Wolli Creek (postcode 2205) sits in the inner south of Sydney, roughly 10 kilometres from the CBD, within the Bayside Council local government area. The suburb records a SEIFA IRSAD score of 1068, placing it in national decile 9 of 10 and at the 77th state percentile within New South Wales. That reading classifies the area as advantaged, sitting well above the national mean of 1000. For investors using PropertyRanker, this SEIFA band feeds directly into three of the model's twelve scoring criteria: economic strength, hazard risk, and entry point risk.
ABS 2021 IRSAD release. Score 1068 (national mean = 1000).
Wolli Creek is a purpose-built high-density suburb, formally established only in 2002 after a rezoning of what had been a predominantly industrial precinct. The suburb is defined almost entirely by apartment towers, and the stock profile is therefore narrow: investors here are almost always evaluating strata titles rather than freestanding houses. The SEIFA decile 9 reading reflects a resident base that skews toward higher incomes and lower relative disadvantage, consistent with the suburb's appeal to professionals who value the T4 and T8 train interchange, which connects directly to the CBD in roughly 13 minutes and to Sydney Airport in around 5 minutes.
A strong SEIFA score does not, by itself, make any individual listing a sound investment. Within a postcode that is almost entirely apartments, the gap between a well-managed building and a poorly managed one can be substantial. Body corporate health, sinking fund adequacy, and strata levy trajectory are variables that a postcode-level socioeconomic index cannot see. The same applies to flood and inundation risk: Wolli Creek sits beside two waterways, the Wolli Creek waterway and the Cooks River, and individual lots vary in their overlay exposure depending on elevation and position within the suburb.
On strategy fit, the suburb's inner-city location and high land cost base tend to compress gross yields toward the lower end of the spectrum. Investors targeting PropertyRanker's Capital Growth strategy (anchored around 3.5 percent gross yield) are more likely to find alignment here than those running a High Yield or Regional strategy. A Balanced strategy match is possible but depends heavily on the specific purchase price and achievable rent for the individual unit, which requires scoring at the listing level rather than the postcode level.
Wolli Creek (2205) is an almost exclusively unit-dominated suburb, with houses representing fewer than 2% of transactions. According to yourinvestmentpropertymag.com.au (to June 2026), the unit median sits at $819,000, up 3.08% over 12 months, on 335 unit sales. Domain.com.au and lsre.com.au corroborate the 2-bedroom unit median at $845,000 with average days on market of 38 days, while the vacancy rate is reported near 1.9% by multiple sources, pointing to a tight rental market.

Vacancy is low and stable near 1.9%, days on market for units is short at 38 days (well below state norms), and units are transacting at or above list price, indicating two of three signals favour a warming market.

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 9 shown above gives a listing in Wolli Creek a stronger starting line on economic strength than the national median postcode, and a softer one on entry-price risk, since more advantaged postcodes usually carry higher 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 of relative advantage tends to suit the Growth (3.5% anchor) and Balanced (5% anchor) strategies more readily than Yield (6%) or Regional (7%), because a higher entry price compresses the gross yield a listing can reach without a specific value-add.
Read the scoring guide for the full criteria list and how the verdict thresholds work.
Before drawing any conclusion from the SEIFA decile 9 reading, investors should confirm several things at the listing level. First, check the strata records: request the last two years of AGM minutes, the current sinking fund balance, and any outstanding special levies. Second, review the flood and overland flow overlay for the specific lot, given the suburb's position beside two waterways. Third, compare the asking price against recent comparable sales within the same building or nearby buildings of similar age and configuration, not just the broader postcode. Fourth, check the current SQM vacancy rate for 2205, because a high-density suburb with ongoing construction can see vacancy shift materially in a short period. The SEIFA reading tells you about the socioeconomic character of the area; it cannot tell you whether this specific unit is priced correctly or whether the building is financially healthy. Score the specific listing in PropertyRanker to get a verdict that accounts for current vacancy, body corporate health, flood and overlay status, and pricing against recent comparable sales.
The SEIFA IRSAD score of 1068 (national decile 9) indicates an advantaged socioeconomic profile, which is a positive macro signal for economic strength and tenant demand. However, Wolli Creek is almost entirely high-density apartments, so investment outcomes depend heavily on building-specific factors such as strata health, levy trajectory, and vacancy in the immediate complex. PropertyRanker uses SEIFA as one of twelve scoring criteria, and the remaining signals require a listing-level assessment to produce a meaningful verdict.
The suburb's inner-city location and high land cost base tend to align most naturally with PropertyRanker's Capital Growth strategy, which is anchored around a 3.5 percent gross yield. Investors targeting the High Yield strategy (around 6 percent) or the Regional strategy (around 7 percent) are unlikely to find those yield anchors met at current price levels in this postcode, though the exact figure depends on the specific unit and purchase price. A Balanced strategy match at around 5 percent is possible but should be verified by scoring the individual listing rather than relying on postcode-level assumptions.
The suburb's primary risk factors for investors are concentrated in the strata environment: a large volume of apartment stock means body corporate quality varies significantly between buildings, and poorly managed sinking funds can create unexpected special levy exposure. The suburb also borders two waterways, the Wolli Creek waterway and the Cooks River, so individual lots should be checked against flood and overland flow overlays before committing. Ongoing or recently completed construction in the precinct can also affect vacancy rates, which investors should verify at the current SQM level rather than relying on historical averages.
PropertyRanker uses the SEIFA IRSAD score of 1068 (decile 9, 77th state percentile in NSW) as a primary input for three of its twelve criteria: economic strength, hazard risk, and entry point risk. A decile 9 reading is a positive macro signal, suggesting the surrounding area has relatively high socioeconomic resources and lower relative disadvantage compared to most Australian suburbs. It does not, however, account for the specific street, the build year, the strata condition, or the orientation of the unit, all of which are captured only when you score the individual listing inside the tool.
Wolli Creek's immediate neighbours include Arncliffe and Turrella to the south and west (both sharing postcode 2205), Tempe to the north (2044), and Earlwood to the northwest (2206). Arncliffe and Earlwood offer a mix of freestanding houses and older units that may suit different strategy profiles, while Turrella is a quieter, lower-density residential area. Investors comparing these suburbs should score each relevant listing separately in PropertyRanker, because SEIFA and other macro signals can differ between postcodes even across short distances, and the asset class differences between apartment-dominant Wolli Creek and the house-dominant neighbouring suburbs are material to yield and growth expectations.
