Options Trading in Australia: Platforms and Guide

Options give you the right to buy or sell an asset at a set price before a set date. Australian traders access options on ASX-listed stocks through domestic brokers and US options through international platforms. The Australian options market is smaller than the US market, with fewer contracts and wider spreads, but it covers the major ASX 200 stocks and the XJO index.

You need an options-approved brokerage account, a clear understanding of the risks, and enough capital to cover margin requirements. This guide covers the platforms available, the costs involved, and the tax rules that apply.

The ASX lists equity options on around 60 of the most traded Australian stocks: BHP, CBA, CSL, NAB, Westpac, Telstra, Woolworths, and similar large caps. Index options trade on the S&P/ASX 200 (XJO). Each ASX equity option contract represents 100 shares. ASX options are American-style, meaning you can exercise them before expiry.

US options markets offer thousands of contracts across every sector. You can trade options on Apple, Tesla, SPY, QQQ, and hundreds of ETFs. Liquidity is far deeper, spreads are tighter, and expiry dates are more frequent (weekly options are common in the US, rare on the ASX). US equity options are also American-style. US index options (SPX, NDX) are European-style and settle in cash.

Most active Australian options traders use both markets. They trade ASX options for Australian exposure and US options for broader strategies, tighter spreads, and access to weekly expirations.

Not every Australian broker offers options trading. Many share-trading platforms (Stake, Superhero, Raiz) focus on shares and ETFs with no options capability. The brokers below all provide options access for Australian residents.

Interactive Brokers dominates for serious options traders. It offers the lowest commissions, access to both ASX and US options, professional-grade analytics (the Options Strategy Lab and Probability Lab), and portfolio margin for experienced accounts. The platform is complex. New traders find the interface steep to learn.

CommSec and the Big Four bank brokers charge $29.95 to $34.95 per ASX options trade. At that rate, multi-leg strategies (iron condors, spreads) become expensive because each leg incurs a separate commission. These platforms suit investors writing covered calls on existing share holdings, not active options traders.

Tastyworks (now tastytrade) is purpose-built for options. The platform visualizes probability of profit, expected move, and Greeks. US options cost $1.00 per contract to open and $0 to close. It does not offer ASX options. Australian residents can open accounts, fund in USD, and trade US markets.

Australian brokers require you to apply for options trading approval. The process involves a questionnaire about your trading experience, financial situation, and understanding of options risks. CommSec and the bank brokers assign approval levels: Level 1 for covered calls and cash-secured puts, Level 2 for buying calls and puts, Level 3 for spreads and advanced strategies.

Interactive Brokers assesses your experience and net worth. They grant trading permissions in tiers. New applicants with limited experience receive access to buying options and covered calls. Writing naked options requires a margin account, higher net worth thresholds, and demonstrated experience.

ASIC requires that brokers provide a Product Disclosure Statement (PDS) for exchange-traded options. You must acknowledge that you've read the ASX's "Understanding Options" booklet before trading. This is a regulatory requirement, not a formality. Options can lose 100% of their value. Writing uncovered options exposes you to losses that exceed your initial investment.

Covered calls are the starting point for most Australian options traders. You own 100 shares of BHP. You sell a call option with a strike price above the current share price. You collect the premium. If BHP stays below the strike at expiry, you keep the shares and the premium. If BHP rises above the strike, your shares get called away at the strike price. You made a profit on the shares plus the premium, but you missed the upside above the strike.

Cash-secured puts let you buy shares at a discount. You sell a put option on CBA with a strike below the current price. If CBA falls below the strike, you buy the shares at that price. If CBA stays above the strike, you keep the premium without buying shares. You need enough cash in the account to cover the purchase if the put is exercised.

Buying calls is a directional bet that a stock will rise. You pay the premium upfront. If the stock moves above the strike plus your premium by expiry, you profit. If it doesn't, you lose the entire premium. Time decay works against you. The closer to expiry, the faster the option loses value if the stock hasn't moved. Traders who prefer faster-paced strategies should also read our guide on day trading in Australia for an overview of intraday setups and risk management.

Vertical spreads cap both your risk and reward. A bull call spread involves buying a call at one strike and selling a call at a higher strike. Your maximum loss is the net premium paid. Your maximum gain is the difference between strikes minus the net premium. Spreads cost less than outright calls and reduce the impact of time decay.

The ATO treats options trading profits as either capital gains or ordinary income. The classification depends on whether you trade as an investor or as a business (carrying on a business of trading).

If you trade infrequently and hold positions for weeks or months, the ATO treats profits as capital gains. Options held for more than 12 months qualify for the 50% CGT discount. Options that expire worthless crystallise a capital loss in the financial year they expire.

If you trade as a business (frequent trades, significant capital, systematic approach, profit motive), the ATO taxes profits as ordinary income at your marginal rate. You can deduct trading-related expenses: platform fees, data subscriptions, education courses, and a portion of your home office. Business traders do not receive the 50% CGT discount.

Premiums received from writing options (covered calls, naked puts) are assessable income in the year you receive them if the option expires unexercised. If the option is exercised, the premium adjusts the cost base of the underlying shares. Keep records of every trade: date, strike, premium, expiry, and whether exercised or expired. The ATO expects detailed records for options traders.

US options profits for Australian residents attract the same treatment. You convert USD gains to AUD at the exchange rate on the date of each transaction. Foreign exchange movements between trade date and settlement date can create additional gains or losses. Use your broker's tax statement as a starting point, but verify the AUD conversion calculations.

Buying options risks 100% of the premium paid. If the stock doesn't move in your direction by enough to cover the premium before expiry, you lose the entire amount. Around 70% to 80% of options expire out of the money.

Writing (selling) uncovered options carries theoretically unlimited risk. If you sell a naked call on a stock and the price doubles, you owe the difference. Margin requirements for writing options are substantial. Interactive Brokers calculates margin in real time based on the underlying stock's volatility. CommSec requires you to post margin in advance and may issue margin calls if the position moves against you.

ASX options have less liquidity than US options. Wide bid-ask spreads on less-traded contracts mean you lose money entering and exiting positions. Stick to options on high-volume ASX stocks (BHP, CBA, CSL, NAB) where spreads are tightest. For US options, stick to high-volume underlyings (SPY, QQQ, AAPL, TSLA) for the best execution.

Start with defined-risk strategies: buying calls, buying puts, vertical spreads, and covered calls. These cap your maximum loss at the amount you invest. Graduate to undefined-risk strategies (naked puts, strangles, iron condors) after you've traded for at least six months and understand how Greeks (delta, theta, vega, gamma) affect your positions. CFD traders exploring options should read our comparison of CFDs and futures trading in Australia to understand how leverage works across different instruments.

Paper trading (simulated trading with no real money) is available on Interactive Brokers and tastytrade. Use it for at least four to eight weeks before committing capital. Track your simulated trades in a spreadsheet: entry price, exit price, profit or loss, and the rationale for each trade. If your paper trading results are negative after 50 trades, you are not ready for real money.

The ASX offers a free online course called "ASX Options" through the ASX Academy. It covers the fundamentals: call and put mechanics, payoff diagrams, time decay, and implied volatility. The Options Industry Council (OIC) in the US provides free courses for US-listed options. Both are worth completing before placing your first trade.
