Still Picking Suburbs by Distance to the CBD? You're a Decade Behind.

If you're still filtering investment properties by "must be within 20km of Melbourne CBD," I have bad news. You're using a framework that belongs in the previous century.

The idea that property values radiate outward from the CBD in neat concentric rings — with the best growth closest to the centre — was a reasonable heuristic fifty years ago. Melbourne was a monocentric city. Most white-collar jobs were downtown. The tram network defined the premium suburbs. If you worked in an office, you lived within train distance of the city.

That model is broken. And the data proves it.

According to RMIT research, only 49.5% of Melbourne's working population commutes to the CBD. That means more than half of all workers never go to the city centre for their job. And of those who do commute to the CBD, only 12.5% go five days per week 1. The rest are hybrid — two or three days in the office, the remainder from home.

So we have a city where the majority of workers neither work in the CBD nor commute there daily. Yet most property investors are still obsessed with proximity to a place their tenants rarely visit.

Something doesn't add up. Let me show you what actually drives suburban property demand.

Melbourne is a polycentric city now

Melbourne hasn't functioned as a single-centre city for at least a decade. It operates as a network of satellite commercial hubs, each with its own employment base, retail infrastructure, and residential catchment.

The southeast alone has three major satellite centres. Dandenong is a massive employment hub — home to one of Australia's largest industrial precincts, a major hospital, a TAFE campus, and a retail centre serving 500,000+ residents. Glen Waverley functions as the commercial and educational heart of Melbourne's eastern middle ring. And Frankston is a rapidly growing regional centre with a $1.1 billion hospital redevelopment creating 1,500+ permanent jobs 2.

In the west, Werribee and Sunshine function as independent economic centres. In the north, Broadmeadows and Epping serve similar roles.

The workers in these satellite centres — nurses, warehouse operators, tradespeople, teachers, retail managers — live locally. They drive to work. They shop at the local Westfield. They send their kids to local schools. A significant portion haven't been to Melbourne CBD in months, possibly longer.

For these households, the idea of "proximity to the city" is meaningless. What matters is proximity to their workplace, their kids' school, their GP, and their Coles. The property that serves those needs best is in the suburbs surrounding the satellite centre — not on a train line to Flinders Street 3.

This is why suburbs 30-40 kilometres from the CBD — suburbs that old-school investors dismiss as "too far out" — are delivering 7-8% annual capital growth while some inner-ring suburbs languish at 3-4%. The demand is local. The drivers are local. And the locals couldn't care less about the CBD.

The ripple effect: price pressure moves outward from activity centres

There's a well-documented phenomenon in Australian property called the ripple effect. When a suburb becomes unaffordable, demand spills into adjacent, cheaper suburbs. Those suburbs appreciate. Then demand spills further out. The wave radiates from the centre of activity.

But here's what most commentators get wrong: the centre of the ripple isn't the CBD. It's the local activity centre.

Glen Waverley is a perfect example. As Glen Waverley's median house price climbed past $1.5 million, families who couldn't afford it started looking at Wheelers Hill, Mount Waverley, and Mulgrave. Those suburbs appreciated. Then demand pushed further to Rowville, Noble Park, and Springvale South.

The ripple didn't start at the CBD and move outward. It started at Glen Waverley and moved outward. The CBD was irrelevant to the price dynamics.

We see the same pattern around Dandenong. As Dandenong's commercial centre grew and gentrification projects progressed, surrounding suburbs — Doveton, Hallam, Narre Warren — captured the spillover demand. Cranbourne and Hampton Park, another ring further out, are now in the acceleration phase of this ripple 4.

When I'm analysing suburb growth potential, I don't measure distance from the CBD. I measure distance from the nearest satellite centre and assess whether the ripple effect has reached the suburb yet. If a suburb is one to two rings outside a rapidly growing satellite centre, with affordable entry prices and high owner-occupier ratios, it's typically in the sweet spot for the next wave of capital growth.

Case study: how satellite demand drives our investment decisions

Let me show you how we apply this framework in practice.

When we assess a suburb for our clients, we don't measure distance from the CBD. We measure distance from the nearest satellite commercial centre and assess the suburb's position in the ripple effect.

Take Hampton Park. It sits approximately 42 kilometres from Melbourne's CBD. By the old framework, it's "too far out" — a suburb that traditional investors would dismiss without a second thought.

But Hampton Park is just 12 kilometres from Dandenong — a satellite centre with a major hospital, TAFE campus, industrial precinct employing 40,000+ people, and one of Australia's largest suburban shopping centres. The workers at Dandenong's factories, warehouses, and health facilities need housing. They can't afford Berwick or Narre Warren North. They can afford Hampton Park.

That local demand — driven by proximity to the Dandenong employment hub, not proximity to Melbourne CBD — is what creates the supply-demand imbalance. Hampton Park has added over 30,000 residents in the past fifteen years while dwelling construction has lagged by thousands. Owner-occupier rates sit above 70%. Vacancy is below 1.5%. These families aren't commuting to the CBD. They're driving ten minutes to the warehouse, the hospital, or the school.

We purchased a property at 15 Wren Street, Hampton Park for $590,000. After renovation, it rents for $850 per week. The bank valued it at $670,000 within four weeks. That $80,000 valuation uplift wasn't driven by proximity to Flinders Street Station. It was driven by proximity to Dandenong's employment centre and the chronic undersupply of family housing in the surrounding suburbs.

Contrast this with a property 15 kilometres from the CBD — say, in Northcote or Thornbury. Purchase price: $1.2 million. Rent: $650 per week. Yield: 2.8%. Capital growth: 4-5% per year. The CBD proximity commanded a price premium that the rental income can't support.

The Hampton Park property cost half as much, yields twice the rent, and is growing faster. Because it's positioned near the right centre — the satellite centre where the local workforce lives and works.

Owner-occupier demand: the stability factor

Satellite city suburbs tend to have higher owner-occupier ratios than inner-city suburbs. In our target corridors, owner-occupier rates range from 65% to 75% — meaning seven out of ten households own their home 5.

These families aren't speculating. They bought because they work locally, their kids attend local schools, and they've put down roots. They're not checking Domain every weekend to see if they could sell for a profit. They're mowing the lawn, painting the fence, and planning the next school holiday.

This creates extraordinary price stability. During market downturns, owner-occupiers hold. They don't sell. Turnover remains low — in some of our suburbs, fewer than 2% of houses change hands in any given year. That scarcity of supply, combined with steady inbound demand from population growth, creates a natural price floor.

Inner-city suburbs, by contrast, tend to have higher investor concentrations. When sentiment turns negative, investors sell. Multiple listings hit the market simultaneously. Prices adjust downward. The very proximity to the CBD that attracted investors becomes a vulnerability — because the suburb's price is set by sentiment, not by the number of families who need a home near their workplace.

I'd rather own a house in a suburb where 70% of residents plan to stay for a decade than a unit in a suburb where 60% of owners are investors who might sell next quarter. The long-term returns aren't even close.

The days of "buy close to the city" are over. Buy close to where people work, shop, and raise families. That's where the real demand lives — and it's 30-40 kilometres from Flinders Street.

The train station myth and what actually matters for tenants

While I'm busting myths, let me address another persistent one: "you need to be near a train station."

In inner Melbourne, yes — proximity to rail is a genuine value driver because many inner-suburb residents commute by train. But in the outer suburbs, the reality is different.

Our tenants in Melbourne's far southeast drive to work. Almost universally. The local employment centres — Dandenong's industrial precinct, the Cranbourne town centre, the Fountain Gate retail hub — are accessed by car, not by train. The train takes 70 minutes to reach the CBD. Driving to the local warehouse takes 12 minutes.

When we survey our tenants about what they value in a rental property, train station proximity doesn't crack the top five. What matters is: number of bedrooms, parking spaces, proximity to schools, proximity to their specific workplace, and weekly rent. A property with four bedrooms, two car spaces, and a ten-minute drive to Dandenong will rent faster and for more money than a three-bedroom house next to a train station that's 70 minutes from a workplace nobody commutes to.

This is counterintuitive for investors who grew up thinking rail proximity equals premium. And in Toorak, it's true. In Cranbourne, it's irrelevant. The tenants have told us so.

So when you're evaluating investment suburbs, stop measuring distance from the CBD. Stop obsessing over train stations. Start asking: where do the local workers actually work? How far is this property from the nearest major employer? What's the owner-occupier rate? And how constrained is the supply relative to the demand created by that local employment base?

Those questions will lead you to suburbs that the CBD-centric crowd dismisses — and those suburbs are exactly where the returns are hiding.

The data behind the myth: growth by distance band

Let me give you the actual numbers that disprove the CBD proximity theory.

Over the past decade, Melbourne's property growth by distance from the CBD tells a striking story. Properties within 10 kilometres of the CBD grew at approximately 4.5-5.5% per year. Properties between 10-20 kilometres grew at 5-6.5%. Properties between 20-35 kilometres — the middle ring, including suburbs like Glen Waverley and Box Hill — grew at 4-6%. And properties between 35-50 kilometres — the outer ring, including our core targets of Cranbourne, Hampton Park, and Narre Warren — grew at 6-8% per year.

Read that again. The outer ring outperformed the inner ring. The suburbs furthest from the CBD delivered the highest growth rates.

How is that possible if CBD proximity drives value?

Because the growth drivers in the outer ring are different — and stronger. Population growth in Casey-Cardinia has been running at 3%+ per year, triple the rate of inner-city LGAs. Dwelling construction has lagged population growth by thousands of homes. Owner-occupier rates are 15-20 percentage points higher than inner-city equivalents, creating price floors that inner-city suburbs lack.

And the affordability factor amplifies the effect. A suburb with a $650,000 median and growing incomes has room to appreciate. A suburb with a $1.5 million median and the same income base is stretched. Growth requires headroom, and the outer suburbs have more of it.

The next time someone tells you that properties close to the CBD are inherently better investments, ask them to pull the decade-long growth data by distance band. The numbers will surprise them. They surprised me when I first ran them. They shouldn't have — the logic is straightforward — but decades of CBD-centric marketing had created a cognitive bias that even data analysts needed to consciously override.

How we apply this to client strategy

When a new client comes to us and says "I want to invest close to the city," I don't argue. I ask questions.

"Why do you want to be close to the city?" The answer is almost always one of two things: they believe it's safer (less risk of price decline), or they believe tenants prefer it.

On the first point, I show them the downturn data. Inner-city apartment values dropped 12-18% during the 2018-2019 correction. Our outer southeast suburbs dropped 5-8%. The "safe" inner ring was actually the riskiest holding during the downturn, because investor-dominated suburbs don't have the owner-occupier price floor.

On the second point, I show them our vacancy data. Our far southeast properties — 35-45 kilometres from the CBD — have vacancy rates of 1.2%. Inner-city apartments have vacancy rates of 4-5%. The tenants aren't preferring inner-city locations. They're going where the value is. A family that can rent a four-bedroom house with a yard in Cranbourne for $500 per week isn't choosing a two-bedroom apartment in South Yarra for $550.

Usually, by this point, the client is reconsidering their assumption. Then I show them the numbers: Hampton Park at $590,000, renovated, renting $850 per week, bank valued at $670,000 four weeks after purchase. That case study converts more minds than any theoretical argument.

The CBD proximity bias is deeply ingrained. It takes data, not debate, to dislodge it. And once it's dislodged, the investment outcomes improve dramatically.
