Yes, you can.
Once your account has been established and verified, Macquarie will send you a separate email which includes your banking and login details for Macquarie. You will need to set up your login and password on the Macquarie portal after receiving this email.
At any time, you can access their portal and manage your Macquarie CMA (your AUD wallet) directly from there.
If you already have a Macquarie Bank account, you will be able to see your account with your existing login and move money between these two accounts instantly!
