Produced by the Perth Mint, the Koala Series has been released in silver since 2007, featuring a new Koala design each year. Coins are available in four sizes: 1 kg, 10 oz, 1 oz, and 1/2 oz.

All coins come in protective capsules, with orders of 20 delivered in mint-sealed rolls. This release is limited to a maximum mintage of just 300,000 pieces for the first time ever.
