Visa debit from CBA, Westpac, NAB, ANZ, ING, Macquarie, Up and every other Aussie bank works at our Cambodia eVisa checkout. Mastercard debit is fine too — both process identically to credit cards. The interesting question is FX margin, and not every Aussie debit card charges the same. Here is the bank-by-bank for 2026.

Yes — Visa debit and Mastercard debit cards from every Australian bank work at our Cambodia eVisa checkout. They process identically to credit cards through the same gateway, with the same $80 USD (~$122 AUD) Tourist or $90 USD (~$137 AUD) Business all-in price and the same 3-business-day approval timeline. The interesting question is FX margin. ING Orange Everyday and Macquarie Transaction charge zero FX margin — cheapest path. Up Bank charges a small FX margin (~0.5%). Big-four standard debit (CBA, Westpac, NAB, ANZ) charges 1.5-3% FX margin on USD charges.
Plenty of Australian travellers — especially in the under-35 bracket and especially the backpacker-route crowd planning Cambodia as part of an Indochina loop — do not own a credit card. They run their financial life off a debit card linked to a transaction account, maybe a neobank like Up or Revolut, maybe a no-fee account like ING Orange Everyday, maybe just the standard Visa debit attached to their CBA Smart Access or Westpac Choice. The reasonable question that arrives in our inbox is whether their everyday card actually works for an international visa fee in USD, or whether they need to chase a credit card just for the trip.
The short answer is yes, every Aussie Visa debit card works at our Cambodia eVisa checkout. Mastercard debit too. The processing is identical to a credit card — same gateway, same fields, same approval path. You enter the long card number, the expiry, and the 3-digit CVV on the back, the bank authorises against your available balance (rather than against a credit limit), and the charge clears with the same 3-business-day approval timeline as any other payment method.
What actually differs across Aussie debit cards is the FX margin on the USD-to-AUD conversion, and that varies a lot. ING Orange Everyday and Macquarie Transaction charge zero. Up Bank charges a tiny margin. The big-four standard debit cards charge 1.5-3%. On a $80 USD (~$122 AUD) Tourist eVisa, the difference is between paying $122 AUD flat and paying $125.66 AUD, which is small money but worth knowing about — especially if you have more international charges coming on the Cambodia trip. The Cambodia visa AUD conversion guide for Australians has the wider FX picture.
Every Aussie debit card converts USD to AUD at the network rate (Visa or Mastercard's interbank rate, set daily). The cheap cards stop there. The expensive cards add an FX margin on top — 1.5%, 2%, sometimes 3% — which lands as an extra line on your statement above the base conversion. Here is the bank-by-bank for the seven most-asked-about Aussie issuers, on the $80 USD (~$122 AUD) Tourist eVisa specifically.

Four nights Siem Reap for the temples, three for the harder history of Phnom Penh, three for the slow river days of Kampot, three for the warm water of Koh Rong, one buffer night for the day you wish you had. Here is the honest 14-day Cambodia plan for Aussies in 2026 — costs in AUD, transport in plain English, eVisa timing baked in.
The 12-month Business eVisa extension is the longest commitment-level Cambodia stay Aussies can buy in-country. ~$300–400 USD (~$457–609 AUD) through a Phnom Penh agent on top of the $90 USD (~$137 AUD) Business eVisa, 7–14 business days. Best per-month rate of any extension — but only worth it if you genuinely plan to use the back half of the year.
Three nights in Siem Reap for Angkor, three nights in Phnom Penh for the riverfront and the harder history, one buffer night for the day you wish you had. Here is the honest 7-day Cambodia plan for Aussies in 2026 — costs in AUD, transport in plain English, and the eVisa timing baked in.
ING Orange Everyday is the most-talked-about Aussie debit card for international charges, and for good reason. The card charges zero FX margin on overseas transactions in any currency, including USD. On the $80 USD eVisa, your statement shows around $122 AUD at Visa's interbank rate, with not a cent of FX margin added on top. The catch — you need to meet ING's monthly Orange Advantage criteria (deposit $1,000 AUD per month plus 5 card transactions) for the zero-FX benefit to apply. Most Aussie ING customers meet that automatically through normal day-to-day card use.
Macquarie's everyday Transaction Account ships with a Mastercard debit card that carries no FX margin on international charges. Unlike ING, there are no monthly criteria to maintain the zero-FX benefit — it applies by default. The account is fully fee-free for Aussie residents, the app is genuinely good, and the card works the same way at our Cambodia eVisa checkout as any other Mastercard debit. If you do not already bank with Macquarie, opening an account takes about 15 minutes through the app and you have a digital card ready for Apple Pay or Google Pay before you even receive the physical one in the post.
Up Bank (Bendigo Bank-issued, Mastercard debit) charges a small ~0.5% FX margin on overseas transactions, converting at close to the mid-market rate. The total on a $80 USD eVisa lands around $122.61 AUD, which is a few cents more than ING or Macquarie but still well under the big-four standard debit cards. Up's strength is the app — instant notifications, clean budgeting tools, fast tap-to-pay setup — and for younger Aussie travellers who already bank with Up, the eVisa charge clears smoothly with the same flow as any other Mastercard debit. The trade-off is the tiny margin versus the ING/Macquarie zero-FX baseline.
Plenty of Aussies still run their everyday banking through the big four — CBA Smart Access, Westpac Choice, NAB Classic, ANZ Access Advantage. The Visa debit cards attached to these accounts all work at our Cambodia eVisa checkout, but they all charge an FX margin on USD transactions that lands materially higher than the neobank options.
The published big-four FX margin on USD debit transactions sits between 1.5% and 3% depending on the card tier and the specific product. CBA Smart Access standard debit charges 3% FX (a $1.5 AUD international transaction fee plus 1.5% Visa margin). Westpac Choice is the same 3%. NAB Classic and ANZ Access Advantage both land at 3%. Some premium-tier big-four accounts (CBA Smart Access Plus, Westpac Black) waive the international transaction fee and only charge the underlying Visa margin (~1.5%), but those accounts carry monthly fees that erode the saving.
On the $80 USD Cambodia eVisa, the 3% FX margin adds about $3.66 AUD to the statement — taking the AUD-equivalent from around $122 to around $125.66. On the $90 USD Business eVisa, the 3% margin adds about $4.11 AUD, taking the AUD-equivalent from around $137 to around $141. In absolute terms it is small money. In percentage terms it is meaningful — 3% extra on every international charge across a Cambodia trip adds up.
If you bank with the big four and have time before the trip, opening a secondary ING Orange Everyday or Macquarie Transaction account for international charges takes 15 minutes and saves the FX margin across the whole trip — not just the eVisa fee. If the trip is in three days and you do not have time to onboard a new account, paying the eVisa on your big-four debit costs an extra $3.66 AUD on the Tourist eVisa — which is not worth losing sleep over. The Cambodia first trip planning checklist for Australians has the wider pre-trip prep list.
Worth understanding what happens under the hood when you tap pay with a Visa debit card. The charge runs through the Visa network the same way a Visa credit charge would — same 16-digit card number format, same expiry-and-CVV verification, same merchant authorisation request. What differs is that the bank authorises the charge against your available account balance rather than against a credit limit. If the funds are there, the charge clears. If they are not, the charge declines.
The funds come out of your transaction account immediately on authorisation — there is no settlement-delay buffer like there is on a credit card. So if you pay $122 AUD for the eVisa on a Tuesday morning, the balance in your transaction account drops by $122 AUD on Tuesday morning, not at the end of the statement cycle. That can matter if your account balance is thin and you are about to be paid on the Wednesday. Worth a quick balance check before tapping pay.
Mastercard debit processes identically through the Mastercard network — Macquarie Transaction, Up Bank, Wise, Revolut all run on Mastercard. There is no functional difference at our checkout. The Visa-versus-Mastercard choice on the issuing-bank side is opaque to the merchant; both networks land on our gateway, both clear at the same speed, both have the same fraud-protection posture on Aussie-issued cards.
Daily transaction limits matter. Most Aussie debit cards ship with a default international transaction limit between $1,000 AUD and $5,000 AUD per day. A $122 AUD eVisa is nowhere near that limit, so it is rarely the cause of a decline. But if you are paying for multiple eVisas in one session — a family of four, say — and you have other large charges that day, check the limit in your banking app and lift it temporarily if needed.
Visa debit and Mastercard debit declines at our Cambodia eVisa checkout trace back to one of four causes. Knowing which is hitting you saves a lot of guessing.
The fraud-engine flag is the most common cause once you have ruled out funds, blocks and limits. The cleanest fix is wallet pay with the same debit card — Apple Pay and Google Pay both work with Aussie Visa debit and Mastercard debit, and the tokenised charge presents a different shape to the bank's fraud engine, often clearing where the raw card entry was declined. The PayPal/Apple Pay/Google Pay guide for Australians and the Cambodia eVisa card decline fixes guide both have the wider troubleshooting view.

If you bank with Up, Wise, or Revolut — use it. Tiny FX margin (~0.5%), close to mid-market rate, app-first banking experience. Your statement shows around $122-123 AUD.
If you bank with the big four (CBA, Westpac, NAB, ANZ) and the trip is soon — use your standard Visa debit. The 3% FX margin adds about $3.66 AUD to the eVisa, which is not enough to justify opening a new bank account on a tight timeline. Your statement shows around $125.66 AUD. If the trip is more than two weeks out and you are planning more international charges (hotels, tours, food), the 15-minute ING or Macquarie onboarding is worth it.
