ETF Basics: Your Portfolio’s Best Friend

Published: 6 Sep 2025 · 5–6 min read

Quick take: ETFs let you buy a basket of investments in one trade. They’re popular with Australians because they’re simple, low-cost, and broadly diversified.

What is an ETF?

An exchange-traded fund (ETF) is a fund you can buy on the ASX like a share. Each ETF holds many underlying investments (for example, hundreds of companies). When you buy one unit, you get a tiny slice of all those holdings.

Why do many investors start with ETFs?

  • Diversification: One purchase spreads your money across many companies or bonds.
  • Cost: Management fees are usually low compared to traditional funds.
  • Convenience: Buy and sell during market hours via your broker.
  • Clarity: ETFs publish what they hold and their ongoing fees.

Common ETF types you’ll see

  • Broad market: Tracks a wide index (e.g., Australian or global shares).
  • Sector or theme: Focuses on a narrower slice (e.g., technology).
  • Bond: Holds government or corporate bonds.
  • Dividend-focused: Targets income-paying companies.

Fees, in plain English

The main ongoing cost is the management fee (MER). It’s shown as a yearly percentage. For example, 0.10% means $10 per $10,000 per year. Check the ETF’s page or factsheet for the MER and any other costs.

How to compare simple options

  • What does it hold? Australia-only, global developed markets, or a mix.
  • Total cost: Look at the MER and your broker’s trading fee.
  • Size & trading: Larger funds usually have tighter buy/sell spreads.
  • Distribution style: Some funds pay distributions; others may reinvest.

A sensible first step approach

Many beginners start by picking one broad ETF and making small, regular contributions. That keeps things simple and helps avoid over-complicating the early days.

Optional: Crypto (Bitcoin/Ethereum) sleeve

  • Some investors add a small allocation to BTC or ETH either directly or via a crypto ETF alongside their core ETFs.
  • We’ll cover the pros/cons of direct ownership vs crypto ETFs (and why platform/exchange tokens are higher risk) in a later guide.
