| 背面描述 | A highly detailed depiction of a koala (Phascolarctos cinereus) seated upright on a log, facing slightly left, holding and chewing eucalyptus leaves. The naturalistic design is rendered in high relief with fine textural detail in the animal's fur. The circular legend 'THE AUSTRALIAN KOALA 1/2 OZ. 9995 PLATINUM' arcs around the upper and right periphery, with the date '1999' at the base, all within a beaded border. The Perth Mint privy mark 'P100' appears in the lower right field. |

Australia's platinum koala series launched in 1987, making Perth one of the earliest sovereign mints to issue a dedicated investment bullion program in platinum. The annual design change on the reverse was a deliberate marketing decision to drive collector demand alongside bullion buyers — a strategy borrowed partly from the Canadian Maple Leaf's success but differentiated by varying imagery rather than a static design.
Ian Rank-Broadley's fourth portrait of Elizabeth II, introduced across Commonwealth coinage in 1998, first appeared on this series during this exact two-year window.
