The obverse of 2025 Australian Silver Kangaroos comes with a bust of His Majesty King Charles III. The King’s portrait was developed for the Perth Mint by Dan Thorne and shows His Majesty in left-profile relief. This first-generation effigy of Charles III depicts the monarch without a crown on his head.
 
On the reverse of 2025 1 oz Silver Kangaroo Coins is an image of a leaping kangaroo. This iconic design is based on a historic design of the animal for the Australian copper penny. In the design, it is shown in left-profile relief as it bounds along with stylized sun rays filling the background field.
