What is Short Selling? Short Selling Explained for Australian Traders

Short selling is when you sell an asset you don’t currently own, hoping to buy it back later at a lower price and pocket the difference. Most Australian CFD brokers let you short sell shares, indices like the ASX 200, forex pairs, and commodities directly from your trading platform — no special broker arrangement required.

How Short Selling Works — A Practical Example

Say the ASX 200 is trading at 7,800 points and you believe it’s about to fall. You open a short CFD position worth A$10,000 using leverage through your broker. If the ASX 200 drops 3% to 7,566 points, your position gains A$300 — that’s the difference in value working in your favour.

But if the ASX 200 rises 3% instead, you lose A$300 on that position. Unlike buying an asset, where your maximum loss is what you paid, a short position can theoretically lose more than your initial outlay if the price keeps rising. That’s why risk management tools like stop-loss orders are critical when shorting.

Don’t forget trading costs. If you hold the short position overnight, your broker will charge a swap or overnight financing fee — typically a small daily percentage of the position value. These costs add up quickly on multi-day trades. You can use a margin calculator to estimate the capital required before you enter.

Why Short Selling Matters for Australian Traders

Short selling gives Australian traders the ability to profit — or hedge existing holdings — when markets are falling. Without it, you’d be limited to only making money when prices rise, which means sitting on the sidelines during downturns or watching losses build in a long portfolio.

ASIC regulates how CFD brokers in Australia offer short selling. Under ASIC’s product intervention orders, retail clients face leverage caps — for example, a maximum of 20:1 on major forex pairs and 10:1 on individual equities. This limits how large a short position you can take relative to your account balance, which reduces both potential gains and potential losses. Brokers holding an AFSL (Australian Financial Services Licence) are required to follow these limits, giving retail traders a meaningful layer of protection.

When a broker handles short selling well, you get clear margin requirements, transparent overnight fees, and reliable stop-loss execution. Poorly managed brokers may widen spreads during volatile markets or execute stop-losses at worse prices than expected — both of which hurt short sellers most, since sharp upward spikes are a short seller’s worst-case scenario. See our Pepperstone review for an example of how a well-regulated Australian broker handles short CFD positions.

Short Selling vs Buying Put Options

Short selling via CFDs and buying put options are both ways to profit from falling prices, but they work differently. With a short CFD, your loss is theoretically unlimited if the price rises — you stay exposed as long as the trade is open. A put option, by contrast, caps your maximum loss at the premium you paid upfront, since you simply let the option expire worthless if the market moves against you.

Put options also require understanding strike prices, expiry dates, and time decay — concepts that add complexity for newer traders. Short CFDs are simpler to execute but demand strict risk management. For most Australian traders, understanding your maximum possible loss before entering a short position is the more important factor to check.

What to Check When Comparing Brokers

• Overnight swap rates on short positions: Some brokers charge more to hold short positions overnight than long ones — always check the specific rate for the asset you plan to short, not just the headline figure.
• Margin requirements and ASIC leverage limits: Confirm the broker applies ASIC’s retail leverage caps and clearly displays how much margin you need to open and maintain a short position. Our best CFD brokers in Australia list only includes ASIC-licensed brokers that meet these standards.
• Stop-loss execution quality: Look for brokers that offer guaranteed stop-loss orders (GSLOs) if you’re shorting volatile assets — these protect you from slippage during fast-moving markets, though they usually carry a small extra fee.
• Range of shortable instruments: Not all brokers let you short every market. Check that your broker offers short CFDs on the specific assets — ASX stocks, crypto, commodities — you want to trade.
• Negative balance protection: Under ASIC rules, retail CFD clients must be protected from losing more than their account balance. Confirm this protection is in place, especially before shorting high-volatility assets like BTC. Our IC Markets review covers how this broker applies negative balance protection in practice.
