Hi there, Lauren.

Commonwealth Bank of Australia (CBA) does not currently support Direct Feeds for credit card accounts in QuickBooks Online Australia.

Only the Business and Personal bank accounts are supported by CBA Direct Feeds. 

You can refer to this article for reference: Connect to Commonwealth Bank Direct Feeds.

Additionally, CBA Standard Feeds, which support credit card connections, are currently unavailable.

Please also consider checking this article: The QuickBooks Online bank connection status page.

 You can also manually upload your bank transactions for your new credit card account. 

If you have additional concerns, don’t hesitate to leave a comment below.
