The Big Four, and how they differ from abroad
Australia's banking sector is dominated by four major banks, and all four have moved past the "13-number that only works domestically" problem in different ways. CommBank and Westpac run broad overseas banking lines. NAB layers in country-specific toll-free access on top of a standard fallback. ANZ's overseas support leans specifically toward card and security issues rather than general banking questions.

Frequently asked questions
Which Australian bank is easiest to reach from abroad? CommBank and Westpac both run round-the-clock or near round-the-clock general banking lines. ANZ's overseas support is narrower, focused on card and security issues rather than general questions.
Are Australian bank overseas numbers toll-free? Mostly no, they're standard chargeable numbers, which is why they work from anywhere. NAB and Westpac are exceptions for callers in specific countries.
Do I need a different number for a lost or stolen card? Yes, for Westpac and ANZ specifically. CommBank and NAB use the same general number for card issues as everything else.
How do I dial an Australian number from abroad? Replace the leading 0 with +61. Australian "13" numbers don't work from abroad at all, use the specific overseas number your bank publishes instead.
