In some cases, old imperial standards were replaced with rounded metric values, as with horse racing or the size of beer glasses (rounded to the nearest 5 cm 3).

The Australian Bureau of Statistics Act 1975 and Census and Statistics Act 1905 authorise the ABS to collect, store, and share anonymised data.
