The obverse features the head of state of the British Commonwealth, Elizabeth II, along with the weight of the coin, its purity and face value. The face value of the 1 ounce coin is A$100.

The reverse features the bold frontal view of a Rat. "Year of the Rat" is imprinted along the bottom of the coin. The Perth Mint’s traditional ‘P’ mintmark is also inscribed on the left of the coin.
