It’s not just one generation — and understanding the collision is the key to buying smarter in 2026.
Every few months, a new headline emerges blaming millennials, or investors, or Baby Boomers for making housing unaffordable. The truth? Today’s property prices are being shaped by several forces colliding at once — and if you’re buying, selling or investing right now, knowing who’s in the room with you changes everything.
Here’s what’s actually driving buying patterns and pricing in the Australian market right now.
Who’s Really Driving Today’s Property Prices?
1. The 40-Something Wave
Social demographer Bernard Salt has identified what he calls the single biggest demographic force set to reshape Australian housing this decade: millennials moving into their 40s.
Right now, there are 3.6 million Australians in the “40-something” bracket. By 2036, that number grows to 4.2 million — a 16% increase. This isn’t a small shift. It’s a tidal wave of buyers entering the exact life stage where Australians traditionally make their biggest property moves.
The early 40s is the stage where couples decide the apartment isn’t cutting it anymore. They want space. A backyard. A good school catchment. A commute that doesn’t punish them. And increasingly, many are tapping the Bank of Mum and Dad — using family equity or gifted deposits to bridge the affordability gap and land the home they need, not just the one they can afford on paper.
The biggest concentrations of this cohort growth will be felt in Melbourne (+131,000), Sydney (+114,000) and Brisbane (+57,000) — so if you’re buying in middle-ring suburbs or established family corridors in any of those cities, you’re competing directly with this wave.
2. Investors: The Quiet Bidding Power in the Room
While first-home buyers and upgraders get most of the media attention, investors are quietly outmuscling them at the finance level.
According to ABS data analysed by Cotality, investors now account for 39.7% of all new housing loans nationally — the highest share in nine years. In the December quarter alone, investors borrowed $43 billion.
Compare that to first-home buyers, who accounted for just 17.8% of loans ($19.3 billion), with an average loan size of around $607,000. The average investment loan? Around $716,000.
That gap in borrowing capacity means investors are regularly outbidding first-home buyers and even some upgraders on the same properties — particularly well-located townhouses, established homes near transport, and high-yield corridors in growth areas.
The result: rents and prices are moving together in the same corridors, squeezing buyers at both ends of the decision.
3. Prestige and Lifestyle Buyers Resetting the Anchor
There’s a third force that doesn’t get enough attention: the prestige and lifestyle buyer — equity-rich downsizers, returning expats and high-income professionals who are resetting price expectations in key pockets, particularly in Queensland and NSW.
Prestige apartment sales have nearly tripled over the past decade, with Queensland now holding 43% of national prestige sales and NSW at 41%. Victoria, which once dominated this segment, has dropped to just 16%.
Why does this matter for “ordinary” buyers? Because when a prestige property transacts at a new record price in a suburb, it recalibrates what agents, vendors and appraisers expect for every other property nearby. The ripple effect on mid-market pricing is real and sustained.
4. Supply Still Can’t Keep Up
All of this demand is hitting a market where new supply remains constrained. Labour shortages, construction cost inflation (running at 4–5% in key markets), and planning delays in NSW and Victoria are limiting how quickly new housing can respond.
This matters because when listings are thin and demand has multiple competing groups bidning — upgrading millennials, active investors, prestige buyers — even modest pressure creates outsized price moves. Vendors know the competition is real, so discounting is rare and clearance rates stay supported.
What This Means If You’re Buying or Investing Right Now
Understanding who’s in the market with you helps you plan, not panic.
-
If you’re an upgrader in your late 30s or 40s, you’re not alone — but that also means competition for quality family homes will remain fierce. Having your finance structured correctly before you start inspecting is non-negotiable.
-
If you’re an investor, the lending data shows the window for strong borrowing capacity is open — but lender policy, buffers and structure matter more than ever when rates and serviceability are scrutinised.
-
If you’re a first-home buyer, the challenge is real, but there are still products, structures and government schemes that can level the playing field when used strategically.
The market isn’t broken — it’s competitive. And the buyers who win are the ones who show up prepared.
