Each year, the kangaroo imagery on the Kangaroo Gold Bullion series of coins changes, which explains its popularity with both collectors and gold investors alike.  

For 2018, the obverse of the 1/10 oz gold Kangaroo features a stylised design of two Kangaroos bounding across an Australian rural landscape. The imagery is inscribed by the words 'AUSTRALIAN KANGAROO', and the coin's year '2018', weight '0.1 oz', and purity '9999 GOLD' .

The reverse of the Gold Kangaroo coin features a head portrait of the official head of state of Australia, Queen Elizabeth II, and the coin's official face value of '15 dollars'. Gold Kangaroo bullion coins are non-circulating legal tender in Australia and are issued under the Australian Currency Act of 1965

The Australian Kangaroo gold bullion coin series was first issued in 1990, but is officially called the 'Australian Nugget Kangaroo Gold Bullion Series' since from 1987 to 1989 a similar coin with imagery of famous Australian gold nuggets was issued.
