St Kilda East (postcode 3183) sits roughly 6 kilometres south-east of the Melbourne CBD, straddling the Cities of Glen Eira and Port Phillip in Melbourne's inner south. Its SEIFA IRSAD score of 1103 places it in the 10th national decile and at the 93rd percentile within Victoria, meaning the suburb ranks among the most socioeconomically advantaged areas in the country. That reading reflects a resident base with high household incomes, strong educational attainment, and low rates of economic disadvantage. For investors using PropertyRanker, this score feeds directly into the economic_strength, hazard_risk, and entry_point_risk criteria on the macro side of the model.
ABS 2021 IRSAD release. Score 1103 (national mean = 1000).
A SEIFA decile of 10 signals a structurally sound demand base. Residents in this bracket tend to sustain rental demand through economic cycles, and the suburb's dense, walkable character, anchored by Carlisle Street retail, Alma Park, and Balaclava Station on the Sandringham line, reinforces that stability. The housing stock is genuinely mixed: Victorian and Edwardian terraces sit alongside art deco flats, 1960s walk-ups, and newer strata developments. That diversity matters for investors because the macro SEIFA score applies equally to a renovated freestanding house and a one-bedroom flat in a large complex, even though those two assets carry very different risk and yield profiles.
The suburb's inner-city positioning and high-income demographic mean gross yields typically compress toward the Capital Growth strategy anchor (around 3.5 percent) rather than the High Yield or Regional bands. Investors chasing 6 percent or above will generally find the numbers difficult to reconcile with current entry prices here, unless a specific listing has an unusual configuration or a below-market rent. A Balanced strategy (around 5 percent gross) is possible in some segments, particularly older-style flats, but requires careful verification against recent comparable sales and current asking rents.
It is important to be clear about what SEIFA cannot see. The score is a postcode-level aggregate. It says nothing about a specific building's body corporate reserves, the flood or overlay status of a particular lot, the vacancy rate on a given street, or whether a listed price is fair relative to recent sales. A listing inside this postcode can score well or poorly on PropertyRanker's full twelve-criteria model depending on those asset-level factors.
St Kilda East houses recorded a median sale price of $1,670,000 with annual capital growth of 1.21% over the 12 months to April 2026, according to CoreLogic data published by yourinvestmentpropertymag.com.au, while propertyvalue.com.au (Cotality/RP Data) reported a softer read of $1.6M and -7.78% annual change, reflecting differing methodologies and periods. Woodards (PropTrack, to February 2026) recorded 91 house sales, down 9.9% year-on-year, with average days on market rising to 43 days, and propertyvalue.com.au reported an average vendor discount of -2.6%. HtAG Analytics characterised the suburb as supply-constrained but demand-softening, with a vacancy rate of 1.71% and stock on market of just 0.3%.
Days on market are rising year-on-year and vendor discounts remain present amid softening price reads across multiple sources, while vacancy holds stable at 1.71%, pointing to a cool market overall.

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 10 shown above gives a listing in St Kilda East 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 investment conclusion from the SEIFA reading, investors should confirm several things at the listing level. First, check the current SQM Research vacancy rate for postcode 3183; inner suburbs can tighten or soften faster than the macro signal suggests. Second, obtain the owners corporation (body corporate) records for any strata title, paying particular attention to the capital works fund balance and any outstanding special levies. Third, review the planning and overlay certificate for the specific lot, including flood zone, heritage overlay, and any development restrictions that could affect future value or rental use. Fourth, price the listing against at least three recent comparable sales within the same postcode and property type, not just suburb-wide medians, which can be skewed by the mix of houses and flats. The SEIFA score of 1103 is a genuine positive signal on the macro side of the PropertyRanker model, but it is one of twelve criteria. Score the specific listing in PropertyRanker to get a verdict that accounts for what this postcode-level reading cannot see.
A SEIFA IRSAD score of 1103, placing postcode 3183 in the 10th national decile and at the 93rd percentile within Victoria, signals a structurally sound demand base with high household incomes and low rates of economic disadvantage. That reading strengthens three of PropertyRanker's macro criteria (economic_strength, hazard_risk, and entry_point_risk), which is a meaningful starting advantage. However, the macro score applies equally to a renovated freestanding terrace and a one-bedroom flat in a large 1960s block, even though those assets carry very different yield and risk profiles. Whether a specific listing here suits an investor depends on what the full twelve-criteria model returns for that asset, not the suburb score alone.
The suburb's inner-city location and high-income demographic tend to compress gross yields toward the Capital Growth strategy anchor of around 3.5 percent, which is the most consistent fit for postcode 3183 at the macro level. A Balanced strategy (around 5 percent gross) is possible in some segments, particularly older-style flats, but requires careful verification against recent comparable sales and current asking rents. Investors targeting the High Yield (around 6 percent) or Regional (around 7 percent) bands will generally find those figures difficult to reconcile with typical entry prices in this postcode, unless a specific listing has an unusual configuration or a below-market rent. Score the individual listing on PropertyRanker to see which strategy band the live numbers actually support.
Flood exposure is a material, lot-specific risk in this area: the City of Port Phillip identifies St Kilda and Balaclava among its higher-risk areas, and the VICSES Local Flood Guide for Balaclava and St Kilda notes that the Shakespeare Grove Drain catchment, which covers parts of St Kilda East, carries flash-flood exposure with no formal retarding basins or levees in place. Beyond hazard risk, the suburb's mixed housing stock means strata-specific risks, including body corporate reserves and building condition, vary sharply between a heritage terrace and a large walk-up flat complex. Entry point risk is also real here: high demand from owner-occupiers in a decile-10 suburb can push listing prices above investment-grade levels, so verifying a listed price against recent comparable sales is essential before drawing any conclusion.
Postcode 3183 straddles the City of Glen Eira and the City of Port Phillip, and planning overlays, flood mapping, and local infrastructure investment can differ across that boundary. PropertyRanker's macro SEIFA signal is applied at the postcode level and does not split by council, so the economic_strength, hazard_risk, and entry_point_risk scores are consistent across the postcode. However, asset-level criteria such as overlay status and zoning need to be confirmed against the relevant council's planning scheme for the specific lot, because a property on the Port Phillip side sits under different planning rules than one administered by Glen Eira.
On the macro side, the SEIFA IRSAD score of 1103 (decile 10 nationally, 93rd percentile in Victoria) feeds directly into the economic_strength, hazard_risk, and entry_point_risk criteria. The remaining criteria in PropertyRanker's twelve-factor model draw on asset-level inputs: the specific listing price relative to recent comparable sales, current asking or achieved rents, proximity to infrastructure such as the Sandringham line (Balaclava Station is the nearest rail connection for much of the postcode), and planning overlay information. Because yields, vacancy, and comparable sales figures change frequently, PropertyRanker calculates those from live data at the time you score a listing rather than relying on static suburb-level averages.
