Most first-time buyers pick a size by budget alone. That works, but it can cost you more than you think.<\/p>\n<p>In this guide, we explain the common gold bar sizes sold in Australia, how much each one weighs in grams and troy ounces, and what each size really cost on 11 November 2026 using our own <a href=\"\/au\/categories\/gold-bars\/\">gold bar price comparison<\/a>. You will also see how the premium over spot changes with size, and how to choose the bar that suits your plan.<\/p>\n<h2>What Gold Bar Sizes Can You Buy in Australia?<\/h2>\n<p>A gold bar is a piece of refined gold, usually 99.99% pure, stamped with its weight, fineness and the name of the refiner. Australian dealers sell bars in both metric and imperial weights, because the local market grew up with grams while the global market still prices gold per troy ounce.<\/p>\n<p>Here are the sizes you will meet most often:<\/p>\n<ul>\n<li>small bars: 1 g, 2 g, 5 g and 10 g,<\/li>\n<li>mid-size bars: 20 g, 1 oz, 50 g and 100 g,<\/li>\n<li>large bars: 10 oz, 250 g, 500 g and 1 kg,<\/li>\n<li>wholesale bars: the London Good Delivery bar of about 400 troy ounces, which private buyers rarely hold.<\/li>\n<\/ul>\n<p>A <a href=\"\/au\/glossary\/troy-ounce\/\">troy ounce<\/a> is 31.1035 grams. It is a little heavier than the ordinary ounce used for food, so a &#8220;1 oz&#8221; gold bar weighs just over 31 grams.<\/p>\n<h3>Gold bar weights in grams and ounces<\/h3>\n<p>The table below converts each common size and shows what the gold inside was worth at the <a href=\"\/au\/glossary\/spot-price\/\">spot price<\/a> on 11 November 2026, when one troy ounce of gold cost A$5,871.94.<\/p>\n<figure class=\"mrf-table\">\n<table>\n<thead>\n<tr>\n<th>Bar size<\/th>\n<th>Weight in grams<\/th>\n<th>Weight in troy ounces<\/th>\n<th>Gold value at spot (AUD)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>1 g<\/td>\n<td>1<\/td>\n<td>0.032<\/td>\n<td>A$188.79<\/td>\n<\/tr>\n<tr>\n<td>2 g<\/td>\n<td>2<\/td>\n<td>0.064<\/td>\n<td>A$377.57<\/td>\n<\/tr>\n<tr>\n<td>5 g<\/td>\n<td>5<\/td>\n<td>0.161<\/td>\n<td>A$943.94<\/td>\n<\/tr>\n<tr>\n<td>10 g<\/td>\n<td>10<\/td>\n<td>0.322<\/td>\n<td>A$1,887.87<\/td>\n<\/tr>\n<tr>\n<td>20 g<\/td>\n<td>20<\/td>\n<td>0.643<\/td>\n<td>A$3,775.75<\/td>\n<\/tr>\n<tr>\n<td>1 oz<\/td>\n<td>31.10<\/td>\n<td>1<\/td>\n<td>A$5,871.94<\/td>\n<\/tr>\n<tr>\n<td>50 g<\/td>\n<td>50<\/td>\n<td>1.608<\/td>\n<td>A$9,439.36<\/td>\n<\/tr>\n<tr>\n<td>100 g<\/td>\n<td>100<\/td>\n<td>3.215<\/td>\n<td>A$18,878.73<\/td>\n<\/tr>\n<tr>\n<td>10 oz<\/td>\n<td>311.03<\/td>\n<td>10<\/td>\n<td>A$58,719.40<\/td>\n<\/tr>\n<tr>\n<td>250 g<\/td>\n<td>250<\/td>\n<td>8.038<\/td>\n<td>A$47,196.81<\/td>\n<\/tr>\n<tr>\n<td>500 g<\/td>\n<td>500<\/td>\n<td>16.075<\/td>\n<td>A$94,393.63<\/td>\n<\/tr>\n<tr>\n<td>1 kg<\/td>\n<td>1,000<\/td>\n<td>32.151<\/td>\n<td>A$188,787.25<\/td>\n<\/tr>\n<tr>\n<td>Good Delivery bar<\/td>\n<td>about 12,440<\/td>\n<td>about 400<\/td>\n<td>about A$2.35 million<\/td>\n<\/tr>\n<\/tbody>\n<\/table><figcaption>Source: Metals Radar price service, AUD gold spot price, 11 November 2026.

When people picture &#8220;a gold bar&#8221;, they often think of the large bars stacked in central bank vaults. Those are London Good Delivery bars. According to the <a href=\"https:\/\/www.lbma.org.uk\/good-delivery\/about-good-delivery\" rel=\"noopener\" target=\"_blank\">London Bullion Market Association<\/a>, a Good Delivery gold bar contains approximately 400 troy ounces, which is roughly 12.4 kg.<\/p>\n<p>These bars trade between banks and large institutions in the wholesale market. They sit behind the global spot price, but you will almost never buy one at a retail dealer. Our glossary entry on <a href=\"\/au\/glossary\/lbma-good-delivery\/\">LBMA Good Delivery<\/a> explains how refiners get on the list.<\/p>\n<p>For a private buyer in Australia, the heaviest bar on a dealer&#8217;s shelf is usually 1 kg. It weighs about the same as a litre of water, yet it is small enough to fit in your palm, because gold is very dense.<\/p>\n<h3>Standard gold bar weight for retail buyers<\/h3>\n<p>There is no single standard size for private investors. Two sizes stand out in our price comparison, though: 1 oz and 1 kg. The 1 oz bar matches the way gold is priced worldwide. The 1 kg bar is the cheapest way to hold a lot of gold in one piece.<\/p>\n<h2>Minted Bars vs Cast Bars<\/h2>\n<p>Before you compare sizes, it helps to know that bars are made in two ways. The method affects the look of the bar and, often, the price.<\/p>\n<ul>\n<li><strong>Minted bars:<\/strong> cut from a flat strip of gold and struck with a die, like a coin. They have sharp edges, a polished finish and often a design on the front. Most small bars from 1 g to 20 g are minted.<\/li>\n<li><strong>Cast bars:<\/strong> made by pouring molten gold into a mould. They have softer edges and a rougher surface, and they need less work to produce. Larger bars, such as 250 g and 1 kg, are usually cast.<\/li>\n<\/ul>\n<p>Minted bars usually come sealed in a card with a serial number. Cast bars are often sold loose or in a simple bag. Does that matter for you? Only a little. Both types are the same pure gold, and the weight and fineness stamped on the bar are what a buyer checks when you sell.<\/p>\n<p>The Perth Mint, owned by the Government of Western Australia, makes both kinds. In our data on 11 November 2026, its Kangaroo minted bars covered 1 g, 5 g and 20 g, while its 1 oz bar was cast.<\/p>\n<h2>Gold Bar Prices by Size: Our Data<\/h2>\n<p>The <a href=\"\/au\/glossary\/premium-over-spot\/\">premium over spot<\/a> is the extra you pay above the value of the gold itself. It covers refining, minting, packaging, the dealer&#8217;s costs and margin. The formula is simple:<\/p>\n<ul>\n<li>Premium % = (price of the bar \u2212 spot value of its gold) \u00f7 spot value \u00d7 100<\/li>\n<li>Example, 1 g bar on 11 November 2026: (A$234.85 \u2212 A$188.79) \u00f7 A$188.79 \u00d7 100 = 24.4%<\/li>\n<\/ul>\n<p>To make the comparison fair, the table below uses bars from a single dealer, Australian Bullion Company, all checked on the same day. We add the Perth Mint&#8217;s own online prices where it sells the same size.<\/p>\n<figure class=\"mrf-table\">\n<table>\n<thead>\n<tr>\n<th>Bar<\/th>\n<th>Price (AUD)<\/th>\n<th>Price per gram<\/th>\n<th>Premium over spot<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>1 g Perth Mint Kangaroo minted bar (Australian Bullion Company)<\/td>\n<td>A$234.85<\/td>\n<td>A$234.85<\/td>\n<td>24.4%<\/td>\n<\/tr>\n<tr>\n<td>1 g Perth Mint Kangaroo minted bar (Perth Mint)<\/td>\n<td>A$234.89<\/td>\n<td>A$234.89<\/td>\n<td>24.4%<\/td>\n<\/tr>\n<tr>\n<td>5 g Perth Mint Kangaroo minted bar (Australian Bullion Company)<\/td>\n<td>A$1,030.00<\/td>\n<td>A$206.00<\/td>\n<td>9.1%<\/td>\n<\/tr>\n<tr>\n<td>20 g Perth Mint Kangaroo minted bar (Australian Bullion Company)<\/td>\n<td>A$3,957.00<\/td>\n<td>A$197.85<\/td>\n<td>4.8%<\/td>\n<\/tr>\n<tr>\n<td>20 g Perth Mint Kangaroo minted bar (Perth Mint)<\/td>\n<td>A$3,950.58<\/td>\n<td>A$197.53<\/td>\n<td>4.6%<\/td>\n<\/tr>\n<tr>\n<td>1 oz Perth Mint minted bar (Australian Bullion Company)<\/td>\n<td>A$6,083.00<\/td>\n<td>A$195.57<\/td>\n<td>3.6%<\/td>\n<\/tr>\n<tr>\n<td>1 oz Perth Mint cast bar (Perth Mint)<\/td>\n<td>A$6,079.02<\/td>\n<td>A$195.45<\/td>\n<td>3.5%<\/td>\n<\/tr>\n<tr>\n<td>250 g ABC cast bar (Australian Bullion Company)<\/td>\n<td>A$49,283.00<\/td>\n<td>A$197.13<\/td>\n<td>4.4%<\/td>\n<\/tr>\n<tr>\n<td>1 kg ABC cast bar (Australian Bullion Company)<\/td>\n<td>A$193,331.00<\/td>\n<td>A$193.33<\/td>\n<td>2.4%<\/td>\n<\/tr>\n<tr>\n<td>1 kg GBA cast bar (Australian Bullion Company)<\/td>\n<td>A$193,159.00<\/td>\n<td>A$193.16<\/td>\n<td>2.3%<\/td>\n<\/tr>\n<\/tbody>\n<\/table><figcaption>Source: Metals Radar price service, Australian dealer offers checked on 11 November 2026, prices before delivery.

Premium calculated by Metals Radar against the AUD gold spot price of the same day.<\/figcaption><\/figure>\n<h3>Why the 250 g bar was not the cheapest<\/h3>\n<p>You might expect the premium to fall smoothly as bars get bigger. It did not. The 250 g bar carried a premium of 4.4%, higher than the 1 oz bar at 3.6% and almost the same as the 20 g bar.<\/p>\n<p>Why would that happen? Premiums depend on demand and stock for each product, not only on weight. A popular size that a dealer sells in volume can be priced tighter than a less common size. That is why it pays to compare each size on the day you buy, rather than assume the largest bar you can afford is always the best deal.<\/p>\n<h3>What about divisible CombiBars?<\/h3>\n<p>A CombiBar is a thin bar scored into 1 g pieces that you can snap apart. It sounds like the best of both worlds: one purchase, many small units. The price says otherwise. On 11 November 2026, KJC Gold &amp; Silver Bullion listed Valcambi CombiBars at these premiums:<\/p>\n<ul>\n<li>20 g CombiBar (20 \u00d7 1 g): A$4,329.22, about 14.7% above spot,<\/li>\n<li>50 g CombiBar (50 \u00d7 1 g): A$10,509.59, about 11.3% above spot,<\/li>\n<li>100 g CombiBar (100 \u00d7 1 g): A$20,987.04, about 11.2% above spot,<\/li>\n<li>1 oz CombiBar (10 \u00d7 1\/10 oz): A$6,612.85, about 12.6% above spot.<\/li>\n<\/ul>\n<p>That is two to three times the premium of a solid bar of the same weight. A CombiBar can make sense if you value the option to break off small pieces, but you pay well for that option.<\/p>\n<h2>What 100 Grams of Gold Costs in Different Bar Sizes<\/h2>\n<p>So how much does size matter in real dollars? Let&#8217;s say you want to own 100 grams of gold. The gold itself was worth A$18,878.73 at spot on 11 November 2026.

What changes is the amount at stake, and how flexible you are when you need cash.<\/p>\n<h2>Which Gold Bar Size Should You Buy?<\/h2>\n<p>There is no single best size. The right bar balances three things: the premium you pay, the amount you can afford, and how easily you can sell part of your holding later. Here is a simple guide:<\/p>\n<figure class=\"mrf-table\">\n<table>\n<thead>\n<tr>\n<th>Size<\/th>\n<th>Who it suits<\/th>\n<th>Pros<\/th>\n<th>Cons<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>1 g to 5 g<\/td>\n<td>Gifts, first purchases, very small budgets<\/td>\n<td>Low entry price, easy to sell one at a time<\/td>\n<td>Premium of about 9% to 24% before delivery<\/td>\n<\/tr>\n<tr>\n<td>20 g to 1 oz<\/td>\n<td>Regular savers and most new investors<\/td>\n<td>Premium below 5%, still easy to sell in parts<\/td>\n<td>Each bar costs about A$4,000 to A$6,100<\/td>\n<\/tr>\n<tr>\n<td>50 g to 250 g<\/td>\n<td>Investors adding larger amounts<\/td>\n<td>Fewer bars to store and track<\/td>\n<td>Premium is not always lower than 1 oz<\/td>\n<\/tr>\n<tr>\n<td>1 kg<\/td>\n<td>Experienced buyers with a large budget<\/td>\n<td>Lowest premium per gram in our data<\/td>\n<td>You can only sell the whole bar, close to A$190,000 at a time<\/td>\n<\/tr>\n<\/tbody>\n<\/table><figcaption>Source: Metals Radar, based on Australian dealer offers and AUD spot prices, 11 November 2026.<\/figcaption><\/figure>\n<p><strong>Choose small bars if:<\/strong><\/p>\n<ul>\n<li>you want to buy a little gold each month and cannot wait to save for a larger bar,<\/li>\n<li>you want a gift that carries real gold value,<\/li>\n<li>you accept paying a higher price per gram for that flexibility.<\/li>\n<\/ul>\n<p><strong>Choose 1 oz to 1 kg bars if:<\/strong><\/p>\n<ul>\n<li>you want as much gold as possible for your money,<\/li>\n<li>you plan to hold for years and do not expect to sell small parts,<\/li>\n<li>you have safe storage, at home or in a vault.<\/li>\n<\/ul>\n<h3>A mixed approach works for many buyers<\/h3>\n<p>Many investors split their holding across sizes. For example, the core of a holding sits in 1 oz or larger bars, with a few 5 g or 10 g bars on top. If you ever need a small amount of cash, you sell a small bar and leave the rest alone.<\/p>\n<p>Prefer coins? Australian Kangaroo gold coins come in weights including 1\/10 oz, 1\/4 oz, 1\/2 oz and 1 oz, and Australian dealers trade them widely. Compare them in our guide to the <a href=\"\/au\/blog\/what-are-the-best-gold-coins-to-buy\/\">best gold coins to buy in Australia<\/a>.<\/p>\n<h2>Is There GST on Gold Bars in Australia?<\/h2>\n<p>No, not on investment gold. Under GST law, gold of at least 99.5% fineness in an investment form, such as a bar from a recognised refiner, counts as precious metal. The ATO explains the rules in its ruling on precious metals (<a href=\"https:\/\/www.ato.gov.au\/law\/view\/document?docid=GST\/GSTR200310\/NAT\/ATO\/00001\" rel=\"noopener\" target=\"_blank\">GSTR 2003\/10<\/a>). A dealer&#8217;s sale of investment gold to you carries no GST, whatever the size of the bar.<\/p>\n<p>So a 1 g bar and a 1 kg bar are taxed the same way when you buy. The size difference you pay comes from the premium, not from tax. Gold jewellery is different and does attract GST. Our glossary entry on <a href=\"\/au\/glossary\/gst-on-gold\/\">GST on gold<\/a> covers the details, and the <a href=\"\/au\/glossary\/fineness\/\">fineness<\/a> entry explains how purity is measured. For your own situation, check with the ATO or a registered tax agent.<\/p>\n<h2>Storing and Selling Bars of Different Sizes<\/h2>\n<p>Size affects what happens after you buy, too. A few practical points:<\/p>\n<ul>\n<li>small bars in sealed cards should stay sealed, because a damaged card can make a dealer look more closely before buying,<\/li>\n<li>a 1 kg bar is compact, so storage space is rarely the problem, but insurance and safe limits may be,<\/li>\n<li>when you sell, a dealer usually pays a price linked to spot, and the gap between the buy and sell price is called the <a href=\"\/au\/glossary\/bid-ask-spread\/\">bid-ask spread<\/a>,<\/li>\n<li>keep any certificate or receipt that came with a large bar, as it helps the buyer confirm what you are selling.<\/li>\n<\/ul>\n<p>For more on keeping gold safe at home or in a vault, read our guide on <a href=\"\/au\/blog\/what-is-the-proper-way-to-store-gold-top-tips-for-safe-keeping\/\">the proper way to store gold<\/a>.<\/p>\n<h2>Summary: Gold Bar Sizes in Australia<\/h2>\n<figure class=\"mrf-table\">\n<table>\n<thead>\n<tr>\n<th>Question<\/th>\n<th>Answer (11 November 2026)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Most common retail sizes<\/td>\n<td>1 g, 5 g, 20 g, 1 oz, 100 g, 250 g, 1 kg<\/td>\n<\/tr>\n<tr>\n<td>Weight of a 1 oz bar<\/td>\n<td>31.1035 g<\/td>\n<\/tr>\n<tr>\n<td>Weight of a Good Delivery bar<\/td>\n<td>About 400 troy ounces (roughly 12.4 kg)<\/td>\n<\/tr>\n<tr>\n<td>Premium on a 1 g bar<\/td>\n<td>24.4% (A$234.85)<\/td>\n<\/tr>\n<tr>\n<td>Premium on a 1 oz bar<\/td>\n<td>3.5% to 3.6% (A$6,079.02 to A$6,083.00)<\/td>\n<\/tr>\n<tr>\n<td>Premium on a 1 kg bar<\/td>\n<td>2.3% to 2.4% (A$193,159 to A$193,331)<\/td>\n<\/tr>\n<tr>\n<td>GST on investment gold bars<\/td>\n<td>None, at 99.5% fineness or higher<\/td>\n<\/tr>\n<\/tbody>\n<\/table><figcaption>Sources: Metals Radar price service (Australian dealer offers and AUD spot price, 11 November 2026); LBMA (Good Delivery bar weight); ATO GSTR 2003\/10 (GST on precious metals).<\/figcaption><\/figure>\n<h2>FAQ: Gold Bar Sizes<\/h2>\n<h3>What sizes do gold bars come in?<\/h3>\n<p>Gold bars for private buyers in Australia come in sizes from 1 g up to 1 kg. The most common are 1 g, 5 g, 10 g, 20 g, 1 oz, 50 g, 100 g, 250 g and 1 kg, with some dealers also selling 2 g, 10 oz and 500 g bars.<\/p>\n<h3>How much does a gold bar weigh?<\/h3>\n<p>A retail gold bar weighs whatever is stamped on it, from 1 g to 1 kg. The large bars held by central banks are London Good Delivery bars of approximately 400 troy ounces, which is roughly 12.4 kg.<\/p>\n<h3>How much is a 1 kg gold bar worth in Australia?<\/h3>\n<p>The gold in a 1 kg bar was worth A$188,787.25 at spot on 11 November 2026. Dealers listed 1 kg cast bars at A$193,159 to A$193,331 that day, before delivery.<\/p>\n<h3>What is the best size gold bar to buy?<\/h3>\n<p>For many Australian buyers, 20 g to 1 oz bars are the best balance. In our data, they carried premiums below 5% while staying small enough to sell one at a time.<\/p>\n<h3>Are small gold bars a bad investment?<\/h3>\n<p>No, small gold bars are not a bad investment, but they are an expensive way to buy gold. A 1 g bar cost about 24% above spot on 11 November 2026, so the gold price has to rise a long way before you break even.<\/p>\n<h3>Is a 1 oz gold bar the same weight as a 1 oz coin?<\/h3>\n<p>Yes, a 1 oz gold bar and a 1 oz bullion coin both contain one troy ounce of fine gold, which is 31.1035 g. Some coins weigh a little more in total because they are made from a gold alloy.<\/p>\n<h3>Do larger gold bars have a lower premium?<\/h3>\n<p>Yes, larger bars usually have a lower premium per gram, but not at every step. In our data, a 1 kg bar was 2.4% above spot, while a 250 g bar from the same dealer was 4.4%, above the 1 oz bar at 3.6%.<\/p>\n<h2>Compare Gold Bar Prices Before You Buy<\/h2>\n<p>The premium on each size changes from day to day and from dealer to dealer. That is why we track Australian dealer prices daily and show them side by side, so you can see which size gives you the most gold for your money before you buy.<\/p>\n<p>Start with the sizes that fit your budget: <a href=\"\/au\/categories\/1-gram-gold-bars\/\">1 g gold bars<\/a>, <a href=\"\/au\/categories\/5-gram-gold-bars\/\">5 g gold bars<\/a>, <a href=\"\/au\/categories\/20-gram-gold-bars\/\">20 g gold bars<\/a>, <a href=\"\/au\/categories\/1-oz-gold-bars\/\">1 oz gold bars<\/a>, <a href=\"\/au\/categories\/100-gram-gold-bars\/\">100 g gold bars<\/a> and <a href=\"\/au\/categories\/1-kilo-gold-bars\/\">1 kg gold bars<\/a>.
