It is the argument that has launched a thousand barbecue debates across Australia: should you put your money into the sharemarket or into property? Everyone has an opinion. Your uncle swears by his Vanguard ETF. Your mate from work just bought a third investment property in Brisbane. But what does thirty years of actual data say?
We went deep into the numbers -- pulling from CoreLogic, the Russell Investments/ASX Long Term Investing Report, Vanguard's Index Chart, and S&P Dow Jones Indices -- to give you the most honest breakdown we can. No shilling for either side. Just data.
The Raw Scoreboard: 10, 20, and 30-Year Returns
Let us start with the headline numbers. According to Canstar's analysis of ASX data, Australian shares have returned approximately 9.8% per annum over 30 years, including dividends. Listed property securities returned a comparable 9.3% per annum over the same period. Meanwhile, CoreLogic data shows national residential dwelling values grew at roughly 6.8% per annum over 30 years in pure capital growth terms.
At first glance, shares win comfortably. But that comparison is deeply misleading, and here is why.
The share figure includes reinvested dividends. The property figure is capital growth only -- it excludes rental income entirely. When you add gross rental yields of 3-5% per annum on top of that capital growth, residential property's total return starts looking much closer to 9-11% per annum depending on the period and location.
Over the most recent decade, the picture shifts further. CoreLogic data shows capital city median house prices rose roughly 70% over ten years to mid-2023, while the S&P/ASX 200 price index rose just 46% over the same period. The 2018 Russell Investments/ASX Long Term Investing Report confirmed this trend: over the ten years to December 2017, residential property returned 8% per annum while Australian shares returned just 4%, weighed down by GFC losses.
The Leverage Elephant in the Room
Here is where the comparison gets genuinely unfair -- in property's favour. Australian banks will happily lend you 80% (sometimes 90%) of a property's value at competitive home loan rates. Try getting 80% leverage on shares through a margin loan and you will find higher interest rates, lower LVR caps (typically 50-70%), and the ever-present terror of margin calls.
Consider this scenario: you have $100,000 in savings. With shares, you invest $100,000. With property, you put down a 20% deposit and buy a $500,000 asset. If both assets grow at 7% per annum:
- Shares: Your $100,000 becomes $196,715 after 10 years
- Property: Your $500,000 asset becomes $983,576 -- a gain of $483,576 on your $100,000 deposit (minus interest costs)
Even after accounting for mortgage interest, the leveraged property return on your actual capital deployed is dramatically higher. Analysis from Property Planning Australia found that over 30 years, the leverage advantage can create a difference of over $4 million on the same starting capital. That is not a rounding error.
Income Streams: Dividends vs Rent
Australian shares offer something genuinely world-class: franking credits. Because companies pay 30% tax before distributing dividends, investors receive a tax credit for that amount. For someone in a lower tax bracket or a self-managed super fund paying 15% tax, franked dividends are extraordinarily tax-efficient.
According to S&P Global data, the S&P/ASX 200 Franking Credit Adjusted Total Return Index delivered approximately 7.2% per annum over ten years for tax-exempt investors, compared to 5.6% without the franking credit adjustment. That is a meaningful boost.
Rental yields, on the other hand, have been compressed in recent years. Gross yields in Sydney and Melbourne often sit at 2.5-3.5%, though regional areas and Brisbane have pushed higher. The advantage of rent, however, is that it tends to rise with inflation and you can increase it annually -- something a dividend-paying company might cut entirely during a downturn.
Tax Treatment: Negative Gearing and CGT
Australia's tax system is unusually generous to property investors. Negative gearing allows you to deduct investment property losses (including mortgage interest) against your salary income. As Treasury.gov.au notes, this applies to any investment, but property investors use it most aggressively because of the larger loan sizes involved.
Both asset classes benefit from the 50% capital gains tax discount for assets held longer than 12 months. But property investors can also claim depreciation on the building and fixtures, creating paper losses that reduce taxable income without any actual cash outlay. Shares simply do not offer an equivalent.
Volatility: The Sleep-at-Night Factor
This is where shares take a serious hit. During the GFC, the ASX All Ordinaries fell approximately 54% from peak to trough between October 2007 and March 2009. Balanced super funds lost 13-18% in a single year. Many retail investors panic-sold at the bottom and never recovered their losses.
Australian property? It rose 7.5% in 2008. Yes, rose. While the world's financial system was melting down, Australian house prices barely flinched. Even during the 2017-2019 correction and the brief COVID dip, national dwelling values never fell more than about 8% peak-to-trough before rebounding strongly.
The best investment is the one you can actually hold through the bad times. Property's lower volatility means more investors actually capture the long-term returns, rather than selling in a panic at the worst possible moment.
The Costs Nobody Talks About
Property advocates often gloss over the friction costs. Stamp duty alone runs 3-4% of the purchase price in most states. Add conveyancing, building inspections, and selling agent commissions (typically 2-2.5%), and you are paying 6-8% in round-trip transaction costs. Then there are ongoing costs: council rates, insurance, maintenance, property management fees, and vacancy periods.
Shares? A brokerage fee of $5-30 per trade. An ETF management fee of 0.04-0.20% per annum. No maintenance calls at 2am about a leaking hot water system. The cost advantage for shares is enormous and compounds significantly over decades.
According to analysis by Morgans, when you properly account for all hidden costs of property ownership, the net return gap between shares and property narrows considerably -- and in some periods, shares actually come out ahead.
So Who Actually Wins?
The honest answer: it depends on how you invest, not just what you invest in.
On a pure, unleveraged, like-for-like total return basis over 20-30 years, Australian shares and residential property have delivered remarkably similar results -- somewhere in the range of 8-11% per annum including income. Shares have a slight edge in raw total returns and dramatically lower costs. Property has a massive edge in accessible leverage and lower volatility.
The real-world winner for most Australians has been property, but not because it is inherently a better asset class. It wins because leverage amplifies returns, because forced mortgage repayments create disciplined saving, and because people do not panic-sell their house when the market dips 10%.
The smartest investors, of course, own both. A diversified portfolio with leveraged property and a growing share portfolio (ideally through tax-advantaged super) gives you the best of both worlds: leverage-amplified capital growth from bricks and mortar, plus liquidity, diversification, and franking credits from equities.
Whatever you choose, the worst decision is doing nothing. Both asset classes have crushed cash and bonds over every meaningful long-term period. The important thing is to start.
