This one-kilo version is among the largest government-issued silver coin in the world.
The design of the reverse of the coin changes annually. The reverse design in 2009 depicts the image of an ox.
Issued as legal tender under the Australian Currency Act 1965, the coin bears the Ian Rank-Broadley effigy of Her Majesty Queen Elizabeth II on its obverse.
Like its predecessors, the 2013 Silver Koala is struck on a 'mint-to-order' basis only. Production closes on announcement of the 2014-dated coin, enabling The Perth Mint to declare its official mintage.
