The Australian five-cent coin was the third-smallest denomination coin of the decimal Australian dollar introduced in 1966. Since the demonetisation of the one and two cent coins in 1992 it has been the lowest-denomination coin in the country.

The coin was introduced into circulation on 14 February 1966. In its first year of minting, 30 million were struck at the British Royal Mint (then in London) in addition to 45.4 million at the Royal Australian Mint in Canberra. Since then, the coin has been produced exclusively at Canberra, apart from in 1981. In that year, 50.3 million were produced at the Royal Mint's new headquarters in Llantrisant, Wales; as well as 50 million from the Royal Canadian Mint in Winnipeg in addition to 62 million from Canberra .

The reverse side depicts an Echidna and the obverse side the head of state, Queen Elizabeth II.

There are no commemorative coins for this denomination. This coin has the highest mintage of any current coins and doesn't circulate well because of its value, like the one-euro cent. The lowest minted year is 1972 with 8.25 million coins and the highest was 2006 with 306.5 million , and the average today is 80 million coins per year. No coins were issued in 1985-86 with the former valued at $30 uncirculated.
