When did the farthing cease as legal tender in Australia?

Answer 1

With the possible exception of traders tokens (with the traders business name on them), there were no "Australian" Farthings ever produced.

The only Farthings to ever circulate in Australia were British Farthings.

Answer 2

The British One Shilling coin was last minted for circulation in 1966. After decimalisation in 1971, the Shilling became the equivalent of a 5 Pence coin and co-circulated with the Shilling until it was officially demonetised in 1991.

Answer 3

The last Farthing was minted in 1956, but they continued to be used until 1960 when they had become virtually worthless, and were demonetised on the 31st of December, 1960.

Answer 4

The British Farthing was last minted in 1956 and ceased to be legal tender in 1960.
