Options trading is the market’s most misunderstood instrument — and also one of its most flexible.
Most beginners either avoid them completely (because they sound complicated) or dive in without understanding them (because leverage sounds appealing). Both approaches cost money.
The reality is that options aren’t inherently more dangerous than shares. Used correctly, they can reduce risk, generate income, or give you exposure to a price move with a defined, limited downside. Used incorrectly — without understanding the mechanics — they expire worthless and take your premium with them.
This guide explains what options are, how they work, the terminology you need to know, and how Australian traders can access them without overcomplicating things.

What Is an Option?
An option is a contract that gives the buyer the right, but not the obligation, to buy or sell an asset at a specific price before a specific date.
That definition sounds dry, so here’s an analogy that actually makes it click.
Imagine you’re interested in buying a house listed at $800,000. You’re not ready to commit yet, but you don’t want to miss out if the price rises. You negotiate with the seller: you pay them $5,000 today for the right to buy the house at $800,000 any time in the next three months.
Two things can happen:
- The house price rises to $900,000. You exercise your option and buy it at $800,000 — saving $100,000, minus the $5,000 you paid.
- The house price drops to $720,000. You let the option expire. You’ve lost the $5,000, but that’s it — you’re not forced to buy at $800,000.
That $5,000 payment is the premium. The $800,000 price is the strike price. The three-month window is the expiry date. Options on shares work exactly the same way.
Key Options Terminology
Before going further, you need these terms. They come up constantly and they’re not interchangeable.
| Term | What It Means |
|---|---|
| Premium | The price you pay to buy an option contract |
| Strike Price | The price at which you can buy or sell the underlying asset |
| Expiry Date | The date on which the option contract expires |
| Underlying Asset | The share, index, or ETF the option is based on |
| In the Money (ITM) | The option has intrinsic value — exercising it would be profitable |
| Out of the Money (OTM) | The option has no intrinsic value at the current price |
| At the Money (ATM) | The strike price equals (or is very close to) the current price |
| Exercise | Using the option to buy or sell at the strike price |
| Expiration | The option contract ceasing to exist (either exercised or worthless) |
The Two Types of Options: Calls and Puts
Every option is either a call or a put. Everything else in options trading is built on understanding these two.
Call Options
A call option gives you the right to buy an asset at the strike price before expiry.
You buy a call when you expect the price to rise.
Example: BHP shares are trading at $45.00. You buy a call option with a strike price of $47.00 expiring in 60 days. The premium costs $1.20 per share. Each ASX option contract covers 100 shares, so the total cost is $120.
- If BHP rises to $52.00, your option is worth at least $5.00 per share. You can sell the option for a profit or exercise it to buy shares at $47.00.
- If BHP stays below $47.00 at expiry, the option expires worthless. You lose the $120 premium — and nothing more.
Your maximum loss is always capped at the premium paid. Your potential gain is theoretically unlimited as the share price rises.
Put Options
A put option gives you the right to sell an asset at the strike price before expiry.
You buy a put when you expect the price to fall.
Example: You hold 500 Commonwealth Bank (CBA) shares currently worth $130 each. You’re worried about a short-term pullback but don’t want to sell. You buy put options with a $125 strike price expiring in 45 days, paying a premium of $2.00 per share ($200 per contract).
- If CBA drops to $110, your put options are now worth at least $15 per share. The profit on the puts offsets the loss on your shares.
- If CBA rises to $140, your puts expire worthless — you’re out the premium, but your shares have increased in value.
This use of puts to protect an existing portfolio is called a protective put — one of the most practical applications of options for regular investors.
How Options Are Priced
The premium you pay for an option isn’t arbitrary. It’s made up of two components:
Intrinsic Value
This is the real, tangible value of the option if you exercised it right now.
A call option with a $47 strike price on a stock trading at $50 has $3 of intrinsic value. A call option with a $55 strike price on the same $50 stock has zero intrinsic value — it’s out of the money.
Time Value
Options also carry time value — the additional premium the market assigns because there’s still time for the price to move in your favour. An option with 90 days until expiry will have more time value than an otherwise identical option with 10 days left.
Time value decays as expiry approaches. This decay accelerates in the final weeks — a concept called theta decay or time decay. It’s one of the most important dynamics for options buyers to understand: every day that passes without the underlying moving your way, your option loses a little value.
Implied Volatility
The market’s expectation of how much the underlying asset will move also affects the premium. Higher expected volatility = higher option premiums. This is measured as implied volatility (IV).
When markets are calm, IV is low and options are cheaper. During volatile periods — earnings announcements, major economic data releases, geopolitical events — IV spikes and premiums rise significantly.
Options in Australia: The ASX and How to Access Them
ASX Exchange Traded Options (ETOs)
The ASX offers Exchange Traded Options (ETOs) on around 60 Australian companies and several indices. Popular underlying assets include CBA, BHP, ANZ, Wesfarmers, and the ASX 200 index (XJO options).
ASX ETOs are standardised contracts:
- Each contract covers 100 shares
- Expiry dates are typically monthly (third Thursday of the month)
- They’re cash settled or physically settled depending on the contract
Requirements to Trade Options in Australia
Options trading in Australia requires approval from your broker — it’s not switched on by default. Most platforms require you to complete an options knowledge assessment and agree to additional risk disclosures.
ASIC classifies options as complex financial products under the Corporations Act 2001. Brokers must assess whether options are appropriate for you based on your experience and financial situation.
This isn’t bureaucracy for its own sake. Options traded without understanding the mechanics of expiry, time decay, and leverage genuinely can lose 100% of the investment in a short timeframe.
Brokers Offering Options Trading in Australia
Not all trading platforms offer options access. Some brokers that do include:
| Broker | Options Available | Notes |
|---|---|---|
| CommSec | ASX ETOs | Commonwealth Bank’s trading platform — widely used |
| nabtrade | ASX ETOs | National Australia Bank’s platform |
| Interactive Brokers | ASX ETOs + US options | Strong choice for advanced traders |
| Saxo Markets | ASX ETOs + global options | Multi-market access |
US options (on platforms like Interactive Brokers) give access to a much deeper, more liquid options market — but also introduce currency risk and additional complexity for Australian traders.
Basic Options Strategies for Beginners
Options strategies range from simple single-leg trades to complex multi-leg structures. Start with these three before moving to anything else.
1. Buying a Call (Bullish Speculation)
The simplest options strategy. You pay a premium for the right to buy shares at the strike price. You profit if the share rises above your strike + premium before expiry.
- Best for: Traders who expect a share to rise and want leveraged exposure with capped downside.
- Risk: Maximum loss = premium paid.
2. Buying a Put (Bearish Speculation or Portfolio Protection)
You pay a premium for the right to sell shares at the strike price. Profits if the share falls below strike − premium.
- Best for: Traders expecting a drop, or investors wanting to protect existing holdings.
- Risk: Maximum loss = premium paid.
3. Covered Call (Income Generation)
You own shares and sell call options against them. You collect the premium upfront. If the shares rise above the strike price, they get called away (sold at the strike). If they don’t, you keep the premium and repeat.
This is one of the most conservative options strategies — you’re not speculating, you’re generating income from shares you already hold.
Example: You own 500 BHP shares at $44.00. You sell call options at a $46.00 strike for $0.80 per share, collecting $400. If BHP stays below $46.00, you keep $400 and can repeat next month. If BHP rises above $46.00, your shares are sold at $46 — you still profit from the capital gain plus the premium.
Risk: You cap your upside on the shares. If BHP rockets to $55, you still only receive $46.
| Strategy | Outlook | Max Loss | Max Gain | Complexity |
|---|---|---|---|---|
| Buy Call | Bullish | Premium paid | Unlimited | Low |
| Buy Put | Bearish | Premium paid | Strike − Premium | Low |
| Covered Call | Neutral–Bullish | Share price drop | Premium + share gain to strike | Low–Moderate |
| Protective Put | Neutral–Bearish | Premium paid | Unlimited upside on shares | Low–Moderate |
| Bull Call Spread | Moderately Bullish | Net premium paid | Difference in strikes − premium | Moderate |
Key Risks Every Beginner Must Understand
Options Can Expire Worthless
Unlike shares, options have an expiry date. If you buy a call option and the share price doesn’t move above your strike before expiry, the option expires worthless. You lose the entire premium — 100% of what you invested in that contract.
This happens more often than beginners expect. Timing matters in a way it doesn’t with shares.
Time Decay Works Against Buyers
Every day that passes erodes the time value in your option. If you buy a call and the share goes nowhere for three weeks, your option will be worth less than when you bought it — even if the share price hasn’t changed.
Options buyers need the underlying to move in the right direction, by enough, fast enough. That’s three conditions, not one.
Leverage Amplifies Losses Too
A 5% rise in BHP shares might make your call option worth 50% more. But a 5% fall can make it worth 60% less — or worthless, if it pushes it out of the money close to expiry.
Assignment Risk for Sellers
If you’re selling options (as in a covered call), there’s a risk of early assignment — the buyer exercises their right before expiry. This is more relevant on US-style options (exercisable at any time) than on ASX ETOs (which are mostly European-style, exercisable only at expiry). But it’s worth understanding before you sell.
| Factor | Options | Shares | CFDs |
|---|---|---|---|
| Ownership of asset | No (right only) | Yes | No |
| Maximum loss (buying) | Premium paid | Full investment | Full margin |
| Leverage | Yes (built-in) | No (unless on margin) | Yes |
| Expiry date | Yes | No | No (but overnight fees) |
| Income generation | Yes (selling options) | Yes (dividends) | No |
| Complexity | High | Low | Medium |
| Available on ASX | Yes (ETOs) | Yes | Via CFD brokers |
Practical Tips Before You Trade Options
Paper trade first.
Most platforms allow you to simulate options trades before using real money. Run 10–15 paper trades across different strategies to understand how premiums change as the share price and expiry date move.
Start with liquid underlyings.
CBA, BHP, ANZ — high-volume stocks with active options markets and tighter spreads. Illiquid options on small-cap stocks have wide bid-ask spreads that eat into returns before the trade even starts.
Understand your breakeven before entering.
For a call option, breakeven = strike price + premium paid. For a put, breakeven = strike price − premium paid. If the share doesn’t reach your breakeven before expiry, you lose money. Know this number before you buy.
Don’t sell naked options as a beginner.
Selling uncovered (naked) call options — where you don’t own the underlying shares — carries theoretically unlimited risk. ASIC and most Australian brokers require significant account size and experience before allowing this.
Conclusion
Options trading has a steeper learning curve than buying shares, but the mechanics are learnable and the applications are genuinely useful — from hedging a portfolio to generating income from shares you already hold.
The mistake most beginners make is treating options like lottery tickets: buy a cheap out-of-the-money call before an earnings announcement and hope it explodes. Sometimes it works. More often, the option expires worthless, and the lesson is an expensive one.
The traders who use options well treat them as a tool with specific jobs: protecting downside, generating premium income, or getting defined-risk exposure to a move. That framing — options as a tool, not a shortcut — is worth holding onto before you place your first contract.
Frequently Asked Questions
Can beginners trade options in Australia?
Yes, but brokers require you to pass a knowledge assessment before options trading is enabled on your account. ASIC classifies options as complex financial products, so platforms are required to verify that you understand the risks. Starting with paper trading before using real money is strongly recommended.
What is the minimum amount needed to trade options in Australia?
ASX option contracts cover 100 shares. For a stock trading at $40 with a $0.60 premium, one contract costs $60 plus brokerage. In practice, most brokers charge a minimum brokerage of $10–$20 per options trade, so small contracts can be expensive relative to the premium paid. A realistic starting amount is $1,000–$2,000 AUD.
What happens if an option expires worthless?
If your option is out of the money at expiry, it expires worthless. The premium you paid is lost entirely. No further action is required — the contract simply ceases to exist. This is the maximum loss for an option buyer and is why understanding your breakeven price before entering is essential.
Options are generally treated as capital assets by the ATO. Premiums paid for options that expire worthless are a capital loss. Profits from selling options are capital gains. Options used in a business context (frequent trading) may be treated as ordinary income. The tax treatment can be complex — particularly for multi-leg strategies — and a tax accountant familiar with derivatives is useful if you trade options regularly.
What is the difference between ASX options and US options?
ASX Exchange Traded Options (ETOs) cover around 60 Australian companies and are mostly European-style (exercisable only at expiry). US options are American-style (exercisable at any time before expiry), available on thousands of stocks, and have significantly deeper liquidity. Australian traders can access US options through brokers like Interactive Brokers, but currency conversion and additional regulatory considerations apply.
