Five hundred grams of 999.9 fine gold — 16.07 troy oz — from ABC Bullion, Australia's largest privately-owned bullion dealer and LBMA-accredited refinery. At this size, the buy premium drops to approximately 1.7% above spot, making the 500g bar one of the most cost-efficient retail gold products available in Australia before the step up to a full kilogram.
The ABC Bullion 500 Gram Cast Gold Bar is a pour-moulded bullion bar produced by Australia's largest privately-owned refinery. The ABC logo is cast into the upper surface alongside the weight (500g), fineness (FINE GOLD 999.9), and the CHI Essayeur Fondeur certification mark — the internationally recognised assay standard confirming the bar's metal content and purity.
Each bar carries a unique serial number. As a cast bar, the surface has an organic texture characteristic of the moulding process — flow marks and minor surface variations are normal and do not affect the bar's gold content or resale value. The bar is accepted at face value by any major bullion bank, dealer, or exchange worldwide.
At 500g, this is one of the largest retail bars available in Australia before the 1kg step up. It is popular with investors who want near-institutional premium efficiency while maintaining a single-bar transaction rather than acquiring multiple smaller bars.
At approximately 1.7% above spot, the 500g bar sits between the 100g (~2.0–2.5%) and the 1kg (~1.5%) on the premium curve. Buying five 100g bars costs more in premium per gram than a single 500g bar — the premium difference across a ~$400,000 holding at current prices can exceed $3,000.
For investors whose budget comfortably reaches 500g but who are not yet ready to commit to a full kilogram in a single transaction, the 500g represents the optimal balance of premium efficiency and transaction size. It is also the maximum retail bar size that many advisers recommend for home storage purposes before the cost of appropriate home safe infrastructure becomes meaningful.
At current prices, a 500g gold bar represents a significant asset. Key considerations:
First 3 months of storage are free with every purchase. We strongly recommend vault storage for holdings of this size.
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. SMSFs in accumulation phase are taxed at 15% (10% with the 12-month discount). A detailed tax invoice is provided for every purchase. Retain for CGT records. Seek independent tax advice for your circumstances.
We recommend calling ahead on 1300 000 000 to arrange large transactions. This allows us to confirm identification requirements and arrange secure delivery or vault placement before your visit. Delivery 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 office is always available at no cost.
At ~1.7% above spot, the 500g bar captures most of the premium advantage of a 1kg bar at half the outlay. Five 100g bars would cost meaningfully more in aggregate premium — the 500g is the smarter single-purchase alternative at this price point.
ABC Bullion is a fully LBMA-accredited refinery. This bar is accepted at face value by any major bullion bank, dealer, or exchange worldwide without further assay. CHI Essayeur Fondeur certification provides an additional layer of recognised international assay endorsement.
At this size, professional allocated vault storage becomes the compelling choice. Our 0.15% p.a. storage fee on a 500g bar costs approximately $195/year — less than a home safe rated for this value, and including Lloyd's of London full replacement insurance and annual independent audit.
