Cheapest stock brokers in Australia

Want the most affordable way to start trading shares? We've reviewed more than 70 products from over 30 online brokers in the Mozo database and found these to be the cheapest options.

Australia’s cheapest online stock brokers

In the tables below, we've consulted the Mozo database to rank share trading apps that offer trades on the ASX and do not charge monthly fees. We then categorised them based on their cost-effectiveness for either small or large trades.

One important feature to note is CHESS sponsorship. When a broker offers this, it means your shares are held directly in your name on the ASX’s official register with your own Holder Identification Number (HIN). The primary advantages are direct legal ownership and easier administration, like transferring your portfolio to another broker. On some platforms, this may be an optional feature you can choose.

What are brokerage fees?

Brokerage fees are what you pay an online trading platform when you buy or sell shares. There are several common ways these fees are structured:

  • Tiered fees. Many platforms adopt a tiered fee model, charging a flat rate for trades below a certain value and a percentage-based fee for larger trades.
  • Percentage fees. Other platforms charge a consistent percentage of the total trade value, typically with a minimum fee. This approach is straightforward and can mirror the tiered model in practice.
  • Commission-free trading. A growing number of online brokers now offer trading without brokerage fees, though they may offset these costs through premium services or advertising.

It’s also important to be aware of other potential fees like monthly charges for access to advanced tools or foreign exchange fees for trades involving non-AUD stocks.

Are there any free trading platforms in Australia?

While “free trading” may be common overseas, in Australia it can perhaps more accurately be described as “low-cost under certain conditions.” Platforms may promote $0 brokerage, but other costs often still apply. The main things to look out for are:

  • FX fees. Charged when converting AUD to buy international shares.
  • Trade limits. $0 brokerage might only apply to small trades, with standard fees kicking in once you exceed specific caps.
  • Platform or subscription fees. Some brokers charge ongoing monthly fees for access.
  • Custodial vs CHESS-sponsored. Low-cost brokers often use custodial models, meaning the broker technically holds the shares for you. With CHESS, shares are in your name, which many investors prefer.

Tips for finding the cheapest online trading app

If you don’t want excessive fees eating into your gains, you’ll want to seek out affordable options. Here are some tips to help you find the cheapest trading app that still does what you need it to:

  • Look at the brokerage fees. Most apps charge a brokerage fee, so this is the first place to look. The lower the fee, the better - provided the platform meets your trading needs.
  • Watch for extra fees. Keep an eye out for other fees like monthly fees, withdrawal fees and foreign exchange fees (for buying global stocks in AUD). Sometimes these fees pay for useful features and services, but other times they might just be a sneaky way to offset low brokerage fees.
  • Consider your trading activity. Different apps cater to different types of investors and are priced accordingly. What’s cost-effective for low volume traders might be different than what’s cost-effective for larger volume traders.
  • Search for discounts. Keep an eye out for promotional offers, like the ones listed in the next section below.

Just make sure the app you choose offers the functionality you need. There’s no point saving money on a share trading platform that doesn’t meet your needs in the first place.
