1 oz Southern Cross Gold Coin

ABC Refinery's Southern Cross Gold Coin

The 1 oz ABC Refinery Southern Cross Gold Coin is a bullion coin launched in June 2025 by ABC Mint, a division of Pallion, which also encompasses ABC Refinery, Australia's largest and only LBMA-accredited gold refinery. The coin was conceptualised by Ross MacDiarmid AO, former CEO of the Royal Australian Mint, and illustrated by coin artist Tony Dean.

The Southern Cross contains one troy ounce of .9999 fine gold, struck as Niue legal tender with a face value of NZD $100 (Niue uses the New Zealand dollar). The reverse depicts two iconic Australian animals, a kangaroo and an emu, in silhouette against the outback landscape, gazing upward toward the five stars of the Southern Cross constellation (Crux). These two animals appear on Australia's coat of arms and are commonly noted for being unable to walk backwards, symbolising forward progress.

The collection is an open, unlimited edition, positioning it as an accessible bullion investment product priced on metal market value plus a modest premium. This contrasts with limited-mintage collectible coins and places the Southern Cross in direct competition with the Perth Mint Kangaroo as an Australian-origin gold bullion coin.

ABC Refinery's LBMA accreditation and domestic refining operations mean the Southern Cross offers a complete Australian provenance chain: Australian-mined gold, refined domestically by an LBMA-accredited facility, and struck into coins by ABC Mint in Sydney. This mine-to-coin traceability is uncommon in the bullion industry, where most mints source refined gold from international suppliers.

Southern Cross 1 oz Gold Coin Specifications

The gold range extends across multiple weight classes: 1/10 oz ($2), 1/4 oz ($25), 1/2 oz ($50), 1 oz ($100), and 2 oz ($200), with a 10 oz version also listed. Silver coins are struck to .9999 purity, notably higher than the .999 standard used by most silver bullion programmes, with a high-relief BU finish available in 1 oz, 10 oz, and 1 kg sizes.

The obverse carries the King Charles III effigy approved by New Zealand and Buckingham Palace authorities, alongside Niue legal tender details. The Niue arrangement is a common model for private mints seeking legal tender status, used by mints globally to secure the sovereign coin classification needed for tax-exempt treatment in many jurisdictions.

Tax Treatment for the Southern Cross Gold Coin

Australia

Gold bullion coins meeting the investment-grade criteria (purity of .995 or higher, in a form commonly traded on commodity markets) are GST-exempt in Australia. The Southern Cross qualifies at .9999 purity. ABC Bullion confirms that most of their bullion coins are sold GST-free. There is no CGT exemption for bullion coins in Australia; profits on disposal are subject to capital gains tax, with a 50% discount for holdings over 12 months.

New Zealand

As Niue legal tender denominated in NZD, the Southern Cross has a direct connection to the New Zealand dollar system (Niue is a New Zealand-associated state). Fine gold bullion of .995 or higher purity is GST-exempt in New Zealand. The .9999 purity qualifies.

United Kingdom

Gold coins meeting the investment gold criteria (legal tender, post-1800, purity of .900 or higher) are VAT-exempt. The Southern Cross qualifies as Niue legal tender with .9999 purity. It is not CGT-exempt, as that relief applies only to UK legal tender coins. Capital gains above the annual allowance (currently £3,000) are taxed at the individual's rate.

United States

No federal sales tax. State-level exemptions vary. The .9999 purity and legal tender status support potential IRA eligibility under Section 408(m), which requires gold of .995+ fineness.

Singapore

Gold meeting IPM criteria (.995+ purity in qualifying form) is GST-exempt. The Southern Cross should qualify, though it may need to appear on the MAS-approved coin list for automatic recognition.

Canada

Gold coins of .995 or higher purity are exempt from GST/HST. The Southern Cross qualifies at .9999.

Southern Cross vs Perth Mint and International Gold Coins

The most direct comparison is the 1 oz Perth Mint Kangaroo, Australia's established sovereign gold bullion coin. Both are .9999 fine gold, both feature Australian iconography (kangaroo motifs), and both carry legal tender status (Australian dollars for the Kangaroo, NZD for the Southern Cross). The Perth Mint has decades of global brand recognition, established buyback networks with dealers worldwide, and the backing of the Government of Western Australia. The Southern Cross is a newer entrant with the ABC Refinery provenance story and domestic refining chain as its primary differentiator.

The silver versions present a more distinctive comparison. The Southern Cross silver coin is .9999 fine, matching the 1 oz Canadian Silver Maple Leaf and exceeding the .999 purity of most silver bullion coins including the Perth Mint Kookaburra and Koala. For silver buyers specifically, the four-nines purity is a genuine point of difference.

Against the 1 oz Canadian Maple Leaf, the Southern Cross matches on purity but faces the same recognition gap that any new programme has against a series running since 1979. The Maple Leaf's micro-engraved security features and DNA anti-counterfeiting technology also set a high bar that the Southern Cross does not currently match.

For Australian buyers, the choice often comes down to whether the ABC Refinery provenance and domestic manufacturing chain carry meaningful value beyond what the Perth Mint offers. Both products deliver the same gold content at comparable premiums. The Southern Cross appeals particularly to buyers who value the LBMA-accredited Australian refining story or who prefer the aesthetic of the kangaroo-and-emu constellation design over the Perth Mint's annual rotating kangaroo motif.
