This Koala piece was released in 2012 by the Perth Mint as part of the eight coin Opal series. The series features unique nocturnal creatures finished with striking opal designs. The reverse of this particular coin features a panel design of a Koala perched in a gumtree detailed in pure opal. The outer reverse panel features Eucalyptus leaves and the southern cross with the legend 'KOALA.' The obverse features the Ian Rank-Broadley portrait of HM Queen Elizabeth II with the legend 'ELIZABETH II - AUSTRALIA - 1 DOLLAR.'

The Koala is an extremely unique marsupial native to Australia. They can be found throughout eastern Australia in open eucalyptus woodlands where they subsist primarily on eucalyptus leaves. The low nutrient content of these leaves means that Koala's are forced to remain sedentary, sleeping for up to 18 hours a day. The destruction of their natural habitat has led to the Koala being classified as vulnerable under IUCN's Red List.
