Can a bank block a transaction in an online casino

In Queensland, banks and payment systems operate under Australian federal law, including the Interactive Gambling Act 2001 (IGA) and the Anti-Money Laundering and Counter-Terrorism Financing Act 2006 (AML/CTF). These laws directly affect the ability to conduct transactions in online casinos, especially when it comes to unlicensed operators.

1. Legislative basis for blocking

IGA prohibits the provision of interactive gambling services without an Australian license.
The Australian Communications and Media Authority (ACMA) maintains a list of illegal sites and sends requests to banks and payment providers to block transactions in their favor.
AML/CTF mandates banks to monitor suspicious transfers, including large or recurring payments to offshore casinos.

2. When a bank can block a transaction

If the recipient is on the list of illegal ACMA operators;
If the transaction violates the bank's gambling-related internal policies;
If money laundering or financing of prohibited activities is suspected;
If the amount or frequency of payments causes increased attention of the financial monitoring service.

3. Queensland bank practices

Large banks (Commonwealth Bank, Westpac, NAB, ANZ) can automatically reject transactions in favour of offshore casinos, even if they are technically available.
Some banks enter a temporary block until the client confirms the purpose of the payment.
Additional fees or restrictions on the use of credit cards for bets may apply.

4. Risks for players

Blocking the deposit until it is credited to the game account;
Freezing of funds during the inspection;
Closing a bank account with regular transfers to prohibited jurisdictions;
Inability to challenge the bank's decision if it is based on compliance with federal law.

5. How to reduce the risk of blocking

Check whether the operator has an Australian license or is not blacklisted by ACMA;
Avoid frequent and large transactions to offshore operators;
Keep proof of payment.

6. Final conclusion

In Queensland, a bank has the power to block a transaction at an online casino, particularly if the operator is illegal in Australia or the transfer is suspicious under AML/CTF. For players, this means that payments to offshore casinos always carry the risk of blocking or checking.
