How to Buy Stocks in Australia: Beginner's Guide

Buying your first stock in Australia takes about 15 minutes. You open an account with an online broker, transfer money in, search for a stock or ETF, and place an order. The process is mechanical. The decisions around what to buy, when to buy, and how much to invest require more thought.

This guide covers the full process: choosing a broker, setting up your account, buying ASX-listed shares, investing in the S&P 500 from Australia, and handling tax obligations. Each step names specific platforms, fees, and numbers so you can act on the information.

Australian investors can choose from local brokers (CommSec, Stake, SelfWealth, Pearler) and international platforms (Interactive Brokers, eToro). Each broker charges different brokerage fees, offers different market access, and provides different research tools. Your choice depends on where you want to invest and how much you plan to trade.

For ASX shares alone, CommSec and SelfWealth dominate the market. CommSec charges $5 per trade up to $1,000 and $10 for trades between $1,000 and $10,000. SelfWealth charges a flat $9.50 per ASX trade regardless of trade size. Stake offers $3 brokerage on ASX trades, the cheapest among established brokers. Pearler charges $5.50 per trade and targets long-term investors with automated recurring investment features.

For US shares and international markets, Stake and Interactive Brokers stand out. Stake charges $0 brokerage on US trades (the company makes money on the currency conversion spread of about 0.7%). Interactive Brokers charges USD $1 per trade and offers the tightest FX spread at around 0.2%. If you plan to invest $10,000 or more in US shares per year, the FX savings on Interactive Brokers outweigh Stake's $0 brokerage.

Pick your broker based on where you want to invest. If you plan to buy ASX shares and ASX-listed ETFs, CommSec or Stake will do. If you want direct access to US stocks like Apple, Tesla, or Nvidia, use Stake or Interactive Brokers. CommSec charges US$19.95 per US trade, which makes it expensive for frequent international trading. Experienced traders who want faster execution can explore day trading strategies and platform selection.

Every broker requires identity verification before you trade. You provide your name, date of birth, address, tax file number (TFN), and a photo ID (driver's licence or passport). Most brokers verify your identity within 24 hours using electronic checks against government databases. Some brokers, like Interactive Brokers, require additional documentation for non-Australian citizens.

Providing your TFN is optional but recommended. Without a TFN on file, your broker withholds tax at the highest marginal rate (47%) on any dividends you receive. With a TFN, dividends get paid without withholding, and you declare them in your annual tax return at your actual marginal rate. If you want to diversify beyond stocks, our guide on investing in commodities covers gold, oil, and agricultural exposure.

When your ASX trading account activates, the broker registers you with CHESS (Clearing House Electronic Subregister System). CHESS assigns you a HIN (Holder Identification Number), a 10-digit code starting with "X" that identifies your share holdings. Your HIN links your shares to you, not to the broker. If your broker collapses, your shares stay in your name under your HIN. This structure protected investors when brokerages like Halifax and BBY collapsed.

Some brokers use a custodian model instead of CHESS sponsorship. Under this model, the broker holds shares on your behalf in a pooled account. eToro uses the custodian model for Australian users. Custodian-held shares do not give you a personal HIN. If the broker fails, recovering your shares becomes more complex because you need to prove your beneficial ownership within the pooled account. CHESS-sponsored brokers (CommSec, SelfWealth, Stake) give you direct ownership from day one.

Transfer money into your brokerage account via bank transfer (PayID, BPAY, or direct deposit). PayID transfers arrive within minutes. BPAY takes 1 to 2 business days. Direct deposits from a linked bank account settle within a few hours at most brokers. Most brokers do not accept credit card funding.

With funds in your account, search for the stock or ETF you want to buy. Every ASX-listed security has a 3-letter ticker code. BHP Group is BHP. Commonwealth Bank is CBA. The Vanguard Australian Shares ETF is VAS. The iShares S&P 500 ETF is IVV. Type the ticker into your broker's search bar and the security's current price and order book will appear.

You place either a market order or a limit order. A market order buys at the current asking price. A limit order lets you set the maximum price you will pay. For liquid stocks like CBA or BHP, market orders fill within seconds at a price close to what you see on screen. For smaller companies with lower trading volumes, use limit orders to avoid paying more than you intended. The spread between the bid and ask price on a low-volume stock can reach 2% to 5%.

ASX trades settle on a T+2 basis: the shares appear in your CHESS holding two business days after the trade executes. Your broker deducts the purchase amount plus brokerage from your cash balance on trade day. You own the shares from the moment the trade executes, even though settlement takes two days. You can sell the shares before settlement completes if needed.

The S&P 500 tracks 500 of the largest US companies by market capitalisation. Apple, Microsoft, Amazon, Nvidia, and Alphabet make up the top five holdings. The index has returned an average of 10.2% per year over the past 30 years, including the dot-com crash, the GFC, and the COVID sell-off. Australian investors can access the S&P 500 through two routes. If you want to explore more active strategies, our options trading guide covers leveraged instruments on the ASX.

The first route: buy an ASX-listed ETF that tracks the S&P 500. iShares S&P 500 ETF (ticker: IVV on the ASX) holds all 500 stocks and charges a management fee of 0.04% per year. On a $10,000 investment, that fee costs $4 per year. BetaShares S&P 500 Equal Weight ETF (QUS) offers an equal-weight version at 0.34% per year, which gives smaller companies in the index more influence on your returns.

Buying IVV on the ASX costs you AUD brokerage ($3 to $10 depending on your broker) and avoids currency conversion fees. The ETF manager (BlackRock) handles the USD exposure internally. You buy in Australian dollars and sell in Australian dollars. Currency movements between AUD and USD affect your returns: a falling AUD boosts your IVV returns in AUD terms, while a rising AUD drags them down.

The second route: open a US trading account (Stake or Interactive Brokers) and buy VOO or SPY on the NYSE. Vanguard S&P 500 ETF (VOO) charges 0.03% per year. SPDR S&P 500 ETF (SPY) charges 0.095%. This path requires converting AUD to USD, which costs 0.5% to 0.7% on most platforms. You gain direct access to the US market, US dividend payments in USD, and the ability to buy individual US stocks alongside your S&P 500 ETF.

For most beginners, buying IVV on the ASX through CommSec or Stake is the simplest path to S&P 500 exposure. You avoid foreign exchange hassle, file all your tax in Australian dollars, and receive dividend distributions in AUD. Once your portfolio grows past $50,000, the FX savings on Interactive Brokers may justify opening a US brokerage account and buying VOO.

The ATO taxes share investment income in two ways: dividends and capital gains. Understanding both matters before you buy your first share.

Australian companies pay franked dividends. Franking credits represent tax the company has paid on its profits before distributing them to shareholders. If CBA pays a $2.50 per share dividend, fully franked, you receive $2.50 in cash plus a franking credit of about $1.07. You declare the grossed-up amount ($3.57) as income on your tax return and claim the $1.07 as a tax offset. If your marginal tax rate is below the 30% company tax rate, the ATO refunds the excess credit. A shareholder earning under $18,200 per year receives the full franking credit as a cash refund.

US dividends arrive without franking credits. The US government withholds 15% tax on dividends paid to Australian residents (under the Australia-US tax treaty). You claim a Foreign Income Tax Offset (FITO) on your Australian tax return to avoid double taxation. Your broker should issue a CHESS or custodian statement showing the withholding amount. Without the FITO claim, you pay tax twice on the same income.

Capital gains tax (CGT) applies when you sell shares for more than you paid. If you hold the shares for more than 12 months, you receive a 50% CGT discount. A $10,000 profit on shares held for 13 months counts as $5,000 of assessable income. Shares held for less than 12 months attract CGT on the full gain at your marginal tax rate. This discount incentivises long-term holding and penalises frequent trading.

Your broker provides an annual tax statement summarising dividends, franking credits, and capital gains events. Services like Sharesight ($19/month for up to 10 holdings) automate CGT calculations across multiple brokers and generate ATO-compatible reports. If you hold shares across CommSec and Stake, Sharesight consolidates both into a single tax report.

Buying individual stocks before understanding diversification tops the list. A single company can drop 30% in a week on a bad earnings report. Qantas fell 11% in one session in August 2023 after reporting weak forward bookings. An index ETF like VAS (ASX 300) or IVV (S&P 500) spreads your money across hundreds of companies. One stock crashes, but the rest hold your portfolio together.

Checking your portfolio every day causes unnecessary anxiety. Share prices move up and down each session. A new investor who watches their $5,000 investment drop to $4,800 in the first week may panic-sell at a loss. That same investment, left alone for five years, has strong odds of growing. Vanguard data shows that Australian investors who checked their portfolio less than once a month earned higher returns than daily checkers, because they avoided emotional selling.

Ignoring brokerage costs on small trades erodes returns. A $5 brokerage fee on a $200 trade represents 2.5% of your investment. You need a 2.5% gain before you break even. If you invest less than $500 per trade, use a low-brokerage platform like Stake ($3 per trade) or set up a recurring investment through Pearler to reduce per-trade costs. Pearler lets you automate fortnightly investments into a chosen ETF, which also removes the temptation to time the market.

Failing to keep records creates tax headaches. Record the date, price, brokerage fee, and number of shares for every trade you make. The ATO requires you to calculate capital gains on a per-parcel basis. If you bought 50 CBA shares in January and 30 CBA shares in March, those are two separate parcels with different cost bases. Selling 40 shares later requires you to specify which parcel you sold from. Your broker tracks this, but you should verify the records.
