The gap between what a new apartment costs and what an older one sells for has stretched wider than most buyers realise. New two-bedroom apartments in Australia now sell for 30% more than equivalent older stock, and for three-bedroom units the premium hits 45%. That difference matters more than ever, with the national median dwelling value sitting at AUD 848,858 and rents forecast to climb another 25% by 2029. Whether you’re buying your first home or adding to a portfolio, the choice between old and new has real money attached to it.

Every capital city in Australia faces a housing supply shortfall. New apartment completions in Melbourne dropped 50% in FY2025, and across Sydney, Melbourne, and Brisbane the total pipeline sits roughly 45% below pre-pandemic rates. At the same time, immigration and returning international students keep demand high. That combination — less supply, steady demand — pushes new-build prices up and leaves older apartments looking cheap by comparison. The question is whether that discount is a genuine opportunity or a warning sign.
Here’s what you actually need to know.
The central concept to grasp here is replacement cost.
What I tend to notice is that most buyers default to “new is better” without running the numbers on what that premium actually buys them. In some cases the extra spend makes sense — better energy performance, lower maintenance, modern layouts. In others it’s mostly paying for marketing and higher builder margins. This article walks through the trade-offs so you can see where your money goes.
What You’ll Actually Pay: Price Premiums And Yield Reality
The headline numbers tell one story, but the real picture shows up when you compare what you spend versus what you earn back. Across the four largest apartment markets, the gap between purchase price and rental return tells you which side of the old-new line offers better cash flow.

| City | Median unit price | Weekly rent | Gross yield | Vacancy rate |
|---|---|---|---|---|
| Sydney | AUD 855,468 | AUD 704 | 4.3% | 1.5% |
| Melbourne | AUD 605,221 | AUD 575 | 4.9% | 1.8% |
| Brisbane | AUD 688,559 | AUD 604 | 4.5% | 0.9% |
| Gold Coast | AUD 820,000 | AUD 824 | 5.2% | 1.3% |
A few things stand out. Melbourne offers the lowest entry price by a clear margin — nearly AUD 250,000 less than Sydney — yet delivers a yield half a point higher. Gold Coast rents are high enough to push the yield above 5%, even with a median price above AUD 800,000. Brisbane’s vacancy rate of 0.9% is the tightest in the country, meaning few empty weeks between tenants. Those figures all come from established units, not new builds. New apartments in the same suburbs typically sell for 16–45% more but rent for similar amounts, which pulls their effective yield down.
That premium matters even more when you consider what else you pay. Stamp duty, strata fees, and mortgage costs all scale with purchase price. A new one-bedder in悉尼 costing AUD 500,000 attracts roughly AUD 15,000 in stamp duty in NSW. An older unit at AUD 430,000 (reflecting the 16% discount) brings that figure closer to AUD 11,000. The difference goes straight to your deposit or your offset account.
Three Mistakes Buyers Make With Old And New Apartments
The research exposes some clear patterns in where buyers misjudge the market. Here are the three that cost the most.
Paying the new-build premium for features that don’t hold value
Developers add amenities like rooftop gardens, gyms, and security lobbies to justify higher prices. CBRE research confirms those features drive the premium. The problem is that buyers often pay for them upfront but the ongoing strata fees hit immediately. A new apartment with a concierge and pool might carry quarterly levies of AUD 2,000–3,000. Older buildings without those extras might charge half that. Over five years the difference can reach AUD 20,000 or more — money that comes out of your yield before you see a cent. If you never use the gym or the pool, you’re paying for someone else’s amenity.
Ignoring replacement cost when comparing prices
Most buyers compare new and old apartments by looking at the sticker price. The smarter comparison is replacement cost — what it would actually cost to build the older apartment today. In many Australian suburbs, established units sell 20–40% below replacement cost because construction inflation has outpaced resale values. That means the older apartment is effectively “on sale” compared to the real cost of creating equivalent living space. A two-bedroom older unit priced at AUD 550,000 might cost AUD 700,000+ to build new. The discount exists because the market hasn’t fully adjusted to rising build costs. That gap tends to close over time as supply stays tight and new prices keep climbing.
Overlooking the supply pipeline in your city
Each capital has a different construction outlook. Brisbane faces a projected shortfall of 7,000+ apartments through 2029, with build costs almost 50% higher than Melbourne and industry capacity already maxed out. Sydney is only expected to hit 21% of its apartment supply target by 2029. Melbourne’s completions dropped 50% in FY2025, but its forecast supply of 7,770 apartments per year through 2029 is the highest of any city. Buying new in a city with a deep supply deficit might protect your capital growth. Buying new where supply is relatively healthier means the premium is harder to recover. Checking your local pipeline before you commit is worth the time.

How To Evaluate An Apartment: Old Vs New
Once you know the numbers, the decision comes down to matching the property type to your situation. Here’s how I’d weigh the options in practice.
When older apartments make sense
If your priority is cash flow and entry price, established units win on yield in every major city. The lower purchase price means smaller mortgage, lower stamp duty, and usually lower strata fees. What you give up is modern finishes, better energy ratings, and sometimes the first few years of tax depreciation benefits. The older building also carries a higher risk of major repairs — new roof, lift replacement, waterproofing — so a building inspection before exchange is non-negotiable. Focus on well-located, family-friendly apartments in low-rise blocks rather than high-rise towers, which tend to have higher vacancy risk and more volatile strata outcomes.
When new apartments make sense
A new build suits buyers who plan to hold long-term and can absorb the lower initial yield. The depreciation schedule on a new apartment (typically AUD 10,000–15,000 per year in the first five years) can offset taxable income for investors. New buildings also come with warranty protections for structural defects — typically 6–10 years depending on the state — and lower immediate maintenance costs. If you’re buying off-plan, the risk is that the completed apartment values the premium you paid against a market that may have shifted. The new construction purchase risks are worth reading through before you sign.
What the supply pipeline means for your choice
This is the forward-looking angle that changes the maths. With new-build prices forecast to rise 23% by 2026, buying new today means paying today’s premium and hoping tomorrow’s market validates it. Buying established means locking in a price below replacement cost now, with the expectation that rising new-build prices will eventually pull older values up behind them. That dynamic works best in cities with the most severe supply constraints — Brisbane and Sydney rank highest here. In Melbourne, where the supply pipeline is larger, the catch-up effect may take longer. The high-rise vs low-rise comparison adds another layer worth factoring into your decision.

Why Supply Constraints Favour Established Apartments
The structural shortage of new apartments across Australia’s capitals isn’t a short-term blip. Labour shortages, planning bottlenecks, and build costs that remain elevated mean the supply pipeline will stay below demand for years. That supports prices across the board — but the biggest gains tend to flow to assets bought below replacement cost. Established apartments already sit at that discount. If new-build prices rise 23% by 2026 as forecast, the floor under older apartment values lifts too. Buyers who focus on location, building quality, and yield — rather than age — are the ones who capture that uplift.
