Key Takeaways
- A gold premium is the amount you pay above the spot value of the gold in a coin or bar. On 7 October 2026, a 1 oz Kangaroo gold coin cost 3.9% over the AUD spot price at the cheapest Australian dealer we track.
- Size drives the premium. The same dealer charged 16.1% over spot for a 1/10 oz Kangaroo and 3.9% for a 1 oz Kangaroo.
- Silver costs more to buy. A 1 kg cast silver bar carried 11.9% over spot and 1 oz silver coins carried 15.6% to 33.4%.
- Shipping can change the ranking. A flat A$40 delivery fee adds almost nothing to a gold coin but can add 30 percentage points or more to a single silver coin.
- Investment gold of 99.5% purity or higher is sold without GST in Australia, so a 22 carat coin can look expensive for reasons that have nothing to do with the dealer’s margin.
Most Australians who buy gold for the first time notice the same thing. The price in the dealer’s shop is higher than the gold price on the evening news. That gap is the gold premium, and it is the biggest cost you can control when you buy physical metal.
In this guide, we explain what a gold premium is, what pushes it up or down in Australia and how much over spot you should expect to pay. Instead of rules of thumb, we use real AUD prices that our investment gold comparison collected from Australian dealers on 7 October 2026.
What Is a Gold Premium?
A gold premium is the difference between the price you pay for a gold product and the market value of the pure gold it contains. Dealers show it either as a percentage of the spot price or as a dollar amount per ounce.
The spot price is the price of one troy ounce of gold for immediate delivery in the wholesale market. In Australia, most people follow it in Australian dollars on a live gold price chart in AUD. The global benchmark for large wholesale contracts is the LBMA Gold Price, set twice a day in London in US dollars.
So why can’t you simply buy at spot? Because spot is the price of raw metal in large wholesale lots, not of a finished coin in a capsule, insured and posted to your door.
How to calculate the gold premium
The formula takes two lines:
- Premium in dollars = price you pay minus (spot price × troy ounces of fine gold)
- Premium in percent = premium in dollars ÷ (spot price × troy ounces of fine gold) × 100
Here is a worked example with our data. On 7 October 2026, gold spot was A$5,928.05 per troy ounce. Australian Bullion Company listed a 1 oz Perth Mint Kangaroo gold coin at A$6,159.00. The premium was A$230.95, which is 3.9% over spot.
For grams, divide by 31.1035, the number of grams in one troy ounce. Our troy ounce guide has a full conversion table, and the glossary entry premium over spot gives the short definition.
Premium vs spread: two different costs
People often mix these up. The premium is what you pay above spot when you buy. The bid-ask spread is the gap between the dealer’s selling price and the price at which the same dealer buys the product back from you.
Both shape your real cost. A product with a low premium and a strong buyback price loses the least value on the round trip.
What Drives Gold Premiums in Australia?
A premium is not one fee. It is a stack of costs, and each layer depends on the product, the dealer and the moment you buy. These are the main parts:
- refining, rolling, striking and quality control at the mint or refinery,
- the mint’s own margin when it sells to wholesalers and dealers,
- freight, insurance and vault storage between the mint and the shop,
- the dealer’s running costs: staff, rent, card fees, packaging and postage,
- the dealer’s profit,
- supply and demand for that exact product on that day.
Product size
Striking a 1/10 oz coin takes almost as much work as striking a 1 oz coin. The small coin holds ten times less gold, though. The fixed cost is spread over far less metal, so the percentage premium jumps. You will see this clearly in the Kangaroo table below.
Local coins vs imported coins
Australia has its own world-class producer. The Perth Mint makes the Kangaroo, Kookaburra, Koala and Lunar series, so Australian dealers can source these coins without long-haul freight. Imported coins such as the Canadian Maple Leaf or the American Eagle have to travel further, and that cost usually shows up in the price. Our guide to the best gold coins to buy in Australia compares the popular choices.
GST and purity
Investment-grade gold of at least 99.5% purity, silver of at least 99.9% and platinum of at least 99% in bar, wafer or coin form is sold without GST in Australia. Products below those lines, such as 22 carat Krugerrands and American Gold Eagles, usually carry 10% GST. That tax shows up as a higher apparent premium, even when the dealer’s own margin is small. Our glossary entry on GST on gold in Australia explains the rules and the ATO ruling behind them.
Market stress
When demand spikes, mints and refiners cannot add capacity overnight. Dealers lift premiums to slow orders, and stock of popular sizes runs short. In calm markets, competition between dealers pushes premiums back down. Spot itself moves a lot, too:
Over these 91 days, AUD spot ranged from A$5,732.78 on 20 July to A$6,501.10 on 25 August. Because the premium is measured against spot, the same dollar markup looks smaller in percentage terms when spot is high and larger when spot is low.
Payment, delivery and quantity
Many Australian dealers price bank transfer lower than card payments. Some charge a flat delivery fee, others add shipping in the cart or offer free pickup. Larger orders sometimes unlock better pricing. Always compare the final price at checkout, not the first number you see on a product page.
Gold Premiums at Australian Dealers: Our Data
What does this look like in real money? We pulled the Australian offers from the metalsradar price service on 7 October 2026: 19 listings from Australian Bullion Company and KJC Bullion, checked at 05:52 UTC. Premiums are calculated against the AUD spot price for the same day.
Perth Mint Kangaroo gold coins by size
| Kangaroo gold coin | Gold value at spot | Dealer price | Premium | Price per oz of gold |
|---|---|---|---|---|
| 1/10 oz | A$592.81 | A$688.10 | 16.1% | A$6,881.00 |
| 1/4 oz | A$1,482.01 | A$1,661.00 | 12.1% | A$6,644.00 |
| 1/2 oz | A$2,964.03 | A$3,218.00 | 8.6% | A$6,436.00 |
| 1 oz | A$5,928.05 | A$6,159.00 | 3.9% | A$6,159.00 |
The pattern is hard to miss. Buying ten 1/10 oz coins instead of one 1 oz coin would cost A$6,881.00 for the same ounce of gold, A$722.00 more. The same dealer priced the 1/10 oz and 1/4 oz gold Britannia exactly like the Kangaroo of the same size, A$688.10 and A$1,661.00.
Live prices for every size are on our Kangaroo gold coin price comparison and the cheapest gold coins in Australia page.
Gold bars and CombiBars
Bars usually carry lower premiums than coins of the same weight, because they need less design work and no legal tender status. One exception is the CombiBar, a bar scored into small 1 g or 1/10 oz pieces that you can snap off and sell separately. That flexibility costs extra.
| Valcambi CombiBar (KJC Bullion) | Gold value at spot | Dealer price | Premium | Premium incl. A$40 delivery |
|---|---|---|---|---|
| 20 g (20 × 1 g) | A$3,811.82 | A$4,346.60 | 14.0% | 15.1% |
| 50 g (50 × 1 g) | A$9,529.56 | A$10,553.04 | 10.7% | 11.2% |
| 100 g (100 × 1 g) | A$19,059.12 | A$21,073.94 | 10.6% | 10.8% |
| 1 oz (10 × 1/10 oz) | A$5,928.05 | A$6,640.07 | 12.0% | 12.7% |
Compare the last row with the Kangaroo table. One ounce of gold as a CombiBar cost A$481.07 more than a 1 oz Kangaroo coin on the same day. If you want small pieces for flexibility, a CombiBar can still be cheaper than ten separate 1 g bars. If you only want one ounce of gold, it is the expensive route. Regular cast and minted bars are listed on our gold bar price comparison and the 1 oz gold bars page.
Dated and collector coins
Two KJC Bullion listings show how far a premium can stretch:
- a 2 oz 2024 Australian Year of the Dragon gold coin at A$12,812.55, which is 8.1% over its gold value of A$11,856.10,
- a 1990 South African Krugerrand at A$7,735.23, which is 30.5% over the value of its one ounce of fine gold.
The Krugerrand is a special case in Australia. It is 22 carat gold, below the 99.5% purity line, so dealers generally add GST. A specific year also attracts collector pricing. Neither of those is a plain bullion premium. Read more in our entry on numismatic coins.

Silver Premiums: Why They Are Higher
Silver is worth roughly 68 times less than gold per ounce on our 7 October 2026 data (A$5,928.05 against A$87.16). Minting, freight and storage cost about the same per coin or per kilo, though. Those costs are large relative to the metal value, so silver premiums are higher in percentage terms.
| Silver product | Dealer | Silver value at spot | Dealer price | Premium |
|---|---|---|---|---|
| 1 kg ABC cast silver bar | Australian Bullion Company | A$2,802.26 | A$3,137.00 | 11.9% |
| 1 oz Maple Leaf | Australian Bullion Company | A$87.16 | A$100.75 | 15.6% |
| 1 oz silver Krugerrand | Australian Bullion Company | A$87.16 | A$100.75 | 15.6% |
| 1 oz Britannia | Australian Bullion Company | A$87.16 | A$108.90 | 24.9% |
| 1 oz Liberty silver coin | Australian Bullion Company | A$87.16 | A$108.90 | 24.9% |
| 1 oz American Silver Eagle (mixed dates) | KJC Bullion | A$87.16 | A$116.24 | 33.4% |
| 100 g Valcambi CombiBar (10 × 10 g) | KJC Bullion | A$280.23 | A$475.42 | 69.7% |
Notice the size effect again. A 1 kg cast bar cost A$97.57 per ounce of silver, while the cheapest 1 oz coin cost A$100.75. Now add delivery. KJC Bullion’s A$40 fee lifts the effective premium on a single Silver Eagle from 33.4% to 79.3%. On a small silver order, delivery can cost more than the premium itself. Compare silver options on our 1 kilo silver bar prices and cheapest silver coins pages, and see whether silver suits you in gold vs silver investments for Australians.
How Much Over Spot Should You Pay for Gold in Australia?
There is no fixed fair premium. It moves with spot, demand and the product. Our 7 October 2026 data gives a useful benchmark for what was on offer that day:
| Product | Premium seen on 7 October 2026 | What it tells you |
|---|---|---|
| 1 oz Kangaroo gold coin | 3.9% | The cheapest gold product per ounce in our Australian sample |
| 1/2 oz gold coin | 8.6% | Roughly double the 1 oz premium |
| 1/10 oz and 1/4 oz gold coins | 12.1% to 16.1% | Fine for gifts, costly for building a holding |
| Gold CombiBars, 20 g to 1 oz | 10.6% to 14.0% | You pay for divisibility |
| 1 kg silver bar | 11.9% | The lowest silver premium in our sample |
| 1 oz silver coins | 15.6% to 33.4% | Brand and origin matter a lot |
So what does this mean for you? If a dealer quotes much more than these levels for the same product, ask why. Sometimes there is a good reason, such as a specific year, proof finish or GST on a 22 carat coin. Often there is not.
How to Pay a Lower Gold Premium
You cannot remove the premium, but you can shrink it. These steps work for most Australian buyers:
- Buy bigger units: one 1 oz coin instead of several fractional coins, if your budget allows.
- Prefer local bullion: Perth Mint coins and Australian-made bars often cost less than imported coins of the same weight.
- Check the purity line: 99.5% gold and 99.9% silver are sold without GST, while 22 carat coins usually are not.
- Skip specific years: random-year or mixed-date bullion is normally cheaper than a named year.
- Count delivery: divide the shipping fee by the metal value of your order and add it to the premium.
- Compare on the same day: premiums only make sense against the spot price at the moment you buy.
The last step is the one most people skip. Our Australian bullion dealers page ranks offers by the final price including delivery, then shows the premium against today’s spot. That is the fairest way to compare two shops.
Does a low premium always mean a better deal?
No, not always. A low premium is only half of the round trip. When you sell, the dealer pays you a buyback price, and that is often below spot. Widely traded products such as the Kangaroo, the Maple Leaf and LBMA-approved bars are easiest to sell back. A rare product with a slightly lower premium may be harder to resell at a fair price.
Is the premium worth paying at all?
For most physical buyers, yes. The premium buys you metal you hold yourself, with no fund manager or bank in between. If that ownership matters less to you than cost, paper products may suit you better, but they come with their own fees and risks.
