How it works

Provide your consent on the website or app of the accredited organisation you want to share your CommBank data with first. You’ll then be taken securely to CommBank so you can easily set up data sharing. Here’s a snapshot of the steps:

Enter the mobile number you’ve registered and we’ll send you a One Time Password. We may ask you for the last 4 digits of your NetBank ID to help us identify you.

Go to your notifications in the CommBank app or check your NetBank inbox and enter the password.

If you don’t receive it, call 13 2221.

Choose the accounts you’d like to share. If a joint account is enabled for data sharing, you’ll be able to select it, otherwise you’ll need to enable it first (see below).

Review the details and confirm you'd like to share. We’ll take you securely back to the accredited organisation you started on.

Enabling a joint account for data sharing 

Before you can share data from a joint account, you need to enable it and your other account holder must approve. To do so:

  1. Go to Settings, Manage data sharing then Outgoing data and select Joint account sharing preferences. Choose the joint account you want to share and enable sharing
  2. We’ll send your other joint account holder a message asking them to approve or decline your request
  3. If they approve, your joint account will be enabled and you can select it from the list of accounts eligible for data sharing (see step 3 above)

Who can share data and what accounts are available?

To be eligible for data sharing, you:

  • Must be at least 18 years old and registered for NetBank
  • Must have an eligible individual or joint account
  • Can be a sole trader    

If you’re eligible, you can now share some of your customer details, account information and transaction history for these CommBank accounts:

  • Credit cards
  • Deposit and transaction accounts
  • Offset accounts
  • Home loans and personal loans
  • Overdrafts
  • Trust accounts
  • Lines of credit 
  • Business and asset finance
  • Foreign currency accounts

We’re making more consumer data available for these products. See Data to come for details.

View or manage data sharing
