How to Call NAB From Abroad
9/2/2026
Quick answer: Call NAB's standard international line at +61 3 8641 9083, Monday to Friday 8am to 7pm and weekends 9am to 6pm AEST/AEDT. NAB also lists toll-free numbers for a long list of countries, starting with 00800 0825 1131, though availability depends on your local network.
NAB's toll-free coverage is broader than most banks, but not universal
NAB publishes country-specific toll-free access codes for a wide range of countries, including variants for Brazil, Hong Kong, Singapore, South Korea, and Japan, on top of the general 00800 0825 1131 code. Whether it actually connects for free depends on your carrier and network, which is why NAB also keeps a standard international number as a fallback that works regardless.
