting in the 4th state percentile within South Australia, drags PropertyRanker's economic_strength, hazard_risk, and entry_point_risk criteria materially. What partially offsets that signal is the suburb's rental_market_depth: Salisbury sits on the Gawler line as a designated high-frequency station, with services running approximately every 15 minutes on weekdays, which supports consistent rental absorption. Score a specific listing to see how those competing signals net out on that property.
The data points to the High Yield strategy, anchored around a 6 percent gross yield, as the closest match for this postcode. Older detached stock in Salisbury tends to carry lower entry prices relative to rent, which is the condition that makes a 6 percent yield anchor reachable on a meaningful share of listings. The Capital Growth and Balanced strategies both rely on stronger economic_strength and entry_point_risk scores than a decile 1 SEIFA reading can support, so those strategies score less favourably here without a specific listing's numbers to compensate.
The SEIFA signal is doing real work at decile 1: the raw score of 842 is well below the national mean of 1000, and that depresses three of PropertyRanker's twelve scoring criteria simultaneously. Tenant-quality variance is wider in lower-decile postcodes than in higher-decile ones, which affects how the rental_market_depth criterion is weighted in practice. The realistic yield on any given property is also likely to sit below the headline figure once vacancy periods and management costs are accounted for, so scoring the specific listing rather than relying on postcode-level tendencies is important.
Mawson Lakes, which is the adjacent suburb on the same Gawler line corridor and falls within the City of Salisbury LGA, is home to a university campus and associated education and technology precinct. That precinct generates a student and professional rental demand pool that spills into nearby affordable suburbs, including parts of Salisbury. PropertyRanker uses this as a supporting factor in the rental_market_depth criterion, partially countering the downward pressure from the decile 1 SEIFA reading. The weight that effect carries depends on the specific street and dwelling type, so it is a tendency to verify rather than a guarantee.
PropertyRanker runs twelve scoring criteria, of which three use the SEIFA IRSAD reading as a primary input: economic_strength, hazard_risk, and entry_point_risk, all of which are materially affected by the decile 1, 4th-state-percentile result for this postcode. The remaining criteria draw on listing-level data including the specific property's price and rent, as well as infrastructure and transport signals such as Salisbury's status as a high-frequency Gawler line station. Because the live yield and vacancy figures vary by individual listing, the score for any property in 5108 should be run directly rather than assumed from suburb-level tendencies.
