If you've looked into opening a CommSec Share Trading Account, you may have come across the Commonwealth Direct Investment Account (CDIA).
We've taken a deep dive into what it is, pros and cons of the account and how it compares with our own cash account.
Our verdict
The CDIA is the preferred cash account for CommSec and can be used to settle trades with low brokerage and no ongoing fees.
In simple terms, it's a straightforward cash account that can be used to fund your CommSec trades without having to move your money in and out of a trading account.
If you're an existing CommSec share trading account holder, or looking to apply, you can open a CDIA account at no cost.
Even if you hold an account with another bank, transferring funds to CommSec CDIA for the purposes of trading is little effort and can save you a lot on brokerage fees.
If you prefer to keep funds sitting in another account, you'll just need to ensure you have enough cash in the CDIA should you want to have the freedom of placing trades at a moment's notice.
Also through CommSec, you can use CommBank's ATM network and the NetBank online banking system to access your CDIA account. You can also enjoy unlimited electronic transactions.
Good for
If you settle your share trades directly through your CommSec CDIA account, then you'll pay as little as $5.00 per trade as opposed to $29.95 per trade.
Balances are automatically recognised by CommSec so when you see a trading opportunity, you won't have to worry about transferring funds first.
CommSec offers a free dividend direction service for CDIA account holders, meaning that they'll be automatically paid into your account where you can start earning interest immediately.
User-friendly platform and app that takes just minutes to set up.
There are no subscription or account keeping fees on the CDIA account.
Not so great for
One more bank account. While you have to fund your share trading somehow, if you're not already a member of the Commonwealth Bank, then an extra account is a hassle.
Interest rates aren't particularly competitive.
What is a CDIA account?
The Commonwealth Direct Investment Account (CDIA) is much like any other transaction account except that it’s designed to let you trade shares via CommSec. In order to settle trades via an online share trading platform, you’re required to have a linked cash management account. You could use any transaction account for this purpose, but the CDIA gives you a few key benefits.
Here are its main functions:
Buy and sell shares. After transferring funds into the CDIA account, you can use it to trade shares and store any additional cash.
Transact. Like any other cash account, you can use the CDIA to make everyday transactions, and you can access your cash via an ATM through an optional Debit Mastercard.
"I've had a CommSec CDIA account for around 7 years now and I use it to fund trades made in my CommSec Share Trading Account and CommSec Pocket account. It gives me a much lower brokerage fee than I'd get otherwise and it's easy to set up regular transfers to align with my regular investments. "

What are the benefits of using the CDIA?
Low trading fees. The main highlight of using the CDIA to trade shares through CommSec is the cheaper brokerage fees. If you buy shares using the CDIA account, you’re charged a brokerage fee of as little as $5, compared to $29.95.
Earn interest. In addition to cheaper shares, you'll be able to earn interest on cash in your account, though the rates aren't particularly competitive.
The rate you receive will increase based on the amount you have in your account, with the highest rate offered to accounts with $500,000 or more.

Online banking. If you already have a CommBank account, your Commsec CDIA account will appear in your main Internet banking window, making it easy to transact between accounts online.
Transaction account. The CDIA has an alternate function as an everyday transaction account, with the option of a debit Mastercard, making it all the more functional. Interest on cash in the account is calculated daily and paid monthly.
How do the fees differ
The biggest difference between using the CommSec CDIA account and another account is the brokerage fees. Here’s a breakdown of the brokerage fees that you can expect when using the CDIA versus using your own account.

What fees can you expect from a CommSec CDIA account?
There are no monthly fees for CDIA accounts linked to the CommSec Share Trading Account and there are unlimited fee-free electronic withdrawals.

What are the pros and cons of using a CDIA account as opposed to your own cash account?

Hi Will,
thanks for the question.
There are a number of differences between these two options. As the Commsec website states, trading with your own cash account means trades start at $29.95, whereas trading with the CDIA has costs which start at $19.95. The CDIA also presents a streamlined option by allowing you to earn interest between investments on balances of over $10,000 without the requirement of transferring funds between the difference accounts you might have.
I hope this helps,
Marc.
