Why some methods don't work in casinos

Legal background in Australia

Online casinos are prohibited. The country has a direct ban on the provision of online casinos (slots, roulette, poker machines). ACMA blocks sites that offer such services. Therefore, many familiar payment methods are simply not supported for Australians.
Licensed bookmakers. Sports betting and horse racing are allowed. Credit cards and cryptocurrencies have been banned for them since June 11, 2024; only debit cards, PayID and bank transfers remain.

Main reasons for unavailability of methods

1. Legal restrictions

Credit cards. The use of credit cards for online betting is prohibited. Even if the card is technically working, the transaction is blocked by the bank or operator.
Cryptocurrencies. Prohibited in the legal segment of rates. Casinos promising BTC/ETH reception operate offshore and are not protected by Australian laws.
PayPal. It is practically not used for casinos - the service limits payment for offshore gambling.

2. MCC codes and bank filters

All gambling transactions are marked MCC 7995. Many banks and fintech services block this code completely or impose limits on amounts.
Even multicurrency cards (Wise, Revolut) can reject transactions if they are associated with MCC 7995.

3. Payment systems and wallets policy

Apple Pay and Google Pay only work in conjunction with debit cards. If the card is prohibited for betting, the wallet will not work either.
Skrill/Neteller. Offshore casinos accept them, but in Australia it is risky: increased commissions, strict AML control, possible blocking.
PayPal. As a rule, it works only in the segment of licensed bookmakers, and not in casinos.

4. Limits and technical reasons

Banks and wallets impose limits on daily/weekly transactions. An attempt to transfer a large amount may be blocked until the identity is confirmed.
AML/CTF checks. With atypical or too large deposits/outputs, the operator can demand documents on the origin of funds and suspend the transaction.
DCC and international conversions. An attempt to pay in the "wrong currency" may be rejected by the system or incur an additional fee.

5. ACMA locks

ACMA maintains a blacklist of offshore sites. Even if the payment method is allowed, the site itself may be blocked. In this case, the transaction will fail.

How to act player

Use debit cards and PayID for legal rates.
Check bank limits per MCC 7995.
Not trying to pay the casino through a credit card or cryptocurrency - this will not work and may lead to blocking the account.
For large amounts, prepare proof of source of funds (AML/CTF).
Checking whether the operator supports 3-D Secure 2 increases the chance of successful authorization.

Conclusion

Some methods do not work in casinos in Australia due to a combination of factors: legislative bans (credit cards, crypto, casino sites), restrictions on MCC 7995, the policy of the payment systems themselves and bank limits. Debit cards, PayID/NPP and bank transfers remain in the legal field. Everything else is either blocked or available only on offshore sites with high risk.
