Australian Silver Coins
Australian silver coins encompass a broad range of legal-tender bullion and numismatic issues struck by the Perth Mint and the Royal Australian Mint. The category includes iconic ongoing series as well as limited annual releases, spanning denominations from small fractional coins up to large-format kilo and multi-kilo pieces. Most bullion-grade issues carry a fineness of .9999 silver, with the standard one-troy-ounce size being the most widely traded format. Australia has built one of the most recognized national silver coin programs in the world, with series such as the Silver Kangaroo, Kookaburra, Koala, Lunar, and the wildlife-themed releases — of which the Saltwater Crocodile is a notable example — all produced under the Perth Mint's hallmark. Each series typically features annually rotating reverse designs centered on Australian fauna, culture, or the Chinese lunar calendar, while the obverse carries the effigy of the reigning British monarch as legal tender of Australia. The combination of high-purity silver, detailed relief work, and changing annual designs makes these coins a distinct corner of the world bullion market. On this page, CoinDuffle brings together listings from multiple dealers covering a range of years, series, and formats within the Australian silver coin universe. Buyers will find individual one-ounce coins, multi-coin sets, proof issues, and occasionally larger-weight pieces. The breadth of available years and series means both date-run collectors and those seeking a specific design or mintage can browse efficiently across a competitive dealer network.

Frequently asked questions
The most widely collected Australian silver series include the Perth Mint's Silver Kookaburra, Silver Koala, Silver Kangaroo, and Lunar Series (I, II, and III), along with individual wildlife releases such as the Saltwater Crocodile. Each series typically issues new reverse designs annually, making year-specific editions a natural focus for date-run collectors.
The vast majority of Australian silver bullion coins are struck in .9999 fine silver — among the highest purity used in any national bullion program. The one-troy-ounce denomination is the most common format, though many series also appear in fractional sizes (1/2 oz, 1/4 oz) and larger weights including 5 oz, 10 oz, 1 kilo, and beyond.
Most collectible and bullion Australian silver coins are produced by the Perth Mint, a Western Australian government-owned enterprise with origins dating to 1899. The Perth Mint holds a global reputation for high-relief, finely detailed coin production. The Royal Australian Mint in Canberra also issues silver commemoratives, though the Perth Mint handles the majority of bullion series.
For most major series — including the Kookaburra, Koala, and Lunar — the reverse design changes annually by design. This rotating-design format is a defining characteristic of Australian silver programs and is a primary driver of collector demand for specific date issues. The obverse, featuring the monarch's effigy, also updates periodically to reflect the current portrait standard.
