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.
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.
