21 Bit Payment Methods
Nine ways in, four ways out, A$20 to start. Here is what each one actually costs you in time and money.
Short answer
21 Bit Casino takes PayID, BPAY, bank transfer, Visa and Mastercard debit, Apple Pay, Google Pay, Neosurf, MiFinity and crypto. The minimum is A$20 on everything except crypto, which starts at A$30. The casino charges nothing at either end. PayID is the quickest way in; crypto and MiFinity are the quickest way out.
Australian players get a slightly different banking menu than the rest of the world, and it is not because the casino decided to be difficult. Credit cards were legislated out of online gambling in June 2024. POLi, which used to be the default way Australians funded a casino account, has been quietly strangled by the banks. What is left is the New Payments Platform, a handful of wallets, debit cards, and crypto — and each behaves differently enough to be worth a paragraph.
We funded and drained a real account on each rail to write this. Where we quote a time, it is the time we actually measured, not the time in the cashier's marketing copy. Where the two disagree, we say so.
Bank rails: PayID, BPAY and direct transfer
These three all move money straight from your bank account, but they run on completely different plumbing and the speed difference is enormous.
PayID — the one to use
PayID rides the New Payments Platform, the same rails as Osko. You get a PayID string in the cashier, paste it into your banking app as a new payee, send the amount, done. Every deposit we timed landed in under two minutes, including one sent at 11pm on a Sunday — the NPP does not keep banking hours.
Two things to know. First, your bank may hold your very first payment to a new PayID for up to 24 hours as a scam-protection measure; this is a one-off and only affects the first transfer. Second, PayID only works in one direction here. Withdrawals come back as a standard bank transfer to the account sitting behind that PayID, which is slower.
Minimum A$20 · No fee · Deposit only
BPAY — slow but bulletproof
BPAY gives you a biller code and a customer reference number that you enter in your banking app. Nothing about it is fast: one business day is normal, two if you pay after the afternoon cut-off or over a weekend. What it has going for it is that it almost never fails. If your card keeps bouncing and PayID is not an option, BPAY will get the money there.
Do not reuse an old reference number from a previous deposit. It is tied to a single transaction, and a reused CRN is the most common way a BPAY payment ends up unallocated for a week.
Minimum A$20 · No fee · Deposit only · 1–2 business days
Bank transfer — the payout default
Direct transfer is a mediocre way to deposit and the most common way to get paid. It is the fallback withdrawal route whenever your deposit method cannot receive money, which covers BPAY, Neosurf and PayID. Expect three to five business days end to end, with most of that sitting between the casino's payment provider and your bank rather than at the casino.
The account has to be in your own name. A joint account is fine as long as you are one of the named holders. A transfer to an account in someone else's name will be reversed at the compliance stage and you will wait another week for it to come back.
Minimum A$20 in, A$50 out · No fee · 3–5 business days
On POLi: it is still on the cashier screen, and we would still steer you away from it. Most of the big four now block POLi's bank-login flow outright, and a failed POLi attempt sometimes leaves the deposit in limbo for a day before it reverses. PayID does the identical job — instant, straight from your account, no card involved.
E-wallets, vouchers and crypto
This is where the fast withdrawals live. If getting paid quickly matters more to you than anything else, fund the account with one of these from the start, because you can generally only be paid back the way you paid in.
MiFinity
The only conventional e-wallet here that works in both directions. Deposits are instant, withdrawals were back in the wallet within four hours in our tests. Getting the money from MiFinity into an Australian bank account is a second step and adds a day.
A$20 in · A$50 out · Two-way
Apple Pay & Google Pay
Both are a wrapper around the debit card already in your phone, so they inherit the card's rules — including any gambling block your bank has applied. Instant, convenient, and deposit-only. Nice for topping up on the couch, useless for cashing out.
A$20 · Instant · Deposit only
Neosurf
A prepaid voucher you buy with cash at a newsagent or servo and redeem as a code. Genuinely useful if you want a hard ceiling on what you can spend, since you cannot deposit more than the voucher is worth. Vouchers cap out at A$500 and there is no way to be paid back to one.
A$20 · Instant · Deposit only
Crypto — BTC, ETH, LTC
The fastest payouts on the site, full stop. Litecoin confirmed in about fifteen minutes for us; Bitcoin took closer to forty when the mempool was busy. The trade-off is that the network fee is yours to pay and the AUD value is fixed at the moment of conversion, so a volatile hour can cost you more than a bank transfer would have.
A$30 in · A$50 out · Two-way · Network fee applies
Debit cards, and why your credit card will not work
Visa Debit and Mastercard Debit both work. Deposits are instant and the money leaves your transaction account immediately. Withdrawals back to a debit card take one to three business days, which is respectable but nowhere near crypto or MiFinity.
Credit cards are a different story, and the reason has nothing to do with 21 Bit. Since June 2024 it has been illegal in Australia to use a credit card, or credit-linked products like BNPL and digital currency bought on credit, to fund online gambling. Every licensed and offshore operator serving Australians has had to build the block in. If you tap a credit card into the cashier, it will be refused at the BIN check before it ever reaches your bank — the card number itself tells the processor what kind of card it is.
A card sitting in an Apple Pay or Google Pay wallet is treated exactly the same way. The wallet is not the payment instrument; the card behind it is.
Worth knowing: a debit card deposit is processed offshore, so your bank may add an international transaction fee of around 3 per cent even though the amount is billed in AUD. Bank rails and crypto do not attract it. On a A$500 deposit that is A$15 you keep by using PayID instead.
Why your payment was declined
In order of how often we see each one:
It was a credit card
Legally blocked since June 2024. Nothing you or support can do. Use a debit card, PayID or BPAY.
Your bank has a gambling block on the card
CommBank, Westpac, NAB and ANZ all let you switch gambling transactions off in the app, and some accounts ship with it on by default. It is usually under card controls or spend controls. Note the cooling-off period: switching it back off can take 48 hours by design.
The name on the card does not match the account
Third-party payments are refused at the AML stage. Your partner's card will not work on your account, even with their blessing.
You are under the A$20 minimum
A$15 will simply bounce with a generic error rather than a helpful one. A$30 if you are sending crypto.
Verification is not finished
Deposits generally still work, but larger ones trigger a hold until your ID is approved. Getting KYC done on day one avoids the whole category of problem.
Every method, side by side
Times are what we measured on a verified account in July and August 2026. First withdrawals take longer than the figures below because of the one-off KYC check.
| Method | Min | Max | Deposit speed | Fee | Withdrawal |
|---|---|---|---|---|---|
| PayID | A$20 | A$10,000 | Under 2 min | None | No — pays out by bank transfer |
| BPAY | A$20 | A$10,000 | 1–2 bus. days | None | No — pays out by bank transfer |
| Bank transfer | A$20 | A$25,000 | 1–3 bus. days | None | Yes — 3–5 business days |
| Visa Debit | A$20 | A$5,000 | Instant | None* | Yes — 1–3 business days |
| Mastercard Debit | A$20 | A$5,000 | Instant | None* | Yes — 1–3 business days |
| Apple Pay | A$20 | A$5,000 | Instant | None* | No |
| Google Pay | A$20 | A$5,000 | Instant | None* | No |
| MiFinity | A$20 | A$10,000 | Instant | None | Yes — within 4 hours |
| Neosurf | A$20 | A$500 | Instant | None | No — pays out by bank transfer |
| Bitcoin | A$30 | A$50,000 | 20–40 min | Network fee | Yes — 30–60 minutes |
| Ethereum | A$30 | A$50,000 | 10–20 min | Network fee | Yes — under 1 hour |
| Litecoin | A$30 | A$50,000 | 10–15 min | Network fee | Yes — 15–30 minutes |
* No fee from the casino. Your own bank may add an international transaction fee of roughly 3% on card payments. Maximums are per transaction; daily and monthly ceilings are higher and depend on your account tier.
What it looks like on your bank statement
It will not say 21 Bit Casino. Offshore casino payments are routed through a payment processor, and the processor's descriptor is what your bank records. In practice you will see something along the lines of a generic entertainment, media or digital services name, a city that has nothing to do with you, and a long reference number.
People notice this and assume they have been defrauded. Before you call your bank's fraud line, check the transaction history in your casino account — the amount, the timestamp and the last four digits of the card will line up. Filing a chargeback on a legitimate deposit gets your casino account frozen and is a slow, unpleasant thing to unwind.
The one part worth writing down is the reference number. If a deposit is debited but never credited, that string is what support uses to trace it. Without it you are asking someone to find one payment among thousands by the amount alone.
Bank transfers and PayID are cleaner in this respect: they show a business name and your reference, and they are easier to reconcile later. Crypto does not appear on a bank statement at all, which some players consider a feature and the ATO would remind you is not a substitute for keeping records.
Mistakes that cost people days
Depositing with a method that cannot pay out. Neosurf, BPAY, PayID, Apple Pay and Google Pay are all one-way. Your winnings then default to bank transfer at three to five days. If speed matters, deposit with crypto or MiFinity.
Leaving KYC until you want your money. Verification takes 24 to 48 hours and it runs before the withdrawal, not alongside it. Upload your ID and a recent utility bill on the day you sign up and it never costs you anything.
Cashing out with a bonus still active. Requesting a withdrawal while wagering is unmet either cancels the bonus and its winnings, or the request is simply refused. Check the bonus balance first.
Sending the wrong coin to a crypto address. Litecoin to a Bitcoin address is gone permanently and nobody can recover it. Copy the address, check the network label, send a small test amount if the sum is large.
Reusing a BPAY reference number. Each CRN belongs to one deposit. A reused one leaves the payment unallocated until someone reconciles it by hand.
What changed over the past year
The Australian payment menu has moved more in the last eighteen months than in the previous five years. This is where it stood at the start of 2025 against where it stands now.
| Then | Now |
|---|---|
| Credit cards accepted with a surcharge | Blocked outright — federal law since June 2024 |
| POLi was the default instant bank deposit | Still listed, blocked by most major banks — use PayID |
| PayID absent from the cashier | Added, and now the fastest way in |
| Crypto payouts took up to 24 hours | 15–60 minutes depending on the coin |
| Minimum withdrawal A$100 | A$50 |
| Skrill and Neteller listed for AU players | Withdrawn for this market — MiFinity replaced them |
Frequently asked questions
What payment methods does 21 Bit Casino accept in Australia?
PayID, BPAY, bank transfer, Visa Debit and Mastercard Debit, Apple Pay, Google Pay, Neosurf, MiFinity and crypto (BTC, ETH, LTC). Credit cards are not accepted for gambling deposits in Australia. The minimum deposit is A$20 on every method except crypto, which starts at A$30.
Does 21 Bit Casino accept PayID?
Yes. PayID deposits clear over the New Payments Platform and usually land in under two minutes, including outside banking hours. The minimum is A$20 and there is no fee from the casino side. PayID is deposit-only — withdrawals go back by bank transfer to the account behind your PayID.
Are there fees on deposits or withdrawals at 21 Bit Casino?
The casino does not charge a fee on any AUD method. Crypto deposits and withdrawals carry the network fee, which varies with congestion. Your own bank may apply an international transaction fee on card deposits, typically around 3 per cent, because the payment is processed offshore.
Why was my deposit declined at 21 Bit Casino?
The three usual causes are a credit card (blocked by Australian law since June 2024), a bank-level gambling block on your debit card, or a mismatch between your account name and the card holder name. Switch to PayID or BPAY, or ask your bank to lift the gambling block, and the payment normally goes through.
Can I withdraw to a different method than I deposited with?
Not usually. Anti-money-laundering rules require the money to return the way it came, up to the amount you deposited. Winnings above that can go to a nominated Australian bank account. If you deposited with Neosurf or BPAY, which cannot receive payouts, your withdrawal defaults to bank transfer.
What is the minimum withdrawal at 21 Bit Casino?
A$50 for bank transfer and for e-wallets, and the AUD equivalent of A$50 for crypto. There is no maximum per transaction for verified accounts, but payouts above A$10,000 are usually split across several business days.
How does a 21 Bit Casino deposit appear on my bank statement?
Not as "21 Bit Casino". Card and bank payments show the payment processor descriptor — commonly a generic entertainment or media services name followed by a city and a reference number. Keep the reference number, because support needs it to trace a missing deposit.
Does 21 Bit Casino accept POLi?
POLi is still listed, but most of the big four Australian banks now block it, so it fails more often than it works. PayID does the same job — instant, straight from your bank account — and it is the method we would point you at instead.
18+. Gamble responsibly. Limits and processing times can change without notice — check the cashier before you deposit.
