Maribyrnong (3032) sits roughly 8 kilometres north-west of the Melbourne CBD inside the City of Maribyrnong, one of the most densely populated local government areas in metropolitan Melbourne. Its SEIFA IRSAD score of 1063 places it in national decile 9 of 10 and at the 82nd state percentile within Victoria, firmly in the advantaged band and well above the national mean of 1000. That reading reflects a suburb that has undergone sustained gentrification as former industrial land along the river corridor has been converted to residential use. For investors, the score sets a useful macro frame, but it does not resolve the questions that determine whether a specific listing stacks up.
ABS 2021 IRSAD release. Score 1063 (national mean = 1000).
A SEIFA IRSAD score of 1063 tells PropertyRanker three things at the macro level. First, on economic_strength, the suburb's income and occupation profile sits comfortably above the national average, which tends to support tenant quality and reduce vacancy risk over the medium term. Second, on hazard_risk, higher-SEIFA inner-ring suburbs in Melbourne have historically attracted more consistent infrastructure investment and maintenance, though flood overlay along the Maribyrnong River is a genuine site-specific hazard that the postcode-level score cannot resolve. Third, on entry_point_risk, a decile 9 reading in an inner-west location typically correlates with pricing that already reflects strong demand, meaning the margin for error on acquisition cost is narrower than in lower-decile suburbs.
The suburb's demographic profile reinforces the SEIFA signal. The City of Maribyrnong has the second most ethnically diverse population in Victoria, and Maribyrnong itself has seen an influx of higher-income, more educated residents as industrial sites have been redeveloped. The median age skews young (mid-30s), which supports rental demand from professionals and students, including those connected to the Victoria University student village located within the suburb.
For strategy matching, the advantaged SEIFA band and inner-west location make Maribyrnong most naturally aligned with PropertyRanker's Capital Growth strategy, which anchors around a gross yield of approximately 3.5 percent. Investors targeting the Balanced strategy (around 5 percent gross yield) should verify whether current asking rents and prices in the specific segment (house versus unit) support that threshold before proceeding. High Yield and Regional strategies, which require 6 to 7 percent gross yields, are unlikely to be achievable at current inner-Melbourne pricing without accepting elevated entry-point risk, but scoring the specific listing will confirm this.
Maribyrnong's house market shows divergent readings across sources as of mid-2026: CoreLogic data via yourinvestmentpropertymag.com.au records a median house price of $1,208,000 with 5.04% annual growth over 88 sales, while propertyvalue.com.au (Cotality) reports a lower $1.1M median down 5.0% annually across 77 sales, reflecting the suburb's thin and volatile transaction base. Vendor discounting sits at -5.6% per propertyvalue.com.au, days on market for houses have lengthened to 48 days per Woodards, and Melbourne's broader vacancy rate tightened from 1.8% to 1.6% over the year per SQM Research data cited by openagent.com.au, pointing to a mixed or steady market temperature.

Melbourne vacancy tightened per SQM Research, but days on market for houses rose 20% year-on-year per Woodards and vendor discounting of -5.6% per Cotality signals sellers are conceding ground, producing a mixed steady reading 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 9 shown above gives a listing in Maribyrnong 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.
The SEIFA reading is one of twelve signals in PropertyRanker's model and operates entirely at the postcode level. It cannot see the following factors that materially affect a listing's score. First, flood and planning overlay status: the Maribyrnong River has a documented flood history and parts of the suburb carry overlay designations that affect insurability and future development rights. Second, SQM vacancy: the postcode-level vacancy trend matters, but the micro-level vacancy for the specific dwelling type (house versus apartment versus student accommodation) can diverge significantly from the suburb average. Third, body corporate health: for units and apartments, the financial position and deferred maintenance schedule of the owners corporation is invisible to any postcode model. Fourth, pricing against recent comparable sales: a decile 9 suburb does not guarantee a fairly priced listing. Score the specific listing in PropertyRanker to get a verdict that accounts for all of these factors alongside the SEIFA macro signal.
The SEIFA IRSAD score of 1063 (national decile 9) indicates an economically advantaged suburb with above-average income and occupation profiles, which PropertyRanker treats as a positive macro signal for economic_strength and tenant quality. However, a strong SEIFA reading does not make any individual listing a sound investment. Entry pricing in an inner-west suburb at this SEIFA level tends to be elevated, so the margin for error on acquisition cost is narrower than in lower-decile locations. Score the specific listing in PropertyRanker to see how all twelve criteria resolve for that address.
Maribyrnong's decile 9 SEIFA profile and inner-west Melbourne location align most naturally with PropertyRanker's Capital Growth strategy, which anchors around a gross yield of approximately 3.5 percent. Investors targeting the Balanced strategy (around 5 percent gross yield) should verify whether current rents and the specific asking price support that threshold. High Yield and Regional strategies, which require 6 to 7 percent gross yields, are generally difficult to achieve in inner-ring Melbourne at this SEIFA level without accepting significant entry-point risk.
Three risks stand out at the postcode level. The Maribyrnong River creates genuine flood overlay exposure for some properties, and this is a site-specific hazard that the SEIFA score cannot resolve. Entry-point risk is elevated because a decile 9 inner-west suburb tends to be priced for optimistic assumptions, leaving less buffer if conditions soften. For units and apartments, body corporate health and deferred maintenance are invisible to any postcode model and require direct due diligence. PropertyRanker's listing-level score incorporates flood and overlay status, SQM vacancy, and pricing against comparable sales to give a more complete risk picture.
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. Maribyrnong's score of 1063 (national decile 9, state percentile 82 within Victoria) contributes positively to economic_strength and moderates the hazard_risk signal at the macro level. The remaining nine criteria draw on listing-specific data including current SQM vacancy, flood and planning overlays, body corporate financials, and pricing against recent comparable sales, which the postcode-level SEIFA reading cannot see.
Maribyrnong shares postcode 3032 with Ascot Vale and sits adjacent to Avondale Heights (3034) to the west and Maidstone (3012) to the south-west. Maidstone sits within the same City of Maribyrnong LGA but generally carries a lower SEIFA profile, which may translate to different entry pricing and yield dynamics. Avondale Heights falls under the City of Moonee Valley and has its own SEIFA reading. Comparing SEIFA scores across these suburbs is a useful starting point, but each listing should be scored individually in PropertyRanker because micro-level vacancy, overlay status, and comparable sales can diverge significantly even within the same postcode.
