In 1990, the Perth Mint began minting the Silver Kookaburra, originally with .999 fine silver. In 2018, the purity level was increased to .9999 fine silver.

The obverse of this coin always features Queen Elizabeth II, in profile, but the reverse design features a new Kookaburra each year. Because some designs are more popular than others, silver Kookaburra coins have great collection value.

The one-ounce silver Kookaburra coins have a capped annual mintage, but other sizes are unlimited mintage, based on customer demand.

The Perth Mint is the oldest operating mint in Australia and is the official bullion mint of Australia.

The Perth Mint was one of the last three colonial mints established by the Royal Mint in London. It was established in June of 1899 and was built in order to accommodate the massive amounts of gold being discovered.
