This chart shows a calculation of buying power equivalence for $1 in 1971 (price index tracking began in 1922).

For example, if you started with $1, you would need to end with $0.65 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $0.65 over time, that means that the "real value" of a single Australian dollar decreases over time. In other words, a dollar will pay for fewer items at the store.

This effect explains how inflation erodes the value of a dollar over time. By calculating the value in 1971 dollars, the chart below shows how $1 is worth less over 4 years.

According to the Bureau of Statistics, each of these AUD amounts below is equal in terms of what it could buy at the time:
