If your bank does not have your tax file number, it withholds tax on your interest at the highest marginal rate. That is the Australian Taxation Office's own wording, and it is the single most expensive consequence of doing arrival admin in the wrong order.
The order that works: passport and visa, then the bank account, then the tax file number, then hand the TFN to the bank and to any employer. Each step needs the one before it.
Most students get this wrong the same way. They land, spend two weeks sorting a room and a SIM, open an account in week three, apply for a TFN in week five, and by then they have already paid a bond with an overseas card.
This post is general information, not financial advice. Bank terms change often, so confirm anything with a dollar sign attached directly with the bank before you rely on it.

| International transaction fee | International transaction fee | Around 3% of each transaction | Every single purchase |
The sequence, step by step
- Passport and visa. Your visa needs to show a start date and duration. NAB requires a passport and visa each valid for at least six months, and a stay of at least six months.
- Start the bank application from home. Two to four weeks before you fly, open the account online and move your first few months of money at an exchange rate you chose.
- Land, get an Australian address and mobile number. Both are required to finish the account. Your accommodation address counts.
- Activate at a branch. Bring the original passport, not a photo. CommBank asks you to do this within 20 days of arriving or the account is closed automatically.
- Apply for the TFN online at ato.gov.au. Free, no documents to post, no agent.
- Give the TFN to your bank the day it arrives. Do this in the app, it takes two minutes.
- Give the TFN to your employer on the tax file number declaration when you start work.
- Set up rent. Direct debit or PayID once the account is live and funded.
Do steps 5 and 6 late and you pay top rate tax on savings interest meanwhile, refundable only through a tax return. Do step 2 late and you spend your first fortnight paying roughly 3% on every card transaction.
What actually goes wrong if you reorder it
The TFN one bites hardest because it is silent. No alert fires. The bank withholds at the top rate on any interest earned, and you notice in July when the annual statement arrives.
The ATO does note you need not provide a TFN if the account earns less than $420 of interest in an income year. On a transaction account you may never cross that. On a savings account holding a semester of living costs, you will.
Visa conditions matter too. The ATO's online registration for temporary visitors excludes visas carrying conditions 8101, 8103 or 8116, the no work conditions. Most student visa holders have work rights, but check your grant letter rather than assuming.
The third failure is a loop. Students delay the account because they think they need an address first, and they cannot sign a lease without an account. The pre arrival application exists to break that loop. Start from home.
Opening an account before you arrive
This is verified and it is the best free thing in this post.
| Bank | Pre arrival opening | Window | Everyday account | Monthly fee waiver |
| Westpac | Yes, online | Arriving within 14 days | Westpac Choice | $5 fee waived for full time tertiary students, and for anyone under 41 |
| CommBank | Yes, via Moving to Australia | Up to 14 days before arrival, or within 12 months after | Everyday Account Smart Access | Waived for the first 12 months when opened through the migrant portal, then waived if under 30 or depositing $2,000 a month |
| NAB | Yes, application started online | Arriving within 30 days, complete in branch within 30 days | NAB Classic Banking | No monthly account fee at all |
| ANZ | Not advertised for pre arrival | Open once you have arrived | ANZ Access Advantage | $5 fee waived for full time students, and for under 25s, or on $2,000 monthly deposits |
Two honest caveats. "Open before you arrive" does not mean "usable before you arrive": the account is dormant until you show a passport in person, so you can deposit into it but not spend from it. And the window is short at Westpac and CommBank, 14 days, so this is a task for after your flights are booked, not when your offer letter lands.
NAB is the simplest on fees because there is no fee to waive and no condition to meet.
CommBank's waiver is the most generous for a young student and the most conditional. Under 30 covers almost every undergraduate. If you are over 30 and not depositing $2,000 a month, the fee is real and you should look elsewhere.
The 100 point identification check
Australian banks verify identity on a points system. You need 100 points, and the grading is what lets you plan ahead.
- Primary, 70 points. A current passport, birth certificate or citizenship certificate. Only one primary document counts, and yours is the passport.
- Secondary with photo and name, 40 points. An Australian driver licence, a government issued licence or permit, or a tertiary student identification card.
- Secondary with name and address, 35 points. Documents from a financial institution or a current employer.
- Secondary, 25 points each. A foreign driver licence, Medicare card, credit card, a utility bill or rates notice in your name, a lease agreement, or educational institution records.
Do the arithmetic before you walk into a branch. Passport 70 plus a foreign driver licence 25 gets you to 95. Add a lease or a university letter and you clear 100. With only a passport you are 30 points short and you will be sent away.
Bring originals. Photocopies and phone photos are refused. If your passport information page is not in English, NAB asks for a NAATI accredited translation, so arrange that at home where it is cheaper.
Fees that add up over a degree
A $5 monthly fee is $60 a year and $180 over a three year degree. Not ruinous, but entirely avoidable.
The bigger number is the foreign transaction fee. ANZ charges 3% of the value of any international transaction charged to an ANZ account, and the majors sit in the same range. Run your first semester on a home country card and you pay roughly 3% on rent, groceries and transport. On $12,000 of spending that is around $360, before your home bank's exchange margin.
Australian ATMs are mostly fine. ANZ does not charge its own customers for withdrawals at non ANZ ATMs inside Australia, though the ATM operator may still charge a fee shown on screen before you confirm. Westpac charges nothing at its own ATMs or Global Alliance partner ATMs overseas, and $5 at other overseas ATMs.
Cash matters less here than in most countries. Australia is close to cashless for student life, so the ATM question comes up mainly at the occasional market stall.
Getting a tax file number
It is free, it has always been free, and there is no faster paid version.
Search results for "TFN application" are full of services charging to fill in a form you can complete yourself in ten minutes. They cannot speed anything up. Some are harvesting your passport and visa details, which is worse than losing the money.
Apply at ato.gov.au. The ATO states that it is free to apply and that you do not need to send documents, because the system checks your visa against your passport with the Department of Home Affairs. You should receive your TFN within 28 days, posted to your Australian address. Do not submit a second application while waiting.
Which means you need a stable postal address first. If you are moving into student accommodation, apply after you move in, not from a hostel.
Paying rent and bond
Most student accommodation providers and almost all private landlords want an Australian account, because direct debit, BPAY and Osko run on the domestic system and none accept a foreign card.
The tools you will actually use:
- Direct debit. You authorise the provider to pull an agreed amount on an agreed day. Standard for weekly or fortnightly rent in purpose built student accommodation.
- PayID and Osko. PayID replaces the BSB and account number with a mobile number or email. NAB puts Osko settlement at 15 to 30 seconds, seven days a week. Useful for splitting bills with a housemate, and the favourite tool of scammers precisely because it is instant and irreversible.
- BPAY. A biller code and reference number, used for utilities and some accommodation providers.
Bond lodgement works differently by state, and the money should not stay with your landlord. In Victoria the rental provider must lodge the bond with the Residential Tenancies Bond Authority within 14 days of receiving it, and the RTBA holds it in trust until the agreement ends. Other states have equivalent authorities. A landlord who says they will "just hold the bond" is a warning sign in most of the country, worth checking against your state's rules and your tenant rights in private rentals.
If you are still choosing where to live, the guide to booking student housing before you arrive assumes you will have an account ready at move in.
The scam warning, which is not decoration
Never send money for accommodation before you have a local account. The reason is recoverability: money sent by international transfer or instant PayID to a stranger is gone the moment it lands. And never transfer a bond to a private individual's account without verifying the property exists and that the person owns or manages it. Ask for the bond lodgement reference. A legitimate provider gives you one.
A second scam runs in the other direction. In a media release dated 19 November 2025, the Australian Federal Police warned departing international students not to sell or share their bank accounts and identity documents, after criminal networks offered $200 to $500 for account access plus a commission on laundered funds. Detective Superintendent Marie Andersson said what looks like a harmless favour can end in criminal charges, visa cancellation and a permanent ban from returning. Money laundering carries a maximum penalty of life imprisonment in Australia.
So: do not let anyone else use your account, do not accept money you were not expecting and forward it on, and close your Australian account properly when you leave. If something has already gone wrong, our guide to common housing scams covers the next steps.
Frequently asked questions
Can I open an Australian bank account before I arrive?
Yes. Westpac lets you set up an account online if you will arrive within 14 days, CommBank lets you open an Everyday Account Smart Access up to 14 days before arrival through Moving to Australia, and NAB lets you start an application if you arrive within 30 days. All require identity verification in person after you land.
Do I need a tax file number to open a bank account?
No, you can open and use an account without one. But if the bank does not hold your TFN it withholds tax on interest at the highest marginal rate, so add it as soon as it arrives. The ATO notes you need not supply one if the account earns under $420 of interest a year.
How long does a tax file number take and does it cost anything?
It is free and should arrive within 28 days of the ATO receiving your completed application. Apply directly at ato.gov.au. No agent, no fee, no documents to post.
What ID do I need for the 100 point check as an international student?
Your current passport is worth 70 points. An Australian tertiary student card adds 40, a foreign driver licence 25, and a lease or educational institution document 25. Passport plus any two clears 100. Bring originals, not copies.
Which bank is cheapest for international students in Australia?
NAB Classic Banking is simplest, with no monthly account fee and no conditions. CommBank waives its fee for the first 12 months when opened through its migrant service, then for anyone under 30. ANZ and Westpac waive theirs for full time students. Branch location near campus is a fair tiebreaker.
Can I pay my rent and bond with my overseas card?
Usually not. Most providers require direct debit, BPAY or a domestic transfer, none of which accept a foreign card. Where one is accepted you pay roughly 3% in international transaction fees on every payment, plus an exchange margin.
Do I need an Australian address before I can open the account?
You need one to finish the process, not to start it. The application can be lodged from your home country, and you supply the Australian address and mobile number when you verify your identity in branch.
Bottom line
Start the bank application two to four weeks before you fly, activate it in a branch in your first week, apply for the TFN once you have a stable postal address, and hand that TFN to the bank the day it arrives. Four steps, in that order, and the whole thing costs nothing.
The caveat is that pre arrival windows are short and fee waiver conditions change without much announcement. A waiver that applies to under 30s today is a policy, not a promise. Check the bank's own current page before you decide, especially if you are over 30, when several of these waivers stop applying.
The expensive mistakes here are not dramatic. A 3% fee paid quietly on every transaction for a semester, and top rate tax withheld because a two minute app task sat undone. Neither sends you an alert.
