Celebrate the raw, untamed beauty of Australia's vast interior with the 2026 Wonders of Australia – The Outback 1oz Silver Proof Opal Coin from The Perth Mint. This stunning proof release honours the awe-inspiring landscapes and unique biodiversity of the Australian outback—a sprawling region of deep canyons, arid deserts, ancient rock formations, and resilient wildlife that spans millions of square kilometres and supports hundreds of thousands of species found nowhere else on Earth. At the heart of the design is a genuine Australian opal insert, Australia's national gemstone, displaying fiery blues, greens, and flashes of colour in a mosaic-like pattern that evokes the shimmering night skies and mineral-rich earth of the outback.

The reverse features a circular border of finely engraved native fauna—including emus, dingoes, bilbies, echidnas, blue-tongued skinks, perenties, rock wallabies, desert tree frogs, spinifex pigeons, and more—arranged clockwise around the central opal, with representations of the sun, arid terrain, and The Perth Mint's 'P' mintmark. The obverse displays the effigy of King Charles III by Dan Thorne, encircled by inscriptions for the face value ($1 AUD), year (2026), and purity. Struck from 1oz of 99.99% pure silver to proof quality, the coin arrives in a premium FSC-accredited timber veneer display case with a matching illustrated shipper and numbered certificate of authenticity. Strictly limited to 5,000 pieces worldwide, each opal's natural variations ensure your coin is truly one-of-a-kind—a perfect tribute to the wonders of the outback for collectors of Australian themes, wildlife, or precious opal-enhanced numismatics.
