Same $150,000. Same ten years. Same assumed 6% growth. In an index fund, that money compounds to about $269,000. As the deposit on a $900,000 townhouse growing at the identical rate, it becomes roughly $717,000 in equity after holding costs. Property didn't grow faster; we assumed it couldn't.
The May 2026 federal budget rewrote the tax half of the property vs shares investment debate in Australia, and from 1 July 2027 the capital gains maths changes for both asset classes at once. What survives is the one advantage a share portfolio cannot copy: a lender will fund the bulk of a property purchase at home loan rates and wait 30 years to be repaid. No margin lender offers that on an ETF.
Timing sharpens the question. The RBA lifted the cash rate in February, March and May 2026 and held it at 4.35% in June, with the next decision due on Tuesday 11 August 2026. A rising-rate cycle thins the field: fewer bidders on auction day, more room to negotiate, and a market split clean in two. Cotality's June 2026 figures show Perth up 23.9% and Brisbane up 17.4% over the year while Sydney and Melbourne fall, with the national median at $937,722. Where you would buy now matters as much as whether you buy, and we unpack that in our two-speed market outlook.
One caveat before the numbers: the right mix for you depends on income, tax position and timeline, so your accountant and financial adviser belong in this conversation alongside your broker.
Property vs shares: what did the May 2026 budget change?
Three things, and each one moves the scales.
First, capital gains. From 1 July 2027 the 50% CGT discount is replaced by indexation of your cost base plus a 30% minimum tax rate, and the change applies to shares and property alike. In plain English: instead of halving your taxable gain after 12 months, you subtract the inflation component and pay tax, at no less than 30%, on the real gain. For a specialist at the top marginal rate, the old discount halved the gain no matter what inflation did; indexation shields only the inflation slice. Long-held assets with strong real growth get taxed harder. Both asset classes wear it equally, so on its own this change picks no winner.
Second, negative gearing. For established property bought after 12 May 2026, losses are quarantined from 1 July 2027: the annual shortfall stops offsetting your salary, but it stays deductible against your residential property income, including the eventual gain, and carries forward until it's used. New builds keep the full deduction against salary, and negative gearing on anything owned before 12 May 2026 is untouched. (New to the mechanics? Start with negative gearing explained in plain English.) That change is property-specific, and it lands hardest on the classic mum and dad play of buying an older house and claiming the losses.
Third, the quiet one. Super funds keep their CGT discount. Treasury closed the discount for individuals and left it standing inside super, which makes a share-heavy super fund one of the few places the old tax treatment still exists. If you already max your concessional contributions, nothing changes. If you don't, the budget just raised the price of ignoring them.
The upshot: the budget hit property's tax case harder than it hit shares, levelled the CGT field, and handed super an edge. If tax were the whole contest, shares inside super would now win it. It isn't the whole contest.
If tax no longer decides it, what does?
Leverage. You've been told property beats shares because of the tax breaks. That argument mostly died on 12 May 2026. Property's real edge was never the deduction: it's that a lender will hand you $810,000 at home loan rates, secured against the asset, with no right to force a sale while the repayments are met.
Try replicating that with shares. A margin loan gears you far less, costs more than a home loan, and carries the feature that ruins compounding: the margin call, a forced sale at the exact moment prices are down. Property is the only mainstream investment where the lender brings up to 95% of the money and none of the impatience.
| Property (lender-funded) | Shares (margin loan) | |
|---|---|---|
| Gearing available | Up to 95% LVR, no LMI, for doctors and dentists through Wity; 85% for any borrower | Materially lower, set per stock by the lender |
| Borrowing cost | Home loan rates | Priced above home loan rates |
| Forced-sale risk | None while repayments are met | Margin calls in a downturn |
| Entry and exit costs | Stamp duty in the tens of thousands; agent fees on sale | Brokerage in the tens of dollars |
| Liquidity | Weeks to months | Minutes |
| CGT from 1 Jul 2027 | Indexation + 30% minimum | Identical treatment |
Look at the bottom row, then the top one. The new CGT regime treats both assets the same, so the decision collapses upward into the lending rows. A specialist who can control $900,000 of asset with a 10% deposit is playing a different game to one drip-feeding $2,000 a month into an ETF, even at identical growth rates. Leverage multiplies the growth. The lender's patience is what makes the multiplication survivable.
Same specialist, same $150,000, three endings
Dr Carmen Silva is a staff specialist at a Brisbane public hospital on $310,000, with $150,000 saved and a ten-year horizon. Assume an illustrative 6.00% variable rate and 6% annual growth on both asset classes throughout (not a quoted offer; actual rates and returns vary, as at July 2026). The growth rates match on purpose, so the only variable left is structure.
Path A: shares. She puts the $150,000 into a broad index fund and reinvests distributions. At 6% compounding it reaches about $269,000 by year ten. Total transaction costs for the decade: under $200 in brokerage. Clean, liquid, no tenants.
Path B: property, new build. She buys a $900,000 new-build townhouse in Chermside, on Brisbane's northside. Under our medico policy she could put down 5%, but she chooses 10%: a $90,000 deposit plus roughly $35,000 in stamp duty and purchase costs, keeping $25,000 as an offset buffer. The $810,000 loan carries no LMI, where standard lending policy would typically add $12,000 to $18,000 at that LVR. By year ten the townhouse reaches about $1.61 million, leaving roughly $800,000 in equity. Holding it costs money along the way: rent of about $700 a week against interest and expenses leaves a shortfall near $18,000 a year early on, shrinking as rents rise. Because it's a new build the shortfall stays deductible against her salary, and the after-tax holding cost across the decade comes to roughly $85,000. Net position: about $717,000.
Path C: property, established. Same numbers, but an established house settled after 12 May 2026. From 1 July 2027 the shortfall is quarantined: it stops offsetting her salary year to year, though it stays deductible against her property income and carries forward to reduce the taxable gain when she eventually sells. The cash-flow difference is roughly $8,000 a year while she holds. Call it $72,000 across the decade, before the carried-forward losses claw some of it back at sale, for a net position near $645,000. Still comfortably ahead of the shares path, because leverage dominates, but the budget just made the new build about $72,000 cheaper to hold than its established twin. That gap did not exist before 12 May 2026. It's the rewritten maths.
On sale, the new CGT rules treat all three paths identically. Under the old regime she would have halved each taxable gain; gains accrued before 1 July 2027 still get the 50% discount, and for gains from that date on she indexes the cost base for inflation and pays at least 30% on the real gain, whichever asset she sells. The exact bill depends on inflation over the decade, which is the point of indexation. What the change doesn't do is reorder the paths.
Based on typical scenarios and illustrative assumptions. Individual outcomes vary.
Where do shares beat property?
Four places, and pretending otherwise helps nobody's decision.
Short horizons. Dr Silva's townhouse cost roughly $35,000 to enter and would cost around 2% in agent fees to exit. That round trip needs years of growth just to break even, so money you may need within about five years belongs in shares or cash, not bricks.
Diversification. One townhouse is one suburb, one asset, one tenant. Cotality's June 2026 data makes the concentration risk vivid: Perth rose 23.9% in the same year Melbourne fell. An index fund spreads you across hundreds of companies in a single trade.
Liquidity. You can sell $20,000 of an ETF before lunch. You cannot sell a bedroom.
The super wrapper. Concessional contributions are taxed at 15% instead of your marginal rate, and from 1 July 2027 super is the last structure keeping the CGT discount. For a high earner, share exposure inside super is now the most tax-favoured asset position in the country.
Follow that through and the real answer for most high-income professionals stops being either/or. It becomes a sequencing question: which asset first, and how does the first one fund the second?
How do high earners run both at once?
The common structure puts property at the core for leverage, shares around it for liquidity and diversification, and super as the tax wrapper. The property leg then does double duty. As it grows, equity released through refinancing can fund the share allocation, and a debt recycling strategy converts non-deductible home debt into deductible investment debt along the way.
Two lending realities shape the sequence. APRA's debt-to-income caps, live since 1 February 2026, limit how much new lending can sit at six times income or more, and a specialist holding two investment loans can reach that ceiling faster than she expects. New builds and construction lending are exempt, one more post-budget tilt towards new stock, and the order you buy in decides how far the portfolio runs; our guide to building a property portfolio covers the sequencing in detail.
Serviceability is where share investors get a surprise. Assessors typically shade rental income to about 80 cents in the dollar, but dividend income usually needs a multi-year history before it counts at all, so a portfolio that funds your lifestyle can add nothing to your borrowing power. The Wity Borrowing Power Assessment models your capacity across 45+ lenders before you commit to either asset, which is how a specialist finds her real ceiling rather than one bank's calculator's guess. And if the property leg comes first, our step-by-step first investment property guide walks the order of operations.
