How to Open an Australian Bank Account (2026 Latest Big 4 Banks Comparison)

Banking in Australia: A Guide to Opening Your First Account

One of the first things you will notice when arriving in Australia is that "cash is no longer king." From paying for a flat white at a local café to receiving your first paycheck, everything runs through a digital bank account. However, with dozens of banks to choose from, picking the right one can feel overwhelming.

If you have already secured your Tax File Number (TFN), you are in a great position to open an account and avoid the high tax rates on any interest you earn. Let’s dive into how the Australian banking system works and which "Big 4" bank might be the right fit for your lifestyle.

The "Big 4" Banks: Which One Should You Choose?

Australia’s banking landscape is dominated by four major institutions. While many smaller "neobanks" exist, most migrants and students start with one of the majors because they offer the most branches and ATMs across the country.

1. Commonwealth Bank (CBA): Often called "CommBank," they are known for having the best mobile app in Australia. They make it very easy for students and migrants to open accounts online before they even arrive in the country.
   
   

2. Westpac: This is Australia’s oldest bank. In 2026, they are offering competitive cashback deals (sometimes up to 👀 $50) for new arrivals who open a "Choice" account and make a deposit within the first 10 days.
   
   

3. ANZ Plus: A modern, app-only version of the traditional ANZ account. It is popular because it has zero monthly fees and great built-in tools to help you track your spending by category.
   
   

4. National Australia Bank (NAB): NAB is the only bank among the Big 4 that offers a "classic" transaction account with no monthly account-keeping fees for everyone, not just students or young people.

How to Open an Account (The Smart Way 👍)

Most newcomers don't realize you have two main ways to get started.

Option A: The Pre-Arrival Method (Online)

If you are still overseas but have your visa ready, banks like CBA allow you to open an account online up to three months before you land.

• The Benefit: You can transfer your savings to Australia early to take advantage of exchange rates.
  
  

• The Catch: You can deposit money, but you cannot withdraw it until you arrive in Australia and visit a branch in person with your passport to "identify" yourself.
  
  

Option B: The In-Branch Method (After Arrival)

If you are already here, simply walk into any branch.

• Pro-Tip: If you do this within the first six weeks of arriving in Australia, your passport is usually the only primary ID you need. 👍If you wait longer than six weeks, you will need to provide more documents to meet the "100-point ID check."

What You Need to Bring to the Bank

When you walk into a branch to finalize your account or open a new one, bring these items:

• Passport: Your primary proof of identity and visa status.
  
  

• Tax File Number (TFN): Provide this immediately. If the bank doesn't have it, they must legally withhold tax from any interest you earn at the highest rate (45%).
  
  

• Proof of Enrollment: If you are an international student, bring your CoE (Confirmation of Enrollment) to ensure they waive your monthly fees.
  
  

• Australian Mobile Number: You will need this to set up your mobile banking app and receive security codes.

A Local's Perspective: Hidden Costs to Watch Out For

1. Account-Keeping Fees: Except for NAB and ANZ Plus, most banks charge $4–$10 a month. Usually, this is waived if you are a student or deposit a certain amount (like $2,000) each month.
   
   

2. Overseas Transaction Fees: Most standard debit cards charge around 3% if you buy something online from a foreign website or use your card while traveling back home.
   
   

3. Paper Statements: Most banks now charge a fee if you want them to mail you a paper statement. Opt for "E-statements" in your app settings to save money.

Final Checklist for Your First Week

• Set up "PayID": Once your account is open, link it to your mobile number(or email). This allows people to send you money instantly using just your phone number. (or email)
  
  

• The "100-Point" Check: If you aren't a new arrival, you'll need multiple IDs (Passport + Medicare + Bank Statement from another bank) to equal 100 points. (You’ll need this 100-point ID check for most official processes where you must prove your identity. A bank card or bank statement usually carries a significant number of points, which makes it essential.)
  
  

• Apply for a Savings Account: Don't keep all your money in your "Transaction" (everyday) account. It earns zero interest. Open a "Savings" account alongside it to earn around 4-5% interest (based on 2026 rates).
