| Additional information |
Australia's platinum Koala series launched in 1987 as a direct challenge to the dominant Canadian Maple Leaf in the international bullion market. Perth Mint positioned the fractional and one-ounce denominations to attract European investors who were already comfortable with platinum as a monetary-adjacent asset — a calculation that proved largely correct, with strong early uptake in West Germany and Switzerland.
The third portrait of Elizabeth II, by Raphael Maklouf, was adopted across Australian coinage from 1985 following the standard Commonwealth rotation schedule coordinated through the Royal Mint in London.
