Your cash account for trading.

The Commonwealth Direct Investment Account (CDIA) is the preferred cash management account for CommSec share traders - with it you can seamlessly settle trades, transact and earn tiered interest based on your account balance.

Your CDIA is linked to your CommSec Trading Account so you enjoy low brokerage costs plus the convenience of settling trades without the need to transfer between accounts. The tiered interest rate applies to the entire balance on your account (including dividends paid into this account), pay no monthly account-keeping fee, enjoy unlimited electronic withdrawals¹ and complete access to your cash anytime.

How it works

The CDIA is the preferred cash management account for CommSec, allowing you to seamlessly settle trades, save and transact all from one account. Your CDIA is linked to your CommSec Trading Account for settlement of your trades. You can access your account online through NetBank and CommSec.

When you’re not using your cash for investments, it could be earning interest, calculated daily and paid monthly. There are no account keeping fees, and you’ll get unlimited free electronic transactions.

Access your cash from any CBA branch, ATM, or via phone and internet banking.
Settle your trades automatically through your CDIA.
Earn tiered interest on funds in your account.
Use the optional Debit MasterCard to access your cash globally.
