The 2023 1/10oz Australian Koala Platinum Bullion Coin combines a compact fractional format with one of The Perth Mint's most recognisable Australian wildlife themes. Struck from 1/10 troy ounce of 99.95% pure platinum, the coin offers a smaller-format way to own physical platinum while retaining the annual artistry of the Australian Koala series.
The 2023 reverse captures a touching moment between a koala and its young, portraying an adult climbing a eucalyptus tree with a dependent joey clinging to its back. With a maximum mintage of just 15,000 coins, the release combines precious metal content with an annually changing Australian design.
The obverse carries the special Queen Elizabeth II Memorial Obverse, featuring Jody Clark's effigy accompanied by the dates of Her Majesty's reign, 1952–2022. Issued as Australian legal tender with a denomination of $15 AUD, each coin is supplied in a protective acrylic capsule.
The reverse portrays an adult koala climbing a tree with a dependent joey clinging securely to its back, capturing the close bond between mother and young high among the branches of its natural habitat.
Designed by Ing Ing Jong, the reverse also incorporates the inscription KOALA, The Perth Mint's traditional P mintmark, the 2023 year-date, and the coin's 1/10oz 9995 PLATINUM weight and purity declaration.
The obverse features Jody Clark's effigy of Queen Elizabeth II together with the dates 1952–2022. Known as the Queen Elizabeth II Memorial Obverse, the design was used on selected Australian coins following the Queen's death in September 2022 and before the transition to the King Charles III effigy.

The 2023 release combines an annually changing Koala design with the Queen Elizabeth II Memorial Obverse. Featuring the dates 1952–2022, the obverse places the coin within the short transitional period between Australian coinage featuring Queen Elizabeth II and the introduction of the King Charles III effigy.
The 1/10oz fractional size provides a smaller unit of physical platinum than a full one-ounce coin. It combines 0.100 troy ounce of .9995 platinum with the convenience of a compact, individually encapsulated Australian legal tender coin.
One of the distinguishing features of the Australian Koala series is its changing annual artwork. Rather than repeating the same koala image each year, The Perth Mint creates new interpretations of the animal and its Australian habitat, giving individual dates their own identity.
The Perth Mint set a maximum mintage of 15,000 coins for the 2023 1/10oz Platinum Koala, placing a defined limit on the number that could be released.
