What $100 in 1981 was worth — measured in gold

The price of gold didn't get more expensive. The value of the Australian dollar fell.

93.1%

of the Australian dollar's value, gone — measured in gold, since 1981.
It now takes 14.4× more dollars to buy the same ounce.

In 1981, $100 bought 0.25 oz of gold at $400/oz. Held as metal, that same money is worth $1,440 at today's gold price of $5,761/oz (spot as of 2026-08-02).

Same $100. Three rulers.

Measure	$100 from 1981, today	Multiple
Official story — AU CPI (ABS via FRED)	$488	4.9×
Money created — M3 broad money	$4,217	42.2×
In gold — honest weight, valued today	$1,440	14.4×

The gap between 4.9× (CPI) and 42.2× (M3) is official inflation understating the money actually created. The gap between 42.2× and 14.4× (gold) is the flight to hard money — gold outrunning even the printing.

1981 in the fiat story

The Australian series begins where Bretton Woods ends. Through the seventies the AUD was pegged and managed while Australian CPI ran to double digits — the debasement was administered rather than traded.
