Gold Ounce (1 oz), Australian Koala, Coin Type from Australia (issued 2017 - )
Coin TypeGold Ounce (1 oz), Australian Koala

The Australian one ounce gold piece (abbreviated as 1 oz and designated with Au for "gold") is a bullion coin format. Uniquely, in Australia there are two mints independently authorised to strike legal tender: the Royal Australian Mint (which also makes the country's circulating coinage) and the Perth Mint which only makes collector and bullion coins, as well as other bullion products.

Both mints issue coins featuring the koala - one of the most famous and distinctive animals native to Australia; the reverse design change every year. The gold one-ounce coins have a face value of 100 dollars, but this is only symbolic - as the bullion value of their precious metal content is much higher. The overall weight is slightly more than one ounce, so that the pure gold content is exactly 1.000 AGW (one troy ounce Absolute Gold Weight).
