| Reverse description | Central high-relief depiction of a koala (Phascolarctos cinereus) seated facing three-quarters left on a grassy mound, rendered with exceptional naturalistic detail in its fur and claws. To the right, a large eucalyptus trunk with drooping leaves extends beyond the coin's border; to the left background, a solitary eucalyptus tree stands against a horizon line suggesting an open landscape. The legend AUSTRALIAN KOALA arcs along the upper periphery. Along the lower arc, the inscription 2017 1oz 9999 GOLD identifies the year, weight, and fineness. The Perth Mint's P mintmark and the designer's initials TV appear to the left of the central device. |

| Additional information |
Perth Mint's high-relief gold program has consistently pushed the technical limits of what a single-sided die strike can achieve, and the 2017 Koala issue is no exception — the format demands multiple strikes at elevated pressure to fully raise the design field, a process that also compresses and work-hardens the planchet surface in ways a standard proof strike does not. Elizabeth II's fourth portrait, by Ian Rank-Broadley, was used on Australian coinage from 1998 until its replacement in 2019, making this one of the later issues to carry it.
