How to Buy Shares in Australia: A Step-by-Step Guide for First-Time Investors

🧰 What you need before you start🔗

🎯 The essential: No minimum income, no experience, no financial adviser required. Just a handful of things sorted first.

• Your Tax File Number (TFN). Not legally required, but without it the broker withholds tax on investment income at the highest marginal tax rate.
• A valid Australian bank account, to fund trades and receive sale proceeds.
• At least $500 to invest. The ASX has a minimum marketable parcel rule, your first purchase of any given share must be worth at least $500 excluding brokerage. Budget a little extra on top for brokerage fees.
• ID documents for verification, your Australian driver's licence or passport. Most platforms verify digitally in minutes.

🏦 Choosing a broker: the real decision🔗

Online (execution-only) vs full-service. Online brokers let you place your own buy and sell orders without personal advice, and charge low fees, this is what most self-directed investors use. Full-service brokers provide personalised advice and research, and charge significantly more. Unless you have a complex portfolio or genuinely want hand-holding, full-service is overkill for most people starting out.

CHESS-sponsored vs custodian model, this actually matters. When you buy through a CHESS-sponsored broker, your ownership is recorded directly in your name on the ASX's CHESS subregister, you get a HIN and are the legal owner. If the broker goes bust, the shares are yours, not the broker's asset. With a custodian model, the broker holds the shares on your behalf in a pooled account, you're a beneficial owner, not the legal registered owner, and your name doesn't appear on the share register. Neither model is illegal or inherently dangerous, but CHESS sponsorship gives you cleaner, more direct ownership. Check which model a broker uses before signing up, it's usually stated clearly in their FAQ or PDS.

Brokerage fees. Every broker charges a fee per trade, or a flat rate, or a percentage, or some combination, and these change often enough that any specific figures here would be stale within months. Compare current fee schedules directly on each broker's website before choosing, and pay attention to how the fee scales with your typical trade size. On a $1,000 trade, even a $10 fee is 1% of your investment, the smaller your trade size, the more brokerage eats into your returns, which is part of why the $500 minimum parcel rule exists.

There's more to compare than fees and ownership structure alone, FX fees on international shares, product range, and account minimums all matter too. Our broker checklist walks through the full decision if you want to weigh up your options properly before signing up.

📋 Opening your account🔗

Once you've picked a broker, opening an account takes 10 to 30 minutes online.

1. Fill in your personal details: name, address, date of birth, TFN, email.
2. ID verification: most brokers verify your driver's licence or passport digitally against government records, usually under five minutes.
3. Link your bank account: your BSB and account number, so the broker can debit funds for trades and credit sale proceeds.
4. Sign the CHESS sponsorship agreement (for CHESS-sponsored brokers), standard paperwork that gives you a HIN.
5. Deposit funds before you can trade. Some brokers let you trade on a linked account immediately, others require funds to clear first.

Account approval is usually instant or same-day, occasionally 24 to 48 hours if manual review is needed.

🖱️ Placing your first order, step by step🔗

1. Search for the company by its ASX code, a three to six letter ticker. BHP is BHP, Commonwealth Bank is CBA, Telstra is TLS. We walk through one of those end to end in how to buy CBA shares.
2. Click "Buy" to open the order screen.
3. Choose your order type. A market order executes immediately at the best available price, simple and fast, though the price can move slightly between submission and fill. A limit order sets a maximum price you're willing to pay, more control, but might not fill if the price never gets there. For large, liquid ASX stocks a market order is usually fine, for smaller companies or ETFs with wider spreads a limit order gives more price certainty. Our market order vs limit order guide works through when each one costs you.
4. Enter the number of units, not dollars. If a stock trades at $45 and you want to invest $900, enter 20 units.
5. Review and confirm: ticker, units, order type, estimated price and brokerage.
6. Wait for execution. Market orders on liquid stocks typically fill within seconds during ASX trading hours (10am to 4pm AEST, Monday to Friday).

Once your order executes, you'll receive a contract note (trade confirmation). Keep it, you'll need it for tax purposes.

⏱️ What happens after you click buy🔗

After your first trade with a CHESS-sponsored broker, you'll receive a CHESS holding statement confirming your shareholding, including your Holder Identification Number (HIN). It starts with the letter X and covers all your CHESS-sponsored holdings with that broker, one HIN regardless of how many companies or ETFs you hold. Write it down and keep it somewhere safe. If you are not sure whether your broker is CHESS-sponsored at all, our HIN, SRN and custodian guide shows how to check, and what rides on the answer.

You might also encounter a Security Reference Number (SRN) if you receive shares outside a broker transaction, such as through an employee share scheme or a company float. SRNs start with the letter I and are issuer-sponsored, registered directly with the company's share registry, one SRN per company. To sell issuer-sponsored shares, your broker must first convert them to CHESS. If you use a CHESS-sponsored broker for all your purchases, you'll deal almost exclusively with your HIN.

📊 Holding your shares🔗

Your broker's platform shows your live portfolio: holdings, current prices, total value, and unrealised gains or losses. If the companies you hold pay dividends, cash lands in your nominated bank account within a few days of the payment date, alongside a dividend statement showing the amount, any franking credits, and tax withheld if applicable. See our what is a dividend guide for how franking credits actually work.

Keep every contract note. When you sell shares for more than you paid, the profit is a capital gain added to your assessable income. Held for more than 12 months, you're eligible for a 50% CGT discount, our capital gains tax guide covers the full mechanics. Neither stamp duty nor GST applies to buying or selling ASX-listed shares, though brokerage fees do include GST.

Once you're comfortable with the ASX basics, the natural next question is whether to look beyond it. Our guide to buying international shares from Australia covers what changes when you buy shares listed overseas.
