McKinnon Sec or Bentleigh Sec — the catchment line is one street and runs your next 12 years.
This is the most aggressive school-zone premium in Melbourne’s south-east, and the line that creates it runs through the middle of streets, not between suburbs. McKinnon Secondary College’s catchment puts about $300K on a 3-bedroom house compared with the Bentleigh Secondary catchment three streets south (REA rolling 12-month sales to March 2026 — see property for the wider south-east trajectory). The catchment was tightened in 2018 and the schools enforce zoning hard — out-of-zone enrolments at McKinnon are essentially restricted to siblings of currently enrolled students. So the decision you make is not Bentleigh or McKinnon as suburbs; it’s which side of the catchment boundary your front door sits on.
I read the My School VCE data every year and I’ve spent the last four weeks pulling the comparable-sales detail block-by-block in the 3204 postcode and adjacent. I have also called both schools’ enrolment offices for current zone-status confirmations and talked to four parents with kids at McKinnon, Bentleigh and Tucker Road Bentleigh primaries. Below is what the line actually costs and what it actually buys.
The catchment line, in detail
McKinnon Secondary College’s catchment runs broadly between four arterials:
- North — Centre Road (the back of the McKinnon shops)
- South — North Road
- West — Wheatley Road / East Boundary Road
- East — Murrumbeena Road
That’s the broad outline. Inside it, the boundary slices mid-block on three named streets where the catchment-premium effect is sharpest:
Tucker Street, Bentleigh — the catchment line runs along the street, with the McKinnon-side numbers in-zone and the opposite-side numbers in the Bentleigh Secondary catchment. Identical 1950s weatherboards on the two sides have sold within $280K of each other in the last 12 months (REA, comparable 3BR sales). This is the single most-quoted example among inner-south-east real-estate agents.
Mavis Avenue, Bentleigh — splits roughly mid-block. North end is in-zone for McKinnon; south end is Bentleigh Secondary catchment.
Patterson Street — runs along the southern edge of the catchment, with the McKinnon-side carrying the premium.
The Department of Education’s Find My School tool (findmyschool.vic.gov.au) is the only reliable source for a specific address. The Department reviews the boundary in October each year for the following enrolment intake. Don’t sign a contract or a lease relying on a real-estate agent’s “in-zone” claim without confirming it on Find My School yourself, the same week — agents have been wrong on these mid-block boundary streets, and the cost of being wrong is the entire premium.
What the data actually says
McKinnon Secondary’s results are real, not a marketing artefact:
| Metric (2024) | McKinnon Secondary | Bentleigh Secondary | Victorian state-school average |
|---|---|---|---|
| VCE median study score | 33 | 30 | 28 |
| Study scores at 40+ | ~36% | ~14% | ~9% |
| Year 9 NAPLAN (reading) | Top decile | 2nd-top decile | Median |
| ICSEA (My School) | ~1130 | ~1085 | 1000 |
| Enrolment | ~2,200 | ~1,300 | n/a |
McKinnon’s VCE median of 33 with ~36% of scores at 40+ is competitive with the south-east private schools at one-thirtieth of the per-year fee. That outcome combined with no fees is what’s pricing the catchment.
But the comparison the property market makes — that McKinnon is “the good school” and Bentleigh Secondary is the consolation — overstates the gap. Bentleigh Secondary’s 2024 VCE median of 30 puts it well above the state government average. NAPLAN sits in the second-top decile. ICSEA is ~1085 against a Victorian average of 1000. The school has improved meaningfully since 2018 and the data does not support treating it as a fallback. The $300K premium is buying you the top-decile cohort and the 36%-at-40+ pipeline, not rescuing your kid from a poor school.
What you actually get for the $300K
Three things, in the order the parents I spoke to ranked them:
1. The cohort effect. McKinnon’s 2,200-student secondary draws a tightly self-selected catchment of families who moved specifically for the school. Half-an-hour of Year 9 maths in a McKinnon classroom is, in the words of one Year 11 mum I spoke to (32-year residence in the catchment, two kids through the school), “a different temperature room than the same lesson in a comparable suburb school.” The cohort is doing the work of teachers in many subjects.
2. The VCE pipeline. McKinnon runs a structured Year 10 academic-tracking system that filters into VCE subject selection. Enrolment officers will tell you the school does not “select” within the in-zone enrolment, and that’s true; what it does is run the in-zone cohort through tighter academic monitoring than most state secondaries. The 36%-at-40+ outcome is partly cohort and partly that tracking.
3. The in-zone scarcity guarantee. Once you’re inside the catchment, your kids’ enrolment is essentially confirmed. Out-of-zone applications across all year levels in 2026 ran into the high hundreds with admissions in the single digits. This scarcity is what makes the catchment property market behave like a private-school fee in capitalised form — a one-off house premium that pays “tuition” for both kids, in perpetuity.
What you save in the Bentleigh Secondary catchment
1. The $300K — and what it costs in fees over 12 years. Bentleigh Secondary charges a voluntary contribution around $700/year. Over six years of secondary for two kids, that’s $8,400 in fees against the McKinnon catchment’s house premium. Even if you index $300K at 4% real return over 12 years, you’re losing roughly $180K in opportunity cost on the premium versus $8,400 in fees. The state-school comparison favours the catchment premium for almost everyone; it doesn’t favour it as forcefully as the agents pitch.
2. House sizes and renovations. The Bentleigh Secondary catchment includes a deeper run of post-war brick veneer on slightly larger blocks than the bungalow stock dominating the McKinnon catchment. Median block size for sub-$2M sales runs about 90sqm larger in the Bentleigh Secondary catchment than the McKinnon equivalent (REA rolling 12-month). For families wanting a third bedroom, a study, or a back yard, this matters.
3. The Bentleigh shopping strip. Centre Road’s Bentleigh end has a deeper retail and food strip than McKinnon’s village. The Brewer Road weekend cafes, the Bentleigh-end Centre Road dining, the Frankston-line train access without the McKinnon-station catchment-shopping crowd at 8am.
Primary school overlap (don’t assume)
The most common error I see families make is assuming “in-zone for McKinnon Primary = in-zone for McKinnon Secondary.” The two zones overlap heavily but are not identical. Some streets are in McKinnon Primary’s catchment but in Bentleigh Secondary’s. Some are the reverse.
Likewise, Tucker Road Bentleigh Primary sits inside the Bentleigh Secondary catchment but the school’s results are strong (NAPLAN Year 5 in the second-top decile, 2024) — so the Bentleigh Secondary catchment is not a “primary school problem”; it’s mainly a secondary VCE-pipeline gap.
If you have one kid at primary age and one at secondary age, you have to check both zones independently for any address you’re considering. Find My School lets you query both at the same address in two clicks.
The renovation trap on boundary streets
Tucker Street, Mavis Avenue and Patterson Street have a specific property dynamic that real-estate agents are reluctant to spell out: the catchment line is not moved by renovation, demolition or subdivision. If you buy an out-of-zone house on the boundary cheap and renovate it, your kid is still out-of-zone the next year. There is no “rezoning” pathway for individual properties.
The Department reviews zones annually but the trend over the last decade has been for zones to tighten (the 2018 review removed several blocks from McKinnon’s western edge). Don’t bet on a zone expansion.
Who should pick which
Pick the McKinnon Secondary catchment if: state-school VCE outcomes are the explicit reason you’re moving; you have two or more kids likely to attend secondary in-zone; you can absorb the $300K premium without it pushing the rest of the family budget into stress; you don’t need a fourth bedroom.
Pick the Bentleigh Secondary catchment if: you can’t absorb the McKinnon premium without compromising on house size or renovation budget; your kids’ likely path is private secondary anyway (in which case the Bentleigh primary feeders are competent, the public-secondary catchment is irrelevant, and the Bentleigh strip is the better neighbourhood); you want larger block, deeper retail strip, or both.
Look outside both catchments if: you need a 3BR house under $1.5M (it doesn’t exist in either as of April 2026); you want to be near the Frankston line at McKinnon or Bentleigh stations but can’t afford either premium — Ormond, Carnegie and Glen Huntly catchments may give you proximity without the full McKinnon premium, with their own state-secondary catchments to investigate.
What I’d do
If both kids are state-secondary-bound and the budget works, the McKinnon Secondary catchment is rationally priced — the cohort effect and the 36%-at-40+ VCE pipeline are real, and capitalising “private-equivalent” outcomes into a one-off house premium makes more sense than paying private fees twice over. The premium is high but not irrational.
If the McKinnon premium would force a 4-bedroom house down to a 3-bedroom or block out a renovation budget, take the Bentleigh Secondary catchment, bank the difference, and use Tucker Road Bentleigh Primary into Bentleigh Secondary as the path. The 30-vs-33 VCE gap is real but it is not the difference between a state-school education and a private one.
What I would not do is buy on the boundary streets — Tucker, Mavis, Patterson — without confirming the address on Find My School the morning of the offer, and again the morning of contract exchange. The line moves through a kitchen, not a backyard fence, on more than a few of those properties.
For the inner-east equivalent of this catchment-line decision, see our Camberwell vs Canterbury schools comparison — same dynamic, different postcode.
What to ask at the school tour
The boundary-street risk means the standard tour question list isn’t enough. Ask:
- For McKinnon Secondary: when was the most recent enforcement audit on out-of-zone enrolment, and how does the school verify residency at Year 7 entry? (Verifies you’re not buying a premium for a kid who’ll be turned away.)
- For Bentleigh Secondary: which Year 9 NAPLAN cohort drove the 2024 second-top-decile result, and is that cohort still in the school?
- At both: what’s the median Year 12 ATAR for the median student, not the top-quartile? The 36%-at-40+ figure measures the top end; the median tells you about your kid.
- Boundary streets only: ask the school office to confirm the specific address on Find My School in front of you, the day of the tour. Don’t accept “we think you’re in zone.”
Bottom line
Pick the McKinnon Secondary catchment if: state-school VCE outcomes are the explicit reason you’re moving; both kids will be in-zone secondary; you can absorb the $300K premium without compromising the rest of the family budget.
Pick the Bentleigh Secondary catchment if: the McKinnon premium would push you down a bedroom or block out a renovation; secondary will be private regardless; or you want the deeper Centre Road retail strip and a larger block.
Look outside both catchments if: you need a 3BR under $1.5M (it doesn’t exist in either zone as of April 2026) — Ormond, Carnegie and Glen Huntly catchments offer Frankston-line proximity without the full McKinnon premium. Methodology and source notes on our methodology page.
