The Gold Ruler · an Antipodean Affairs investigation
An open, auditable comparison of the three things that went vertical in Australia after the September 1999 capital-gains tax discount — the money supply, house prices, and the price of gold — each re-stated in two units: Australian dollars, and ounces of gold. Every figure is sourced and every assumption is published, so the comparison can be audited, disputed, or replicated.
Pick your ruler. Measured in dollars, the housing boom looks unstoppable. Measured in gold — money that can’t be printed — much of it dissolves. The aim is not to argue that gold is the “true” measure of value, but to make one pattern visible.
House prices rose almost exactly in line with the money supply. In dollars they sextupled. Against gold, they roughly halved.
Before you can read any price, you have to know what’s happening to the thing prices are measured in. Australia’s broad money — currency, deposits and near-money in the banking system — sat at about A$526 billion at the end of 1999. By April 2026 the Reserve Bank put it at A$3,461 billion.
That’s a 6.6× increase in the supply of money chasing a roughly fixed supply of well-located land. Note the two near-vertical legs: the 2007–08 credit run-up, and the 2020–22 pandemic surge, when broad money jumped by over a third in three years.
Why this matters: if money grows ~6.6× while the population and housing stock grow modestly, scarce assets should climb steeply in dollar terms before any “bubble” explanation is needed.
Median house prices across the eight capital cities, tracking the trajectory each market actually took: Sydney’s early-2000s boom, the long Perth and Darwin mining plateau, the Brisbane–Adelaide–Perth “catch-up” of the 2020s, and the post-COVID surge that pushed six of the eight capitals past a million dollars.
Use the chips to isolate a city. The shapes differ wildly — but the destination is the same: a national median house near A$1.26 million, up from around A$200,000 in 2000.
Flip the ruler at the top to redraw this chart in ounces of gold, and watch what happens to the slope.
Gold isn’t productive and pays no yield — which is exactly why it works as a measuring stick. Its supply grows ~1–2% a year, roughly with the population, so its price in any currency is largely a readout of how fast that currency is being created.
In Australian dollars, gold has gone from about A$430/oz in 1999 to roughly A$6,100/oz in mid-2026 — about 14×, outrunning both the money supply and house prices. The 2019–2026 leg is near-parabolic.
Divide each capital’s median house by the gold price and the chart changes character. Instead of climbing forever, houses-in-gold peaked around 2003–04, again around 2017, and have fallen since — because gold has been the faster horse.
The national median house cost roughly 420 ounces of gold in 2000. Today it’s about 207 ounces. In hard-money terms, Australian housing is down about half since the turn of the century — even as the dollar price sextupled.
The dollar price of a house tells you what the money did. The gold price of a house tells you what the house did.
The Gold Ruler is a project of Antipodean Affairs, an independent editorial outfit that works with the Australian public record — the budgets, registers and price data that describe how the country is actually run.
Our starting point is that the unit you measure in is itself an editorial choice. A house price quoted only in dollars quietly assumes the dollar is a fixed yardstick — and it isn’t. Re-stating the same prices in something whose supply can’t be expanded by policy, gold, is not a claim that gold is money; it is a way to separate what an asset did from what the currency did. Measuring is not a verdict; it is a starting point for an honest argument.
Every number on this page is drawn from public data — the Reserve Bank, the ABS, the LBMA gold price and the standard national house-price series — and every rule we use to convert, derive or interpolate a figure is published in the methodology below. If you find an error in the data, a flaw in an assumption, or a more defensible series, we want to hear about it. The methodology is versioned so corrections are visible.
Antipodean Affairs has no affiliation with any political party, the Reserve Bank or the Treasury, or any bullion dealer, fund manager or financial institution. Nothing on this page is financial advice.
Work of this kind is only as credible as its sources and the assumptions that join them together. We publish ours in full so readers can audit, dispute, or replicate them. Where a series is measured directly we say so; where it is derived or interpolated, we say that too.
Three Australian series since 1999 — broad money, capital-city median house prices, and the gold price — each shown in Australian dollars and, via the ruler switch, in ounces of gold. Australian houses are then re-priced in gold, to separate what the houses did from what the money did.
v1.0 — Initial publication. Three Australian series — broad money, capital-city median house prices, and gold — with a dollars/gold ruler switch, and Australian houses re-priced in gold.
