Cheapest 1oz Gold in Australia 2026: Coins and Bars Compared

Why Compare Coins and Bars Together?

Most comparison sites show coins separately from bars. That misses the point. If your goal is to buy one troy ounce of gold at the lowest possible price, the cheapest option might be a cast bar this week and a coin next week. Dealer stock, promotions, and import costs all shift the balance.

The table above shows every 1oz gold product currently available from leading Australian dealers, sorted strictly by price. Coins and bars compete side by side. The cheapest option is always at the top.

Filter notes: All products contain 1 troy ounce (31.1g) of fine gold. American Eagles and Krugerrands are 22-carat but still contain exactly 1oz of gold — the small alloy addition is in addition to the gold content. Because they are below 99.5% purity, GST applies to them in Australia: their prices include 10% GST, so their premium over spot is not directly comparable with 99.99% coins and bars.

What Makes One Option Cheaper Than Another?

The premium — the amount you pay above the live gold spot price — varies based on several factors.

For bars: Cast bars (poured into moulds) carry lower premiums than minted bars (machine-stamped with a polished finish and assay card). ABC Bullion and Ainslie Bullion cast bars frequently appear near the top of the rankings.

For coins: Perth Mint Kangaroos are typically the cheapest coin because there is no import cost or currency conversion. Imported coins (Maple Leaf, Philharmonic, Eagle) carry freight and hedging costs that flow into the premium. 22-carat coins such as the Eagle and Krugerrand also carry 10% GST, because they are below the 99.5% purity threshold.

For both: High-volume dealers with warehouse operations and low overhead consistently offer lower premiums than boutique retailers. Dealer margin is a real variable in the price.

Coins vs Bars: Which Is the Better Buy at 1oz?

At the 1oz size, the premium gap between coins and cast bars is typically small, around 0.5 to 2%. Whether that gap is worth paying depends on your priorities.

Buy a cast bar if: You want the maximum amount of gold per dollar. You intend to sell back to a dealer. You are not concerned about presentation or collectability.

Buy a coin if: You want the most liquid product. You may sell privately in future (coins are easier to verify for non-specialist buyers). You are buying as a gift. You want a product that is universally recognised globally.

Most Australian investors hold a mix of both over time. For your first 1oz gold purchase, the cheapest product in the table is rarely the wrong choice.
