Big four or challenger: where to bank online.

How Australia’s big four banks compare with ING, Macquarie, ubank and Up for everyday online banking — plus switching and security basics. General information, not financial advice.

General information only — not financial advice. The pattern across Australian banking is consistent: the big four (CommBank, Westpac, NAB, ANZ) trade convenience — branches, cash handling, every product under one roof — for middling rates, while the challengers (ING, Macquarie, ubank, Up) compete hard on fees, savings rates and app quality. Plenty of Australians simply use both: transactions where the app feels best, savings where the rate is.

Key takeaways

  • Compare on four things: app quality, fees, savings rate, and access to cash/branches when you need them.
  • Bonus savings rates usually have monthly hoops — deposit minimums, card-use counts. Read the conditions.
  • Switching is easier than it looks; the real work is moving direct debits.
  • Security beats rate-chasing: strong unique passwords, app-based MFA, and never act on a "bank" phone call — hang up and call back via the official number.

What the big four actually give you

The majors’ pitch is completeness. A CommBank, Westpac, NAB or ANZ login covers transactions, savings, cards, loans and insurance in one place, with branches and ATMs behind it when something needs a human or a cash deposit. CommBank’s app in particular is widely regarded as the most polished of the majors, which matters more than it sounds — it’s the screen you’ll see daily.

The trade-off is sharpness. Headline savings rates and fee waivers at the majors are rarely market-leading, because they don’t have to be. If your banking is complicated — business accounts, offset loans, frequent cash — the convenience can be worth it. If your banking is a pay cheque in and spending out, you’re paying for infrastructure you don’t use.

Where the challengers win

ING made its name on fee-free everyday accounts and bonus savers; Macquarie’s retail accounts pair strong rates with a genuinely slick app; ubank (NAB’s digital brand) and Up (built on Bendigo’s licence) compete on app experience — Up’s savers, round-ups and spending insights are the best budgeting tools in the market, which is why younger savers cluster there.

The catch to read for: bonus rates with conditions. "Deposit $1,000 a month and make five card purchases" is typical — miss a hoop, get the base rate. None of this is hidden, but it rewards people who actually read the conditions page. Our Banking & Finance comparison notes who owns each brand — several "independents" are big-four subsidiaries, which matters for how you spread accounts.

Switching and staying safe

Switching is mechanically simple — open the new account, move the balance, redirect your pay. The real work is the direct-debit audit: list everything attached to the old account (subscriptions, insurers, utilities), move them, and keep the old account open with a buffer for a month. PayID makes the inbound side easy to update.

Security is the part that outranks every rate comparison. Use a unique password and app-based MFA on every bank login; prefer the bank’s own app over browser bookmarks on shared computers; and treat every unexpected "your bank calling about fraud" call as hostile until proven otherwise — hang up and call the number on the bank’s website or your card. Banks never need your full password or a code read over the phone. For current scam patterns, Moneysmart and Scamwatch are the authoritative free references.

Frequently asked questions

Which bank has the best app in Australia?
"Best" is partly taste, but the recurring answers are CommBank among the majors and Up among the digital banks — polish on one side, budgeting tools on the other. Most banks let you browse app-store screenshots and reviews before opening anything; our Banking top 10 compares the field.
Are digital banks like ubank and Up safe?
They operate under full Australian banking licences — ubank is part of NAB and Up operates on Bendigo & Adelaide Bank’s licence — so deposits sit within the same regulated system as the majors, including the Financial Claims Scheme’s protection (currently up to $250,000 per account holder, per licensed bank). Note that brands sharing one licence share that cap.
Should I switch banks to chase a better savings rate?
That’s a personal decision we can’t make for you — this site publishes general information, not financial advice. The general considerations: the real rate after bonus conditions, fees, how much the app matters to you, and whether the gain justifies the direct-debit shuffle. Moneysmart’s calculators help you put numbers on it.
