| Obverse description | The fourth crowned effigy of Queen Elizabeth II faces right, rendered by engraver Ian Rank-Broadley, with the Queen wearing the Girls of Great Britain and Ireland Tiara. The legend arcs around the upper field reading 'ELIZABETH II AUSTRALIA 1 DOLLAR', with the designer's initials 'IRB' incused below the portrait truncation. The design follows the standard Commonwealth portrait introduced in 1998. |

| 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.
