Cast silver bars
12 sizes · lowest price across all brands
Silver cast bars from every Australian bullion dealer, sorted by size. Cast bars carry the lowest premiums of any silver product and are the most cost-efficient way to accumulate silver in Australia. All prices include GST.
What is a cast silver bar
A cast silver bar is produced by pouring molten silver into a mould and allowing it to cool. The surface is rougher and more irregular than a minted bar, with no polish or elaborate packaging. What cast bars lack in presentation they make up for in value: they consistently carry the lowest premiums of any silver product.
For Australian investors focused on accumulating as much silver as possible per dollar spent, cast bars are the obvious choice. The 1kg cast bar is the most popular size among Australian silver investors, offering a good balance between cost efficiency and practical handling. The cheapest 1kg silver bars page shows current prices across all dealers for this size specifically.
Why cast silver bars are popular with Australian investors
Cast bars deliver more silver per dollar than any other product. A 1kg cast silver bar from ABC Bullion or the Perth Mint typically carries a premium of 4 to 8 percent over the silver spot price. An equivalent minted bar might carry a premium of 8 to 14 percent. On a 10kg purchase, that difference is A$150 to A$300.
For investors who are stacking silver regularly, buying cast bars instead of minted is one of the simplest ways to improve long-term returns. The lower entry cost means more silver for the same outlay, and the resale price from Australian dealers is the same regardless of whether the bar was minted or cast (it is priced by weight and purity). If you want to compare silver against gold, the gold cast bars page shows equivalent gold products.
1kg cast silver bars: the most popular size in Australia
The 1kg cast silver bar is by far the most popular silver product among Australian investors. It is large enough to attract the lowest premiums in the cast bar range, small enough to be practical, and stocked by every major dealer in Australia.
ABC Bullion's 1kg cast silver bar is frequently among the cheapest available in Australia because it is produced domestically. The Perth Mint's 1kg cast bar is slightly more expensive but carries stronger international resale recognition. Swan Bullion is also consistently competitive on the 1kg size.

GST on silver cast bars in Australia
Silver cast bars are subject to the 10 percent GST, included in all prices on this page. This is the same for all silver products in Australia. Gold investment products are GST-free, which is one reason some investors favour gold for their primary precious metals allocation.
If you are deciding between silver and gold, the GST on silver means you need a larger price gain to reach breakeven. For a full explanation of the GST rules across different precious metal products, see the gold GST guide. For investors who want a GST-free precious metal, the gold bars page lists both cast and minted gold bars.
Silver as an investment in Australia
Silver's price is more volatile than gold and is influenced by both investment demand and industrial demand (particularly from solar panels, electronics, and electric vehicles). This dual demand can create sharp price movements in both directions.
Many Australian investors hold silver as a complement to gold rather than a replacement. A common approach is to use gold coins or gold bars as the core holding for capital preservation, and silver cast bars as a higher-upside, higher-volatility component. For a broader view of how to structure a precious metals portfolio, the how to buy gold guide covers the key considerations even though its focus is on gold.
