| Reverse description | Two koalas are depicted in high relief seated together on the branch and trunk of a eucalyptus tree, with characteristic gum leaves rendered in fine detail to the left and lower right of the field. The larger koala faces right while a smaller companion rests beside it, conveying a naturalistic and intimate composition. The legend 'AUSTRALIAN KOALA' arcs boldly across the upper field, with the Perth Mint 'P' mintmark positioned to the right of the design. The lower exergue carries the inscriptions '2011 1oz. 999 SILVER', confirming the date, weight, and fineness of this bullion issue. |

| Additional information |
Perth Mint's annual silver Koala series launched in 2007 specifically to compete with established bullion programs like the Canadian Maple Leaf and American Silver Eagle in the global investor market. Each year's reverse design changes — a deliberate strategy to encourage both collector and stacker demand simultaneously. The 2011 issue falls within the Ian Rank-Broadley obverse portrait period, the fourth effigy of Elizabeth II adopted by Australian coinage in 1998.
Mintage for the 2011 one-ounce silver Koala was capped at 500,000 pieces.
