Self service locks

We've introduced a digital self-service gambling lock to support you if you want to take a break or stop gambling on your credit or debit card.

In a few simple steps, you can lock your card from gambling transactions via either NetBank or the CommBank App.

As an added support, once a lock is switched on, there's a 48-hour cooling-off period needed to turn it off.

How it works

The CommBank credit card gambling and cash block applies to:

• Most gambling transactions, such as TAB, online gambling sites and lottery tickets
• Other transactions we consider to be cash equivalents, such as money transfers or travellers cheques
• Money withdrawn or transferred by you or an additional cardholder at ATMs, online, or over the counter at any CommBank branch

If you ask us to apply a block, we’ll stop most cash advances and cash-equivalent transactions, including gambling transactions that come to us for authorisation.
