Seddon (3011) sits approximately 6 to 7 kilometres west of the Melbourne CBD inside the City of Maribyrnong, flanked by Footscray to the north and Yarraville to the south. Its SEIFA IRSAD score of 1048 places it in decile 8 of 10 nationally and at the 77th percentile within Victoria, firmly in the advantaged band and well above the national mean of 1000. That reading reflects a suburb that has moved decisively away from its working-class industrial origins through sustained gentrification over the past two decades. For PropertyRanker, this score feeds directly into three of the twelve scoring criteria: economic_strength, hazard_risk, and entry_point_risk.
ABS 2021 IRSAD release. Score 1048 (national mean = 1000).
A SEIFA IRSAD score of 1048 signals a resident base with above-average incomes, high rates of professional employment, and relatively low concentrations of economic disadvantage. Census data confirms that over 40 percent of Seddon workers are in professional services and close to 20 percent are in managerial roles, which underpins rental demand from a tenant cohort that tends to be stable and income-secure. The suburb is predominantly detached and semi-detached housing, with Victorian and Edwardian workers cottages making up the bulk of the stock. Larger blocks above 400 square metres are rare, which constrains supply and supports price floors but also limits development upside for investors seeking subdivision or dual-occupancy plays. Heritage overlays apply to parts of the suburb, so any renovation or redevelopment strategy requires planning advice before committing. The gross yield profile for houses has historically tracked below 4 percent, which aligns most naturally with PropertyRanker's Capital Growth strategy anchor of around 3.5 percent rather than the Balanced or High Yield strategies. Units have shown higher yields in the low-to-mid 4 percent range, which edges toward the Balanced strategy anchor of around 5 percent, though individual listings vary. The suburb's small geographic footprint, tight vacancy conditions historically, and proximity to the CBD are structural positives on the macro side of the model. However, SEIFA is a postcode-level signal and cannot see the specific street, the build year, the strata health, or the orientation of a given property. A strong SEIFA reading does not make every listing in 3011 a sound investment, and a weaker listing inside this postcode can still score poorly once PropertyRanker applies its full twelve-signal framework.
Seddon VIC 3011 recorded a median house sale price of approximately $1,075,000, $1,100,000 in the 12 months to mid-2026, representing flat to marginally negative annual growth (0.0% to -2.0%), according to CoreLogic data via yourinvestmentpropertymag.com.au and propertyvalue.com.au. Sales volume rose strongly, with Woodards reporting 109 house sales, up 23.9% year-on-year, while days on market for houses fell 12.5% to 49 days, suggesting improving buyer activity despite soft price growth. Vendor discounting of -4.7% and a vacancy rate near 1.15% point to a market that is broadly steady with some buyer leverage remaining.

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 8 shown above gives a listing in Seddon 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.
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.
Before drawing any conclusion from the SEIFA reading alone, investors should confirm several things at the listing level. First, check flood and overlay status: parts of the Maribyrnong corridor carry inundation risk, and individual lots in 3011 can sit inside or outside affected zones. Second, review heritage overlay conditions if any renovation or extension is planned, as Seddon has protected streetscapes that can restrict works. Third, obtain current SQM vacancy data for the postcode rather than relying on historical tightness; vacancy can shift with new supply from neighbouring Footscray. Fourth, for any unit or apartment, assess body corporate financials and the sinking fund balance, since older converted stock in this suburb can carry deferred maintenance. Fifth, price the listing against recent comparable sales in the same street type and configuration, not suburb-wide medians, because the spread between a renovated cottage and an unrenovated one in Seddon is material. Score the specific listing in PropertyRanker to get a verdict that accounts for all of this, including live SQM vacancy, flood and overlay status, and pricing against recent comparable sales.
Seddon's SEIFA IRSAD score of 1048 (decile 8 of 10 nationally, 77th percentile in Victoria) signals an advantaged economic base with a high share of professional residents, which supports stable rental demand and price resilience at the macro level. That said, a strong SEIFA reading is one of twelve signals in PropertyRanker's model and cannot determine whether a specific listing is well-priced, structurally sound, or free of overlay constraints. Investors should score the individual property rather than treating the suburb's SEIFA band as a blanket endorsement.
The gross yield profile for houses in Seddon has historically tracked below 4 percent, which aligns most closely with PropertyRanker's Capital Growth strategy anchor of around 3.5 percent. Units have shown yields in the low-to-mid 4 percent range, which edges toward the Balanced strategy anchor of around 5 percent, but individual listings vary and the live figure should be confirmed by scoring the specific property. The High Yield strategy (around 6 percent) and Regional strategy (around 7 percent) are unlikely to be achievable in this postcode based on the suburb's price and rent profile.
The primary risks to verify at the listing level are flood and inundation overlay exposure (parts of the Maribyrnong corridor carry this risk and individual lots differ), heritage overlay restrictions that can limit renovation or extension scope, and the limited supply of larger blocks that constrains subdivision strategies. Entry prices in an advantaged, gentrified inner suburb also compress gross yields, so investors targeting income rather than capital growth may find the numbers difficult to stack without a specific unit or dual-income configuration. Body corporate health is a further risk for any strata title in the postcode.
PropertyRanker uses the SEIFA IRSAD reading as a primary input for three of its twelve scoring criteria: economic_strength, hazard_risk, and entry_point_risk. Seddon's score of 1048 (decile 8, advantaged band) contributes positively to all three criteria at the postcode level. The remaining nine criteria draw on listing-specific data that SEIFA cannot see, including current SQM vacancy, body corporate health, flood and overlay status, build year, and pricing against recent comparable sales, so the final score for any given property can differ substantially from what the postcode-level SEIFA reading alone would suggest.
All three suburbs sit within the City of Maribyrnong and share broadly similar inner-west positioning, but they differ in price point, density, and development activity. Footscray (3011) carries higher commercial density and more active apartment development, which can affect vacancy and yield dynamics. Yarraville (3013) is often benchmarked alongside Seddon for its comparable village character and gentrification trajectory. West Footscray (3012) generally offers a lower entry price within the same LGA, which may suit investors prioritising yield over capital growth positioning. Each suburb should be scored separately in PropertyRanker, as SEIFA and other signals can differ at the postcode level.
