How to Invest in Shares for Beginners in Australia

By Roopon Team7 min read

Understanding What You're Buying

Before opening a brokerage account, understanding what shares actually are - and what you're taking on when you buy them - builds the mental framework for better decisions.

  • A share is part ownership: When you buy a share in a company, you own a fraction of that business - its assets, earnings, and future growth. As a shareholder, you're entitled to dividends (a share of profits distributed to owners) and capital gains if you sell for more than you paid.
  • ASX: The Australian Securities Exchange (ASX) is where listed Australian companies trade. The ASX 200 (S&P/ASX 200 Index) tracks the 200 largest companies by market capitalisation - BHP, CBA, CSL, NAB, ANZ, and so on. An ETF tracking the ASX 200 gives you a piece of all 200 companies in one purchase.
  • ETFs vs individual shares: An Exchange Traded Fund (ETF) is a single listed security that holds a basket of underlying assets - an index, sector, or asset class. Buying VAS (Vanguard Australian Shares Index) gives you exposure to 300 Australian companies for the price of one unit ($90). This is how most beginners should start - diversification without complexity.
  • Market vs limit orders: A market order buys at whatever the current price is - fast but the price can move between placing and execution. A limit order only executes if the price reaches your specified level - gives price control but may not execute if the market moves away. For beginners buying ETFs, market orders during market hours are generally fine.
  • Bid-ask spread: Every listed security has a bid price (what buyers will pay) and an ask price (what sellers want). The difference is the spread - an implicit transaction cost. For highly liquid ETFs, the spread is typically 1-3 cents per unit - negligible. For illiquid small-cap stocks, spreads can be much wider.
  • Settlement: ASX trades settle T+2 - the money and shares exchange 2 business days after the trade date. You need funds in your brokerage account before buying (or in a settlement account that funds can be drawn from).

Choosing a Brokerage Account: The Options

Your choice of broker affects your costs, access to markets, and features. For most Australian beginners, one of these five platforms covers all needs.

  • CommSec: Australia's largest retail broker, owned by CBA. Flat brokerage: $10 for trades up to $1,000, $19.95 for $1,001-$10,000. Established, reliable, good research tools. Requires a CBA transaction account or standalone cash account. Best for those who want a full-service Australian broker.
  • SelfWealth: Flat $9.50 per trade regardless of size - the same cost whether you buy $500 or $50,000 of shares. Popular with DIY investors making larger or less frequent trades. No minimum balance. Offers US share trading too.
  • Stake: $3 per Australian trade (or free with a US plan). Strong mobile app, popular with younger investors. Also offers fractional US shares. Lower cost than CommSec for small trades.
  • Pearler: Specifically designed for long-term buy-and-hold investors. Flat $6.50 per trade, automatic investment plans (invest a fixed amount monthly without manual action), and a focus on ETF investing. Excellent for building the automated investing habit.
  • Superhero: $2 per ETF trade, $5 per share trade. Low-cost entry point with a clean mobile app. Also offers US shares.
  • What to compare: Brokerage fee per trade (critical for small regular investors), international market access (if you want US shares), CHESS sponsorship (CHESS-sponsored means you directly hold shares on the ASX register - custodian models mean the broker holds them on your behalf, which has different risk profiles), and mobile app quality for your usage style.

Your First Portfolio: What to Buy

For most beginners, a simple ETF-based portfolio outperforms complex alternatives. Here's a framework for building your first portfolio based on your goals and timeline.

  • Start with one or two ETFs: Complexity is the enemy of beginners. A single ETF like VDHG (Vanguard Diversified High Growth - 90% growth assets, 10% defensive, globally diversified) or DHHF (Betashares Diversified All Growth - 100% growth assets) provides instant global diversification. This is a complete portfolio in one purchase.
  • Core Australian + International split: For those who want to build their own allocation: VAS (Vanguard Australian Shares, ASX 300) + VGS (Vanguard International Shares, developed markets). A 30% VAS / 70% VGS split mirrors the Australian share market's global weight. This is widely used by DIY investors as a low-cost core.
  • Add a bond ETF for balance: If you're within 5-10 years of needing the money, adding VAF (Vanguard Australian Fixed Interest) or AGVT (government bonds) reduces volatility. For 20-30 year horizons, bonds are not necessary - growth assets deliver better long-term outcomes despite higher short-term swings.
  • What to avoid as a beginner: Individual company stocks (concentration risk), thematic or sector ETFs (narrower, higher volatility, often fee-heavy), leveraged or inverse ETFs (complex instruments that decay over time), and cryptocurrency as a primary investment (speculative, highly volatile, minimal income).
  • Minimum investment: Most ETFs have no minimum purchase beyond the unit price (~$50-$120 per unit). Some brokers have minimum trade sizes of $500 - check before selecting a platform. Pearler's auto-invest feature can build positions over time with as little as $100/month.
  • International shares (US stocks): Once comfortable with the basics, US-listed stocks and ETFs are accessible through Stake, SelfWealth, or Interactive Brokers. Complete a W-8BEN form (exempts you from US withholding tax on most income - 30% reduced to 15% under the Australia-US tax treaty). US estate tax risk applies to holdings over USD $60,000 - use Australian-listed ETFs hedging US exposure (like IHVV or HJPN) to avoid this.

Tax Rules for Australian Share Investors

Understanding the tax rules for shares before you buy saves surprises at tax time. Australia's share tax treatment is straightforward once you know the basics.

  • Capital gains tax (CGT): When you sell shares for more than you paid, the profit is a capital gain - assessable income in the year of sale. If you held the shares for at least 12 months before selling, you receive a 50% CGT discount - only half the gain is included in your taxable income. Hold for at least 12 months before selling profitable positions.
  • Capital losses: Losses on share sales can only offset capital gains - not ordinary income. Unused capital losses carry forward indefinitely to offset future gains. Don't crystallise a loss just to 'do something' - wait until there's a gain to offset.
  • Dividends and franking credits: Dividends from Australian companies are assessable income in the year received. Fully franked dividends include franking credits (representing corporate tax already paid) that reduce your personal tax. For investors on lower marginal rates, franking credits can produce a tax refund.
  • Record-keeping: Keep purchase confirmation records (contract notes) for every share purchase. Cost base = purchase price + brokerage fee. These records must be kept until 5 years after the eventual sale. Most brokers provide annual tax reports - download and save these each year.
  • Share investing and your tax return: Dividend income goes to the 'dividends' section. Capital gains go to the 'capital gains' schedule. Franking credits are entered separately as tax offsets. If you use a broker's annual tax report, most of this pre-populates correctly - but verify against your own records.
  • Wash sale rule: Australia does not have a formal wash sale rule (unlike the US). However, the ATO can apply Part IVA (general anti-avoidance) to arrangements where shares are sold and immediately repurchased solely to crystallise a tax loss. Keep genuine economic substance in your decisions.

The Best Time to Start Is Now

Every week you delay buying your first ETF is a week of compounding you never get back. The research phase is valuable - but three hours of reading is enough to make a sensible first purchase. Open the account, transfer $500, buy one diversified ETF, and set up a monthly automatic investment. The sophistication and additional research can follow. The habit comes first.
