1 Kilo Perth Mint Koala Platinum Coin

The Perth Mint's Heavyweight Platinum Koala

The 1 Kilo Platinum Koala represents the largest denomination in the Perth Mint's now-discontinued platinum Koala series, which ran from 1988 to 2000. At 32.15 troy ounces of .9995 fine platinum, this is a serious holding for investors who want concentrated platinum exposure in a single government-backed coin. The kilogram size was introduced in 1991, three years after the series launched with the smaller 1 oz denomination.

Perth Mint's platinum program was groundbreaking. The Koala series was among the first national mint programmes to offer platinum bullion in a full range of sizes, and it processed over 18 tonnes of platinum during its 12-year production run. The 1 kg denomination carried a face value of AUD $3,000, though its metal content was always worth multiples of that figure. Like all Platinum Koalas, the kilogram coin featured annual reverse design changes showing koalas in various natural Australian settings.

The series ceased production in 2000 after sustained low demand for physical platinum investment. Just 2,048 one-ounce coins were struck in that final year against a maximum of 100,000, illustrating how thin the platinum market had become. The kilogram denomination was produced in even smaller quantities. Any 1 kg Platinum Koala available on the secondary market today is from a finite pool that will never be replenished, which gives these coins significance beyond their raw metal content.

For buyers considering this coin, the primary comparison is against modern 1 kg platinum bars from LPPM-accredited refiners such as PAMP Suisse or Heraeus. The bar route typically carries lower premiums, but the Koala offers legal tender status, government guarantee from the Government of Western Australia, and potential numismatic appreciation given its discontinued status. Against other large-format platinum coins, the main alternative is the 1 oz Big 5 Platinum from the South African Mint, though that caps at one ounce.

1 Kilo Platinum Koala Technical Details

The coin's 75.3 mm diameter and 13.9 mm thickness make it a substantial piece. Platinum's density of 21.45 g/cm3 means this kilogram coin is actually more compact than a kilogram of gold (density 19.3 g/cm3) would be at equivalent dimensions. The reeded edge and "P" mintmark are consistent with all Perth Mint bullion products from this era.

Each year of production featured a unique reverse showing koalas in different poses and settings, drawn from the eucalyptus forests of Australia. The obverse carried the portrait of Queen Elizabeth II in the Raphael Maklouf effigy used through this period. Coins were supplied in Perth Mint capsules.

Tax Position for 1 Kg Platinum Koala Buyers

Platinum receives less favourable tax treatment than gold in most jurisdictions. The combination of purchase taxes and capital gains taxes on platinum means buyers should carefully consider their country's rules before acquiring a coin of this value.

• Australia: GST-free. As an investment-grade platinum coin (99.95% purity) from the Perth Mint, this qualifies for the precious metals GST exemption. Subject to capital gains tax on disposal, with a 50% discount for holdings over 12 months.
• United Kingdom: Subject to 20% VAT on purchase. Not UK legal tender, so profits are also subject to CGT at 18-24%. The 20% entry cost on a coin worth tens of thousands of pounds is substantial. VAT-free vault storage is available from some UK dealers as an alternative to physical delivery.
• United States: IRA-eligible. The Perth Mint Platinum Koala is specifically listed as qualifying for precious metals IRAs under IRS Section 408(m). Sales tax treatment varies by state. Capital gains taxed at the 28% collectibles rate for long-term holdings.
• Canada: GST/HST exempt for platinum at 99.5% purity or above. The .9995 Koala exceeds this threshold.
• New Zealand: GST-exempt for platinum at 99% purity or above. No capital gains tax in NZ.
• Singapore: GST-exempt under the Investment Precious Metals (IPM) scheme. Platinum at 99% purity or above from a recognised mint qualifies. No capital gains tax.
• Hong Kong: No sales tax, no import duty, no capital gains tax. Fully tax-free.
• South Africa: Subject to 15% VAT on platinum. No platinum-specific exemption exists comparable to the gold Krugerrand's zero-rating.
