| Reverse description | The central field displays a group portrait of six individuals of diverse ethnic backgrounds rendered in relief, with pad-printed colour applied in teal and blue tones to suggest the multicultural character of Australian society. The curved legend AUSTRALIAN KOALA arcs across the upper field within a beaded border. The inscriptions Australian Stories - Multiculturalism appear diagonally across the central design, flanked by the specifications 1 OZ. and .9995 to the left and PLATINUM to the right along the lower periphery. The date 2002 and the Perth Mint's P mintmark appear at the base of the design. |

| Additional information |
Australia's 2002 platinum Koala series marked the first year Perth used pad printing on a bullion coin — a technique borrowed from industrial manufacturing that allowed color application directly onto the metal surface without the use of a separate insert. The "Multiculturalism" designation placed this piece within a themed sub-series celebrating Australian national identity, issued alongside gold and silver variants of varying denominations.
Pad printing adhesion on platinum proved technically demanding, and quality consistency across the 2002 run was uneven enough that the method was refined in subsequent years.
