Sunbury (3429) sits approximately 38 kilometres north-west of Melbourne CBD inside the City of Hume, occupying an unusual position as a large, self-contained township that straddles the boundary between metropolitan Melbourne and the Macedon Ranges fringe. Its SEIFA IRSAD score of 1000 places it precisely at the national mean, in decile 7 of 10 nationally and at the 57th percentile within Victoria, a reading that PropertyRanker classifies as advantaged. That result reflects a suburb that is neither a pocket of concentrated disadvantage nor a high-income enclave, but a broad, mixed-demographic community with household incomes and service access sitting modestly above the Victorian midpoint.
ABS 2021 IRSAD release. Score 1000 (national mean = 1000).
A SEIFA score at the national mean carries real analytical weight for investors. On PropertyRanker's twelve-signal model, SEIFA feeds directly into three criteria: economic_strength, hazard_risk, and entry_point_risk. A decile 7 reading supports a neutral-to-positive read on economic_strength, suggesting the local income and occupation base is unlikely to create structural downward pressure on rents or values over a full cycle. It does not, however, signal the kind of high-income concentration that tends to anchor premium capital growth suburbs. Sunbury's 57th-percentile position within Victoria is consistent with its character: a large outer-ring town with a growing family demographic, a median household income around $100,000 per year, and a housing stock that ranges from established township homes to newer master-planned estates. The suburb's rail connection to the CBD (electrified, Zone 2) and its proximity to Melbourne Airport employment are structural positives that sit outside the SEIFA frame but matter for demand. Strategy alignment is worth considering carefully here. At a median house price around $675,000 (June quarter 2025), gross yields at typical Sunbury rents are unlikely to satisfy a High Yield or Regional strategy anchor of 6 to 7 percent. The suburb's profile fits more naturally against a Capital Growth or Balanced strategy, where the yield anchor sits closer to 3.5 to 5 percent and the thesis rests on population-driven demand and infrastructure access rather than income return alone. Investors targeting yield above 5.5 percent should stress-test current asking rents carefully before committing.
Sunbury VIC 3429 recorded a median house price of $715,000 over the 12 months to April 2026, representing annual capital growth of approximately 7.0%, according to CoreLogic data published via yourinvestmentpropertymag.com.au and corroborated by Woodards and Image Property. There were around 932 to 993 house sales over the same period, with average days on market of just 16 to 18 days, indicating strong buyer demand. Propertyvalue.com.au reports an average vendor discount of -3.5%, while htag.com.au notes tight stock on market (0.31%) and low inventory of 2.1 months, and melbz.com.au reports a vacancy rate of 1.7%, all pointing to a supply-constrained market with sustained price momentum.
Vacancy is tight at 1.7%, days on market have shortened materially year-on-year to 16-18 days, and vendor discounts of -3.5% alongside 7% price growth indicate vendors are holding firm, placing the market in a warming band.

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 7 shown above gives a listing in Sunbury 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 signal. It cannot see the specific street, the estate, the build year, the strata, or the orientation of a given lot. Within Sunbury's 3429 boundary, quality and price vary materially between the established township core, the newer growth estates on the southern and eastern fringes, and the semi-rural pockets near the creek corridors. Before drawing a conclusion on any specific listing, investors should check current SQM vacancy data for 3429 (outer-ring suburbs can shift quickly as new stock is released), confirm body corporate health and sinking fund status for any unit or townhouse, review flood and planning overlay status given Sunbury's creek and low-lying areas, and price the listing against recent comparable sales rather than the suburb median alone. Run the specific listing through PropertyRanker to receive a verdict that accounts for all twelve signals, including the factors a postcode-level SEIFA reading cannot reach.
Sunbury's SEIFA IRSAD score of 1000 places it precisely at the national mean, in decile 7 of 10 nationally and at the 57th percentile within Victoria, which PropertyRanker classifies as advantaged. That reading supports a neutral-to-positive signal on economic_strength, meaning the local income and occupation base is unlikely to create structural downward pressure on rents or values over a full cycle. The suburb is not a high-income enclave, but a broad, mixed-demographic community with household incomes and service access sitting modestly above the Victorian midpoint. Score a specific listing on PropertyRanker to see how those signals interact with the property's individual characteristics.
Sunbury's profile fits most naturally against a Capital Growth or Balanced strategy, where the gross-yield anchor sits closer to 3.5 to 5 percent and the investment thesis rests on population-driven demand and infrastructure access rather than income return alone. The suburb's electrified rail connection to the CBD (Zone 2 on the Sunbury line, with peak-hour services and High Capacity Metro Trains following the Sunbury Line Upgrade) and proximity to Melbourne Airport employment are structural demand positives that support those strategies. Investors targeting a High Yield or Regional strategy anchor of 6 to 7 percent should stress-test current asking rents carefully against the suburb's typical price range before proceeding. Run a listing through PropertyRanker to see the live yield gap against each strategy anchor.
The most material risks to check are yield compression and flood exposure. At median house prices around the $675,000 range (June quarter 2025), gross yields at typical Sunbury rents are unlikely to satisfy a high-yield strategy, so entry-point discipline matters. On the hazard side, the Victoria SES and City of Hume identify Sunbury as a location at risk of flooding, with Jacksons Creek capable of flooding under prolonged rainfall events; individual lots near that waterway carry meaningfully higher hazard_risk scores on PropertyRanker's model. Investors should check the specific property's flood overlay through Melbourne Water and the City of Hume before forming a view.
PropertyRanker feeds the SEIFA IRSAD reading into three of its twelve scoring criteria: economic_strength, hazard_risk, and entry_point_risk. For Sunbury, the decile 7 reading produces a neutral-to-positive economic_strength signal, reflecting a community with incomes and service access above the Victorian midpoint but without the high-income concentration associated with premium growth suburbs. The score interacts differently across the four strategies, so two identical SEIFA readings can produce different overall scores depending on which strategy a listing is assessed against. Score the specific address on PropertyRanker to see how those three SEIFA-driven criteria combine with the remaining nine signals for that property.
Sunbury sits inside the City of Hume but occupies an unusual position as a largely self-contained township on the fringe of the Macedon Ranges, distinct in character from Hume's inner suburban areas such as Craigieburn or Broadmeadows. That geographic distinction matters because flood exposure, infrastructure access, and demographic mix vary considerably across the LGA; Sunbury's own SEIFA reading at the 57th Victorian percentile is meaningfully higher than some other Hume postcodes. PropertyRanker scores at the suburb and listing level rather than at the LGA level, so Sunbury's individual signals are not diluted by the broader council area's data. Always score the specific address to capture the relevant local context rather than relying on LGA-level averages.
