How does CommSec work?

CommSec's online tools let you research and trade listed securities, including Australian shares. You can view real-time share prices, market information and research data for free. Brokerage fees when you buy and sell start from $19.95. Share trades can be paid for either through an existing bank account or through a Commonwealth Direct Investment Account (CDIA).

  • Single login. You can log in through CommSec or NetBank and switch between the two, with access to your trades and your CDIA.
  • Consolidated statements. Receive one statement containing all of your activity for each account, which makes it simpler to track and manage your cash.
  • News and research. You can keep up-to-date with the latest share market news and reports, videos, stock prices and trends, including daily reports on key financial events compiled by CommSec analysts.
  • Trade in international shares and ETFs. CommSec allows you to invest in businesses and brands that are internationally recognised, such as Apple or Google. Exchange traded funds (ETFs) also provide access to government bonds and other market sectors. A fast-growing investment product in the US, EFTs are funds that trade on a stock exchange, just like ordinary shares. You can use ETFs for cost-effective, easy access to markets and asset classes you might not otherwise have access to, such as debt, derivatives, currency and commodities.
  • Mobile app. Manage and monitor your investments, trade and stay on top of the market on the go with the free CommSec Mobile App, available through the iPhone App Store or Google Play.

Settlement account: Commonwealth Direct Investment Account (CDIA)

The Commonwealth Direct Investment Account (CDIA) is designed as a settlement account to allow easy share trading with a low per-trade brokerage fee, as well as functioning as an everyday transaction account, with an option of a debit Mastercard. Earn interest on your money between investments, so there is no need to move money from one account to another.

Interest is calculated daily and paid monthly, with no account keeping fees. You can use CommBank's ATM network and NetBank online banking. You can also enjoy unlimited electronic transactions and two assisted withdrawals each month.

What types of products does CommSec offer?

investment_loan_currentlsrInternational share trading

CommSec gives you access to over 25 leading global share markets including the New York Stock Exchange and London Stock Exchange. It has a partnership with Pershing LLC, a subsidiary of the Bank of New York Mellon that provides access to both US and non-US markets. You'll need to contact CommSec to transfer funds into the relevant currency on your account.

Contract for differences (CFDs)

The CFD is an over-the-counter (OTC) contract between you an CommSec, who is the CFD issuer. CommSec provides more than 7,000 different types of CFDs, from international shares to global indices. CFD trades start from as little as $10. There are a range of rates you'll need consider: commission and spreads, funding costs, currency conversion, borrowing charges and indicative margins.

Margin lending

Available for customers who are over 18 and are an individual, company, or trust; a CommSec Margin Loan is a flexible way of borrowing money for your investment strategy. You choose how much to borrow, when to drawn down funds from your loan and whether you prefer a fixed or variable interest rate.

If the market falls, your portfolio’s value may also fall below your loan balance. If at any time your gearing level is greater than the Margin Call Ratio or the Maximum Gearing Ratio, a margin call will be triggered. This is why it’s so important to keep in touch with the market by regularly checking updates and alerts, or with an account manager from CommSec.

Options trading

Exchange Traded Options come in two types: Call options (the right to buy) and Put Options (the right to sell). Commsec charges a range of fees depending on the type of option you purchase and how you trade it.

CommSec offers an option for clients to process a one-off trade if they have an issuer sponsored holding they wish to trade without opening a full CommSec trading account. You will be required to fill out a form regarding your trade (available from the CommSec website), and mail it to CommSec marking it with attention to 'One Off Trades'. You will need to pay a brokerage fee of $65 per trade up to $10,000 or 0.66% of the value of the trade if it is greater than $10,000, which will be deducted from the profits of the trade.

    I am new to share trading, 20 years ago I was successful share trading then got a caught then give it away. I was using software that i could setup a list of companies I wish to watch then activate a purchase by phone or computer then set predetermined margins and predetermined loss by percentage to buy and sell stock.
    Do you know if the ComSecc software offers these functions?

      Hi Jeff,

      Thanks for your question.

      The CommSec Mobile App does allow you to trade on the go and to set up a Watchlist. While I can’t be too sure that the features are exactly the same, the CommBank Mobile App comes with features to help you trade direct from your smartphone. Please remember, we are a comparison website and can provide general advice only.

      Hi George,

      Thank you for your inquiry. Just to confirm though that you’ve come through to – we are a financial comparison website and we are not an affiliate of Commonwealth Bank.

      CommSecIRESS works on a flexible month-by-month subscription service for regular traders, where if you trade 8 or more times (or incur $220 or more in brokerage) in a subscribed month, CommSec waives the subscription fee. But please note that the standard subscription does not include any additional services such as Standard International Markets, Premium International Markets and Domestic Markets, which are also excluded from free access and will be charged separately.

      For more details about CommSecIRESS and fees, please refer to the CommSec page I sent to your email.

    I am just about to open a CommSec account. I currently own a portfolio of shares. Can I sell them via my CommSec account and can I view the progress of my current shares through my CommSec account?

    • Staff
      ClarizzaJuly 7, 2016Staff

      Hi Todd,

      Thanks for your question.

      To sell your current portfolio of shares, you need to transfer the shares to your Commsec account (if they are currently with another broker) and then sell it from there.

      Hope this helps.

    I have and use a Comsec share trading account but don’t know how to buy an IPO before they become listed. Personally I would prefer to arrange this through Comsec if there is a way.

    Question: Can I do this through Comsec or do I need to contact the listing company direct to do this?

    • Staff
      ShirleyMarch 9, 2015Staff

      Hi Nick,

      Thanks for your question.

      To invest an in IPO you need to complete an application form that can be found in a prospectus and this can usually be obtained from your broker.

      It’s best to speak to Commsec first to see if they can facilitate this investment for you.

      Hi Julie,

      Thanks for your question.

      Once you’ve opened a CommSec Trading account, it can be up and running in a little as five minutes. You can use your own funds to pay for the shares, the funds will need to be transferred into your cash account for this.

      Please note that Commsec is a share trading platform and that a Commsec Share broker will be doing the actual trades for you.

      The process is different depending on the type of trade that you’d like to execute. The Commsec website has this handy guide for new clients.

      Hi David,

      Thanks for your question.

      The process to transfer your shares across to Commsec is possible but will be a long process (at least several weeks).

      You’ll need to complete the Form Equiniti sent you, with Commsec’s Crest details (Commsec can provide you the relevant details once your International Trading account is setup). Commsec will get the form stamped by Pershing (their external provider for International Trading) and then send back to Equiniti for processing.

      Please also be advised you may be charged a fee of obtaining the form from Equiniti.
