Gambling transaction blocks on credit and debit cards

Gambling and credit card photo.jpg

Several Australian banks and financial institutions have recently introduced options that allow customers to block gambling transactions on their credit and debit cards.

Upon request, a block will usually be activated immediately. The amount of time it takes to lift a block differs, but it is generally up to two business days.

The process of blocking gambling transactions on credit/debit cards varies between banks and financial institutions. In most instances, customers must make a request, but some banks and institutions offer customers the option of doing it themselves via a smartphone app.

In some cases, a block will not be ongoing. The customer must nominate the period of time they wish the block to apply before it expires.

These types of initiatives are not always actively promoted, so anyone wishing to block gambling transactions on their cards is encouraged to familiarise themselves with the relevant policies and/or to make specific enquiries of their bank or financial institution.

We have collated below information about options currently available to customers at some banks. In addition, the Foundation’s Submission to the Australian Banking Association consultation on the use of credit cards for gambling transactions is available here.
