How to Invest in the ASX: A Beginner's Guide for Australians

This guide walks you through how to invest in the ASX in plain English: what the exchange actually is, how it works, and the practical steps to go from "I've never bought a share" to placing your first trade with confidence.

A quick note before we begin: this is general information, not personal advice, and investing carries risk, including the possibility of losing money. The goal here is to help you understand your options so you can make informed decisions that suit your own circumstances.

What is the ASX?

The ASX (Australian Securities Exchange) is Australia's primary marketplace for buying and selling shares. When a company "lists" on the ASX, everyday investors can buy small units of ownership in it — and later sell them to other investors.

You'll often hear the market's performance described through an index. The best known is the S&P/ASX 200, which tracks the 200 largest companies listed on the exchange and is widely used as a snapshot of how the Australian share market is travelling. Listed companies are grouped into sectors — financials, materials and resources, healthcare, technology, consumer goods and more — which is useful when you're thinking about spreading your money around.

The ASX is one of the world's larger share markets, and shares can also be traded on Cboe Australia, a second local exchange. For most beginners, though, "investing in the ASX" simply means buying Australian-listed shares and funds through an online broker.

What can you invest in on the ASX?

The ASX isn't only individual company shares. Common options include:

• Shares — direct ownership in a single company (for example, a major bank or miner).

• Exchange-traded funds (ETFs) — a single investment that holds a basket of many shares, giving you instant diversification. If you're new to these, our beginner's guide to ETFs breaks them down.

• Listed investment companies (LICs) — companies whose business is investing in other companies on your behalf.

• A-REITs — listed property trusts that let you invest in property portfolios without buying a building.

How the ASX works

A few mechanics are worth understanding before you place a trade:

• Trading hours. The ASX runs normal trading from 10:00am to 4:00pm Sydney time, Monday to Friday (excluding public holidays), with a pre-open period beforehand where orders can be queued.

• Ticker codes. Every listed company has a short code — for example, BHP or CBA — which you'll use to find and trade it.

• Settlement (T+2). When you buy shares, the trade officially "settles" two business days later. This is handled electronically behind the scenes.

What is CHESS sponsorship and a HIN?

Here's a detail that genuinely matters and is often glossed over: how your shares are held.

ASX shares can be CHESS-sponsored, which means they're registered under your own Holder Identification Number (HIN) — a unique number tied to you. In practice, this means you hold direct legal ownership of your shares in your own name, rather than a broker holding them on your behalf in a pooled account.

The alternative model used by some platforms is custodial, where the broker (or a custodian) is the registered holder and you have a beneficial interest. Both are legitimate structures, but they differ in how ownership, record-keeping and portability work. If a platform is CHESS-sponsored, moving your shares or verifying ownership tends to be more straightforward.

Selfwealth uses the HIN-based, CHESS-sponsored model for ASX shares, so investors hold their Australian shares directly. (Note: CHESS applies to ASX-listed securities only — US and other international shares are held under different arrangements through a broker's international partner.)

How to invest in the ASX, step by step

1. Set your goals and timeframe

Before choosing anything, get clear on why you're investing and for how long. Are you investing for a goal that's five, ten or twenty years away? Shares can rise and fall in the short term, so many people treat them as a long-term commitment. Your timeframe and comfort with risk shape everything that follows. ASIC's Moneysmart has a helpful, unbiased overview in its guide to buying and selling shares.

2. Choose a broker

To buy ASX shares, you trade through a broker — a licensed business that places your orders on the market. When comparing brokers, look at:

• Brokerage (the fee per trade) — some charge a flat fee, others a percentage of the trade value.

• Ownership model — CHESS-sponsored (HIN) versus custodial.

• Markets available — ASX only, or ASX plus US and other exchanges.

• Tools and research — order types, live pricing, and educational content.

• Ongoing fees — some platforms charge account-keeping or inactivity fees.

Selfwealth, for example, offers flat $9.50 brokerage on ASX and US trades with no account-keeping fees, and Australian shares are held directly under your HIN. You can compare the details on the pricing page. Whichever broker you choose, make sure it's licensed and that you understand exactly what you'll pay.

3. Open and verify your account

Opening an account is usually an online process that takes a few minutes, followed by identity verification (a legal requirement for all Australian brokers). You'll also choose an account type:

• Individual — held in your name.

• Joint — shared between two people, such as a couple.

• Company, trust, or SMSF — for business, family-trust or self-managed super fund investing.

The structure you pick has tax and estate implications, so if you're unsure which suits you, a registered tax agent or licensed adviser can help.

4. Fund your account

Once your account is open, you transfer money in before you can trade. Common options are:

• Osko — near-instant transfers between Australian bank accounts.

• Standard bank transfer — usually clears in 1–2 business days.

Only invest money you won't need in the near term, and keep an emergency buffer separate from your investments.

5. Choose what to buy

Now the interesting part. Two common starting points for beginners are:

• Individual shares in established companies you understand.

• ETFs, which spread your money across many companies in a single trade — a popular, low-effort way to diversify.

Do your own research rather than buying on a tip or headline. Company annual reports and the ASX website are good starting points, and Moneysmart's choosing shares to buy is a solid neutral resource.

One practical detail: the first time you buy a particular ASX stock, there's generally a minimum marketable parcel of $500 (excluding brokerage). After that first purchase, you can usually top up with smaller amounts. If you're starting small, here's how to start investing with just $500.

6. Place your first trade

To buy, search for the company or ETF by name or ticker code, decide how much to invest, and choose your order type:

• Market order — buys at the best available price right now.

• Limit order — only buys at or below the maximum price you set.

Then review and confirm. For a full walkthrough with screenshots of the process, see how to buy your first stock. Prefer a broader primer on the whole journey? Our how to buy shares in Australia guide covers it end to end.

7. Track and manage your portfolio

Once you own shares, keep an eye on your holdings, stay informed about company announcements, and avoid reacting emotionally to every market wobble. Many long-term investors check in periodically and rebalance occasionally, rather than trading constantly.

Shares vs ETFs on the ASX

For beginners, this is often the key decision:

• Individual shares give you targeted exposure to a single company and full control, but concentrate your risk in one business. If it does poorly, so does that part of your portfolio.

• ETFs hold many companies at once, so a single trade can give you broad diversification — which is why they're so popular with new investors. In exchange, you pay a small ongoing management fee to the fund and give up the ability to hand-pick each holding.

Neither is "better" universally; they suit different goals. Many investors use a mix — an ETF core for diversification, with a few individual shares alongside.

What does it cost to invest in the ASX?

Costs eat into returns, so it pays to understand them:

• Brokerage is the main cost. Flat-fee brokers charge the same amount regardless of trade size; percentage-based brokers charge a proportion of what you invest. As an illustration, a flat $9.50 fee stays $9.50 whether you invest $1,000 or $50,000, whereas a hypothetical 0.10% fee would be $50 on a $50,000 trade. Flat fees tend to favour larger trades; small, frequent trades can rack up costs on any model.

• FX conversion fees apply if you trade international (non-ASX) shares.

• Ongoing platform fees — check for account-keeping or inactivity charges.

There's also tax to consider. If you sell shares for a profit, you may have a capital gain, and dividends are generally taxable too. Tax is specific to your circumstances, so this isn't tax advice — speak with a registered tax agent or read ASIC's Moneysmart for general guidance.

Managing risk and staying consistent

Investing in shares always carries risk: prices can fall as well as rise, dividends aren't guaranteed, and you can get back less than you put in. No structure or feature — flat fees, CHESS sponsorship or scheduled investing — removes that risk. A few widely used principles can help you manage it:

• Diversify across companies and sectors so no single holding sinks your portfolio.

• Think long term and try not to react to short-term noise.

• Invest regularly. Rather than trying to time the market, many investors contribute a set amount on a schedule — an approach called dollar-cost averaging. Selfwealth's Auto-Invest feature can automate recurring buy orders into a chosen share or ETF each week, fortnight or month.

Remember that past performance is not a reliable indicator of future returns — a strong recent run for a share, ETF or the market as a whole doesn't guarantee what happens next.

Common beginner mistakes

• Investing money you might need soon.

• Not comparing brokerage before choosing a platform — small fees add up over many trades.

• Buying on a tip or headline without doing your own research.

• Not understanding how your shares are held (CHESS-sponsored vs custodial).

• Trying to time the market instead of investing with a long-term view.

Frequently asked questions

How much money do I need to start investing in the ASX? 

The first time you buy a particular ASX stock, there's generally a minimum marketable parcel of $500 (excluding brokerage). After that, you can usually add smaller amounts. The ASX has generally suggested starting with at least around $2,000, but the right amount depends on your goals and budget.

Do I own my shares directly on the ASX? 

It depends on the platform. With a CHESS-sponsored broker, your ASX shares are registered under your own Holder Identification Number (HIN), giving you direct legal ownership. Some platforms instead use a custodial model, where the broker holds the shares on your behalf. CHESS applies to ASX-listed securities only.

What's the difference between shares and ETFs? 

A share is ownership in a single company. An ETF holds a basket of many companies in one investment, giving you instant diversification. Shares offer targeted control; ETFs spread risk for a small ongoing fee. Many beginners start with ETFs or use a mix of both.

How much does it cost to trade ASX shares? 

The main cost is brokerage — a fee per trade. Flat-fee brokers charge the same amount on any trade size (for example, $9.50), while others charge a percentage. Watch also for account-keeping fees, and FX fees if you trade international shares. Selling at a profit may also have tax implications.

When is the ASX open? 

Normal trading runs from 10:00am to 4:00pm Sydney time, Monday to Friday, excluding public holidays, with a pre-open period beforehand.

Is investing in the ASX safe? 

No investment is risk-free. Share prices can rise and fall, and you can lose money. You can manage risk through diversification, a long-term approach and regular investing, but you can't eliminate it. Consider your own situation and seek licensed advice if you're unsure.
