Steps to start investing in shares in Australia

Step 1: Set your goal and time horizon

Are you investing for a house deposit in three years, retirement in thirty, or just to learn how markets work? Your timeframe shapes almost everything else that follows. Shorter horizons generally call for more caution, since there's less time to ride out a downturn, while longer horizons can absorb more short-term volatility in exchange for potentially higher long-term returns.

Writing your goal down — even just a sentence — makes the choices in the rest of this guide easier, because "what should I buy" is really a downstream question of "what am I investing for and when do I need the money."

Step 2: Decide how hands-on you want to be

Some investors want to research and pick individual companies — reading annual reports, comparing sectors, and deciding when to buy and sell. Others prefer a diversified ETF that tracks an index, like the ASX 200, with far less ongoing decision-making once the initial purchase is made.

Neither approach is inherently "better". They differ in diversification, control, costs and the amount of research a person may need to do. This guide describes those differences rather than selecting an approach for the reader.

Step 3: Compare brokers and micro-investing services

Full-service online brokers and micro-investing services can differ in ownership structure, available investments, order control, minimums, automation and fees. Some services let users select individual securities and order conditions; others use managed or pooled portfolios with different fee structures.

When comparing these services, check the ownership model, available investments, brokerage or management fees, minimums, automation features and transfer rules. Those factual differences are more useful than treating either service type as universally suitable.

Step 4: Open and fund your account

This is the mechanical step covered in full in our companion guide — how to open an online share trading account — which walks through ID verification, linking a bank account, and choosing between a HIN and custodian model. It typically takes 10–20 minutes to apply, with verification completed anywhere from the same day to a few business days.

Step 5: Make your first purchase

A first purchase involves choosing an order type, quantity and price conditions, then reviewing brokerage and settlement details before submission. Trading Guide does not suggest an amount or security; the purpose here is to explain the mechanics.

Step 6: Understand concentration and diversification

Holding a single company creates greater exposure to that company's performance. Diversification spreads exposure across multiple holdings or sectors and can reduce concentration risk, but it does not prevent losses or guarantee smoother returns.

Step 7: Understand regular investing

Investing a fixed amount on a regular schedule is commonly called dollar-cost averaging. It spreads purchases across different dates and prices. It does not guarantee a lower average purchase price, protect against falling markets, or make regular investing preferable to a lump-sum approach.

Tax basics every new investor should know

Selling or otherwise disposing of shares can create a capital gains tax (CGT) event. Australian resident individuals may be eligible for the CGT discount when the relevant conditions are met, including generally holding the asset for at least 12 months. Tax outcomes depend on individual circumstances.

Franked dividends may include franking credits reflecting tax already paid by the company. How those credits and any capital gains affect a person's tax position depends on their circumstances. Keep transaction and income records and use ATO guidance or professional tax advice where needed.
