If you are certain that you want to close your CDIA, visit our step-by-step guide on how you can close your CommBank account for more information.
Please note: If the CDIA account was linked to your CommSec trading account as a settlement account, you will need to advise CommSec of a new CommBank bank account that you wish to have all future settlements debited/credited from.
Alternatively, you can contact CommSec on 13 15 19 or +61 8397 1206 if calling from overseas (Monday to Friday, 8am to 6pm, Sydney time).
