The Perth Mint — Australia

1 Kilogram Cast
Gold Bar

1,000 grams of 99.99% pure gold from The Perth Mint — Australia's largest gold refinery. The 1kg bar is the most cost-efficient way to accumulate gold, carrying the lowest premium per gram of any retail product we stock.

Lowest premium per gram. At 1kg, the buy premium drops to approximately 1.5% over spot — compared to 3–5% for smaller bars. For serious investors accumulating physical gold, this is the most capital-efficient weight available at retail.

The Perth Mint 1 Kilogram Cast Gold Bar is the most capital-efficient gold product available to retail investors in Australia. Each bar is poured from molten gold into a mould, stamped with The Perth Mint's swan hallmark, the bar's weight (1 KILO FINE GOLD 9999), and a unique serial number. It is then individually weighed and verified before leaving the Mint.

As a cast bar, the surface texture is organic rather than mirror-polished — minor surface variations, crystalline grain structure, and flow marks are normal characteristics of the casting process and do not affect the bar's gold content or resale value. The gold content is identical to any minted product of equivalent weight.

As an authorised Perth Mint dealer, every bar we supply comes directly from The Perth Mint with full chain of custody. Solomons Bullion buys this bar back at 100% of the live spot price — the tightest buyback spread available in Australia.

The London Bullion Market Association (LBMA) Good Delivery standard is the global benchmark for wholesale gold bar quality. To appear on the LBMA Good Delivery List, a refinery must meet stringent requirements for purity, weight tolerance, hallmarking, and quality control.

The Perth Mint is one of only a handful of refineries globally to hold full LBMA Good Delivery accreditation. This means every bar it produces is:

  • Accepted at face value by every major bullion bank and dealer worldwide
  • Eligible for delivery against COMEX and LBMA gold futures contracts
  • Recognised by central banks as qualifying reserve gold

For the investor, LBMA accreditation means maximum global liquidity — you can sell this bar to any reputable dealer in any country with no questions asked about its provenance.

A 1kg gold bar at current prices represents a significant holding. Storage considerations at this size are different from smaller products:

  • Home storage: Most home contents policies exclude or severely limit gold. A dedicated home safe rated for this value is an additional cost. The bar must be stored in a way that maintains its condition.
  • Professional vault: Our allocated vault storage is 0.15% per annum of holding value — on a $350,000 bar, that's approximately $525 per year. Includes Lloyd's of London insurance at full replacement value, annual independent audit, and the ability to sell without taking delivery.

For holdings of this size, professional allocated storage is almost always the more cost-effective and secure option. Your first 3 months are free with every purchase.

Investment-grade gold (≥99.5% pure) is exempt from GST under Australian law. This bar is GST-free. Selling is a Capital Gains Tax event. If held for more than 12 months, the 50% CGT discount applies to individuals. For SMSF holdings, capital gains in accumulation phase are taxed at 15% (10% with the 12-month discount). A detailed tax invoice is issued for every purchase — retain this for CGT records.

For orders of this size, we strongly recommend calling ahead on 1300 000 000 to arrange the transaction. This allows us to prepare the specific bar, confirm identification requirements, and arrange secure delivery or vault placement before your visit.

Delivery is by specialist high-value courier with full replacement-value insurance. For orders above $250,000, we may require additional security arrangements for delivery — our team will discuss this with you. In-person collection at either our Sydney or Melbourne office is always available at no cost.

Why the 1 Kilogram Bar

The choice of serious gold investors worldwide
Lowest Premium Per Gram

At 1kg, the buy premium above spot drops to approximately 1.5% — compared to 3–5% for 1oz bars and 10–15% for gram-sized products. Every dollar goes further toward actual gold content. For large allocations, the premium saving is meaningful.

Maximum Global Liquidity

LBMA Good Delivery bars from The Perth Mint are the most liquid bullion product in the world at the wholesale level. Any major dealer, bank, or exchange globally will accept this bar at face value. For investors who may need to liquidate quickly or offshore, this is the optimal format.

SMSF & Institutional Grade

The 1kg bar is the standard weight used in institutional gold trading and SMSF portfolios. It provides the right balance between concentration and practicality — large enough to minimise transaction costs, small enough to be individually allocated and audited.
