Three Australian banks - NAB, ANZ and Westpac - publish a gambling block their own customers can switch on. Each bank's page is quoted below: how the block is turned on, who can turn it on, and how long it takes to come off again.
What each bank publishes
NAB

ANZ
If you'd like more control over the types of transactions your eligible card can make, you can use the ANZ App to apply a gambling block on your eligible card. Once turned on, you won't be able to make Gambling Transactions disclaimer using your digital wallet or physical card - whether the transaction is online, over the phone or in person.
If you use the ANZ App to set a gambling block on your eligible card, you will not be able to make gambling transactions with that card. This will apply whether you use your physical card or digital wallet, and covers online, phone and in-person transactions.
If you have the gambling block on, you'll need to request for it to be removed in the ANZ App first. Once 48 hours has passed, you'll be able to return to the app to remove the block entirely. Check out the how to video here to see how .
If you have activated the gambling block, you must first request its removal in the ANZ App. After 48 hours, you can return to the app to complete the process and fully remove the block. This means there is a waiting period before the block is lifted.

What this does not settle
Three banks are quoted here from archive snapshots taken on the dates shown, and no bank was asked anything by us. Another bank may do it differently, and any of them can change its page after that date. Why a payment is declined with a block on is on the page about declined card payments.
Licence status in Australia
None of the sites on this page about bank gambling blocks names an Australian licence; each is an offshore operator as far as Australian law is concerned. The Interactive Gambling Act 2001 and the ACMA's powers under it are quoted on our law page. Amounts are quoted as each operator prints them; nothing is converted to A$.
